FIELD OF THE INVENTION
The present invention is directed to Heating Ventilating Air Conditioning (HVAC) system controller devices, and especially to a thermostat or other control unit for use with a HVAC system. The present invention is particularly useful with a residential HVAC system.
BACKGROUND OF THE INVENTION
HVAC systems have become more complex in recent years. Control units for use with HVAC systems have not been sufficiently detailed and varied in the information provided for a user to permit efficient use of features of the HVAC system. Complexity in programming and displaying information has caused some confusion to the extent that some users do not employ all of the features of an HVAC system, or find that the employment of some features is cumbersome.
Some attempts at facilitating the interface between a user and an HVAC control unit have involved limiting flexibility in the programming or display capabilities of the control unit. Such oversimplification of a control unit may also limit employment of features or capabilities of a HVAC system.
Prior art thermostat control devices generally require a user to enter a reminder interval or delay using a code corresponding to a time, such as a number of days. The time code is commonly provided in a user manual and is likely not something the user remembers. The capability to enter reminder delay interval or other time in terms of a number of months (or other predetermined time interval) in display 10 is a significant improvement in convenience and ease of use for a user.
There is a need for an improved control unit for use with HVAC systems that is intuitively easy to program.
There is a need for an improved control unit for use with HVAC systems that provides varied detail information for a user.
There is a need for an improved control unit for use with HVAC systems with which it is intuitively easy to program reminders.
SUMMARY OF THE INVENTION
A display apparatus for a control unit in an environmental control system includes: a display area presenting a plurality of first loci, a plurality of second loci and at least one third locus; each respective first locus of the plurality of first loci being responsive to pressure for effecting a respective response; each respective second locus of the plurality of second loci presenting information using a fixed segment data format; at least one third locus of the at least one third locus presenting information using a dot matrix data format.
A method for entering a reminder for display by an environmental control system includes: (a) providing a display area; the display area presenting a plurality of input loci for effecting selections associated with the control system; (b) in no particular order: (1) identifying at least one first selected input locus of the plurality of input loci; and (2) identifying at least one second selected input locus of the plurality of input loci; (c) operating the at least one first selected input locus to effect selection of a reminder function; and (d) operating the at least one second selected input locus to effect a time entry for a reminder; the time entry being expressed in terms of a predetermined multi-day time-unit.
It is, therefore, a feature of the present invention to provide an improved control unit for use with HVAC systems that is intuitively easier to program.
It is another feature of the present invention to provide an improved control unit for use with HVAC systems that provides varied detail information for a user.
It is yet another feature of the present invention to provide an improved control unit for use with HVAC systems with which it is intuitively easy to program reminders.

DETAILED DESCRIPTION
FIG. 1 is a plan view of a thermostat display configured according to the teachings of the present invention. In FIG. 1, a thermostat display 10 may be appropriate for use with a control unit in an environmental control system such as, by way of example and not by way of limitation, a Heating Ventilating Air Conditioning (HVAC) system. Display 10 may include a plurality of touch responsive loci configured to respond to pressure applied to respective touch responsive loci for effecting respective responses.
In the exemplary display 10 illustrated FIG. 1, touch responsive loci 12 may be generally indicated by delineated directional areas 201, 202, 203, 204, 205, 20n annotated with directional symbols indicating alteration or adjustment of a parameter up or down. Actuation may be carried out in any known manner, preferably by pressing or depressing an individual locus 20n in the manner of a touch screen input device known by those skilled in the art of design of control devices for HVAC systems. The indicator “n” is employed to signify that there can be any number of delineated directional areas in display 10. The inclusion of six delineated directional areas 201, 202, 203, 204, 205, 20n in FIG. 1 is illustrative only and does not constitute any limitation regarding the number of delineated directional areas that may be included in the display of the present invention.
Display 10 may include additional touch responsive first loci 14 generally indicated by functional action areas 221, 222, 223, 224, 225, 226, 22m annotated to indicate specified actions or functions that may be effected by actuating a respective area. Action area 221 permits effecting a “CANCEL” or “EDIT” action or function. Action area 222 permits effecting a “BACK” or “WAKE” action or function. Action area 223 permits effecting a “LEAVE” action or function. Action area 224 permits effecting a “CLEAN” or “RETURN” action or function. Action area 225 permits effecting an “ENTER” or “SLEEP” action or function. Action area 226 permits effecting an “EDIT” or “NEXT” action or function. Action area 22m permits effecting a “SAVE” action or function. The indicator “m” is employed to signify that there can be any number of functional action areas in display 10. The inclusion of seven functional action areas 221, 222, 223, 224, 225, 226, 22m in FIG. 1 is illustrative only and does not constitute any limitation regarding the number of functional action areas that may be included in the display of the present invention.
Display 10 may include additional touch responsive loci 16 generally indicated by mode controlling areas 241, 242, 24r annotated to indicate specified modes or controls that may be effected by actuating a respective area. Mode controlling area 241 permits effecting a “HEAT” mode, a “COOL” mode, an “AUTO” mode, an “OFF” mode or an “EM HEAT” (emergency heat) mode. Mode controlling area 242 permits effecting a fan mode of “ON”, “AUTO” or “CIRC” (circulate). Mode controlling area 24r permits effecting a schedule mode of “ON” or “OFF”. Actuation may be carried out in any known manner, preferably by pressing or depressing an individual locus 242 in the manner of a touch screen input device known by those skilled in the art of design of control devices for HVAC systems. The indicator “r” is employed to signify that there can be any number of mode controlling areas in display 10. The inclusion of three mode controlling areas 241, 242, 24r in FIG. 1 is illustrative only and does not constitute any limitation regarding the number of mode controlling areas that may be included in the display of the present invention.
Display 10 may include additional touch responsive loci 18 generally indicated by tab selecting areas 261, 262, 26s annotated to indicate specified separate control menus or tabs that may be effected by actuating a respective area. Tab selecting area 261 permits selecting a “HOME” menu or tab. Tab selecting area 262 permits selecting a “SCHEDULE” menu or tab. Tab selecting area 26s permits selecting an “OPTIONS” menu or tab. Actuation may be carried out in any known manner, preferably by pressing or depressing an individual locus 26m in the manner of a touch screen input device known by those skilled in the art of design of control devices for HVAC systems. The indicator “s” is employed to signify that there can be any number of tab selecting areas in display 10. The inclusion of three tab selecting areas 261, 262, 26s in FIG. 1 is illustrative only and does not constitute any limitation regarding the number of tab selecting areas that may be included in the display of the present invention.
Touch responsive areas 12, 14, 16, 18 may be configured using fixed segment display technology. Fixed segment display technology generally results in clear, crisp, well-defined displayed information. However, fixed segment display technology is generally inflexible and resistant to change. Fixed segment display technology is not readily amenable to presenting custom messages or similar ad hoc information displays. Displays employing fixed segment display technology do not permit in-the-field changes in displayed information to accommodate differing needs among different users.
Display 10 may include a display locus 30 configured to employ dot matrix display technology. Dot matrix display technology is readily accepting of changes so that customizable messages or other information may be presented using dot matrix display technology responsive to changes entered by a user. Display locus 30 may include a message zone 32 for display of customized messages, alerts or other displays. Display locus 30 may further include touch responsive loci 34, generally indicated by customizable selecting areas 361, 362, 363, 364, 36t annotated to indicate specified separate control functions or selections that may be effected by pressing or otherwise actuating a respective area. Each of customizable selecting areas 361, 362, 363, 364, 36t may be programmed to effect a predetermined response in reaction to pressure applied to a respective customizable area. The particular response to touching may be indicated by a customized message in display area 30 using dot matrix display technology. The indicator “t” is employed to signify that there can be any number of customizable selecting areas in display 10. The inclusion of five customizable selecting areas 361, 362, 363, 364, 36t in FIG. 1 is illustrative only and does not constitute any limitation regarding the number of customizable selecting areas that may be included in the display of the present invention. Alternatively, selecting areas 361, 362, 363, 364, 36t may be non-responsive to touch but may be employed to effect labeling of associated touch-responsive areas located substantially adjacent to selecting areas 361, 362, 363, 364, 36t. By way of example and not by way of limitation, selecting area 361 may be employed to label functional area 222 for use as a selecting button associated with an element displayed in message zone 32. Selecting area 362 may be employed to label functional area 223 for use as a selecting button associated with an element displayed in message zone 32. Selecting area 363 may be employed to label functional area 224 for use as a selecting button associated with an element displayed in message zone 32. Selecting area 364 may be employed to label functional area 225 for use as a selecting button associated with an element displayed in message zone 32. Selecting area 36t may be employed to label functional area 226 for use as a selecting button associated with an element displayed in message zone 32.
Other areas of display 10 may be configured for display only without providing a coincident touch sensitive area for receiving user inputs such as, by way of example and not by way of limitation, display-only areas 401, 402, 403, 404, 40u. Display-only areas 401, 402, 403, 404, 40u may employ any display technology, but preferably employ fixed segment display technology. By way of example and not by way of limitation, display-only area 40 may display up to two digits indicating a set temperature for a HEAT mode of operation, display-only area 402 may display up to two digits indicating a set temperature for a COOL mode of operation, display-only area 403 may display an “F” indicator indicating degrees Fahrenheit or a “C” indicator indicating degrees Celsius, and display-only areas 404, 40u may cooperate to display up to two digits indicating an extant indoor temperature. The indicator “u” is employed to signify that there can be any number of display-only areas in display 10. The inclusion of five display-only areas 401, 402, 403, 404, 40u in FIG. 1 is illustrative only and does not constitute any limitation regarding the number of display-only areas that may be included in the display of the present invention.
Day-of-week indicators “MON” (Monday), “TUE” (Tuesday), “WED” (Wednesday), “THU” (Thursday), “FRI” (Friday), “SAT” (Saturday) and “SUN” (Sunday) are illustrated as being included within message zone 32 and configured using dot-matrix display format. Day-of-week indicators may be situated outside of message zone 32 and configured using fixed segment display format if desired.
Employment of fixed segment display technology and dot matrix display technology in display 10 permits designing display 10 so that frequently used controls and associated information displays such as, by way of example and not by way of limitation, controls and information related with touch responsive loci 12, 14, 16, 18 may be rendered in highly readable fixed segments. Mixing display technologies also permits dynamic information to be rendered in dot matrix display technology to present customizable text messages clearly understandable by a user and instructive to a user.
By way of example and not by way of limitation, system status indications on prior art thermostat display units have typically been effected using fixed indicators such as a light indicator, a code display or a fixed Liquid Crystal Display (LCD) text. Such fixed indicators are not generally descriptive so that a user, such as a homeowner, may be left wanting more information than is provided by the indicator. This may be the case when a “trouble” indicator such as a lighted or blinking Light Emitting Diode (LED) indicator is actuated, but no indication of the exact problem is available without consulting a user's manual. Further, because the indicators are in fixed positions on the display screen there is not a single place on the screen or other user interface that one can always look at to determine whether there are any problems. An indicator of system status could be located anywhere on the display screen making it difficult to review system status. Difficulty in reviewing system status may create a possibility of a critical message being inadvertently overlooked.
Providing a variable display area such as display area 30 using a technology permitting variation of information presented permits a user to look to a particular area of display 10, such as display area 30, to quickly and assuredly determine whether the system is operating properly and, if not, what the nature of an extant problem may be.
FIG. 2 is a first view of the display illustrating features associated with the HOME Tab. In FIG. 2, HOME tab selecting area 261 is depressed or otherwise actuated to orient display 10 in an exemplary “HOME” configuration. Display 10 is preferably configured with a backlit screen with adjustable brightness and presents large graphics so as to be easy to read and easy to use.
A user's depressing or otherwise actuating HOME tab selecting area 261 configures display 10 for displaying current system operations including, by way of example and not by way of limitation, display of indoor temperature (display only areas 404, 40u) and heating and cooling set points (display only areas 401, 402) and permits a user to make adjustments to system operation. The HOME tab may be actuated automatically pursuant to satisfying predetermined conditions. By way of example and not by way of limitation, the HOME tab may be actuated when there is a period of inactivity (e.g., 60 seconds) while a user is on either the SCHEDULE tab or the OPTIONS tab
In the “HOME” configuration illustrated in FIG. 2, touch responsive loci 12 are partially presented to provide directional areas 201, 202, 203, 204; touch responsive loci 14 are generally not presented to a user; touch responsive loci 16 are generally fully presented (touch responsive loci 16 are represented in FIG. 2 as having experienced selection by a user to establish an AUTO Mode with Fan in AUTO and Schedule ON); and touch responsive loci 18 are generally fully presented as having experienced selection by a user to establish the HOME configuration.
Providing a “file folder” type of display organization using TABS selectable by depressing or otherwise activating tab selecting areas 261, 262, 26s avoids cluttering display 10 with menu selections that are not relevant to an extant selection task. As prior art thermostat control displays added more and more capability to control an associated HVAC system, the number of buttons and menu screens became more and more complicated. A result was complex control or programming procedures that were cumbersome to execute, even with the aid of an associated user's manual. Providing TABS improves intuitive easy navigating among functions programmable or selectable using display 10. Grouping configuration and control options on logical TABS on the user interface, i.e. display 10, provides a user with displays familiar to users, especially to users having experience dealing with such software programs as MS Excel (a trademark of Microsoft Corporation) and various web browser programs. Tabbed interface permits users to quickly navigate to and control features of a system.
If an outdoor temperature sensor is installed (not shown in FIG. 2), display area 30 may display outdoor temperature, or relative humidity, or both outdoor temperature and relative humidity (only outdoor temperature is illustrated as displayed in FIG. 2), along with accompanying information such as, by way of example and not by way of limitation, date and time.
By way of example and not by way of limitation, display 10 may be operated in the HOME configuration illustrated in FIG. 2 to permit a user to actuate the SCHED button 24r to select SCHED ON so that the controlled system (not shown in FIG. 2) will follow a pre-programmed schedule. A user may again depress or otherwise actuate the SCHED button to select SCHED OFF for non-programmed, manual system operation.
Prior art thermostat controls generally always have a pre-programmed operation running so that heating and cooling set points are changed according to pre-programmed settings when a predetermined time is reached. If a user wished to disable the pre-programmed operation using a prior art thermostat control the user was required to put the thermostat in a “permanent hold” state. The term “permanent hold” proved to be confusing to many users. Further, if a user wished to change temperature setting of a thermostat control there was a requirement that the user perform another permanent hold regarding the newly set temperature set point. In short, the process for changing a programmed temperature was sometimes cumbersome, frustrating and confusing to users. Providing a SCHED button permitting a user to easily press a single button for placing a system in a SCHED ON mode for following a pre-programmed schedule or in a SCHED OFF mode for non-programmed, manual operation is intuitively easy for a user to understand and carry out.
FIG. 3 is a second view of the display illustrating features associated with the HOME Tab. In FIG. 3, display 10 remains in the HOME tab but is additionally configured for effecting a Temporary Schedule Hold setting. Display 10 may be configured so that while in the HOME tab, anytime a temperature set point (displayed at display-only areas 401, 402 is changed, a display is presented in display area 30 relating to setting a Temperature Schedule Hold mode of operation. In the Temporary Schedule Hold mode the HOME tab display is altered somewhat to provide selection buttons within display area 30 for effecting a Temporary Schedule Hold entry. Specifically, touch responsive loci are oriented to present a CANCEL button 221, a Time Selecting button 223 (labeled in cooperation with display area 30), a Date Selecting button 225 (labeled in cooperation with display area 30), an UP arrow 205, a DOWN arrow 20n and a SAVE button 22m.
Additionally, in the Temporary Schedule Hold mode, display area 30 displays a time and date until which a temporary hold is to be maintained. Selectively actuating Time Selecting button 223 or Date Selecting button 225 permits a user to pause a pre-programmed schedule for a time set using Time Selecting button 223 or Date Selecting button 225 to set the time and date it is desired that the pre-programmed schedule is to resume. By way of example and not by way of limitation, a temporary schedule hold may be imposed for a time interval ranging from a few hours up to forty-five days.
FIG. 4 is a view of the display illustrating features associated with the SCHEDULE Tab. In FIG. 4, SCHEDULE tab selecting area 262 is depressed or otherwise actuated to orient display 10 in an exemplary “SCHEDULE” configuration. A user's depressing or otherwise actuating SCHEDULE tab selecting area 262 configures display 10 for displaying a programming screen to permit a user to select temperatures for certain times of day such as, by way of example and not by way of limitation, time of waking (WAKE time), time of leaving one's house for work (LEAVE time), time returning to house after work (RETURN time) and time of going to sleep (SLEEP time).
Display 10 may permit a user to schedule or program events for an entire week, as indicated by inclusion of all days of the week in display area 30. Alternately, selected subsets of the week may be programmed separately such as, by way of example and not by way of limitation, scheduling events according to the same schedule for a Monday-Friday workweek with a different schedule set for weekends. Another choice may be for a user to schedule events for each individual day of the week. Opting among subsets of a week for scheduling may be effected by depressing or otherwise actuating the NEXT button 226 among touch responsive loci 14.
In the “SCHEDULE” configuration illustrated in FIG. 4, touch responsive loci 12 are generally not presented to a user; touch responsive loci 14 are generally presented to a user as described in connection with FIG. 1 (functional action areas 221, 222, 223, 224, 225, 226) with no SAVE button (22m) presented. In this SCHEDULE configuration functional action areas are as labeled in the bottom portion of areas illustrated in FIG. 1. Thus, functional action area 221 affects an EDIT function, functional action area 222 affects a WAKE time setting; functional action area 223 affects a LEAVE time setting, functional action area 224 affects a RETURN time setting; functional action area 225 affects a SLEEP time setting and functional action area 226 affects a NEXT function. Touch responsive loci 16 are generally presented only in terms of a FAN mode selection button with the Fan in AUTO in FIG. 4. Touch responsive loci 18 are generally fully presented as having experienced selection by a user to establish the SCHEDULE configuration.
FIG. 5 is a first view of the display illustrating features associated with the OPTIONS Tab. FIG. 6 is a second view of the display illustrating features associated with the OPTIONS Tab. FIG. 7 is a third view of the display illustrating features associated with the OPTIONS Tab. Regarding FIGS. 5-7 together, OPTIONS tab selecting area 26s is depressed or otherwise actuated to orient display 10 in an exemplary “OPTIONS” configuration. A user's depressing or otherwise actuating OPTIONS tab selecting area 26s configures display 10 for displaying a scrolling list of adjustable settings.
In the “OPTIONS” configuration illustrated in FIGS. 5-7, touch responsive loci 12 are generally presented to a user as described in connection with FIG. 1 only in so far as two selecting or scrolling buttons are represented, such as delineated directional areas 205, 20n. Touch responsive loci 14 are generally presented to a user as described in connection with FIG. 1 only in so far as two functional action areas 224, 225 are represented. In this OPTIONS configuration functional action areas are as labeled in the top portion of areas illustrated in FIG. 1. Thus, functional action area 224 affects a CLEAN function, functional action area 225 affects an ENTER function. Touch responsive loci 16 are generally not presented to a user. Touch responsive loci 18 are generally fully presented as having experienced selection by a user to establish the OPTIONS configuration.
By way of example and not by way of limitation, a user may employ delineated directional areas 205, 20n to scroll through a list of adjustable settings presented in display area 30 (FIG. 5). Adjustable settings are highlighted or otherwise differentiated from other adjustable settings as each becomes available for selection. When a desired adjustable setting is highlighted or otherwise indicated as available for selection, a user may depress or otherwise actuate the ENTER button 225 to select the adjustable setting to be adjusted. Other sub-lists may be displayed. Eventually a user will be able to indicate and select a particular setting for adjustment, the user may then depress or otherwise actuate the ENTER button 225 to select the indicated setting for adjustment and then delineated directional areas 205, 20n may be employed to adjust the setting upward or downward until the desired setting level is achieved.
By way of example and not by way of limitation, one may scroll to a setting USER SETTINGS, select USER SETTINGS and be presented with a sub-list or sub-lists that ultimately permit a user to establish settings such as Date, Time, Events per Day, Backlight Intensity, Backlight Setting or Security Lock.
Similarly a user may scroll to a setting REMINDERS, select REMINDERS and ultimately select from a series of service, parts replacement, maintenance or custom reminders (FIG. 6). As the function of display 10 changes, (e.g., selecting an adjustable setting (FIG. 5) or displaying a reminder (FIG. 6)) the particular respective functional areas 22m presented to a user may change. FIG. 6 illustrates that functional areas 222 (BACK) and 226 (EDIT) may be presented to a user while viewing reminder messages. The selected reminders may be displayed in display area 30 when display 10 is in the HOME configuration (FIG. 2).
As indicated in FIG. 7, contact information relating to one's HVAC dealer or repair facility may be selected while in the OPTIONS configuration and may appear on display 10 in the HOME configuration when a critical system error occurs. Prior art thermostat display units typically are provided with an adhesive sticker or decal for adhering to the housing of the thermostat with contact information relating to a HVAC dealer or repair facility. Homeowners sometimes regard such stickers as unsightly and remove them. If their system needs service, there is a problem determining how to contact the repair facility.
Entering appropriate service and repair contact information in memory of a thermostat permits its display of the information without requiring a sticker. Further, the system may be programmed to recognize circumstances under which it would be advisable to contact a repair facility and automatically display the contact information when such circumstances occur.
More than one message may be displayed in display area 30 using a “slide show” technique successively displaying each message for a predetermined time, using a “scrolling” display by which the message displays are rolled by for a viewer's perusal or using another multi-message display technique.
FIG. 8 is a first view of the display illustrating programming steps associated with Mode of operation. FIG. 9 is a second view of the display illustrating programming steps associated with Mode of operation. Regarding FIGS. 8-9 together, a user may touch display 10 generally anywhere to activate the backlight and render display 10 easy to read.
In programming heating and cooling set point temperatures in a system using display 10, a user places display 10 in a HOME configuration substantially as described above in connection with FIG. 2. To set or program a temperature, a user may press the MODE button 241 repeatedly to select a choice of system operation (i.e., HEAT, COOL, AUTO, OFF, EM HEAT). AUTO allows the thermostat unit to automatically switch between heating and cooling as dictated by the indoor temperature. EM HEAT (Emergency Heat) is used to disable heat pump operation on very cold days and use electric strip heating or fossil fuel heating instead.
A user may press UP arrow 201 or DOWN arrow 202 to program a desired heating set point (displayed at display-only area 401). A user may press UP arrow 203 or DOWN arrow 204 to program a desired cooling set point (displayed at display-only area 402). A user may press UP arrow 205 or DOWN arrow 20n to program a desired time (selected by time selection button 223) and date (selected by date selection button 225) the user desires that the schedule resume (displayed at display area 30).
FIG. 10 is a first view of the display illustrating programming steps associated with operation Schedule. FIG. 11 is a second view of the display illustrating programming steps associated with operation Schedule. FIG. 12 is a third view of the display illustrating programming steps associated with operation Schedule. Regarding FIGS. 10-12 together, a user may touch display 10 generally anywhere to activate the backlight and render display 10 easy to read.
In programming a schedule in a system using display 10, a user places display 10 in a SCHEDULE configuration substantially as described above in connection with FIG. 4. In the SCHEDULE configuration display 10 may appear substantially as presented in FIG. 11. To set or program a schedule, a user may press EDIT button 221 and then press NEXT button 226 repeatedly to select a grouping of days displayed in display area 30.

By way of example and not by way of limitation, a user may then select REPLACE MEDIA FILTER by pressing or otherwise actuating ENTER button 225 when REPLACE MEDIA FILTER is displayed in display area 30 (FIG. 22).
Thereafter, a user may press EDIT button 226 to select a first editable element associated with REPLACE MEDIA FILTER. A user may use arrows 205, 20n to select whether it is desired to modify or edit CALENDAR TIME or RUN TIME, and press ENTER button 225 to complete the selection of CALENDAR TIME or RUN TIME (FIG. 23).
A user may thereafter press or otherwise actuate RESET button 223 or EDIT button 225 (labeled in cooperation with display area 30) and use arrows 205, 20n to set time for the service reminder being programmed (FIG. 24). By way of example and not by way of limitation one may set the time for a reminder for a period ranging from one month to twenty-four months (FIG. 25). A user may thereafter press SAVE button to save the programming steps entered. Pressing or otherwise actuating HOME tab 261 returns display 10 to its HOME configuration (FIG. 26). Service reminders are displayed in display area 30 in the HOME configuration at the programmed date.
Display 10 permits resetting a reminder, such as a service reminder, directly from display screen 10 without having to go to a special set-up or configuration screen. With many prior art thermostat devices one must dismiss and reset (or at least reset) the reminder using a special set-up or configuration screen requiring a user manual to know how to perform the operation. Often a homeowner does not know how to carry out this programming evolution so the service reminder message is never reset and the feature is rendered substantially useless. Display 10 permits resetting the reminder time interval directly when it appears on display 30 using a reset button 225 (FIG. 26; labeled in cooperation with display area 30) without having to go to little used and unfamiliar special set-up or configuration screen. This direct reset capability increases usability of the feature.
A reminder button 222 (FIG. 26; labeled in connection with display area 30) permits a user to direct the system served by a thermostat using display 10 to remind the user at a later time of the need for a service such as, by way of example and not by way of limitation, redisplaying the reminder message, displaying the reminder message in a flashing mode, emitting an audible alert or another reminder technique. This “Remind Later” feature may be useful when a homeowner does not have a replacement filter handy when the reminder is first displayed. The “Remind Later” feature permits a user to dismiss a reminder temporarily without having to reset the reminder or having to see the reminder displayed continuously until reset. The remind period may be a predetermined maximum time such as, by way of example and not by way of limitation, seven days.
Prior art thermostat control devices generally require a user to enter a reminder interval or delay using a code corresponding to a time, such as a number of days. The time code is commonly provided in a user manual and is likely not something the user remembers. The capability to enter reminder delay interval or other time in terms of a number of months (or other predetermined time interval) in display 10 is a significant improvement in convenience and ease of use for a user.
Display 10 could be provided with access to a stored calendar. Such a stored calendar could be contained within a processor device associated with a control device operating with display 10 (not shown in detail in FIGS. 1-51). In such an arrangement, a user could select a “calendar function” and scroll through calendars to select a particular date for a reminder to be displayed.

A user may then press UP arrow 205 or DOWN arrow 20n to scroll through a list of NON HEAT PUMP choices presented in display area 30 (FIG. 47). A user may then select ELECTRIC (indicating an electric system is controlled by a thermostat employing display 10 rather than a gas system) by pressing or otherwise actuating ENTER button 225 when ELECTRIC is displayed in display area 30 (FIG. 47).
After indicating that the system is an ELECTRIC system, a user may be again be presented with a list of SYSTEM SETUP choices presented in display area 30. A user may scroll among the displayed settings using UP arrow 205 or DOWN arrow 20n and may then select COMPRESSOR STAGES by pressing or otherwise actuating ENTER button 225 when COMPRESSOR STAGES is displayed in display area 30 (FIG. 48). A user may then press UP arrow 205 or DOWN arrow 20n to scroll through a list of COMPRESSOR STAGES choices presented in display area 30. A user may then select “1” (indicating that the system controlled by a thermostat employing display 10 has a single compressor stage) by pressing or otherwise actuating SAVE button 22m when “1” is displayed in display area 30 (FIG. 48).
A message INDOOR HEAT STAGES may thereafter be displayed in display area 30 (FIG. 49), and a user may then press UP arrow 205 or DOWN arrow 20n to scroll through a list of INDOOR HEAT STAGES choices presented in display area 30. A user may then select “1” (indicating that the system controlled by a thermostat employing display 10 has a single indoor heat stage) by pressing or otherwise actuating SAVE button 22m when “1” is displayed in display area 30 (FIG. 49). A user may then depress BACK button 222, followed by UP arrow 205 or DOWN arrow 20n to scroll through a list of selections until STG 1 DIFF appears in display area 30 (FIG. 50) and is selected by pressing or otherwise actuating ENTER button 225.
This exemplary set of selections (FIGS. 45-50) would be appropriate, by way of example and not by way of limitation, when a system controlled by a thermostat employing display 10 is a non heat pump system providing electric heat and having a one-stage compressor and one stage of indoor heat. In such an exemplary system, menu items such as, by way of example and not by way of limitation, STG 2 DIFF and STG 3 DIFF would be hidden and not displayed to a user.
Prior art HVAC system controller displays typically present all menu items regardless of whether the physical equipment is connected or otherwise installed or included with the system being controlled. This display of menu items with which a user may be unfamiliar (because the user may have no need to deal with the menu item) may be confusing and worrisome to a user. The user—whether a dealer or a homeowner—may be led to mistakenly believe that there is a need to set a control parameter for something that does not exist in the system at hand.
Providing a capability to hide menu items not associated with a system at hand, as described in connection with FIGS. 45-50, removes irrelevant distractions not associated with equipment installed. By way of example and not by way of limitation, if a dealer configures a system for a single stage furnace no options will be displayed that pertain to second stage settings. By way of further example and not by way of limitation, if a system has not been configured with a humidifier, then no humidification settings will be displayed.
FIG. 51 is a flow chart illustrating the method of the present invention. In FIG. 51, a method 100 for entering input to an environmental control system begins at a START locus 102. Method 100 continues with providing a display area, as indicated by a block 104.
Method 100 continues with, in no particular order: (1) presenting a plurality of first loci in the display area, as indicated by a block 106; (2) presenting a plurality of second loci in the display area, as indicated by a block 108; and (3) presenting at least one third locus in the display area, as indicated by a block 110.
Method 100 continues with, in no particular order: (1) configuring each respective first locus of the plurality of first loci for being responsive to pressure for effecting a respective input, as indicated by a block 112; (2) configuring each respective second locus of the plurality of second loci presenting information using a fixed segment data format, as indicated by a block 114; and (3) configuring at least one third locus of the at least one third locus presenting information using a dot matrix data format, as indicated by a block 116. Method 100 terminates at an END locus 118.
Display 10 avoids requiring a user to navigate to system settings by entering a configuration mode, selecting a configuration or other code to configure and then entering or selecting a configuration parameter. Display 10 also avoids requiring a user having to “drill down” through layers of menus by pressing a “next” or “back” button to enter a configuration mode, select a configuration or other code to configure and enter or select a configuration parameter, as is required when operating prior art HVAC control devices. In contrast, display 10 permits a user to scroll through a list of menu items until a desired programmable item is displayed. Thereafter, a user can enter parameters desired for effecting programming of the desired item in real text without having to deal with configuration codes, a user's manual or similar complications.
It is to be understood that, while the detailed drawings and specific examples given describe preferred embodiments of the invention, they are for the purpose of illustration only, that the apparatus and method of the invention are not limited to the precise details and conditions disclosed and that various changes may be made therein without departing from the spirit of the invention which is defined by the following claims:
