Abstract

PURPOSE: To provide a high-scale operation for a constant length of period, further with a proportional operation of temperature forcibly operated, when setting to the high-scale control position even if the heating unit is in an operation of hysteresis temperature control.
CONSTITUTION: The signal of a temperature sensor 7 is given to a control circuit 41, with a trigger signal fed to a thyristor 47 from the control circuit to control the conduction of a heater 48. With a switch 10 closed, a hysteresis control switching unit G works and a hysteresis control logic unit H ceases an operation of two-bit divider unit D for a prescribed length of period with the hysteresis control operated. And with the knob of a high-scale position holding switching unit handled, a contact 56', 56" is closed to short-circuit a temperature setting volume 27 operating the high-scale operation for a prescribed length of period determined by a counter H.I. At this time, even if the hysteresis control is being operated, a switching can be made to the proportional temperature control during the time of a high-scale holding circuit being operated.
