Patent ID: 8571719

Claim:
A load control system for use in a building having a heating and cooling system and a window located in a space of the building, the load control system comprising: a temperature control device for controlling a setpoint temperature of the heating and cooling system to thus control a present temperature in the building; and a motorized window treatment for controlling a window treatment covering to an initial position between a fully open position in which the window is not covered and a fully-closed position in which the window is covered; wherein after the motorized window treatment moves the covering in a first direction from the initial position towards the fully open position to allow more sunlight to enter the space when the heating and cooling system is heating the building, the load control system determines if the heating and cooling system is consuming more energy than when the covering was in the initial position; and wherein if the heating and cooling system is consuming more energy than when the covering was in the initial position, the motorized window treatment moves the covering in a second direction towards the fully-closed position.
