ABSTRACT An apparatus for connecting and disconnecting appliances to an electrical supply, responsive to door activated switch means. A transmitter responds to entrance into a room by causing a receiver to active a connecting means supplying an appliance with electrical energy. Upon closure of the door, a deadbolt must be engaged within the room within a predetermined period to maintain the appliances in their energized states. Release of the deadbolt to exit from the room causes the transmitter to enter a delay sequence thereby providing an occupant with sufficient time to exit prior to de- energizing the appliances. Subsequent thereto, A signal is transmitted to the receiver for shutdown of the appli- ances. An overrideing thermostat is provided to control heating and cooling appliances responsive to the trans- mitter, the thermostat having a broader thermal zone of operation than a typical thermostat controlling the heating and cooling appliances in the presence of the room occupant. An occupant-activated switch is provided to override the deadbolt and control the transmitter under certain circumstances.
