<p>PURPOSE:To enable a resetting to be carried out from a hot water supplying location and at the same time to enable a cause of stopping of combustion to be conformed while a hot water supplying plug being closed by a method wherein in the event that an abnormal state is detected to terminate the combustion, a water supplying stop signal is once outputted from a water amount switch, thereafter a water supplying sensing signal for restarting the supplying of water is outputted and thereafter a safety device is reset. CONSTITUTION:When abnormal states such as a diminishing of fire or an over-heating in a device or the like occur, an error discriminating part 3 discriminates an occurrence of abnormal state in reference to a sensing signal of each of sensor groups 5 to output an error signal. When a data signal indicating an abnormal state is outputted at an error data making part 4, an operation stop signal is outputted from a control signal output part 23 through an error processing part 22 and all loads 6 are stopped. As a hot water supplying plug is closed, it is judged by a sensing signal of a water amount sensor 51 whether or not the hot water supplying plug is released. As the hot water supplying plug is released, a control part 1 of a main body, sensor groups 5 and a remote operating part 7 or the like are reset and then an operation is returned to its normal initial state. For this state, it is possible to restart the hot water supplying operation.</p> |
