Abstract

PURPOSE: To secure a continuous control for the heat output by controlling the output in multiple steps and with variation of the pulse intervals.
CONSTITUTION: Temperature detecting output ports 6W9 provided to microcomputer 1 are connected to input 15 of comparator 14 via resistances 10W13 one end of which is used in common to each other as well as to power source 17 via resistance 16. The other input 18 of comparator 14 is grounded via thermistor 19 as well as connected to power source 17. The output of comparator 14 is grounded via resistance 21 and also connected to input port 22. Output port 23 is grounded via resistance 24 and photo diode 25 of the photo coupler. Then the output of comparator 14 is converted into the long and short pulse intervals via microcomputer 1 and then delivered to port 23 to give the control so that the heat output may be within the range of set temperatures.
