Title CURRENT MONITORING CONTROL FOR ELECTRICALLY POWERED DEVICES Inventors James F. Saunders Robert E. Krocker Apparatus and method for controlling one or more electrically powered devices. A control for a temperature conditioning system is shown which is operative to monitor the electrical current supplied to component devices, i.e., compressors, auxiliary heating elements, indoor fan, and outdoor fan; and to cause an indicator means to indicate that one or more of the devices has failed to operate in a manner consistent with the controlled status of the system.
