CONTROL METHOD FOR THERMAL VALVE

摘要

The invention provides a method for controlling a thermal valve which eliminates need for substantial rush current as in the past and can be inexpensively configured and more reliably operated. The method for controlling the thermal valve 10 opened by application of a designated operating voltage Vr, wherein a voltage Va that is lower than the operating voltage Vr is initially applied for a designated time t as the applied voltage, thereby lowering the rush current. The applied voltage is then increased to the operating voltage Vr to open the thermal valve 10. Then, after a designated time T has passed, a voltage Vb that is lower than the operating voltage Vr is continuously applied to the thermal valve 10 to conserve consumption power.
