METHOD FOR SUPPLYING FILLING WATER OF GAS BOILER

摘要

PURPOSE: A method for supplying filling water of a gas boiler is provided to stop an operation to supply filling water and to inform a suspension of water supply to a user when filling water is not supplied by the suspension of water supply. CONSTITUTION: When a low water level of a water tank is detected, a count of a counter to count an operating number of operations for supplying filling water is increased and a circulating pump is turned off. Filling water is supplied to the water tank by driving a valve of filling water. When a supply of filling water is not checked through an electrode, the operation for supplying the filling water is repeated until three times. When the supply of filling water is not checked after three times, the operation is stopped and a suspension of water supply is informed to a user. Thereby an unnecessary power consumption generated by repeatedly turning on/off the valve of filling water is prevented and a damage of the filling water valve is prevented.
