ABSTRACT:
A lighting control system operates to control multiple zones of lighting through multiple dimming circuits so as to achieve any one of several desired lighting scenes. The system includes a plurality of wallbox control units which collectively operate to multiplex digital lighting control information on a communications link. Each wallbox control unit includes a plurality of zone-intensity actuators which are manipulatable to alter the information transmitted by their respective wallbox control so as to vary the lighting intensity of an associated lighting zone. A central lighting control panel includes a microprocessor adapted to receive and processes the multiplexed information transmitted on the link, and re-transmit digital lighting control information, on a second multiplex link, to the dimming circuits. According to one aspect of the invention, the microprocessor is programmed to assign a preselected dimming circuit to any one of the zone-intensity actuators when that actuator is manipulated according to a predetermined sequence.
