AbstractA load management control system is provided for an air conditioner. The system includes an outdoor temperature sensor for sensing outdoor temperature of the outside of an enclosure to be air-conditioned and an indoor temperature sensor for sensing an indoor temperature of the enclosure. A device is provided for determining a difference in output of the indoor and outdoor temperature sensors. A device is provided for comparing the difference in output of the indoor and outdoor temperature sensors with a reference input. The system further includes a device for detecting an external controlling signal from an input device coupled to the system. A control device is provided for controlling an air conditioner control circuit based upon input from the comparing device and the detecting device. When an allowable temperature differential is exceeded, the controlling device opens at least one contact to interrupt the air conditioner control circuit so as to reduce electrical load. The controlling device closes the contact to restore the operation of the air conditioner control circuit when the temperature differential is no longer exceeded.
