See as figure 12-15, the controller includes the step-down rectifier circuit, time-based pulse generator, frequency distributor, high-speed starting timing circuit, wind switching circuit and controllable trigger circuit. The most noticeable character of this controller is that its rotating speed changes with the working time. When it is starting, the fan runs at a high speed, and it switches into the analog natural wind mode automatically in dozens of seconds. And the circuit can also used as a timed stepless governor. Besides, the circuit can also be used as the light adjuster, temperature controller, timer and so on of lamps and electric appliances, after it is adjusted.
