Abstract

An electronic programmable thermostat having a plurality of program sets, each comprising a plurality of times and a corresponding plurality of temperatures is disclosed. To program the thermostat, the user merely selects a program set and the plurality of times and temperatures corresponding to the selected program set is programmed into the thermostat to control the heating and/or cooling systems controlled by the thermostat.

Claims

1. A method of programming a programmable thermostat with one of a plurality of built-in program sets, where each built-in program set comprises a plurality of times and at least a plurality of temperatures, said method comprising the steps of:

selecting a desired one of said plurality of built-in program sets and programming said programmable thermostat with the times and temperatures associated with the desired built-in program set.

2. The method of claim 1 wherein said step of storing said plurality of built-in program sets comprises a step of storing a plurality of standard program sets, said method further comprising the step of deriving said desired program set from one of said standard program sets.

3. The method of claim 2 further comprising the step of a user selecting one of said plurality of standard program sets.

4. A programmable thermostat comprising:

a first memory which may be programmed with at least a desired one of a plurality of built-in program sets;

user selection means for enabling a user to select an alphanumeric identifier corresponding to at least one desired built-in program set;

means responsive to said user selection means for causing the desired built-in program set to be stored in said first memory.

11. The programmable thermostat of claim 4 wherein said first plurality of temperatures is used for controlling a heating system and said second plurality of temperatures is used for controlling a cooling system.

5. A programmable thermostat comprising:

a first memory which may be programmed with at least a desired one of a plurality of built-in program sets, wherein each program built-in set comprises a plurality of times and at least one set of a corresponding number of temperatures;

user selection means for enabling a user to select said at least one desired built-in program set; and

means responsive to said user selection means for causing the times and temperatures of said desired program built-in set to be stored in said first memory.

6. The programmable thermostat of claim 5 wherein said desired built-in program set comprises a plurality of times and a corresponding plurality of temperatures and said thermostat further comprises a second memory means for storing at least one standard program set having a plurality of times and at least a corresponding plurality of temperatures and wherein the plurality of times of said desired program set has a predetermined relationship with respect to the plurality of times of said standard program set.

7. The programmable thermostat of claim 5 further comprising a second memory for storing a plurality of built-in program sets and wherein said user selection means is used to select one of said plurality of built-in program sets stored in said second memory.

8. The programmable thermostat of claim 5 wherein each built-in program set comprises a plurality of times and a first corresponding plurality of temperatures and a second corresponding plurality of temperatures.

9. The programmable thermostat of claim 8 wherein said first plurality of temperatures correspond to temperatures for controlling a heating system.

10. The programmable thermostat of claim 8 wherein said second plurality of temperatures correspond to temperatures for controlling a cooling system.

12. A programmable thermostat comprising:

a first memory which is programmable;

a second memory for storing a plurality of built-in program sets, where each built-in program set comprises a plurality of times and at least a corresponding number of associated temperatures;

user selection means for enabling a user to select a desired one of said stored built-in program sets; and

means responsive said user selection means for causing the times and associated temperatures of said selected built-in program set to be stored in said second memory.

13. A programmable thermostat comprising:

a first memory which is programmable;

a second memory for storing at least one standard program set, wherein said standard program set comprises a plurality of times and at least a corresponding number of associated temperatures;

user selection means for enabling a user to select a desired program set to be stored in said second memory, wherein at least one of said times and temperatures of said desired program set have a predetermined relationship with respect to the times and temperatures of said standard built-in program so that said desired program may be derived from said standard built-in program; and

means responsive said user selection means for causing the times and associated temperatures of said desired program set to be stored in said first memory.

14. The programmable thermostat of claim 13 wherein said second memory comprises a plurality of standard program sets, and wherein said user selection means further comprises means for selecting one of said plurality of standard program sets and wherein said desired program set is derived from said selected standard program set.

15. The programmable thermostat of claim 13 wherein each program set comprises a plurality of times and a first corresponding plurality of temperatures and a second corresponding plurality of temperatures.

16. The programmable thermostat of claim 15 wherein said first plurality of temperatures is used for controlling a heating system.

17. The programmable thermostat of claim 15 wherein said second plurality of temperatures is used for controlling a cooling system.

18. The programmable thermostat of claim 15 wherein said first plurality of temperatures is used for controlling a heating system and said second plurality of temperatures is used for controlling a cooling system.
