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.

Claims

1. A programmable circuit controller connected to a source of AC power for controlling a plurality of AC lighting circuits, comprising:

(a) level adjustment switch means for controlling the levels of AC power provided to each of said AC lighting circuits, respectively;

(b) learn switch means for storing signals representing power levels established by said level adjustment switch means in a memory;

(c) preset switch means for designating a plurality of power levels established by said level adjustment switch means to be stored in a memory as a predetermined set when said preset switch means is actuated simultaneously with the actuation of said learn switch means; and

(d) wherein said preset switch means comprises a plurality of switches, each switch representing one predetermined set of lighting levels to be recalled from said memory and established as current lighting levels when one of said switches is actuated independently of said learn switch means.

2. The programmable circuit controller of claim 1 further including automatic fade control means for fading from one lighting level to a next lighting level.

3. The programmable circuit controller of claim 1, further including microprocessor means for periodically interrogating the states of said level adjustment switch means, said learn switch means, and said preset switch means, and for initiating AC lighting circuit control functions based upon the said states of said switches.

4. The programmable circuit controller of claim 3 wherein said microprocessor means includes a timer responsive to an AC power input waveform for periodically causing said microprocessor to compare the instantaneous phase angle of said waveform to a signal stored in a memory for each of said AC lighting circuits, and for turning on each respective one of said AC lighting circuits when said signal corresponds to said phase angle.

5. The programmable circuit controller of claim 4 wherein said microprocessor means senses the zero crossing of said AC power waveform and includes a program for sensing the input states of said level adjustment switch means, said learn switch means, and said preset switch means, said program being operative during a period of time immediately preceding to immediately following said zero crossing.

6. A programmable circuit controller connected to a source of AC power for controlling a plurality of AC lighting circuits comprising:

(a) a control panel including a plurality of input switches; and

(b) a microprocessor responsive to a predetermined combination of signals from certain ones of said input switches for designating one or more of said AC lighting circuits as fluorescent lighting circuits, and for designating one other of said AC lighting circuits as a heating circuit, and storing said designations in a memory, such that whenever at least one of said fluorescent lighting circuits is turned on, said heater circuit is automatically turned on at full power.

7. The programmable circuit controller of claim 6 wherein said control panel includes a plurality of preset switches for establishing preset lighting levels for each of said AC lighting circuits.

8. The programmable circuit controller of claim 7 wherein said control panel further includes a plurality of level adjustment switches for establishing the levels of light intensity in each of said AC lighting circuits.

9. The programmable circuit controller of claim 7, further including an off switch for providing one of said signals in said predetermined combination of signals when said off switch is actuated simultaneously with one of said preset switches.
