Abstract
Apparatus which can control a remotely-located electric storage heater from a central location without requiring control wires between the central location and the remote location is disclosed. Control signals indicating the heating cycle and representative of the outside ambient temperature are generated by apparatus at the central location and encoded by high-frequency signals which are superimposed on the normal power line voltage. At remote locations each electric storage heater is equipped with a receiver unit which decodes the high frequency control signals superimposed on the power line. The receiver unit then operates a solid state relay to convert the coded signals into the normal control signals which operate the heater.
