Abstract

A time of day zoning control system for a heating, ventilating, and air conditioning system is provided. The system utilizes a programmable thermostat and a number of temperature sensors to control the HVAC system to regulate the temperature in a particular location within a dwelling or structure based on consumer preferences. The regulation control will utilize a temperature sensed by a particular temperature sensor at different times throughout the day to control the temperature in that zone to ensure occupant comfort. A single temperature sensor may be selected to control the HVAC system during these different periods, or multiple sensors may be utilized during the same period. When multiple sensors are used, a weighting factor may be used.

Claims

1. A heating, ventilating and air conditioning (HVAC) system control system, comprising:

a programmable thermostat;

at least two temperature sensors in communication with the thermostat, at least one of the at least two temperature sensors adapted to be located remotely from the thermostat; and

wherein the thermostat is programmable to control the HVAC system based on a first temperature sensed by one of the at least two temperature sensors during a first period of a day and based on a second temperature sensed by another of the at least two temperature sensors during a second period of the day.

2. The control system of claim 1, wherein one of the at least two temperature sensors is located within the thermostat.

3. The control system of claim 1, wherein at least one of the at least two temperature sensors are in wireless communication with the thermostat.

4. The control system of claim 1, wherein the thermostat is programmable to control the HVAC system based on an average of the first temperature sensed by one of the at least two temperature sensors and the second temperature sensed by another of the at least two temperature sensors at a third period of the day.

5. The control system of claim 1, wherein the thermostat is programmed to control the HVAC system based on a weighted average of the first temperature sensed by one of the at least two temperature sensors and the second temperature sensed by another of the at least two temperature sensors at a third period of the day.

6. The control system of claim 1, wherein the thermostat comprises:

a user display screen;

a user function selection means for inputting a user selection associated with a function indicated on the user display screen;

a user scrolling means for allowing a user to scroll among available items and parameters; and

wherein the thermostat displays a select sensor screen on the user display, the select sensor screen providing a program selection allowing a user to program which of the at least two sensors are to be used by the thermostat to control the HVAC system during different periods of the day.

7. The control system of claim 6, wherein the thermostat displays a select program days screen on the user display, the select program days screen providing user selectable options for groupings of days and individual days for which programming will be effective.

8. The control system of claim 7, wherein the thermostat displays a programming screen for a selected grouping of days or a selected individual day having a plurality of events displayed thereon, and wherein the programming screen allows a user to change which of the at least two sensors are used by the thermostat to control the HVAC system during each of the plurality of events.

9. The control system of claim 8, wherein the thermostat displays a schedule menu from which a user can change how many events are available for control of the HVAC system.

10. A method of enhancing occupant comfort in a multi-zonal dwelling having a single thermostat to control temperature regulating equipment therefore, comprising the steps of:

sensing a first temperature in a first area of the dwelling during a first period;

regulating the first temperature of the first area during the first period based on the step of sensing the first temperature in the first area;

sensing a second temperature in a second area of the dwelling during a second period; and

regulating the second temperature of the second area during the second period based on the step of sensing the second temperature in the second area.

11. The method of claim 10, further comprising the steps of:

sensing the first temperature in the first area and the second temperature in the second area during a third period; and

regulating the temperature in the first area and in the second area based on an average of the first temperature and the second temperature.

12. The method of claim 11, further comprising the step of applying a first weighting factor to the first temperature and a second weighting factor to the second temperature, and wherein the step of regulating the temperature in the first area and in the second area based on an average of the first temperature and the second temperature comprises the step of regulating the temperature in the first area and in the second area based on a weighted average of the first temperature and the second temperature.

13. The method of claim 10, further comprising the steps of:

selecting one of the first temperature and the second temperature to be sensed during the first period based on probable occupancy of the first area and the second area during the first period; and

selecting one of the first temperature and the second temperature to be sensed during the second period based on probable occupancy of the first area and the second area during the second period.

14. The method of claim 10, further comprising the steps of:

sensing one of the first temperature or the second temperature during a third period; and

regulating the sensed one of the first temperature or the second temperature during the third period.

15. A time of day climate control method of controlling temperature regulating equipment in a multi-room structure to enhance occupant satisfaction, comprising the steps of:

receiving a first user programming input to select a first area of the structure from which to sense temperature during a first period;

receiving a second user programming input to select a second area of the structure from which to sense temperature during a second period; and

controlling the temperature regulating equipment during the first and the second periods in accordance with the first and the second user programming inputs.

16. The method of claim 15, further comprising the step of displaying a select sensor screen having user selectable options for selection of temperature sensors in the first and the second area of the structure allowing a user to program which of the sensors are to be used to control the temperature regulating equipment during different periods of the day.

17. The method of claim 16, further comprising the step of displaying a select program days screen having user selectable options for groupings of days and individual days for which programming will be effective.

18. The method of claim 17, further comprising the step of displaying a programming screen for a selected grouping of days or a selected individual day having a plurality of user selectable events displayed thereon allowing a user to program which of the sensors are to be used to control the temperature regulating equipment during each of the plurality of events.

19. The method of claim 18, further comprising the step of displaying a schedule menu from which a user can change how many events are available for control of the temperature regulating equipment during a day.

20. The method of claim 15, further comprising the steps of:

receiving a third user programming input to select a third area of the structure from which to sense temperature during a third period;

receiving a fourth user programming input to select a fourth area of the structure from which to sense temperature during a fourth period; and
