Abstract
Disclosed is a system and method for power line control of electrical fans. The system generates a sinusoidal wave using a crystal oscillator. Control information is added to the sinusoidal wave by routing the wave through a phase inversion circuit a predetermined intervals according to a protocol. The resulting control signal is sent on a power line. The control signal is received using a crystal filter, decoded and converted to executable instructions for controlling a fan motor.
