Abstract

A computer readable medium containing instructions that when executed by a computer performs steps to affect temperature. The steps include defining a desired temperature as a first value; activating an HVAC device if a current temperature achieves a first condition relative to the desired temperature; deactivating the HVAC device if the current temperature achieves a second condition relative to the desired temperature; and defining the desired temperature as a second value if the current temperature does not achieve the second condition within a first time period.

Claims (49)

1. A non-transitory computer readable medium having instructions thereon, wherein the instructions when executed by a computer cause the computer to preform operations to affect temperature comprising:

defining a desired temperature as a first value;

activating a HVAC device if a current temperature achieves a first condition relative to the desired temperature;

deactivating the HVAC device if the current temperature achieves a second condition relative to the desired temperature;

defining the desired temperature as a second value and deactivating the HVAC device if the current temperature does not achieve the second condition within a first time period.

2. The non-transitory computer readable medium of claim 1 , further comprising: after defining the desired temperature as the second value, if the current temperature does not achieve a third condition within a second time period, defining the desired temperature as a third value.

3. The non-transitory computer readable medium of claim 1 , further comprising: after defining the desired temperature as the second value, if the current temperature achieves a third condition relative to the desired temperature within a third time period, defining the desired temperature as a fourth value.

4. The non-transitory computer readable medium of claim 1 , wherein the first condition is four degrees warmer in a cooling mode and is four degrees cooler in a heating mode.

5. The non-transitory computer readable medium of claim 1 , wherein the second condition is two degrees cooler in a cooling mode and is two degrees warmer in a heating mode.

6. The non-transitory computer readable medium of claim 1 , further comprising: determining information regarding a sleep status of an individual located within the area affected by the HVAC device.

7. The non-transitory computer readable medium of claim 6 , further comprising: adjusting the desired temperature by considering the information regarding sleep status of the individual.

8. A non-transitory computer readable medium having instructions thereon, wherein the instructions when executed by a computer cause the computer to preform operations to affect temperature comprising:

defining a desired temperature as a first value;

activating a HVAC device if a current temperature achieves a first condition relative to the desired temperature;

deactivating the HVAC device if the current temperature achieves a second condition relative to the desired temperature;

defining the desired temperature as a second value if the current temperature does not achieve the second condition within a first time period, wherein defining the desired temperature as the second value includes using the current temperature at the end of the first time period in a calculation to determine the second value.

9. The non-transitory computer readable medium of claim 8 , wherein the calculation to determine the second value is: second value=(/first condition/+/second condition/)/2+current temperature at the end of the first time period.

10. A non-transitory computer readable medium having instructions thereon, wherein the instructions when executed by a computer cause the computer to preform operations to affect temperature comprising:

defining a desired temperature as a first value;

activating a HVAC device if a current temperature achieves a first condition relative to the desired temperature;

deactivating the HVAC device if the current temperature achieves a second condition relative to the desired temperature;

defining the desired temperature as a second value if the current temperature does not achieve the second condition within a first time period; and

after defining the desired temperature as the second value, if the current temperature achieves a third condition relative to the desired temperature within a third time period, defining the desired temperature as a fourth value, wherein the third condition is equal to the second condition and the fourth value is equal to the first value.

11. A method of controlling a HVAC system including the steps of:

obtaining a first temperature value;

defining a desired temperature as the first temperature value;

activating the HVAC device if a current temperature achieves a first condition relative to the desired temperature;

deactivating the HVAC device if the current temperature achieves a second condition relative to the desired temperature;

defining the desired temperature as a second value and deactivating the HVAC device if the current temperature does not achieve the second condition within a first time period.

12. The method of claim 11 , the steps further comprising: after defining the desired temperature as the second value, if the current temperature does not achieve a third condition within a second time period, defining the desired temperature as a third value.

13. The method of claim 11 , the steps further comprising: after defining the desired temperature as the second value, if the current temperature achieves a third condition relative to the desired temperature within a third time period, defining the desired temperature as a fourth value.

14. The method of claim 11 , wherein the first condition is four degrees warmer in a cooling mode and is four degrees cooler in a heating mode.

15. The method of claim 11 , wherein the second condition is two degrees cooler in a cooling mode and is two degrees warmer in a heating mode.

16. The method of claim 11 , the steps further comprising: determining information regarding a sleep status of an individual located within the area affected by the HVAC device.

17. The method of claim 16 , the steps further comprising: adjusting the desired temperature by considering the information regarding sleep status of the individual.

18. A method of controlling a HVAC system including the steps of:

obtaining a first temperature value;

defining a desired temperature as the first temperature value;

activating the HVAC device if a current temperature achieves a first condition relative to the desired temperature;

deactivating the HVAC device if the current temperature achieves a second condition relative to the desired temperature;

defining the desired temperature as a second value if the current temperature does not achieve the second condition within a first time period, wherein the step of defining the desired temperature as the second value includes using the current temperature at the end of the first time period in a calculation to determine the second value.

19. The method of claim 18 , wherein the calculation to determine the second value is: second value=(/first condition/+/second condition/)/2+current temperature at the end of the first time period.

20. A method of controlling a HVAC system including the steps of:

obtaining a first temperature value;

defining a desired temperature as the first temperature value;

activating the HVAC device if a current temperature achieves a first condition relative to the desired temperature;

deactivating the HVAC device if the current temperature achieves a second condition relative to the desired temperature;

defining the desired temperature as a second value if the current temperature does not achieve the second condition within a first time period; and

after defining the desired temperature as the second value, if the current temperature achieves a third condition relative to the desired temperature within a third time period, defining the desired temperature as a fourth value, wherein the third condition is equal to the second condition and the fourth value is equal to the first value.
