Abstract

A programmable controller includes a user interface which includes a default interface, a home screen, an indoor settings interface and one or more tab interfaces. As the home screen covers a predominant portion of the default interface and is associated with the indoor settings interface, the home screen enables an operator of the programmable thermostat to intuitively transition from the home screen to the indoor settings and one or more tab interfaces.

Claims

1. A programmable controller for controlling an HVAC system, comprising:

a touch screen; and

a processor subsystem coupled to said touch screen;

said processor subsystem configured;

     1) to generate a first interface that a) includes primary and secondary subinterfaces that together utilize substantially all of an available display area of said touch screen, and b) displays a set of one or more physical conditions produced by operation of said HVAC system and,

     2) to generate, in response to a touch of said primary subinterface a second interface from which one or more thermostat settings for said HVAC system may be modified, and,

     3) to generate, in response to a touch of said secondary subinterface a third interface from which one or more settings for said HVAC system may be modified,

wherein an area of said primary subinterface configured to generate said second interface comprises an entirety of said primary subinterface with the exception of one or more displayed control buttons contained within said primary subinterface and configured to change one of said thermostat settings.

2. The programmable controller of claim 1, wherein a first thermostat setting for said HVAC system is displayed on, and modifiable from, said second interface.

3. The programmable controller of claim 2, wherein both said first interface and said second interface display a second thermostat setting for said HVAC system, said second thermostat setting being modifiable from said second interface.

4. The programmable controller of claim 1, wherein a first physical condition is displayed on both said first interface and said second interface.

5. The programmable controller of claim 1, wherein current indoor temperature is displayed on both said first interface and said second interface, a first thermostat setting is operating mode and a second thermostat setting is temperature setpoint.

6. The programmable controller of claim 1, wherein said primary subinterface is coextensive with a predominant portion of said first interface that is less than an entirety of said first interface, and said secondary subinterface is coextensive with a remaining portion of said first interface.

7. The programmable controller of claim 1, wherein said processor subsystem is further configured to generate said response to a touch of said primary subinterface for a first duration, and to generate said response to a touch of said secondary subinterface for a different second duration.

8. A user interface for a programmable HVAC system controller, comprising:

a first interface having primary and secondary subinterfaces that together utilize substantially all of an available display area, said primary subinterface having an area in which a value for a physical parameter is displayed; and

a second interface having a first control button for selecting a conditioning process capable of modifying said value of said physical parameter;

wherein

said second interface is generated in response to a touch of said primary subinterface; and

a third interface is generated in response to a touch of said secondary subinterface,

wherein an area of said primary subinterface configured to generate said second interface comprises an entirety of said primary subinterface with the exception of a second control button contained within said primary subinterface and configured to change one of said one or more thermostat settings of said HVAC system.

9. The user interface of claim 8, wherein a first thermostat setting is displayed in said primary subinterface and said second interface includes a third control button for modifying one of said one or more thermostat settings.

10. The user interface of claim 9, wherein said first interface includes a fourth control button for modifying said one of said one or more thermostat settings.

11. The user interface of claim 8, wherein said primary subinterface is coextensive with a predominant portion of said first interface that is less than an entirety of said first interface, and said secondary subinterface is coextensive with a remaining portion of said first interface.

12. The user interface of claim 8, wherein said processor subsystem is further configured to generate said response to a touch of said primary subinterface for a first duration, and to generate said response to a touch of said secondary subinterface for a different second duration.

13. A user interface for a programmable controller for controlling an HVAC system, the user interface comprising:

a default interface, said default interface including primary and secondary subinterfaces that together utilize substantially all of an available display area, and being generated in response to an absence of operator inputs;

a home screen, said home screen being coextensive with said primary subinterface, said home screen displaying a current indoor temperature, an indoor temperature setpoint and an operating mode; and

an indoor settings interface, said indoor settings interface having a first control for modifying said indoor temperature setpoint and a second control for selecting said operating mode;

wherein said indoor settings interface is generated in response to a touch of said home screen, and an installer interface is generated in response to a touch of said secondary subinterface

wherein an area of said home screen configured to generate said indoor settings interface comprises an entirety of said primary subinterface with the exception of one or more displayed control buttons entirely contained within said home screen and configured to change said indoor temperature setpoint.

14. The user interface of claim 13, and further comprising:

at least one tab interface; and

at least one further settings interface, each of said further settings interface associated with a corresponding one of said at least one tab interface;

wherein in response to a touch of a selected one of said at least one tab interface, a further settings interface associated with said selected tab interface is generated.

15. The user interface of claim 14, wherein:

said at least one tab interface includes one or more of a weather tab, a programming tab, an indoor humidity tab, a zoning tab and an alert tab; and

wherein;

said at least one further settings interface includes one or more of a weather interface, a programming interface, an indoor humidity interface, a zoning interface and an alert interface.

16. The user interface of claim 15, and further comprising:

a home tab;

wherein said home tab is generated in response to a touch of said home screen; and

wherein said home screen is generated in response to a touch of said home tab.

17. The user interface of claim 13, wherein said first control comprises a first control button for raising said indoor temperature setpoint in response to a touch thereof and a second control button for lowering said indoor temperature setpoint in response to a touch thereof.

18. The user interface of claim 13, wherein said second control comprises a control button for selecting said operating mode in response to a touch thereof.

19. The user interface of claim 18, wherein, by touching said control button, said operating mode may be switched between “

heat only”

, “

cool only”

, “

heat &

cool” and

“

off”

settings.

20. The user interface of claim 13, wherein said primary subinterface is coextensive with a predominant portion of said first interface that is less than an entirety of said first interface, and said secondary subinterface is coextensive with a remaining portion of said first interface.

21. The user interface of claim 13, wherein said processor subsystem is further configured to generate said response to a touch of said primary subinterface for a first duration, and to generate said response to a touch of said secondary subinterface for a different second duration.
