System and method for establishing local control of a space conditioning load during a direct load control event
First Claim
1. A method for establishing local control of a space conditioning load during a direct load control event having a duration and issued by a utility provider, comprising:
- during said duration, a load control logic determining that a temperature threshold value is reached, in response to said determination, the load control logic automatically and completely disabling direct load control of the space conditioning load from the utility provider,setting a new temperature set point of a thermostat to the temperature threshold value, and automatically transitioning control to a temperature setback method of the thermostat;
performing a temperature setback method of the thermostat until said load control logic determines that a timer associated with said duration expired; and
in response to said determining that the timer expired, the load control logic determines that said duration expired, andchanges the new temperature set point of the thermostat back to a desired temperature set point.

Abstract
A system for establishing local control of a space conditioning load includes a switch for controlling a flow of energy for a space conditioning load. Control logic is operatively coupled to the switch, for receiving control parameters associated with a direct load control event from a utility provider. The control logic may also measure room temperature based on received temperature signals and determine if a room temperature is greater a comfort temperature range. The control logic may eliminate operation of a direct load control program if the room temperature is greater than or equal to the comfort temperature range. The control logic may log and signal back to the utility provider that the comfort temperature range is exceeded. The control logic may then restore local control of the switch and initiate a temperature setback control to a thermostat for the remainder of the control period.

9. A system for establishing local control of a space conditioning load during a direct load control event having a duration and issued by a utility provider, comprising:
-
means for automatically eliminating direct load control of the space conditioning load from the utility provider, when a load control logic determines that a temperature threshold value is reached during said duration and in response to said determination; the load control logic setting a new temperature set point of a thermostat to the temperature threshold value for a temperature setback method of the thermostat; and means for automatically transitioning to the temperature setback method of the thermostat, the temperature setback method of the thermostat is performed with the new set point temperature until said load control logic determines that a timer associated with said duration has expired and then changes the new temperature set point of the thermostat back to a desired temperature set point. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A system for establishing local control of a space conditioning load, comprising:
-
load control logic comprising at least one of hardware and a non-transitory computer usable medium having a computer readable program code embodied therein for automatically determining if a temperature threshold is reached during said duration and in response to said duration, and for automatically eliminating operation of a direct load control program associated with one or more control parameters, when the temperature threshold is reached during a direct load control event; and the load control logic setting a new temperature set point of a thermostat to the temperature threshold, and for automatically transitioning control to a temperature setback method of the thermostat by restoring control to a switch, the temperature setback method of the thermostat is performed with a new temperature set point until said load control logic determines that a timer associated with said duration has expired and then changes the new temperature set point of the thermostat back to a desired temperature set point. - View Dependent Claims (19, 20)
