Abstract

PURPOSE: To start a conduction for the heating load after a completion of the timer operation, in such manner that, with a power feed stopped to the heater after an arrival of the heated unit temperature at the set value, thereafrer with the heated substance temperature lowering by a specified differential width, the timer be operated.
CONSTITUTION: By the signal of a temperature sensor 7, is given a trigger signal to a thyristor 47 from a control circuit 41, with the conduction controlled of a heater 48. When with a switch 10 closed for operating the hysteresis control, a hysteresis control logic unit H stops the operation of a two-bit divider unit D for a prescribed length of period, with a triggering ceased for the thyristor 47 to add a temperature swing of the heater. At this time, with a counter I made counting the power source frequency for a prescribed length of time, after a lowering of the heated substance temperature by a specified differential width, a reset signal is given to the logic circuit H from a reset unit A, to again trigger the thyristor 47.
