Abstract

PURPOSE:To improve both the temperature control property and the transient temperature property, by varying the proportion output signal with the integral output signal not by piling the integral output over the proportion output signal. CONSTITUTION:The capacitor 23 which delivers the integral value is connected to one side of the proportion control bridge circuit by the transistor 27 and the fixed resistance 28 which form an emitter-follower circuit. Thus with increment of the both-terminal voltage of the capacitor 23, the set temperature of the proportion control circuit is increased automatically to compensate the deviation of temperature which is caused when a control is given only by the proportion output signal. The thermistor 7 has a large value of resistance when the temperature supplied is low and energizes the transistors 16 and 17. Thus the coil 10 is driven to supply the gas to a gas burner and thus increase the temperature of the hot water to be supplied.
