ABSTRACT:
A remote control circuit for a hard wired remote control controlling multiple functions in a multiple motor device has a reduced number of wires extending between the hand held control and the motor control circuit. The circuit includes a rectifier for generating a positive control voltage and a negative control voltage which are separately supplied along individual wires to the hand held control, and a single wire extending between the hand held control and the control circuit for each function, the voltage appearing along the wire designating the direction of movement of the function. A pair of parallel connected LEDs sense the polarity of the voltage and energize a triac corresponding to the polarity of the voltage appearing along the control wire to energize the proper winding of a reversible motor.
