Abstract
PURPOSE: To remove hysteresis effect in the proportional valve and improve the control characteristics thereof by a method wherein a bidirectional constant voltage circuit is inserted in series with an integral capacitor in a PID control circuit inputting a hot-water outlet temperature deviation signal in the proportional valve control circuit.
CONSTITUTION: A hot-water heater has the proportional valve 13 varying the opening degree thereof continuously in accordance with conducted current to control increase and decrease of the volume of supplied gas, and the proportional valve 13 is controlled by a control device in accordance with the output of a thermistor 18 detecting a hot-water temperature at the hot-water outlet of the hot-water heater. The control device comprises the PID control circuit inputting a differential output between the thermistor 18 and a temperature setting variable resistor VR and effecting an integrating operation principally and a constant current driving circuit supplying a current in accordance with the output of the PID control circuit. In this case, the PID control circuit connects a circuit in which the same kind of diodes 63, 64 are connected in anti-parallel connection to the integral capacitor 62 of the including integral circuit. According to this method, the hystresis effect in the proportional valve may be removed.
