  • Patent number: 6650029
    Abstract: A control apparatus for a light includes a control unit and a plurality of remote control devices. The control unit changes the state of the light, either when a conventional wall switch is actuated or when a control signal is received from one of the remote control devices, which allows the light to be controlled from a further point without the need to run additional wires down a wall to an additional switch. Each remote control device can transmit a signal to put the control unit into an ERASE mode, upon which the address codes of all remote control devices are erased from its memory, with the exception of the address code of the control device which gave the command to enter the “erase” mode. In this manner, the control unit can be re-configured remotely to respond solely to the control device which gave-the command to the control unit.
