Abstract

PURPOSE:To easily change over a set temperature, by providing a level converting circuit fo shifting by a constant value an output level of a temperature detecting circuit or a temperature setting circuit, in accordance with operation of a switch. CONSTITUTION:A temperature of heater load is detected by a temperature detecting circuit 17 consisting of a sensor 3, a detecting electrode line 4, a transistor 21, etc., and is connected to a nonreversing terminal of a voltage comparator 45. To a reversing terminal is connected an output of a temperature setting circuit 28, a thyristor 48 is made to conduct in accordance with size of both signals, and the power is supplied to a heater 2. On the temperature setting circuit 28 is provided a forward phase amplifier 29 which has connected a constant voltage circuit to a reversing input terminal, and a temperature set point is shifted by a constnt value by turning on and off switches 39, 43.
