ABSTRACT:
A remote control for operating a combination ceiling fan and light fixture features a system for communicating command signals to a fan mounted controls over an existing load line. A remote control features two switches for control of a ceiling fan and associated light fixture. Each switch connects a different Zener diode into the load line to produce a fixed predetermined voltage drop. A control mounted in the ceiling fan detects these voltage drops and controls fan speed and light intensity accordingly. The remote control and the fan mounted control communicate over the 60 Hz power line between the remote control and the ceiling fan. The remote control connects in series with the load line of the ceiling fan.
