In the figure is the simple constant temperature control circuit, this controller consists of the step-down rectifier circuit, temperature sensor and RS trigger control circuit and so on. The step-down rectifier circuit power supply circuit outputs the +6v voltage. The temperature sensors of Rt1 and Rt2 is modified from a sun light lamp starter, of which Rt1 controls the lower limit value while Rt2 controls the upper limit value of the temperature, and the thermometer is used to adjust the interval. When the power is on, due to the LEV on 5-pin and 6-pin but the high LEV of 3-pin, the dual-way SCR is triggered and conducting.
