The chart shows the high gear stepping dimmer controller circuit, which has the following functions: It has four gears of stong, medium, weak, extinguish to control the timing of light E1 in 1h, 2h , 4h and 8h; On the other hand, it can control a way of wall lights being in on and off state and another way of fluorescent lights in working state. The device in the core of the circuit is a BA3102 fan control ASIC, and it has three wind-speed control of strong, medium and weak; it has 8h four-stage non-progressive electronic timing(1,2,4,8 h); it has two non-independent control outputs.
