This disclosure generally relates to HVAC controllers for controlling HVAC systems, and more particularly, to HVAC control systems that include an HVAC remote control unit.
Heating, ventilation, and/or air conditioning (HVAC) systems are often used to control the comfort level within a building or other structure. Many HVAC controllers include a controller that activates and deactivates one or more HVAC components of the HVAC system to affect and control one or more environmental conditions within the building. These environmental conditions can include, but are not limited to, temperature, humidity, and/or ventilation.
In some but not all cases, the HVAC controllers are embodied in a thermostat that is mounted to a wall or the like within a building. A typical thermostat includes a local temperature sensor, and/or in some cases, accesses other sensors such as one or more remote temperature sensors. The sensors are used to sense one or more environmental conditions of the inside space, and provide a measure of the sensed environmental condition to the HVAC controller. The HVAC controller may use the measure provided by the sensor to control the one or more HVAC components to achieve desired programmed or set environmental conditions. In many cases, the sensors are provided within the housing of the HVAC controller itself, which is typically mounted at or near the walls of the building, and/or the sensors are mounted at particular fixed locations within the building, which are also typically located at or near the walls of the building. In some cases, the environmental conditions at or near the walls of the building can be different from the environmental conditions away from the walls. As such, the environmental conditions sensed by the sensors sometimes do not accurately represent the actual environmental conditions felt by the occupants of the building.
HVAC controllers often have a user interface that can be used to program or otherwise operate the HVAC controller. By interacting with the user interface, the user may, for example, change a set point, program a schedule, enable or disable certain HVAC components, and/or perform some other action or tasks. In order to interact with the user interface, the user must typically physically walk over to the HVAC controller. In zoned systems, which typically include a plurality of HVAC controllers, the user must typically often walk over and interact with each HVAC controller where changes are desired.
This disclosure generally relates to HVAC controllers for controlling HVAC systems, and more particularly, to HVAC control systems that include an HVAC remote control unit. In some instances, an HVAC remote control unit is provided that wirelessly communicates with one or more HVAC controllers and/or other HVAC devices. In some cases, the HVAC remote controller may be configured to automatically determine whether the HVAC system is a zoned HVAC system or a non-zoned HVAC system. The HVAC remote controller may be configured to select from one or more menu screens for displaying on a display and/or to automatically change its behavior depending on whether the HVAC system is a zoned HVAC system or a non-zoned HVAC system. In some cases, when HVAC system includes one or more wireless thermostats, the HVAC remote controller may be configured to detect each of the one or more wireless thermostats of the HVAC system via a wireless interface, and to automatically change its behavior depending on whether only one wireless thermostat is detected or whether two or more wireless thermostats are detected.
The preceding summary is provided to facilitate a general understanding of some of the innovative features unique to the present disclosure and is not intended to be a full description. A full appreciation of the disclosure can be gained by taking the entire specification, claims, drawings, and abstract as a whole.
The invention may be more completely understood in consideration of the following detailed description of various illustrative embodiments of the invention in connection with the accompanying drawings, in which:
The following description should be read with reference to the drawings wherein like reference numerals indicate like elements throughout the several views. The detailed description and drawings show several embodiments which are meant to be illustrative of the claimed invention.
In the illustrative HVAC system shown in
In some cases, the system of vents or ductwork 4 and 6 can include one or more dampers 11 to regulate the flow of air. For example, one or more dampers 11 may be coupled to one or more of the HVAC controllers 8 and can be coordinated with the operation of one or more HVAC components 2. The one or more HVAC controllers 8 may actuate dampers 11 to an open position, a closed position, and/or a partially open position to modulate the flow of air from the one or more HVAC components 2 to an appropriate room and/or zone in the building or other structure. The dampers 11 may be particularly useful in zoned HVAC systems, and may be used to control which zone(s) receives conditioned air from the HVAC components 2.
It is contemplated that the one or more HVAC controllers 8 may be configured to control the comfort level of the building or structure by activating and deactivating the one or more HVAC components 2. In some cases, the one or more HVAC controllers 8 may be thermostats, such as, for example, wall mountable thermostat, but this is not required in all embodiments. In some embodiments, the HVAC controllers 8 may be zone controllers, each controlling the comfort level within a particular zone in the building or other structure. Some contemplated HVAC controllers include that disclosed in U.S. Provisional Patent Application Ser. No. 60/991,626, titled “HVAC CONTROLLER”, the entirety of which is incorporated herein by reference.
As shown in
In a zoned HVAC system, there may be more than one HVAC controller 8 (or zone controllers), each controlling a corresponding zone within the building or other structure. When so provided, it is contemplated that the HVAC remote controller 10 may be operatively coupled to each of the HVAC controllers 8, either simultaneously, sequentially or by user selection. In some cases, the HVAC remote controller 10 may be configured to automatically or manually detect the number of zoned HVAC controllers 8 in the zoned HVAC system. For example, the HVAC remote controller 10 may be configured to automatically detect and establish communication with each of the zoned HVAC controllers 8, either simultaneously, sequentially or by user selection. Once connected, the HVAC remote controller 10 may be used to provide remote temperature sensing and/or parameter or setting control for the corresponding zoned HVAC controller 8. In some cases, the HVAC remote controller 10 may dynamically change its behavior based on whether it detects a non-zoned or a zone system. For example, when a zoned system is detected, the HVAC remote controller 10 may automatically provide a selection mechanism on the user interface of the HVAC remote controller 10 that allows a user to select, display and/or control parameters and/or settings of an HVAC controller 8 that corresponds to a selected zone in the building or other structure. When a non-zoned system is detected, the zone selection mechanism may not be provided on the display.
Rather than establishing communication with the HVAC controllers 8, and then have the HVAC controllers 8 issue commands or calls to the HVAC components 2, it is contemplated that the HVAC remote controller 10 may issue commands or calls directly to the HVAC components 2, typically across a wireless interface.
Control module 12 of HVAC remote controller 10 may be configured to help control the comfort level (i.e. heating, cooling, ventilation, air quality, etc.) of at least a portion of the building or structure by controlling whether one or more HVAC components 2 of HVAC equipment are activated. In some instances, control module 12 may include a processor 20 and a memory 22. Control module 12 may be configured to control and/or set one or more HVAC functions, such as, for example, HVAC schedules, temperature setpoints, humidity setpoints, trend logs, timers, environment sensing, and/or other HVAC functions or programs, as desired. In some cases, control module 12 may be configured to remotely configure the one or more settings of the HVAC controller, such as, for example, HVAC controller schedules, temperature setpoints, humidity setpoints, trend logs, timers, environment sensing, HVAC controller programs, user preferences, and/or other HVAC controller settings, as desired. In the illustrative embodiment, control module 12 may help control the comfort level of at least a portion of the building or structure using the temperature sensed by temperature sensor of the one or more sensors 18, when provided.
Memory 22 may be used to store any desired information, such as the aforementioned HVAC schedules, temperature setpoints, humidity setpoints, trend logs, timers, environmental settings, and any other settings and/or information as desired. Control module 12 may store information within memory 22 and may subsequently retrieve the stored information. Memory 22 may include any suitable type of memory, such as, for example, random-access memory (RAM), read-only member (ROM), electrically erasable programmable read-only memory (EEPROM), Flash memory, or any other suitable memory, as desired.
Wireless interface 14 of the HVAC remote controller 10 may be configured to wirelessly communicate (i.e. transmit and/or receive signals) with a wireless interface of one or more HVAC controllers 8 (and/or HVAC components 2). For example, wireless interface 14 may be configured to communicate with a wireless interface of HVAC controllers 8 (see
User interface 14 may be any suitable interface that is configured to display and/or solicit information as well as permit a user to enter data and/or other settings, as desired. In some cases, user interface 16 of the HVAC remote controller 10 may allow a user or technician to program and/or modify one or more control parameters of HVAC remote controller 10, such as programming, set point, time, equipment status and/or parameters, as desired. Alternatively, or in addition, user interface 16 may allow a user or technician to program and/or modify one or more control parameters of the HVAC controller 8. In some instances, the user interface 16 may include a touch screen, a liquid crystal display (LCD) panel and keypad, a dot matrix display, a computer, buttons and/or any other suitable interface, as desired. In one illustrative embodiment, at least some of the parameters and/or settings may be transmitted to a HVAC controller 8 via wireless interface 14.
The HVAC remote controller 24 may be configured to provide substantial display and/or programming functionality.
In some instances, the home screen may allow many or all of the user settings of the HVAC remote controller 24 to be viewed and controlled, without having to access sub-menus. In one illustrative embodiment, all settings (other than installer setup settings) may be accessed and controlled in a single menu level or screen (e.g. the home screen). These settings may include, for example, system setting (e.g. heat, cool, off), set point(s), zone selection, clock, indoor temperature, outdoor temperature, etc. It is contemplated that this may be accomplished even when the display 42 is a fixed segment LCD display. In one example, a HVAC remote controller may display a home screen that can be used to change an HVAC system setting (e.g. heat, cool, off), a set point temperature, and a hold setting without having to access a sub-menu. The example home screen may also allow a user to: change whether the HVAC system uses a temperature sensed by the HVAC remote control unit or a separate thermostat; select between two or more zones when the HVAC system is a zoned HVAC system; and/or display one or more temperature readings (e.g. indoor temperature reading and/or outdoor temperature reading), without having to access a sub-menu. In some cases, less used settings, such as installer setup settings, may be provided in one or more sub-menus or other menus, if desired. In other embodiments, at least some of the settings for the main user functionality of the HVAC remote controller 24 may also be incorporated into one or more sub-menus, if desired.
In the illustrative embodiment, touch screen display 42 may be configured to have a screen 30 that provides the user with information about the operational status of the HVAC controller 8 and/or HVAC remote controller 24. This information may include, for example, the current inside temperature 48, the current outside temperature 46, the current time 44, the current heat and/or cool set point 50, as well as other operational parameters and/or information as desired. By pressing various icon buttons on the touch screen display 42, the HVAC remote controller 24 can be configured to access and/or modify various operational settings of the HVAC controller 8 and/or HVAC remote controller 24. For example, the user may use the touch screen display 42 to adjust the current temperature or humidity setpoints, change the clock or date settings of the HVAC controller 8 and/or HVAC remote controller 24, change the operational status of the HVAC controller 8 and/or HVAC remote controller 24 (i.e. heat 32, cool 34, off 36), etc.
Although not expressly shown, in some cases, the touch screen display 42 may be configured to display the humidity level on a portion of screen 30. In this case, touch screen display 42 may be configured to display the outdoor humidity level and/or indoor humidity level, as desired. In one example, touch screen display 42 may be configured to display the outdoor humidity level when the user touches the touch screen display adjacent to the current outside temperature 46. In another example, touch screen display 42 may be configured to display the inside humidity level when the user touches the touch screen display adjacent to the current inside temperature 48. In some cases, the inside and/or outside humidity levels may be displayed for a period of time or, in other cases, may be displayed until the user touches the touch screen display 42 adjacent to the current inside temperature 48 and/or the current outside temperature 42, respectively. However, it is contemplated that any suitable method of displaying the outside and/or inside humidity levels may be used, as desired.
The touch screen display 42 may indicate and/or allow a user to set which temperature sensor (e.g. temperature sensor of the HVAC remote controller 10 of
As illustrated, the touch screen display 42 may simultaneously display an icon for each option that a user may wish to select. For example, touch screen display 42 may include icons 32, 34, and 36, corresponding to the heat mode, cool mode, and off mode, respectively, of the HVAC controller 8, and icons 38 and 40 for indicating which device's sensed temperature (e.g. the HVAC controller 8 or the HVAC remote controller 10), respectively, is currently being used to control the comfort level of the building or other structure. To indicate which option is currently selected, the icon corresponding to the selected option may include a bold outline, as illustrated by bold outline around icon 38 and icon 32, and/or a dot or other marker provided within or proximate the outline of the icon, as illustrated by the dot in the relative top left corner of icon 38 and icon 32. It is contemplated that the option that is currently selected may include a different border, be highlighted, grayed out, or otherwise indicated in any suitable visually discernable manner, as desired. In some cases, a user may be able to touch the area of the touch screen display 42 that corresponds to icon 32, 34, or 36 to manually select and switch the operation status of the HVAC controller 8, or the area of touch screen display 42 corresponding to icon 38 or 40 to manually select and switch which device's sensed temperature is currently being used to control the comfort level within the building or other structure.
In some embodiments, HVAC remote controller 24 may include a backlight operation to illuminate at least a portion of touch screen display 42. In some cases, the backlight may be configured to illuminate touch screen display 42 when the user touches a portion of the touch screen display 42. In one example, the backlight may be configured to illuminate the touch screen display 42 for a period of time, such as, for example, one second, two seconds, three seconds, four seconds, five seconds, ten seconds, or any other suitable period of time, as desired. In this case, the period of time may be reset each time the user touches the touch screen display 42. Additionally, the illustrative HVAC remote controller 24 may include one or more backlight operation settings, such as, for example, the brightness, the length of time to illuminate the touch screen display 42 after a touch, and/or any other suitable backlight setting, as desired.
In some cases, the HVAC remote controller 24 may be configured to activate the backlight to illuminate the touch screen display 42 when the user touches any portion of the touch screen display 42. However, in other cases, the HVAC remote controller 24 may be configured to illuminate the touch screen display 42 only when a predetermined portion of the touch screen display 42 is touched, such as, for example, the corners of the touch screen display 42, a portion of the touch screen display 42 that does not correspond to any icon, or any other suitable portion, as desired. In another illustrative case, the HVAC remote controller 24 may be configured to include a button to activate and/or deactivate the backlight display on the housing 28 of the HVAC remote controller 24, but this is not required.
In one example, the touch screen display 42 may be configured to illuminate the backlight when the user touches the touch screen display 42. When the touch screen display 42 is illuminated, the user may then be able to view, control, and/or adjust the one or more parameters of the HVAC remote controller 24. In this example, the HVAC remote controller 24 may be configured to prevent any parameter or setting changes to the HVAC remote controller 24 when the touch screen display 42 is not illuminated by the backlight, but this is not required.
In
In the illustrative embodiment, the set point shown as the current heat and/or cool set point 50 may be changed by touching the region of the touch screen display 42 that corresponds to the up arrow and/or the down arrow shown above and below the heat and/or cool set point 50. If the set point is changed, the touch screen display 42 may display, for example, screen 92 shown in
In some cases, the illustrative HVAC remote controller 24 may be configured to include an auto operational mode. In one example, the auto mode may be set, or switched to, by touching the touch screen display 42 corresponding to both icon 32 and icon 34 simultaneously. In some cases, the touch may have to last for a period of time, but this is not required. If the operational mode is switched to auto mode, the touch screen display 42 may display screen 142 shown in
In some cases, the HVAC remote controller 24 may be configured to detect a power level, such as, for example, a remaining battery power level. If the remaining battery power level detected by the HVAC remote controller 24 is less than a threshold level, in some cases, the touch screen display 42 may display screen 76 or 80 shown in
In the illustrative embodiment, the HVAC remote controller may be configured to wirelessly communication with one or more HVAC controllers 8 and/or HVAC components 2. In some cases, it is contemplated that the wireless communication signal, such as, for example, a radio frequency (RF) signal, may be lost at least temporarily. In this case, when the communication signal is lost, the touch screen display 42 may display screen 174 and/or 178 of
Screen 56 provides parameters related to HVAC operational status including, for example, the current inside temperature 48, the current outside temperature 46, the current time 44, and the current heat and/or cool set point 50. In addition, screen 56 may provide the operational status of the HVAC control system. As illustrated, touch screen display 42 may include an icon 32 for indicating when the HVAC controller is in heat mode, an icon 34 for indicating when the HVAC controller is in cool mode, and an icon 36 for indicating when the HVAC control is off. As described above, to indicate the current operational status, the icon that corresponds to the current operational status of the HVAC system may include a bold outline, as illustrated by bold outline around icon 32, and/or a dot within the icon, or may include a different border, may be highlighted, grayed out, or otherwise differentiated from the other operational status icons. In some cases, a user may be able to touch the area of the touch screen display 42 corresponding to icon 32, 34, or 36 to manually switch the operational status of the HVAC system. Although not expressly shown, it is contemplated that screen 56 may include an indication of which device (e.g. which temperature sensor is currently being used to control the comfort level of the building or other structure) is controlling the HVAC controller, if desired.
In the illustrative embodiment, screen 56 may include an HVAC zone navigation area 58 for indicating and/or navigating through the various zones of the building or other structure. As illustrated, the navigation area 58 may include a room indicator 64 and two directional arrows, shown as icons 60 and 62, for scrolling or toggling through the one or more available zones in the building or other structure. In the illustrative screen 56, the HVAC remote controller 24 is currently identifying the “LIVING ROOM” zone, as shown by room indicator 64. In this case, the HVAC remote controller 24 may display, set and/or control parameters related to the living room zone of the building or other structure. To navigate to a different zone of the building or other structure, a user may touch the left directional arrow icon 60 or right directional arrow icon 62. Touching the icons 60 or 62 may scroll or toggle through the available zones in the building or other structure.
When the left directional arrow icon 60 or the right directional arrow icon 62 is touched, the touch screen display 42 may switch from screen 56 to screen 66, shown in
In some cases, if the touch screen display 42 does not register a touch within a predetermined time period, the zone identified by room indicator 64 may be selected and the HVAC remote controller 24 may display screen 68 on the touch screen display as shown in
As illustrated, screen 68 shown in
In some cases, the HVAC remote controller 24 may provide for a predetermined loading period of time. In this case, if the HVAC remote controller 24 successfully establishes communication and successfully loads the parameters for the selected zone, screen 72 may be displayed. If, however, communication cannot be established between the HVAC remote controller 24 and the HVAC controller 8 of the selected zone within the predetermined loading period of time, screen 180 of
In some cases, the HVAC remote controller 24 may automatically select a corresponding zone, as the HVAC remote controller 24 is carried through the building or other structure. For example, the HVAC remote controller 24 may include a signal strength indicator that measures the signal strength from each of the identified HVAC zone controllers 8. The HVAC remote controller 24 may then automatically select the HVAC zone controller 8 that produces the highest signal strength. Alternatively, or in addition, each zone may include a zone ID device that, when the HVAC remote controller 24 is in the proximity of a zone ID device, the zone ID device informs the HVAC remote controller 24 which zone that the HVAC remote controller 24 is currently in. The HVAC remote controller 24 may then automatically select the appropriate zone.
Once the parameters for the currently selected zone have been loaded, the user may alter the settings for the zone via the user interface of the HVAC remote control unit. The one or more changed parameters and/or settings may then be sent to the zoned HVAC system via the wireless interface, wherein the zoned HVAC system may subsequently operate in accordance with the one or more changed parameters and/or settings in the selected zone. In some instances, the parameters and/or settings may be loaded from and sent to one or more wall mounted thermostats, if desired. The HVAC remote control unit may be configured to automatically detect and establish communication with each of two or more wall mounted thermostats either simultaneously, sequentially or by user selection, if desired.
In some instances, the HVAC remote control unit may be configured to dynamically change its behavior based on whether it detects a non-zoned or a zoned HVAC system. For example, if a non-zoned HVAC system is detected, the HVAC remote control unit may not display HVAC zone navigation area 58, and may control the HVAC system in accordance with an algorithm for a non-zoned HVAC system. Likewise, if a zoned HVAC system is detected, the HVAC remote control unit may display HVAC zone navigation area 58, and may control the HVAC system in accordance with an algorithm for a zoned HVAC system. In some cases, and for zoned HVAC systems, the behavior of the HVAC remote control unit may automatically change depending on the number of wireless thermostats that are detected. For example, the HVAC remote control unit may allow a user to navigate to each of the detected zones via HVAC zone navigation area 58, and may use an appropriate control algorithm (e.g. 2 zone algorithm, 3 zone algorithm, 4 zone algorithm, etc.) depending on the number of detected zones.
In some cases, when the battery level detected by the HVAC remote controller 24 decreases to or past a critical low battery threshold level, screen 80 of
In some cases, the HVAC controller 8 and/or HVAC remote controller 24 may include a control algorithm that automatically switches control from one device to the other. For example, if the temperature sensed by the temperature sensor of the HVAC remote controller 24 differs from the temperature sensor of the HVAC controller 8 by more than a threshold amount and/or for a threshold period of time, control may automatically switch from the HVAC remote controller 24 to the HVAC controller 8. Such a temperature differential may occur when, for example, the user is holding the HVAC remote controller 24 in his/her hand, when the HVAC remote controller 24 is set down next to an open door or window, set down outside, and/or set down in direct sun light. This is just one examples of when control may automatically switch from the HVAC remote controller 24 to the HVAC controller 8. Others are also contemplated, including those disclosed in U.S. patent application Ser. No. 11/948,971 filed on Nov. 30, 2007, and entitled “BUILDING CONTROL SYSTEM WITH REMOTE CONTROL UNIT AND METHODS OF OPERATION”, which is incorporated herein by reference.
As illustrated in
In some cases, it may take a period of time for the HVAC remote controller 24 to wirelessly communicate with the HVAC controller 8 and upload and/or download updated data. The updated data can include any suitable data including updated set points, updated sensed temperature readings, updated sensed humidity readings, updated system status information, updated operational data and/or other data, as desired. In some cases, this may take up to 20 seconds or more. In other cases, shorter transmit times are contemplated, including nearly instantaneously.
As indicated in
In some embodiments, when the user determines that control should be switched back to the temperature sensor of the HVAC remote controller 24, the user may touch the touch screen icon 40 to switch control back to the temperature sensor of the HVAC remote controller 24. When switching control back to the temperature sensor of the HVAC remote controller 24, and as shown in
In some cases, the HVAC remote controller 24 may include a predetermined timeout period where, if the HVAC remote controller 24 is unable to establish wireless communication with a HVAC controller 8, the HVAC remote controller 24 may display a “No Signal” screen, similar to screen 174 of
For those HVAC controllers that do allow hold operations, and referring to
As illustrated, screen 92 may provide a hold display region 94 when the set point is adjusted. In some cases, a temperature hold may be initiated by a user to maintain a desired hold temperature set point for a period of time, regardless of the current set point of a previously programmed temperature schedule. As shown, the hold display region 94 may include a border defining the region, but this is not required. The illustrative hold display region 94 may include a “hold until” display with a time indicating the time at which the hold temperature should end. For example, as illustrated, the hold time may end at 10:00 AM. The user may be able to adjust the hold end time by touching the touch screen display 42 adjacent to icon 100, which may include an up arrow for increasing the time, or by touching the touch screen display 42 adjacent to icon 102, which may be a down arrow for decreasing the time. If, for example, the user touches the touch screen display 42 adjacent to icon 100, screen 108 shown in
Referring to both screen 92 and 108 of
If a hold operation has been properly setup, the screen 110 of
The temperature hold operation may expire when the HVAC remote controller 24 and/or HVAC controller 8 determines that the current time is the same as the “hold until” time. In this case, when the hold operation expires, the HVAC remote controller 24 may return to its previously programmed settings and/or schedule. In some cases, this may cause the touch screen display 42 to display the appropriate home screen, such as, for example, home screen 30 of
In some cases, and referring to
When a touch is detected on the touch screen display 42 corresponding to icon 104 (permanent hold button on screens 92 and 108), the HVAC remote controller 24 may display touch screen 112, shown in
In some illustrative embodiments, when the user touches one or more icons shown in screen 112, the user may modify the current permanent hold set points and/or other options. In order to exit the permanent hold, the user may touch the touch screen display 42 adjacent to the “CANCEL” icon 98. In some cases, this ends the permanent hold operation and returns the touch screen display 42 to a home screen, such as, for example, home screen 30 of
During the permanent hold operation, if the user desires to switch the operational status or mode of the HVAC controller from heat to cool (or visa-versa), the user may touch the touch screen display 42 adjacent to the cool icon 34. When the user switches the operational status of the HVAC controller, the HVAC controller may switch its operational status to the cool mode, indicated by the bold outlined icon 34 and dot within icon 34 shown in screen 114 of

In some cases, if any other region of touch screen display 42 is touched when the touch screen display 42 is locked, the screen locked icon 132 may flash once or a number of times at a rate. In some cases, the flashing rate may be one-half a second, one second, or any other flash rate, as desired. In some cases, the “SCREEN LOCKED” text of screen 120 may be displayed, and may also flash.
As illustrated in
As illustrated, screen 134 may show the current inside temperature 48, the current outside temperature 46, the current time 44, the current heat set point without up or down arrows 136, the current operational status of the HVAC controller (e.g. heat 32, cool 34, and off 36), and the current device used for controlling the temperature of the HVAC comfort control system. In the illustrative embodiment, only the current operational status icon is displayed (e.g. heat mode 32), and not the other unselected options (cool mode, off mode). For example, when the HVAC controller is in heat mode, only icon 32 is displayed, and when the HVAC controller is in cool mode, as shown in
When in auto mode, the user may view the set points 50 of both the heat and cool modes. As illustrated on screen 142 of

In some cases, screen 192 may include a loading bar 86 indicating that the HVAC remote controller 24 is attempting to communicate with the HVAC controller 8. In some cases, this communication may be to upload and/or download cool mode set points, parameters, and/or other settings. In some cases, the communication may last for seconds or for minutes, depending on the application. When the cool set point information and/or other settings are uploaded to the HVAC remote controller 24, screen 194 shown in
