フエールセーフ回路。[Claims for Utility Model Registration] A gas valve control circuit consisting of a first relay for opening and closing a gas valve for a water heater and a relay drive circuit for driving the first relay, and a power source for the first relay. A water heater control device comprising circuit means for deriving an operating state signal of the first relay, and outputting a first signal for operation to the relay drive circuit, and outputting an operating state signal from the circuit means. an abnormality determining means for determining an abnormality in the gas valve control circuit upon receiving the feedback and outputting a second signal when the abnormality occurs; and a second signal from the abnormality determining means.
a second relay that cuts off power supply to the first relay in response to a signal from the water heater controller.
