Abstract
PURPOSE: To prevent the pump from locking phenomna, by actuating a heating water circulating pump for a prescribed period even when hot water is supplied.
CONSTITUTION: A delay circuit comprising a timer circuit 28, a relay 29 and a relay contact 27 is provided in a driving control circuit of the room heating water circulating pump. When a hot water supply flow switch 21 is closed, and an electric current is passed through the relay 22, a driving circuit 23 of a burner 7 for supplying hot water, a pilot flame detecting circuit 24 for supplying hot water, and a temperature controlling circuit 25 are actuated, and at the same time the relay contacts 26, 27 are closed to actuate the room heating hot water circulating pump 3 and the timer circuit 28. After a prescribed period, as the timer circuit 28 passes an electric current to the relay 29, the relay contact 30 is opened to suspend the operation of the hot water circulating pump 3. Accordingly, the locking phenomena of the pump can be prevented.
