Abstract
A variable speed control system is provided for use with a heat pump heating/cooling system having a variable speed compressor. The control system includes a remote transceiver, a second transceiver to communicate with the first transceiver, and an AC power module to communicate with the second transceiver. The AC power module further includes multiple current limiting devices and multiple temperature sensors and varies the output of the variable speed compressor by comparing the readings from the temperature sensors to a pre-determined temperature setting.
