ABSTRACT:
A system for programmable controlling the output level of at least one load, utilizes an isolated receiver-controller located adjacent to the load and receiving control data from at least one transmitter, which may be at a location remote from the load location. The transmitted data includes an address portion, identifying that particular one of a plurality of loads having the corresponding local address, and a command data portion, establishing both the on/off condition and the output level of the addressed load. Local control may be temporarily substituted for remote control. The output level is controlled by programmably varying the magnitude of an impedance coupled to a pair of load input terminals.
