Abstract

A programmable lighting circuit controller for controlling a plurality of household lighting circuits includes a microprocessor and an electronically erasable programmable read only memory for programming the household lighting circuits for a variety of loads. The lighting circuits may be configured as a combination of incandescent and fluorescent loads by designating one output of the controller as a heater circuit for any of the fluorescent loads. The microprocessor is controlled by a set of nonlatching pushbuttons on a front panel which raise and lower lighting levels, set lighting levels in memory and recall preset levels from memory. Combination of two pushbuttons simultaneously pushed may initiate special programming features such as heater designation of one channel for fluorescent lighting.
