Any and all applications for which a foreign or domestic priority claim is identified in the Application Data Sheet as filed with the present application are incorporated by reference and made a part of this specification.
The present disclosure relates to cooling and ventilation systems for building structures.
Heating and cooling the space in residential and commercial buildings accounts for a primary share of building energy consumption. Occupants or persons otherwise associated with building heating and cooling may either not know when it is optimum to use a heating and cooling system or otherwise not properly utilize the heating and cooling system.
Attic fans are intended to cool hot attics by exhausting super-heated air from the attic and drawing cooler outside air into the attic. Attic fans are mounted on an attic gable wall or slope of a roof and push hot attic air through a vent to the outside. Overheated attics can cause premature failure of building materials (e.g., roofing, sheathing, joists, rafters, insulation, air conditioning ducts, etc.). Cooling the attic can reduce the cost of cooling the living space. Attic fans can also help to control the damage caused by moisture and humidity in the air.
When the outside ambient air temperature is lower than the internal air temperature, outside ambient air can instead be used to effectively cool the home or building structure, including an attic of the building structure, reducing the need to run a costly air conditioning system. Further, air conditioning systems merely circulate air located within a building structure, and do not bring any outside air, so any harmful environmental elements (e.g. dust, disease, chemicals) may remain within the building structure. Temperature within a spaced of the building structure can get high and warm other parts of the building structure. Running attic fans can bring in relatively cooler ambient air and reduce heating of the building structure from the attic. Further, air within certain spaces of the building structure like attics may not circulate well. Attic fans can pull air through spaces like attics to, for example, reduce temperature and humidity in the attic and reduce damage to the infrastructure of the building structure.
A whole house fan can be used to move air through the building structure when desired outside and/or inside conditions allow. Whole house fans include one or more high cubic feet per minute (cfm) fans, typically placed in the attic of a building structure, and function by creating a negative static pressure inside of the building structure to draw air in from the outside. The outside air is moved through the ceiling into the attic where the air is exhausted out through a vent by positive static pressure in the attic or upper floor. Louvered shutters can be placed over the vent to prevent cooled or heated air from escaping when the whole house fan is not in use. Whole house fans move large amounts of air and allow for the entire building structure air volume to be recycled with multiple air exchanges per hour, removing latent heat within the building structure. Advantageously, whole house fans typically require less energy than air conditioning systems and can reduce the need for air conditioning, therefore reducing energy consumption while providing a comfortable space for building occupants.
An attic fan can achieve less over heating of an attic, which can reduce energy cost of cooling of attic and living space, helping reduction of premature failure of roofing, structure, wood members, insulation, etc., as well as reducing moisture and humidity problems in attics. Attic fan assemblies disclosed herein can use a combination of solar generated power and grid power to power the fans. The attic fan assemblies can use as much power as solar panels generate. The rest of the power can be supplemented with grid power to provide the desired power to the attic fan. The desired power provided to the fan can depend on temperature, such as the temperature of the attic space, which can determine the desired operation speed of the fan and the desired power to be provided to the fan. Energy generated by solar panels is directed to the attic fan and can be supplemented by grid power to reach desired power based on temperature. Accordingly, the multifunction systems and methods disclosed herein can adapt the energy drawn from grid power in real time based on temperature and power generated by the solar panels. In some cases, the multifunction systems and methods disclosed herein can adapt the energy drawn from grid power in real time based on desired fan speed and power generated by the solar panels. In some cases, speed or operation of the fan can be determined based on temperature and/or humidity in the attic and/or ambient environment. In some cases, the attic fan can operate just on solar power. In some cases, the attic fan can operate just on grid power.

The Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of any subject matter described herein.
Embodiments of the present disclosure provide for a fresh air cooling and ventilating system. The fresh air cooling and ventilating system can include a motorized whole house fan, a vent system, user device(s), connection(s) to thermostat(s) or other devices that control an air conditioning system, and/or controller(s) that control the fresh air cooling and ventilating system and/or air conditions system. The use of a fresh air cooling and ventilating system in a building structure presents several advantages, including decreased energy usage and greater circulation of fresh ambient air, thereby reducing temperature and humidity in the building structure.
The one or more controllers can include an attic fan controller that operates the attic fan. The attic fan controller can receive information via a connection to the internet in addition to receiving input from temperature and other kinds of sensors both inside and outside of a building structure. The attic fan controller can receive temperature data via temperature sensors connected to the attic fan controller. The temperature sensors can be located in and around the building structure, including in the attic space, the living/interior space, and the ambient environment outside the building structure. In some embodiments, the attic fan controller can receive temperature data corresponding to an outside temperature value from an online source via a connection to the internet. In some embodiments, the attic fan controller can receive any temperature data discussed herein via a temperature sensor and/or the internet. The temperature sensors can be connected via any wired or wireless connection discussed herein.
In some embodiments, the attic fan controller can receive a humidity value corresponding to the humidity level inside the building structure, including the attic, and/or in the ambient air outside of the building structure. The attic fan controller can receive the humidity value either from a humidity sensor in wired or wireless connection with the attic fan controller or from an online source via a connection to the internet. The humidity sensor(s) can be located in and around the building structure, including in the attic space, the living/interior space, and the ambient environment outside the building structure.
As used herein, humidity is used in its broad and ordinary sense and includes, for example, a measurement of the concentration of water vapor in the air. A relative humidity or humidity value as used herein falls between 0-100% (percent). High humidity in the interior air of a building structure can cause water damage to the interior of a building structure as well occupant discomfort.

For example, the smartphone application 166 can allow a user to select modes of operation as discussed herein.
In some embodiments, the smart control hub 700 can connect to other devices over a Bluetooth Low Energy (BLE) 5.0/mesh. In some embodiments, the smart control hub 700 can include a Wi-Fi 2.4/5 GHz Chip. In some embodiments, one or more components of the smart control hub 700 can receive 17 A of current, for example, from standard building electrical power systems. In some embodiments, the smart control hub 700 can transmit or receive data across about 100 feet or more of direct line communication. The smart control hub 700 can transmit or receive data across about 80 feet or more of direct line communication (e.g., through average household obstructions). In some embodiments, the smart control hub can operate at about 120 volts AC and a frequency of about 60 Hz. In some embodiments, the smart control hub 700 can output up to about 24 volts at about 2.1 amps DC power. The smart control hub 700 can be adapted to have an operating temperature between about −20° C. to +80° C. The smart control hub 700 can be adapted to have a storage temperature between about −40° C. to +80° C. and a storage humidity of less than about 90% relative humidity (non-condensing). The smart control hub 700 can comply with Restriction of Hazardous Substances (RoHS).
In some embodiments, the smart control hub 700 can be in communication with a speed sensor of attic fans 116, 118 and receive speed signals from the speed sensor to control the speed of the attic fan motor(s) at a desired fan speed (e.g., at a speed selected by a user such as via the smartphone application 166 and/or web application). In some embodiments, the speed sensor can be a Hall effect sensor that is configured to detect the passing of a magnet. For example, the speed sensor can detect a change in a magnetic field as the magnet approaches and moves away from the speed sensor. The magnet can be attached to a rotating portion of attic fans 116, 118 such as the fan drive shaft. The speed sensor can be attached to a fixed portion of attic fans 116, 118 such as a frame. The speed sensor can be positioned such that the magnet passes by the speed sensor as the drive shaft rotates (e.g., each time the drive shaft completes one full rotation). As the magnet passes by the speed sensor, the speed sensor can generate a voltage pulse (or digital pulse or the like depending on the sensor), with each pulse corresponding to rotation of the drive shaft. In some embodiments, if a single magnet is used, each pulse can correspond to one complete rotation. In some embodiments, more than one magnet can be used, and each pulse can correspond to a portion of a complete rotation. The frequency at which the magnet passes the speed sensor (e.g., the frequency at which pulses are generated) can correspond to a speed at which attic fans 116, 118 rotate. The smart control hub 700 can determine the fan speed based on the frequency of pulses and/or the time period between pulses.
In some embodiments, the smart control hub 700 can be connected to a voltage converter such as voltage converter 170. The voltage converter can be connected to the smart control hub 700 via a power cord that connects to a power connector or port of the smart control hub 700 to supply power to the smart control hub 700. In some embodiments, the smart control hub 700 may include a voltage converter connector such as a DC round power connector. The DC round power connector can be rated for 3000 milli amps of current. The voltage converter can be connected to AC power of a building structure (e.g., building structure 106) that is connected to an electrical utility power grid (e.g., a public electrical grid). The voltage converter can convert the AC power to DC power to power the attic fan 116, 118. The voltage converter can have an electric grid input of 120 volts AC to 220 volts AC. The voltage converter can convert the electric grid input into a converted DC power output of ranging, for example, from 12 volts at 1 amp DC power to 48 volts at 20 amps DC power. In some embodiments, the voltage converter can supply up to 24 volts at 5 amps DC power. Correspondingly, the attic fans 116, 118 discussed herein can have power input ranging, for example, from 12 volts at 1 amp DC power to 48 volts at 20 amps DC power. In some embodiments, the attic fans 116, 118 can have power input up to 22 volts at 2.1 amps DC power.
In some embodiments, the smart control hub 700 can include a voltage regulator such as voltage regulator 172. The voltage regulator can receive the converted DC power from the voltage converter. The voltage regulator can supply DC power to the attic fan assembly 116, 118 at a predetermined voltage. A controller of the smart control hub 700 can be in two-way communication with the voltage regulator to receive signals indicative of the converted DC power supplied to the voltage regulator and to send control signals to the voltage regulator. The controller of the smart control hub 700 can control the voltage regulator to cause the voltage regulator to supply DC power to the attic fan assembly 116, 118 at the predetermined voltage. In some embodiments, the controller of the smart control hub 700 can control the voltage regulator to cause the voltage regulator to supply up to 22 volts at 2.1 amps DC power to power the attic fans 116, 118.
In some embodiments, the smart control hub 700 can be connected to a solar panel assembly such as solar panel assembly 136. The solar panel assembly can be connected to the smart control hub 700 via a power cord that connects to a solar panel connector or port of the smart control hub 700 to supply power to the smart control hub 700. In some embodiments, the smart control hub 700 may include a DC solar panel port such as a female M12 2-pin locking thread. The solar panel assembly can convert solar energy into electrical power and generate a DC power output from the solar energy. In some embodiments, the solar panel assembly can output up to 26 volts at 2.5 amps DC power. The controller of the smart control hub 700 can monitor the solar-generated DC power (e.g., voltage of the solar-generated DC power). The solar-generated DC power can be directed directly to the attic fan assembly 116, 118. In some embodiments, the solar-generated DC power from the solar panel assembly can be directed to the voltage regulator that then directs the solar-generated DC power to the attic fan assembly 116, 118.
As depicted in
At block 804, the predetermined attic temperature value may be fixed or programmable. In some embodiments, the predetermined attic temperature value can be set and/or modified by the user utilizing a smartphone application and/or web application, or by the manufacturer or the system or the person installing the system or any combination of the foregoing. In some embodiments, the predetermined attic temperature value, can be 182 degrees Fahrenheit. A temperature of 182 degrees Fahrenheit or above may indicate that there is a fire in the building structure. In such a scenario, the ventilating system 100 is designed to shut down to prevent air from being drawn into the building structure and further feeding any fire that may be occurring in the building structure. The predetermined attic temperature is not limited to 182 degrees Fahrenheit, but can be set at any temperature value, including 160, 165, 170, 170, and 180 degrees Fahrenheit. For example, under typical operating conditions, the attic temperature may reach between 120 and 140 degrees Fahrenheit. In some examples, the predetermined attic temperature value may be a maximum attic temperature at which the system 100 can operate fans 116, 118.
For building structures positioned in excessively hot conditions, such as a desert, the attic temperature may reach up to 160 degrees Fahrenheit. In some embodiments, the smartphone application 166, web application, can allow the user to modify the predetermined attic temperature, for example, depending on the location of the system 100. The system 100 may automatically modify the predetermined attic temperature depending on the location of the building structure within which the system 100 is installed. This feature is advantageous because it can prevent the system from exacerbating a fire that may be occurring in the building structure.
In response to a determination at block 804 that the attic temperature is not within operating parameters, the controller may proceed along control logic flow 800 to block 890. For example, at block 890, the controller can send a command/operation signal causing the attic fans 116, 118 to turn off. In response to a determination at block 804 that the attic temperature is within operating parameters, the controller may proceed along the control logic flow 800 to block 806. In some embodiments, at block 806, the controller can determine whether the humidity level in the attic of the building structure is within predetermined parameters for operation of the ventilating system 100. In some embodiments, the controller can receive a humidity level value corresponding to the humidity level in the attic of the building from a humidity sensor located in the attic of the building. The controller can compare the attic humidity level value with a predetermined attic humidity level value. In some embodiments, at block 806, the controller can determine whether the attic humidity level is within operating parameters based on a comparison between the attic humidity level value and the predetermined attic humidity level value. For example, the controller may determine that the attic humidity level is not within operating parameters based on a determination that the attic humidity level value is less than the predetermined attic humidity level value. In some examples, the controller may determine that the attic humidity level is within operating parameters based on a determination that the attic humidity level value is greater than the predetermined attic humidity level value.
At block 806, the predetermined attic humidity level value may be fixed or programmable. In some embodiments, the predetermined attic humidity level value can be set and/or modified by the user utilizing a smartphone application and/or web application, or by the manufacturer or the system or the person installing the system or any combination of the foregoing. In some embodiments, the predetermined attic humidity level value can correspond to a predetermined humidity shut-off percentage. The predetermined humidity shut-off percentage can be 90%. For example, the controller may determine that the attic humidity level value is less than 90%. In some examples, the controller may determine that the attic humidity level value is at or greater than 90%. The predetermined humidity shut-off percentage is not limited to 90%, but can be set to any humidity level parameter or value.
In response to a determination at block 806 that the attic humidity level value is not within operating parameters, the controller may proceed along the control logic flow 800 to block 890. For example, at block 890, the controller can send a command/operation signal causing the attic fans 116, 118 to turn off.
In response to a determination at block 806 that the attic humidity level value is within operating parameters, the controller may proceed along the control logic flow 800 to block 808. In some embodiments, at block 808, the controller can determine whether solar panel voltage satisfies a voltage threshold. The solar panel voltage can correspond to DC output voltage generated by a solar panel assembly such as solar panel assembly 136. The controller can monitor the solar-generated DC voltage level and receive a value corresponding to the solar-generated DC voltage level. In some embodiments, the controller can determine whether the solar-generated DC voltage level satisfies the voltage threshold based on a comparison between the solar-generated DC voltage level value and a predetermined voltage level value. For example, the controller may determine that the voltage threshold is satisfied based on a determination that the generate DC voltage level value is at or greater than the predetermined voltage level value. In some examples, the controller may determine that the voltage threshold is not satisfied based on a determination that the solar-generated DC voltage value is less than the predetermined voltage level value.
At block 808, the predetermined voltage level value may be fixed or programmable. In some embodiments, the predetermined voltage level can be set and/or modified by the user utilizing a smartphone application and/or web application, or by the manufacturer or the system or the person installing the system or any combination of the foregoing. In some embodiments, the predetermined voltage level value can be 5.5 volts. The predetermined voltage level value is not limited to 5.5 volts, but can be set to any voltage value.
In response to a determination at block 808 that the solar-generated DC voltage value does not satisfy the voltage threshold, the controller can proceed along the control logic flow 800 to block 810. At block 810, in some embodiments, the controller can determine whether the system 100 is in a nighttime setting. A nighttime setting can correspond to a mode of operating attic fans 116, 118 at times corresponding to when there is little or no DC voltage generated by the solar panel assembly. In some examples, the system 100 may be in the nighttime setting when there is less than 1 volt of solar-generated DC voltage. In some embodiments, the nighttime setting can include at least two modes of operation. For example, a first mode of operation can correspond to an off mode. In some examples, a second mode of operation can correspond to a grid mode.
In some embodiments, at block 810, the controller may determine that the system 100 is operating in a nighttime setting corresponding to an off mode. The off mode can include turning off or disallowing from running the attic fans 116, 118. In response to the determination at block 810 that the system 100 is operating in the off mode, the controller may proceed along the control logic flow 800 to block 890. For example, at block 890, the controller can send a command/operation signal causing the attic fans 116, 118 to turn off.
In some embodiments, at block 810, the controller may determine that the system 100 is operating in a nighttime setting corresponding to a grid mode. The grid mode can include operating attic fans 116, 118 based on voltage received from the electrical utility power grid of the building structure (e.g., voltage received from a voltage converter). For example, while in the grid mode, attic fans 116, 118 can be supplied with voltage from the electrical utility power grid required to run at the fan speed dictated by the attic temperature. In response to the determination at block 810
that the system 100 is operating in the grid mode, the controller may proceed along the control logic flow 800 to block 814.
At block 814, in some embodiments, the controller can determine whether the temperature in the attic satisfies an attic temperature threshold. In some embodiments, the controller can receive a temperature value corresponding to the temperature in the attic of the building from a temperature sensor located in the attic of the building. The controller can compare the attic temperature value with a predetermined attic temperature value. In some embodiments, at block 814, the controller can determine whether the attic temperature threshold is satisfied based on a comparison between the attic temperature value and the predetermined attic temperature value. For example, the controller may determine that the attic temperature threshold is satisfied based on a determination that the attic temperature value is greater than the predetermined attic temperature value. In some examples, the controller may determine that the attic temperature threshold is not satisfied based on a determination that the attic temperature value is less than the predetermined attic temperature value.
At block 814, the predetermined attic temperature value may be fixed or programmable. In some embodiments, the predetermined attic temperature value can be set and/or modified by the user utilizing a smartphone application and/or web application, or by the manufacturer or the system or the person installing the system or any combination of the foregoing. In some embodiments, at block 814, the predetermined attic temperature value can correspond to a low-speed temperature value. The low-speed temperature value can correspond to an attic temperature value at which the controller causes attic fans 116, 118 to run at low speed (e.g., at a low RPM). In some embodiments, a low fan speed can include a range of speeds.
In response to a determination at block 814 that the attic temperature satisfies the attic temperature threshold, the controller may proceed along the control logic flow 800 to block 822. At block 822, in some embodiments, the controller can determine a speed at which to run attic fans 116, 118 based on the temperature in the attic. In some embodiments, at block 822, the controller may determine the speed to which run attic fans 116, 118 based on a comparison between the attic temperature value and a predetermined attic temperature value. In some embodiments, at block 822, the controller may implement a series of determinations such as according to multiple different predetermined attic temperature values or ranges. For example, a first predetermined attic temperature value may correspond to a high-speed temperature value or range. In some examples, a second predetermined attic temperature value may correspond to a medium-speed temperature value or range. In some examples, a third predetermined attic temperature value may correspond to a low-speed temperature value or range such as the low-speed temperature value discussed with reference to block 810.
In some embodiments, at block 822, predetermined attic temperature value(s) may be fixed or programmable. In some embodiments, predetermined attic temperature value(s) can be set and/or modified by the user utilizing a smartphone application and/or web application, or by the manufacturer or the system or the person installing the system or any combination of the foregoing. In some embodiments, at block 822, a high-speed temperature value can correspond to an attic temperature value at which the controller causes attic fans 116, 118 to run at high speed (e.g., high RPM). In some embodiments, a high fan speed can include a range of speeds. In some embodiments, a high fan speed range can include a limit such as a lower and upper limit. For example, a high fan speed range can include a fan speed of about 800 RPM to about 950 RPM. In some embodiments, at block 822, a medium-speed temperature value can correspond to an attic temperature value at which the controller causes attic fans 116, 118 to run at medium speed (e.g., medium RPM). In some embodiments, a medium fan speed can include a range of speeds. In some embodiments, a medium fan speed range can include a limit such as a lower and upper limit. For example, a medium fan speed range can include a fan speed of about 650 RPM to about 799 RPM. In some embodiments, at block 822, a low-speed temperature value can correspond to an attic temperature value at which the controller causes attic fans 116, 118 to run at low speed (e.g., low RPM). In some embodiments, a low fan speed can include a range of speeds. In some embodiments, a low fan speed range can include a limit such as a lower and upper limit. For example, a low fan speed range can include a fan speed of about 500 RPM to about 649 RPM. In some embodiments, at block 822, there may be a five-degree temperature delta between low-, medium-, and high-speed temperature values.
In some embodiments, at block 822, the controller may determine to run attic fans 116, 118 at a high fan speed based on a determination that the attic temperature is greater than the first predetermined attic temperature value. The controller may determine to run attic fans 116, 118 at any high speed within the high-speed range. For example, the controller may determine to run attic fan 116, 118 at a speed corresponding to 800 RPM. A speed of 800 RPM can correspond to an attic fan motor load of 13.1 volts at 1.41 amps DC power. For example, the controller can cause a voltage converter (e.g., voltage converter 170) to provide attic fans 116, 118 with 13.1 volts at 1.41 amps DC power. In some examples, the controller may determine to run attic fan 116, 118 at a speed corresponding to 950 RPM. A speed of 950 RPM can correspond to an attic fan motor load of 22 volts at 2.1 amps DC power. For example, the controller can cause the voltage converter to provide attic fans 116, 118 with 22 volts at 2.1 amps DC power. In response to the determination at block 822, the controller may proceed along the control logic flow 800 to block 880. For example, at block 880, the controller can send a command/operation signal causing the attic fans 116, 118 to run at the high speed. In some examples, the controller can send a command/operation signal causing the attic fans 116, 118 to run at the upper limit of the high-speed range.
In some embodiments, at block 822, the controller may determine to run attic fans 116, 118 at a medium fan speed based on a determination that the attic temperature is less than the first predetermined attic temperature value and greater than the second predetermined attic temperature value. The controller may determine to run attic fans 116, 118 at any medium speed within the medium-speed range. For example, the controller may determine to run attic fans 116, 118 at a speed corresponding to 650 RPM. A speed of 650 RPM can correspond to an attic fan motor load of 11.1 volts at 1 amp DC power. For example, the controller can cause the voltage converter to provide attic fans 116, 118 with 11.1 volts at 1 amp DC power. In some examples, the controller may determine to run attic fan 116, 118 at a speed corresponding to 790 RPM. A speed of 799 RPM can correspond to an attic fan motor load of 13 volts at 1.4 amps DC power. For example, the controller can cause the voltage converter to provide attic fans 116, 118 with 13 volts at 1.4 amps DC power. In response to the determination at block 822, the controller may proceed along the control logic flow 800 to block 880. For example, at block 880, the controller can send a command/operation signal causing the attic fans 116, 118 to run at the medium speed. In some examples, the controller can send a command/operation signal causing the attic fans 116, 118 to run at the upper limit of the medium-speed range.
In some embodiments, at block 822, the controller may determine to run attic fans 116, 118 at a low fan speed based on a determination that the attic temperature is less than the second predetermined attic temperature value and greater than the third predetermined attic temperature value. The controller may determine to run attic fans 116, 118 at any low speed within the low-speed range. For example, the controller may determine to run attic fans 116, 118 at a speed corresponding to 500 RPM. A speed of 500 RPM can correspond to an attic fan motor load of 10 volts at 0.5 amps DC power. For example, the controller can cause the voltage converter to provide attic fans 116, 118 with 10 volts at 0.5 amps DC power. In some examples, the controller may determine to run attic fan 116, 118 at a speed corresponding to 649 RPM. A speed of 649 RPM can correspond to an attic fan motor load of 11 volts at 0.9 amps DC power. For example, the controller can cause the voltage converter to provide attic fans 116, 118 with 11 volts at 0.9 amps DC power. In response to the determination at block 822, the controller may proceed along the control logic flow 800 to block 880. For example, at block 880, the controller can send a command/operation signal causing the attic fans 116, 118 to run at the low speed. In some examples, the controller can send a command/operation signal causing the attic fans 116, 118 to run at the upper limit of the low-speed range.
Returning to the discussion of block 814, in response to a determination at block 814 that the attic temperature does not satisfy the attic temperature threshold, the controller may proceed along the control logic flow 800 to block 816. In some embodiments, at block 816, the controller can determine whether the humidity level in the attic of the building is within predetermined parameters for operation of the ventilating system 100 such as described with reference to block 806. The logic of block 816 can be the same or similar to the logic of block 806 as described hereinabove. Thus, block 816 can correspond to block 806. The controller can perform block 816 in substantially the same manner as block 806. For example, at block 816, the controller may determine that the attic humidity level is not within operating parameters based on a determination that the attic humidity level value is less than a predetermined attic humidity level value. In some examples, at block 816, the controller can determine that the attic humidity level is within operating parameters based on a determination that the attic humidity level value is greater than a predetermined attic humidity level value.
At block 816, the predetermined attic humidity level value may be fixed or programmable. In some embodiments, the predetermined attic humidity operating parameter can be set and/or modified by the user utilizing a smartphone application and/or web application, or by the manufacturer or the system or the person installing the system or any combination of the foregoing. In some embodiments, at block 816, the predetermined attic humidity level value can be the predetermined attic humidity level value of block 806. In some embodiments, at block 816, the predetermined attic humidity level value can correspond to a predetermined humidity turn-on percentage. The predetermined humidity turn-on percentage can be 90%. The predetermined humidity turn-on percentage is not limited to 90%, but can be set to any humidity level parameter or value.
In response to a determination at block 816 that the attic humidity level is not within operating parameters, the controller may proceed along the control logic flow 800 to block 890. For example, at block 890, the controller can send a command/operation signal causing the attic fans 116, 118 to turn off.
In response to a determination at block 816 that the attic humidity level is within operating parameters, the controller may proceed along the control logic flow 800 to block 824. At block 824, in some embodiments, the controller can determine a speed at which to run attic fans 116, 118 based on a humidity speed. For example, a humidity speed may correspond to a high-speed humidity speed, a medium-speed humidity speed, or a low-speed humidity speed. In some embodiments, the humidity speed may be preset to the high-speed humidity speed, the medium-speed humidity speed, or the low-speed humidity speed. In some embodiments, the humidity speed may be preset by a user via, for example, device application 166 and/or web application.
In some embodiments, at block 824, the controller may optionally determine a speed at which to run attic fans 116, 118 based on the humidity level in the attic. In some embodiments, at block 824, the controller may determine the speed at which to run attic fans 116, 118 based on a comparison between the attic humidity level value and a predetermined attic humidity level value. In some embodiments, at block 824, the controller may implement a series of determinations such as according to multiple different predetermined attic humidity level values or ranges. For example, a first predetermined attic humidity level value may correspond to a high-speed humidity level value or range. In some examples, a second predetermined attic humidity level value may correspond to a medium-speed attic humidity level value or range. In some examples, a third predetermined attic humidity level value may correspond to a low-speed attic humidity level value or range.
In some embodiments, at block 824, the humidity speed and/or predetermined attic humidity level value(s) may be fixed or programmable. In some embodiments, the humidity speed and/or predetermined attic humidity level value(s) can be set and/or modified by the user utilizing a smartphone application and/or web application, or by the manufacturer or the system or the person installing the system or any combination of the foregoing. In some embodiments, at block 824, a high-speed humidity speed can correspond to a preset speed (e.g., set by a user) at which the controller causes attic fans 116, 118 to run at high speed (e.g., high RPM) such as described with reference to block 822. In some examples, a high-speed humidity level value can correspond to an attic humidity level value at which the controller causes attic fans 116, 118 to run at high speed. A high fan speed can include a range of speeds. In some embodiments, a high fan speed range can include a limit such as a lower and upper limit. For example, a high fan speed range can include a fan speed of about 800 RPM to about 950 RPM. In some embodiments, at block 824, a medium-speed humidity speed can correspond to a preset speed at which the controller causes attic fans 116, 118 to run at medium speed (e.g., medium RPM) such as described with reference to block 822. In some examples, a medium-speed humidity level value can correspond to an attic humidity level value at which the controller causes attic fans 116, 118 to run at medium speed. A medium fan speed can include a range of speeds. In some embodiments, a medium fan speed range can include a limit such as a lower and upper limit. For example, a medium fan speed range can include a fan speed of about 650 RPM to about 799 RPM. In some embodiments, at block 824, a low-speed humidity speed can correspond to a preset speed at which the controller causes attic fans 116, 118 to run at low speed (e.g., low RPM) such as described with reference to block 822. In some examples, a low-speed humidity level value can correspond to an attic humidity level value at which the controller causes attic fans 116, 118 to run at low speed. A low fan speed can include a range of speeds. In some embodiments, a low fan speed range can include a limit such as a lower and upper limit. For example, a low fan speed range can include a fan speed of about 500 RPM to about 649 RPM. In some embodiments, at block 824, there may be a humidity level value delta between low-, medium-, and high-speed humidity level values.
In some embodiments, the controller may determine that the humidity speed is set to a high speed (e.g., preset by a user to the high-speed humidity speed). In response to the determination at block 824, the controller may proceed along the control logic flow 800 to block 880. For example, at block 880, the controller can send a command/operation signal causing attic fans 116, 118 to run at a high speed such as described with reference to block 824 and/or block 822. In some examples, the controller can send a command/operation signal causing the attic fans 116, 118 to run at the upper limit of the high-speed range as described in block 824 and/or block 822.
In some embodiments, at block 824, the controller may determine that the humidity speed is set to a medium speed (e.g., preset by a user to the medium-speed humidity speed). In response to the determination at block 824, the controller may proceed along the control logic flow 800 to block 880. For example, at block 880, the controller can send a command/operation signal causing attic fans 116, 118 to run at a medium speed such as described with reference to lock 824 and/or block 822. In some examples, the controller can send a command/operation signal causing the attic fans 116, 118 to run at the upper limit of the medium-speed range as described in block 824 and/or block 822.
In some embodiments, at block 824 the controller may determine that the humidity speed is set to a low speed (e.g., preset by a user to the low-speed humidity speed). In response to the determination at block 824, the controller may proceed along the control logic flow 800 to block 880. For example, at block 880, the controller can send a command/operation signal causing attic fans 116, 118 to run at a low speed such as described with reference to block 824 and/or block 822. In some examples, the controller can send a command/operation signal causing the attic fans 116, 118 to run at the upper limit of the low-speed range as described in block 824 and/or block 822.
Returning to the discussion of block 808, in response to a determination at block 808 that the solar-generated DC voltage value satisfies the voltage threshold, the controller can proceed along the control logic flow 800 to block 812. At block 812, in some embodiments, the controller can determine whether the system 100 is in a daytime setting. A daytime setting can correspond to a mode of operating attic fans 116, 118 at times corresponding to when there is at least some DC voltage generated by the solar panel assembly. In some examples, the system 100 may be in the daytime setting when there is greater than 1 volt of solar-generated DC voltage. In some embodiments, the daytime setting can include at least three modes of operation. For example, a first mode of operation can correspond to a grid mode. In some examples, a second mode of operation can correspond to a solar mode. In some examples, a third mode of operation can correspond to a “grid and solar” mode.
In some embodiments, at block 812, the controller may determine that the system 100 is operating in a daytime setting corresponding to a grid mode. The grid mode can be the grid mode described with reference to block 810. In response to a determination at block 812 that the system 100 is operating in the grid mode, the controller may proceed along the control logic flow 800 to block 814 as described hereinabove.
In some embodiments, at block 812, the controller may determine that the system 100 is operating in a daytime setting corresponding to a solar mode. The solar mode can include operating attic fans 116, 118 based on voltage received from the solar panel assembly. For example, while in the solar mode, attic fans 116, 118 may run at a speed dictated by the DC voltage generated by the solar panel assembly. In some examples, while operating in the solar mode, attic fans 116, 118 may operate at the DC voltage generated by the solar panel assembly regardless of attic temperature. In response to the determination at block 812 that the system 100 is operating in the solar mode, the controller may proceed along the control logic flow 800 to block 820.
At block 820, in some embodiments, the controller can determine whether the temperature in the attic satisfies an attic temperature threshold such as described with reference to block 814. The logic of block 820 can be the same or similar to the logic of block 814 as described hereinabove. Thus, block 820 can correspond to block 814. The controller can perform block 820 in substantially the same manner as block 814. For example, at block 820, the controller may determine that the attic temperature threshold is not satisfied based on a determination that the attic temperature is less than a predetermined attic temperature value. In some examples, at block 820, the controller may determine that the attic temperature threshold is satisfied based on a determination that the attic temperature value is greater than a predetermined attic temperature value.
At block 820, the predetermined attic temperature value may be fixed or programmable. In some embodiments, the predetermined attic temperature value can be set and/or modified by the user utilizing a smartphone application and/or web application, or by the manufacturer or the system or the person installing the system or any combination of the foregoing. In some embodiments, at block 820, the predetermined attic temperature value can correspond to a low-speed temperature value. The low-speed temperature value can be the low-speed temperature value of block 814.
In response to a determination at block 820 that the attic temperature satisfies the attic temperature threshold, the controller may proceed along the control logic flow 800 to block 870. For example, at block 870, the controller can send a command/operation signal causing attic fans 116, 118 to run at a fan speed corresponding to the DC voltage generated by the solar panel assembly. In some examples, the fan speed may correspond to a low, medium, or high speed as described with reference to block 824 and/or block 822. In some examples, the fan speed may be less than or greater than the low, medium, and/or high speed as described in block 824 and/or block 822.
In response to a determination at block 820 that the attic temperature does not satisfy the attic temperature threshold, the controller may proceed along the control logic flow 800 to block 828. At block 828, in some embodiments, the controller can determine whether the humidity level in the attic of the building is within predetermined parameters for operation of the ventilating system 100 such as described with reference to block 816 and/or block 806. The logic of block 828 can be the same or similar to the logic of block 816 and/or block 806 as described hereinabove. Thus, block 828 can correspond to block 816 and/or block 806. The controller can perform block 828 in substantially the same manner as block 816 and/or block 806. For example, at block 828, the controller may determine that the attic humidity level is not within operating parameters based on a determination that the attic humidity level value is less than a predetermined attic humidity level value. In some examples, at block 828, the controller can determine that the attic humidity level is within operating parameters based on a determination that the attic humidity level value is greater than a predetermined attic humidity level value.
At block 828, the predetermined attic humidity level value may be fixed or programmable. In some embodiments, the predetermined attic humidity operating parameter can be set and/or modified by the user utilizing a smartphone application and/or web application, or by the manufacturer or the system or the person installing the system or any combination of the foregoing. In some embodiments, at block 828, the predetermined attic humidity level value can be the predetermined attic humidity level value of block 816 and/or block 806.
In response to a determination at block 828 that the attic humidity level is within predetermined parameters for operation of the system 100, the controller may proceed along the control logic flow 800 to block 870. For example, at block 870, the controller can send a command/operation signal causing attic fans 116, 118 to run at a fan speed corresponding to the DC voltage generated by the solar panel assembly. In some examples, the fan speed may correspond to a low, medium, or high speed as described with reference to block 824 or block 822. In some examples, the fan speed may be less than or greater than a low, medium, and/or high speed as described in block 824 or block 822.
In response to a determination at block 828 that the attic humidity level is not within parameters for operation of the system 100, the controller may proceed along the control logic flow 800 to block 890. For example, at block 890, the controller can send a command/operation signal causing the attic fans 116, 118 to turn off.
Returning to the discussion of block 812, in some embodiments, the controller may determine that the system 100 is operating in a daytime setting corresponding to a “grid and solar” mode. The “grid and solar” mode can include operating attic fans 116, 118 based on voltage received from the solar panel assembly and voltage received from the electrical utility power grid. For example, while in the “grid and solar” mode, attic fans 116, 118 can be supplied with the voltage generated by the solar panel assembly (e.g., all the voltage generated by the solar panel). In some examples, attic fans 116, 118 can be supplied with voltage from the solar panel assembly regardless of attic temperature. In some examples, if the attic temperature dictates a fan speed that requires more voltage than is provided by the solar panel assembly, the system 100 can supplement the voltage deficit with voltage from the electrical utility power grid. Supplementing the voltage deficit can include providing to attic fans 116, 118 the difference between DC voltage needed to run attic fans 116, 118 at a certain speed and DC voltage provided to attic fans 116, 118 by the solar panel assembly. Supplementing the voltage deficit can include providing attic fans 116, 118 with DC voltage from a voltage converter (e.g., voltage converter 170) that is connected to the electrical utility power grid. Supplementing the voltage deficit can include providing attic fans 116, 118 with DC voltage from a voltage regulator (e.g., voltage regulator 172) that receives converted DC voltage from the voltage converter. In response to a determination at block 812 that the system 100 is operating in the “grid and solar” mode, the controller may proceed along the control logic flow 800 to block 818. At block 818, in some embodiments, the controller can determine whether the system 100 is connected to AC power. For example, the controller can determine whether the voltage converter is connected to AC power of a building that is connected to an electrical utility power grid. In response to a determination at block 818 that the system 100 is not connected to AC power, the controller may proceed along the control logic flow 800 to block 820 as described hereinabove.
In response to a determination at block 818 that the system 100 is connected to AC power, the controller may proceed along the “AC Power Connected” flow path 826 of control logic flow 800. In

At block 830, the predetermined attic temperature value may be fixed or programmable. In some embodiments, the predetermined attic temperature value can be set and/or modified by the user utilizing a smartphone application and/or web application, or by the manufacturer or the system or the person installing the system or any combination of the foregoing. In some embodiments, at block 830, the predetermined attic temperature value can correspond to a low-speed temperature value. The low-speed temperature value can be the low-speed temperature value of block 820 and/or block 814.
In response to a determination at block 830 that the attic temperature satisfies the attic temperature threshold, the controller may proceed along control logic flow 800 to block 834. At block 834, in some embodiments, the controller can determine a speed at which to run attic fans 116, 118 based on the temperature in the attic such as described with reference to block 822. The logic of block 834 can be the same or similar to the logic of block 822 as described hereinabove. Thus, block 834 can correspond to block 822. The controller can perform block 834 in substantially the same manner as block 822. For example, the controller may determine the speed to which run attic fans 116, 118 based on a comparison between the attic temperature value and a predetermined attic temperature value. In some examples, the controller may implement a series of determinations such as according to multiple different predetermined attic temperature values or ranges. A first predetermined attic temperature value may correspond to a high-speed temperature value or range as described in block 822. A second predetermined attic temperature value may correspond to a medium-speed temperature value or range as described in block 822. A third predetermined attic temperature value may correspond to a low-speed temperature value or range such as the low-speed temperature value as described in block 822.
In some embodiments, at block 834, predetermined attic temperature value(s) may be fixed or programmable. In some embodiments, predetermined attic temperature value(s) can be set and/or modified by the user utilizing a smartphone application and/or web application, or by the manufacturer or the system or the person installing the system or any combination of the foregoing. In some embodiments, at block 834, a high-speed temperature value can correspond to an attic temperature value at which the controller causes attic fans 116, 118 to run at high speed (e.g., high RPM) such as described with reference to block 822. In some embodiments, a high fan speed can include a range of speeds. In some embodiments, a high fan speed range can include a limit such as a lower and upper limit. For example, a high fan speed range can include a fan speed of about 800 RPM to about 950 RPM. In some embodiments, at block 834, a medium-speed temperature value can correspond to an attic temperature value at which the controller causes attic fans 116, 118 to run at medium speed (e.g., medium RPM) such as described with reference to block 822. In some embodiments, a medium fan speed can include a range of speeds. In some embodiments, a medium fan speed range can include a limit such as a lower and upper limit. For example, a medium fan speed range can include a fan speed of about 650 RPM to about 799 RPM. In some embodiments, at block 834, a low-speed temperature value can correspond to an attic temperature value at which the controller causes attic fans 116, 118 to run at low speed (e.g., low RPM) as described with reference to block 822. In some embodiments, a low fan speed can include a range of speeds. In some embodiments, a low fan speed range can include a limit such as a lower and upper limit. For example, a low fan speed range can include a fan speed of about 500 RPM to about 649 RPM. In some embodiments, at block 834, there may be a five-degree temperature delta between low-, medium-, and high-speed temperature values.
In response to a determination at block 834 of a speed at which to run attic fans 116, 118, the controller may proceed along the control logic flow 800 to block 836. At block 836, in some embodiments, the controller can determine whether the solar panel voltage satisfies a voltage threshold. The solar panel voltage can correspond to DC output voltage generated by the solar panel assembly. The controller can monitor the solar-generated DC voltage level and receive a value corresponding to the solar-generated DC voltage level. In some embodiments, the controller can determine whether the solar-generated DC voltage level satisfies the voltage threshold based on a comparison between the solar-generated DC voltage level value and a predetermined voltage level value such as described with reference to block 808. In some embodiments, at block 836, the controller may implement a series of determinations such as according to multiple different voltage thresholds. In some embodiments, the controller may determine that a first voltage threshold is satisfied based on a comparison between the solar-generated DC voltage level value and a first predetermined voltage level value. In some embodiments, at block 836, the controller may determine that a second voltage threshold is satisfied based on a comparison between the solar-generated DC voltage level value and a second predetermined voltage level value. In some embodiments, the controller may determine that a third voltage threshold is satisfied based on a comparison between the solar-generated DC voltage level value and a third predetermined voltage level value.
At block 836, predetermined voltage level value(s) may be fixed or programmable. In some embodiments, predetermined voltage level(s) can be set and/or modified by the user utilizing a smartphone application and/or web application, or by the manufacturer or the system or the person installing the system or any combination of the foregoing. In some embodiments, predetermined voltage level value(s) can be the predetermined voltage level value of block 808 as described hereinabove. In some embodiments, the first predetermined voltage level value can be 22 volts. The first predetermined voltage level value is not limited to 22 volts, but can be set to any voltage value. In some embodiments, the second predetermined voltage level value can be 13 volts. The second predetermined voltage level value is not limited to 13 volts, but can be set to any voltage value. In some embodiments, the third predetermined voltage level value can be 11 volts. The third predetermined voltage level value is not limited to 11 volts, but can be set to any voltage value.
In some embodiments, at block 836, predetermined voltage level value(s) can be associated with predetermined attic temperature value(s) of block 834. For example, at block 836, the first predetermined voltage level value may be associated with the first predetermined attic temperature value of block 834. In some embodiments, the first predetermined attic temperature value of block 834 can be the high-speed temperature value of block 822. In some examples, at block 836, the second voltage threshold may be associated with the second predetermined attic temperature value of block 834. In some embodiments, the second predetermined attic temperature value of block 834 can be the medium-speed temperature value of block 822. In some examples, at block 836, the third voltage threshold may be associated with the third predetermined attic temperature value of block 834. In some embodiments, the third predetermined attic temperature value of block 834 can be the low-speed temperature value of block 822.
In response to a determination at block 834 to run attic fans 116, 118 at a high fan speed (e.g., the controller determines that the attic temperature is greater than the first predetermined attic temperature value), at block 836, the controller can determine whether the solar panel voltage satisfies the first voltage threshold. For example, the controller may determine that the first voltage threshold is satisfied based on a determination that the solar-generated DC voltage level value is at or greater than the first predetermined voltage level value. In some examples, the controller may determine that the first voltage threshold is not satisfied based on a determination that the solar-generated DC voltage value is less than the first predetermined voltage level value. In response to a determination at block 836 that the solar panel voltage satisfies the first voltage threshold (e.g., solar-generated DC voltage is at or greater than 22 volts), the controller may proceed along control logic flow 800 to block 870. For example, at block 870, the controller can send a command/operation signal causing attic fans 116, 118 to run at a fan speed corresponding to the DC voltage generated by the solar panel assembly. The fan speed may correspond to a high speed as described with reference to block 834 and/or block 822. In some examples, at block 870, the controller may send a command/operation signal causing attic fans 116, 118 to run at a fan speed corresponding to the DC voltage generated by the solar panel assembly even though the voltage provided by the solar panel assembly is greater than the voltage needed to run attic fans 116, 118 at the high speed as described in block 834 and/or block 822. The fan speed may be greater than the high speed.
In response to a determination at block 836 that the first voltage threshold is not satisfied (e.g., solar-generated DC voltage is less than 22 volts), the controller may proceed along the control logic flow 800 to block 840.
In response to a determination at block 834 to run attic fans 116, 118 at a medium fan speed (e.g., the controller determines that the attic temperature is less than the first predetermined attic temperature value and greater than the second predetermined attic temperature value), at block 836, the controller can determine whether the solar panel voltage satisfies a second voltage threshold. For example, the controller may determine that the second voltage threshold is satisfied based on a determination that the solar-generated DC voltage level value is at or greater than the second predetermined voltage level value. In some examples, the controller may determine that the second voltage threshold is not satisfied based on a determination that the solar-generated DC voltage value is less than the second predetermined voltage level value. In response to a determination at block 836 that the solar panel voltage satisfies the second voltage threshold (e.g., solar-generated DC voltage is at or greater than 13 volts), the controller may proceed along control logic flow 800 to block 870. For example, at block 870, the controller can send a command/operation signal causing attic fans 116, 118 to run at a fan speed corresponding to the DC voltage generated by the solar panel assembly. In some examples, the fan speed may correspond to a medium speed as described with reference to block 834 or block 822.

For example, the controller may determine that the third voltage threshold is satisfied based on a determination that the solar-generated DC voltage level value is at or greater than the third predetermined voltage level value. In some examples, the controller may determine that the third voltage threshold is not satisfied based on a determination that the solar-generated DC voltage value is less than the third predetermined voltage level value. In response to a determination at block 836 that the solar panel voltage satisfies the third voltage threshold (e.g., solar-generated DC voltage is at or greater than 11 volts), the controller may proceed along control logic flow 800 to block 870. For example, at block 870, the controller can send a command/operation signal causing attic fans 116, 118 to run at a fan speed corresponding to the DC voltage generated by the solar panel assembly. In some examples, the fan speed may correspond to a low speed as described with reference to block 834 or block 822. In some examples, at block 870, the controller may send a command/operation signal causing attic fans 116, 118 to run at a fan speed corresponding to the DC voltage generated by the solar panel assembly even though the voltage provided by the solar panel assembly is greater than the voltage needed to run attic fans 116, 118 at the low speed as described in block 834 and/or block 822. The fan speed may be greater than the low speed.
In response to a determination at block 836 that the third voltage threshold is not satisfied (e.g., solar-generated DC voltage is less than 11 volts), the controller may proceed along the control logic flow 800 to block 840.
At block 840, in some embodiments, the controller can supplement DC voltage supplied to attic fans 116, 118 by the solar panel assembly with voltage from the electrical utility power grid such as described with reference to block 812. The controller can determine an amount of DC voltage by which to supplement the DC voltage generated by the solar panel assembly by determining a difference between predetermined voltage level values(s) and the solar-generated DC voltage level value.
At block 840, predetermined voltage level value(s) may be fixed or programmable. In some embodiments, predetermined voltage level(s) can be set and/or modified by the user utilizing a smartphone application and/or web application, or by the manufacturer or the system or the person installing the system or any combination of the foregoing. In some embodiments, predetermined voltage level value(s) can be the predetermined voltage level value described in block 808 as described hereinabove. In some embodiments, predetermined voltage level value(s) can be the predetermined voltage level value(s) described in block 836. For example, the first predetermined voltage level value can be 22 volts. The first predetermined voltage level value is not limited to 22 volts, but can be set to any voltage value. In some examples, the second predetermined voltage level value can be 13 volts. The second predetermined voltage level value is not limited to 13 volts, but can be set to any voltage value. In some examples, the third predetermined voltage level value can be 11 volts. The third predetermined voltage level value is not limited to 11 volts, but can be set to any voltage value. In some embodiments, at block 840, predetermined voltage value(s) may correspond to DC voltage required to run attic fans 116, 118 at various different speeds such as high, medium, low, or any other speed.
In some embodiments, in response to a determination at block 836 that the first voltage threshold is not satisfied, at block 840, the controller can supplement attic fans 116, 118 with voltage from the electrical power utility grid. For example, the controller can determine a first difference between the first predetermined voltage level value and the solar-generated DC voltage level value. The first determined voltage difference can correspond to additional voltage provided to attic fans 116, 118 from the electrical utility power grid and required to run attic fans 116, 118 at a high speed. The high speed can be any speed within the high-speed range described with reference to block 834 and/or block 822. The first determined voltage difference may correspond to additional voltage required to run attic fans 116, 118 at the upper limit of the high-speed range as described with reference to block 834 and/or block 822. In some examples, at block 836, the controller may determine that 22 volts of DC voltage are needed to run attic fans 116, 118 at the high speed. The controller may determine the first voltage difference by determining the difference between the 22 volts required to run attic fans 116, 118 at the high speed and the solar-generated DC voltage. The controller may perform the following calculation: X=22 volts−solar-generated DC voltage. Reference “X” indicates the amount of DC voltage to be supplemented from the electrical power utility grid and provided to attic fans 116, 118 to run at the high speed. Reference “X” can be the first determined voltage difference. The controller can supplement voltage supplied to attic fans 116, 118 by the solar panel assembly with the first determined voltage difference and proceed along the control logic flow 800 to block 880. For example, at block 880, the controller can send a command/operation signal causing the attic fans 116, 118 to run at the high speed. The controller may send a control signal to the voltage regulator that receives converted DC voltage from the voltage converter and cause the voltage regulator to provide attic fans 116, 118 with X volts of DC voltage. In some examples, the controller can send a command/operation signal causing the attic fans 116, 118 to run at the upper limit of the high-speed range as described in block 834 and/or block 822.
In some embodiments, in response to a determination at block 836 that the second voltage threshold is not satisfied, at block 840, the controller can determine a second difference between the second predetermined voltage level value and the solar-generated DC voltage level value. The second determined voltage difference can correspond to additional voltage provided to attic fans 116, 118 from the electrical utility power grid and required to run attic fans 116, 118 at a medium speed. The medium speed can be any speed within the medium-speed range described with reference to block 834 and/or block 822. The second determined voltage difference can correspond to additional voltage required to run attic fans 116, 118 at the upper limit of the medium-speed range as described with reference to block 834 and/or block 822. In some examples, at block 836, the controller may determine that 13 volts of DC voltage are needed to run attic fans 116, 118 at the medium speed. The controller may determine the second voltage difference by determining the difference between the 13 volts required to run attic fans 116, 118 at the medium speed and the solar-generated DC voltage. The controller may perform the following calculation: X=13 volts−solar-generated DC voltage. Reference “X” indicates the amount of DC voltage to be supplemented from the electrical power utility grid and provided to attic fans 116, 118 to run at the medium speed. Reference “X” can be the second determined voltage difference. The controller can supplement voltage supplied to attic fans 116, 118 by the solar panel assembly with the second determined voltage difference and proceed along the control logic flow 800 to block 880. For example, at block 880, the controller can send a command/operation signal causing the attic fans 116, 118 to run at the medium speed. The controller may send a control signal to the voltage regulator that receives converted DC voltage from the voltage converter and cause the voltage regulator to provide attic fans 116, 118 with X volts of DC voltage. In some examples, the controller can send a command/operation signal causing the attic fans 116, 118 to run at the upper limit of the medium-speed range as described in block 834 and/or block 822.
In some embodiments, in response to a determination at block 836 that the third voltage threshold is not satisfied, at block 840, the controller can determine a third difference between the third predetermined voltage level value and the solar-generated DC voltage level value. The third determined voltage difference can correspond to additional voltage provided to attic fans 116, 118 from the electrical utility power grid and required to run attic fans 116, 118 at a low speed. The low speed can be any speed within the low-speed range described with reference to block 834 and/or block 822. The third determined voltage difference can correspond to additional voltage required to run attic fans 116, 118 at the upper limit of the low-speed range as described with reference to block 834 and/or block 822. In some examples, at block 836, the controller may determine that 11 volts of DC voltage are needed to run attic fans 116, 118 at the low speed. The controller may determine the third voltage difference by determining the difference between the 11 volts required to run attic fans 116, 118 at the low speed and the solar-generated DC voltage. The controller may perform the following calculation: X=11 volts−solar-generated DC voltage. Reference “X” indicates the amount of DC voltage to be supplemented from the electrical power utility grid and provided to attic fans 116, 118 to run at the low speed. Reference “X” can be the third determined voltage difference. The controller can supplement voltage supplied to attic fans 116, 118 by the solar panel assembly with the third determined voltage difference and proceed along the control logic flow 800 to block 880. For example, at block 880, the controller can send a command/operation signal causing the attic fans 116, 118 to run at the low speed. The controller may send a control signal to the voltage regulator that receives converted DC voltage from the voltage converter and cause the voltage regulator to provide attic fans 116, 118 with X volts of DC voltage. In some examples, the controller can send a command/operation signal causing the attic fans 116, 118 to run at the upper limit of the low-speed range as described in block 834 and/or block 822.
Returning to the discussion of block 830, in response to a determination at block 830 that the attic temperature does not satisfy the attic temperature threshold, the controller may proceed along the control logic flow 800 to block 832. At block 832, in some embodiments, the controller can determine whether the humidity level in the attic of the building is within predetermined parameters for operation of the ventilating system 100 such as described with reference to block 828, block 816, and/or block 806. The logic of block 832 can be the same or similar to the logic of block 828, block 816, and/or block 806 as described hereinabove. Thus, block 832 can correspond to block 828, block 816, and/or block 806. The controller can perform block 832 in substantially the same manner as block 828, block 816, and/or block 806. For example, at block 832, the controller may determine that the attic humidity level is not within operating parameters based on a determination that the attic humidity level value is less than a predetermined attic humidity level value. In some examples, at block 832, the controller can determine that the attic humidity level is within operating parameters based on a determination that the attic humidity level value is greater than a predetermined attic humidity level value.
At block 832, the predetermined attic humidity level value may be fixed or programmable. In some embodiments, the predetermined attic humidity operating parameter can be set and/or modified by the user utilizing a smartphone application and/or web application, or by the manufacturer or the system or the person installing the system or any combination of the foregoing. In some embodiments, at block 832, the predetermined attic humidity level value can be the predetermined attic humidity level value of block 828, block 816, and/or block 806.
In response to a determination at block 832 that the attic humidity level is not within predetermined parameters for operation of the system 100, the controller may proceed along control logic flow 800 to block 890. For example, at block 890, the controller can send a command/operation signal causing the attic fans 116, 118 to turn off.
In response to a determination at block 832 that the attic humidity level is within predetermined parameters for operation of the system 100, the controller may proceed along control logic flow 800 to block 838. At block 838, in some embodiments, the controller can determine a speed at which to run attic fans 116, 118 based on a humidity speed such as described with reference to block 824. For example, a humidity speed may correspond to a high-speed humidity speed, a medium-speed humidity speed, or a low-speed humidity speed. In some embodiments, the humidity speed may be preset to the high-speed humidity speed, the medium-speed humidity speed, or the low-speed humidity speed. In some embodiments, the humidity speed may be preset by a user via, for example, device application 166 and/or web application. In some embodiments, at block 838, the controller may optionally determine a speed at which to run attic fans 116, 118 based on a humidity level in the attic such as described with reference to block 824. For example, the controller may determine the speed at which to run attic fans 116, 118 based on a comparison between the attic humidity level value and a predetermined attic humidity level value. In some embodiments, at block 838, the controller may implement a series of determinations such as according to multiple different predetermined attic humidity level values or ranges. A a first predetermined attic humidity level value may correspond to a high-speed humidity level value or range. A second predetermined attic humidity level value may correspond to a medium-speed attic humidity level value or range. A third predetermined attic humidity level value may correspond to a low-speed attic humidity level value or range.

In some examples, a high-speed humidity level value can correspond to an attic humidity level value at which the controller causes attic fans 116, 118 to run at high speed. A high fan speed can include a range of speeds. In some embodiments, a high fan speed range can include a limit such as a lower and upper limit. For example, a high fan speed range can include a fan speed of about 800 RPM to about 950 RPM. In some embodiments, at block 824, a medium-speed humidity speed can correspond to a preset speed at which the controller causes attic fans 116, 118 to run at medium speed (e.g., medium RPM) such as described with reference to block 822. In some examples, a medium-speed humidity level value can correspond to an attic humidity level value at which the controller causes attic fans 116, 118 to run at medium speed. A medium fan speed can include a range of speeds. In some embodiments, a medium fan speed range can include a limit such as a lower and upper limit. For example, a medium fan speed range can include a fan speed of about 650 RPM to about 799 RPM. In some embodiments, at block 824, a low-speed humidity speed can correspond to a preset speed at which the controller causes attic fans 116, 118 to run at low speed (e.g., low RPM) such as described with reference to block 822. In some examples, a low-speed humidity level value can correspond to an attic humidity level value at which the controller causes attic fans 116, 118 to run at low speed. A low fan speed can include a range of speeds. In some embodiments, a low fan speed range can include a limit such as a lower and upper limit. For example, a low fan speed range can include a fan speed of about 500 RPM to about 649 RPM. In some embodiments, at block 838, there may be a humidity level value delta between low-, medium-, and high-speed humidity level values.
At block 838, in some embodiments, humidity speed(s) may be associated with voltage threshold(s) of block 836 as described herein. For example, a humidity speed corresponding to a high-speed humidity speed may be associated with the first voltage threshold of block 836. In some examples, a humidity speed corresponding to a medium-speed humidity speed may be associated with the second voltage threshold of block 836. In some examples, a humidity speed corresponding to a low-speed humidity speed may be associated with the third voltage threshold of block 836.

The described functionality can be implemented in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the disclosure.
Moreover, the various illustrative logical blocks, user interfaces, and modules described in connection with the embodiments disclosed herein can be implemented or performed by a machine, such as a general purpose processor device, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A processor device can be a microprocessor, but in the alternative, the processor device can be a controller, microcontroller, or state machine, combinations of the same, or the like. A processor device can include electrical circuitry configured to process computer-executable instructions. In another embodiment, a processor device includes an FPGA or other programmable device that performs logic operations without processing computer-executable instructions. A processor device can also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration. Although described herein primarily with respect to digital technology, a processor device may also include primarily analog components. For example, some or all of the algorithms described herein may be implemented in analog circuitry or mixed analog and digital circuitry. A computing environment can include any type of computer system, including, but not limited to, a computer system based on a microprocessor, a mainframe computer, a digital signal processor, a portable computing device, a device controller, or a computational engine within an appliance, to name a few.
The elements of a method, process, routine, or algorithm described in connection with the embodiments disclosed herein can be embodied directly in hardware, in a software module executed by a processor device (controller), or in a combination of the two, that command, control, or cause the system(s) and associated components described herein to perform one or more functions or features of the method, process, routine, or algorithm. A software module can reside in RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, a removable disk, a CD-ROM, or any other form of a non-transitory computer-readable storage medium. An exemplary storage medium can be coupled to the processor device such that the processor device can read information from, and write information to, the storage medium. In the alternative, the storage medium can be integral to the processor device. The processor device and the storage medium can reside in an ASIC. The ASIC can reside in a user terminal. In the alternative, the processor device and the storage medium can reside as discrete components in a user terminal.
