Abstract

PURPOSE: To retain the output of a comparator at its fuel stop side in a temperature control circuit for a combustion equipment to thereby protect a transistor in the control circuit against damage by raising standard voltage and fixing a detecting voltage to a lower voltage than the standard voltage when a thermistor is disconnected.
CONSTITUTION: A standard voltage branched from a mid-point of resistors R5 and R6 connected in series with a DC power supply line is applied to the inverting input side of a comparator 1, and the other side of the resistor R6 is connected in series with a transistor TR1. Detected voltage VTH branched from a mid-point of a resistor R2 connected in series with a power supply line, a temperature setting variable resistor VR and a hot water temperature detecting thermistor TH is applied to the non-inverting input of the comparator 1. A resistor R3 is connected in series with the input line of the detected voltage, and a capacitor C3 is inserted between the input line and the power supply line (-)l to thus form an integrating circuit. A resistor R4 is connected across the capacitor C3 to thereby limit the upper limit of the detecting voltage.
