Abstract

PURPOSE:To economize electricity, by supplying electric power to the timing unit, which controls a switching element control means by a timely output signal, during a set time. CONSTITUTION:Normally, when the self-holding function and timing unit 6 are operated by the operation of switch 7 at the first, a signal is output only for a set time. This signal turns on transistor TR20. Simultaneously, variable resistance 15 is short-circuit. The unit is set to a maximum as the blind controller of the temperature independently of the value of resistance 15. Since unit 6 is connected to TR24, TR24 is turned on, and the base and the emitter of TR25 are short-circuit, and therefore, SCR3 becomes conductive by the control signal output from terminal 4' of control circuit 4 and rises up to a settable maximum temperature and holds this temperature.
