ることを特徴とする燃焼制御回路。In a combustion control circuit using a microcomputer that confirms the presence of flame by a flame detection circuit and controls the opening and closing of the gas main valve, there is a watch dog timer and a watch dog timer that derive continuous output when the microcomputer is operating normally. , turned on by the output of the watch dog timer.
a power supply circuit that is turned off; a power supply lamp that indicates the application of the power supply circuit; a combustion lamp connected to an excitation circuit of a gas source valve; and a switching circuit that bypasses the power supply lamp circuit; The combustion control circuit is characterized in that the switching circuit that bypasses the power lamp circuit is turned on and off by a flashing signal based on an abnormality processing program from a microcomputer, thereby causing the power lamp to blink to indicate an abnormality.
