時マイコンリセツト回路。[Scope of Claim for Utility Model Registration] (1) A relay 27 for driving a solenoid valve of a gas heater is connected to output port 1-C of the microcomputer 1;
A compressor drive relay 29 of the refrigerator is connected to D, and an output port for pulse generation is connected between another output port 1-B of the microcomputer 1 that generates pulses with a constant duty and the reset input port 1-A of the microcomputer 1. When the output of 1-B generates a pulse with a constant duty, no reset is applied and the output is H or L.
A microcomputer reset circuit when a microcomputer runs out of control is connected to a forced reset means 25 which resets the microcomputer when the microcomputer is fixed. (2) The microcomputer reset circuit in the event of microcomputer runaway according to claim 1 of the utility model registration, characterized in that the output port 1-B generates a pulse with a constant on-time.
