Abstract
A remote control for operating a combination ceiling fan and light fixture features a dual microprocessor control. A microprocessor mounted in the remote control includes a clock and may be programmed to operate the ceiling fan and/or light fixture in a timed manner. A microprocessor mounted in the ceiling fan controls fan speed, fan direction, and light intensity. The two microprocessors communicate over the 60 Hz power line between the remote control and the ceiling fan. The remote control features a control panel for inputting commands from the user, as well as a display for displaying fan and light status as well as time. One feature of the display are animated fan and light displays. The animated fan display appears to rotate in the same direction as the ceiling fan and may also indicate fan speed. The animated light display depicts a light bulb with a series of flashing rays emanating therefrom. The remote control connects in series with the load line of the ceiling fan and features a power supply which provides power for the remote control from the voltage drop of a triac in series with the ceiling fan load line.
