Abstract
An extended run time device for extending the time that a compressor-based heating, ventilating, and air-conditioning (HVAC) system runs so as to increase energy efficiency of the HVAC system. The extended run time device includes a sensing circuit, a switching device and a processor. Based upon a signal from the sensing circuit, the processor causes the switching device to transmit a proxy control signal to the compressor, thereby causing power to the compressor to be maintained for a time period longer than a time period requested by the temperature control device.
