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.

1. 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 comprising: a temperature control device configured to generate a call-for-cool control signal having a first logic state for the duration of a requested compressor run time, the call-for-cool control signal having a second logic state after the requested compressor run time has elapsed;a power supply configured to generate a proxy call-for-cool control signal that is set to the first logic state irrespective of the requested compressor run time;a compressor time-extending switching device having: a first terminal including means for electrically connecting to a control circuit that controls electrical power to a compressor of the HVAC system when the first terminal is at the first logic state;a second terminal including means for receiving the call-for-cool control signal from the temperature control device, anda third terminal including means for receiving a proxy call-for-cool control signal from the power supply,the compressor time-extending switching device configured to extend an individual compressor run time when a requested compressor run time period is less than a predetermined minimum compressor run time period by selectively disconnecting the first terminal from the second terminal and connecting the first terminal to the third terminal, thereby causing the control circuit to receive the first logic state of the proxy call-for-cool control signal and extending the compressor run time irrespective of the logic state of the call-for-cool control signal. 2. The extended run-time device of claim 1, wherein the temperature control device comprises a thermostat. 3. The extended run-time device of claim 1, further comprising a sensing circuit including means for receiving the call-for-cool control signal and to output a sense signal, wherein the sensing circuit samples the call-for-cool control signal at a predetermined sampling frequency to detect the presence or absence of the first logic state or the second logic state. 4. The extended run-time device of claim 1, wherein the call-for-cool control signal comprises a 24VAC control signal in the first logic state. 5. The extended run-time device of claim 3, wherein the sensing circuit comprises a Schmitt trigger sense circuit. 6. The extended run-time device of claim 1, wherein the compressor time-extending switching device comprises a relay. 7. The extended run-time device of claim 1 further comprising a processor in electrical communication with the sensing circuit and the compressor time-extending switching device, the processor including means for receiving the sense signal from the sensing circuit, determining a requested compressor run time period based upon a call-for-cool control signal, and transmitting a switching control signal to the compressor time-extending switching device, thereby controlling the compressor time-extending switching device to extend the individual compressor run time, wherein the processor is further configured to determine whether the requested compressor run time period is less than the predetermined minimum individual compressor run time period, and to transmit the switching control signal to the compressor time-extending switching device when the compressor run time period is less than the predetermined minimum compressor run time period. 8. The extended run-time device of claim 1, wherein the extended individual compressor run time period is substantially equal to the minimum compressor run-time period less the requested compressor run time period. 9. The extended run-time device of claim 1, wherein the extended individual compressor run time period is a multiple of the requested run time period. 10. The extended run-time device of claim 1, further comprising a fan time-extending switching device in electrical communication with the temperature control device, a circulation fan, and a processor. 11. The extended run-time device of claim 10, wherein the processor controls the fan time-extending switching device so as to extend a requested call-for-fan time period from the temperature control device, thereby causing the circulation fan to continue to run after an expiration of the requested call-for-fan time period. 12. The extended run-time device of claim 10, wherein the control circuit comprises a cooling contactor. 13. The extended run-time device of claim 1, wherein the extended run-time device is integrated into a load-control switch. 14. The extended run-time device of claim 1, wherein the extended run-time device is integrated into a fan-control board of a forced air unit.
