The temperature controller circuit is composed of the power supply circuit, temperature detection circuit, reference voltage circuit, temperature indicator circuit, voltage comparator amplifier and control implementation circuit, and it is shown as the chart. Power supply circuit is composed of the power switch S, power transformer T, bridge rectifier UR, filter capacitors C1, C2, three-terminal voltage regulator integrated circuit IC2, current limiting resistor RIO and power indicator LED VL1. Temperature detection circuit consists of the transistor temperature sensor V1, resistor R1, capacitor C3 and N1 which is inside of the operational amplifier integrated circuit IC1 (N1 ~ N4).
