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.
