Abstract

PURPOSE:To achieve small sized and low cost device, by concentratingly controlling a plurality of heating appliances with a common control section is time division. CONSTITUTION:A detection output of thermisters 111-11n and a set value of temperature setters 161-16n are respectively given to multiplexers 13 and 17. The detected output and the set output are synchronized and given to a differential amplifier 15, and an output difference is generated from the amplifier 15 only when the detected output is smaller than the set output, and the result is stored in a memory 19. The stored data in the memory 19 is given to a comparator 21 and sequentially compared with an output time-dividing a specified time of a counter 22. If the 10th and 12nd data are coincident with the 2nd output of the counter 22, an output takes place from a comparator 21 from the coincident point. This output resets FFs 2410 and 2412. Thus, the FF2410 and 2412 turn on only when the 2nd output is given to energize heaters 2710 and 2712.
