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 2):
The fan controller of  claim 1 , wherein the electrical inputs to the fan controller have at least one zener diode between the electrical input signal and an optoisolator to eliminate false positive stray voltage signals and establish a minimum threshold active voltage signal to deliver to the microprocessor as an active control signal.
