Abstract

A system for controlling electrical energy consumption according to a user-set kilowatt limit and an automatic kilowatt limit calculated in a microprocessor. Power is limited by regulating an electric hot water heater according to a preset program and, if necessary, by lowering room temperatures due to electric heater cut back. The device features a computer-controlled display and simplified keyboard which permits the user to enter only valid data. The device also features program fail, power fail, and static detect circuitry to prevent computer error.
