Abstract
A control system for remotely controlling the application of electric power to a plurality of electric apparatuses includes a radio transmitting device at a central location, and a radio receiving device and a control unit at each electrical apparatus location. Programming signals designating the operating protocol or mode and the location of the electrical apparatus are transmitted by a radio programming signal to the control unit associated with each electrical apparatus. Subsequently, timing reference signals are transmitted to the control units of all electrical apparatus. Each control unit interprets and responds to the timing signals in accordance with previously received programming signals to control the application of electric power to the electrical apparatus in accordance with a predetermined operating protocol.
