Abstract:
The efficient fan controller includes a microprocessor receiving at least one signal input from thermostat/equipment control terminals to control a fan relay to operate a system fan. The microprocessor monitors a thermostat call for cooling/heating duration and determines a variable fan-off delay based on the cooling/heating cycle duration, and at an end of a cooling/heating cycle energize the fan relay to operate the system fan for the variable fan-off delay. The fan controller avoids false thermostat activation signals and includes a common wire adapter to provide continuous power to a smart communicating thermostat and is configured to evaluate floating, zero, rectified, false positive and active input signals. The fan controller can be embodied on a forced-air-unit control board or thermostat. The fan controller installation methods ensure the system fan/blower operates at high speed for heating and cooling to improve thermal comfort, efficiency and satisfy the thermostat sooner to save energy.

Claim (Index 3):
The fan controller of  claim 1 , wherein the microprocessor ( 304 ) is configured to determine at least one signal on the output ( 808 ) from the thermostat element  806  of the common wire adapter ( 815 ) terminal from the group consisting of: a floating signal, a zero voltage signal, a false positive stray voltage signal, an active voltage signal ( 350 ), and the positively rectified signal ( 351 ); the microprocessor is further configured to recognize the floating signal, the zero voltage signal, the false positive stray voltage signal, the active voltage signal, and the positively rectified signal and only provide a low voltage control signal to the fan control output  212  to control the system fan/blower ( 206 ) when the input signal ( 808 ) has at least an active positively rectified voltage signal.
