Abstract: Control apparatus for the automatic opening and closing of electrically operated dampers installed in home central heating and air conditioning ducts to control air flow to a plurality of rooms for the expressed purpose of energy conservation. A programmable timer is provided for adapting the control apparatus to the life styles of the user. Manually operable switches are also provided to allow for unscheduled events requiring temporary deviation from damper program for a given room, and to allow for constant bypass of the damper program leaving damper in the fully open or fully closed position. Utilizing this apparatus to greatly reduce air flow to unoccupied rooms, thereby, reducing volume of home air conditioned or heated space on a scheduled basis, will achieve energy conservation, thereby fulfilling the intentions of this invention.
