ABSTRACT:
The invention is a remotely controlled ceiling fan and light assembly. Control of the assembly is accomplished by a transmitter (22) having a motor control button (26) and a light control button (24) to be depressed to control the fan (14) and light (18) on the assembly respectively. The motor control button (26) may be depressed for an extended time to reverse the direction of the fan (14). The transmitter (22) transmits a digitally coded radio signal wherein the coding is consumer selectable through switches. The receiver (20) on the fan and light assembly decodes (44) the pulses to ensure proper detection thereof. The eighth pulse of the radio coded signals indicates whether motor (16) or light (18) control is required. The receiver (20) includes a light control circuit (58) and motor control circuit (60) responsive to the decoded signal to control illumination of the light (18) and rotational speed and direction of the motor (16), respectively.
