Abstract

A system and method are presented for managing the supply of energy to heating and cooling devices to reduce the thermal flux and overshoot in buildings having heating and cooling devices that are sized for extreme temperature demands, but which operate inefficiently for moderate conditions. The system interposes a control module between sensor devices and heating or cooling devices, to filter the signals from the sensor devices calling for heating or cooling according to one or more on/off routines. The control module defers the sending of signals activating or deactivating heating or cooling devices, thus allowing for moderating of ambient conditions between the initial demand from the sensor devices and the supply of heating or cooling by the heating or cooling devices.

Claims

1. A method for controlling heating or cooling calls from a thermostat to one or more heating or cooling devices, said method comprising the steps of:

storing a plurality of sequential routines, each routine comprising a plurality of sequential time intervals and a corresponding on or off state for each time interval, wherein a sum of the plurality of sequential time intervals for each routine comprises a total routine time interval;

in response to receiving a heating or cooling call from the thermostat, executing a designated current routine from a beginning point, wherein executing the designated current routine comprises (a) sending a heating or cooling activation signal to the one or more heating or cooling devices if a current time interval of the designated current routine comprises an on state or (b) not sending a heating or cooling activation signal to the one or more heating or cooling devices if the current time interval of the designated current routine comprises an off state;

if the heating or cooling call received from the thermostat terminates before the total routine time interval lapses, stopping execution of the designated current routine and waiting for a subsequent heating or cooling call to be received from the thermostat before again executing the designated current routine from the beginning point;

if the heating or cooling call from the thermostat continues uninterrupted for the total routine time interval, designating a different routine as the designated current routine and executing the newly designated current routine from a beginning point, the different routine being along the sequential routines in a first direction from the previously designated current routine; and

if no heating or cooling call is received from the thermostat continues for the total routine time interval, designating a different routine as the designated current routine and executing the newly designated current routine from a beginning point, the different routine being along the sequential routines in a second direction from the previously designated current routine, the second direction being opposite the first direction.

2. The method of claim 1, wherein the total routine time intervals for each of the plurality of routines are equal.

3. The method of claim 1, further comprising designating one of the plurality of sequential routines as a starting routine.

4. The method of claim 1, wherein, if the heating or cooling call from the thermostat continues uninterrupted for the total routine time interval, the different routine being designated as the current routine is along the sequential routines in a first direction from the previously designated current routine and immediately adjacent the previously designated current routine.

5. The method of claim 1, wherein, if no heating or cooling call is received from the thermostat continues for the total routine time interval, the different routine being designated as the current routine is along the sequential routines in a second direction from the previously designated current routine and immediately adjacent the previously designated current routine.

6. The method of claim 1, wherein, if no heating or cooling call is received from the thermostat for a predefined extended time period, then any subsequent heating or cooling calls will be allowed to pass unimpeded to the one or more heating or cooling devices until a preset temperature is reached.

7. A method for controlling heating or cooling calls from a thermostat to one or more heating or cooling devices, said method comprising the steps of:

storing a plurality of sequential routines, each routine comprising a plurality of sequential time intervals and a corresponding on or off state for each time interval, wherein a sum of the plurality of sequential time intervals for each routine comprises a total routine time interval;

in response to receiving a heating or cooling call from the thermostat, executing a designated current routine from a beginning point, wherein executing the designated current routine comprises allowing or blocking the received heating or cooling call based on the on or off state specified in a current time interval of the designated current routine;

if the heating or cooling call received from the thermostat terminates before the total routine time interval lapses, stopping execution of the designated current routine and waiting for a subsequent heating or cooling call to be received from the thermostat before again executing the designated current routine from the beginning point;

if the heating or cooling call from the thermostat continues uninterrupted for the total routine time interval, designating a different routine as the designated current routine and executing the newly designated current routine from a beginning point, the different routine being along the sequential routines in a first direction from the previously designated current routine; and

if no heating or cooling call is received from the thermostat continues for the total routine time interval, designating a different routine as the designated current routine and executing the newly designated current routine from a beginning point, the different routine being along the sequential routines in a second direction from the previously designated current routine, the second direction being opposite the first direction.

8. The method of claim 7, wherein the total routine time intervals for each of the plurality of routines are equal.

9. The method of claim 7, further comprising designating one of the plurality of sequential routines as a starting routine.

10. The method of claim 7, wherein, if the heating or cooling call from the thermostat continues uninterrupted for the total routine time interval, the different routine being designated as the current routine is along the sequential routines in a first direction from the previously designated current routine and immediately adjacent the previously designated current routine.

11. The method of claim 7, wherein, if no heating or cooling call is received from the thermostat continues for the total routine time interval, the different routine being designated as the current routine is along the sequential routines in a second direction from the previously designated current routine and immediately adjacent the previously designated current routine.

12. The method of claim 7, wherein, if no heating or cooling call is received from the thermostat for a predefined extended time period, then any subsequent heating or cooling calls will be allowed to pass unimpeded to the one or more heating or cooling devices until a preset temperature is reached.

13. A device for controlling heating or cooling calls from a thermostat to one or more heating or cooling devices, said device comprising:
