Abstract

PURPOSE: To make sure the control of low temeratures by use of a temperature- controlling unit wherein ignition operation is carried out by an output from comparison of a temperature signal and a set-up value, a main electromagnetic valve being operated by means of an ON-delay timer.
CONSTITUTION: Comparators 14, 16 are connected to a power source 12. The comparator 14 compares a signal from a temperature-sensitive element 4 and a temperature set-up value due to a variable resistance 15. If the temperature signal is lower than the set-up value, an output is delivered from the comparator 14 to actuate an OFF-delay timer 17. The output actuates an igniter 5. The comparator 16 delivers an output, based on a combustion-detection signal from a thermocouple 9, to AND circuit 18. The output from the comparator 14 and an AND signal are sent to an OR circuit 20 and an ON-delay timer 19, the signal from the timer 17 also being sent to the OR circuit 20. A pilot burner valve 10 opens on a basis of the OR signal. The delay time of the timer 19 may be controlled, and a main electromagnetic valve 7 opens after a predetermined time
