Abstract (en)
A control circuit 31 for use with valve means 30 for controlling the supply of fuel to a fuel using appliance e.g. a domestic or gas oven incorporates a switching circuit operative to send a signal to open said valve means 30, or prevent the sending of such signal, and a checking circuit, the checking circuit ensuring that prior to such a signal being sent, the switching circuit is initially in a condition such that the signal can not be sent so as to ensure that prior to fuel being supplied to the burner of the fuel using appliance, the circuit is in a fail-safe condition. Such a control circuit is of particular benefit for use with flueless gas using appliances.
