ABSTRACT:
The disclosure relates to a system for providing central control for appliances connected to the electrical power distribution network of a building. In one embodiment the systems may be used for conserving energy used by temperature regulating units, such as space heaters and air conditioning units, by overriding local thermostatic control therefor, to prevent operation of the units during preselected time periods. The system includes a transmitter for transmitting control pulses over the electrical power distribution network of the building. Receivers, connected to the local thermostatic controls, detect the pulses and shut off the electrical power provided to the thermostatic controls responsive to the detected pulses to thereby prevent operation of the associated temperature regulating units. In one embodiment the control pulse transmitter operates responsively to signals transmitted over a coaxial cable such as employed in cable television systems.
