Abstract

PURPOSE:To prevent the generation of operational failures, such as a drop in the water level of a water supply tank or temperature control trouble of a hot water/water mixing faucet by connecting a water outlet of said water supply tank with a water inlet of a hot water supply heater by way of a water pipeline for hot water supply equipped with a waver supply pump for the hot water supply heater on the way. CONSTITUTION:When the output of a water level sensor 14b drops below a pump suspension level during the supply operation of mixed hot water, a water supply pump 32 for a hot water supply heater 43 is adapted to come to a halt so that the pump 43 may prevent the suction of air. In the mean time, a water supply pump 32 for the hot water heater is in operation. When the water level of a hot water supply tank 14 is restored to a switch over level, hot water supply change over operation starts and a switch over signal is transmitted to a shower device side. Moreover, when water supply to a water supply tank 13 fails during the above control operations due to unexpected water failure, closure and failure of a ball tap, the water level of the water supply tank 13 drops and a lower limit float switch 13a is turned OFF, thereby halting the operation of water supply, hot water supply, and the water supply pumps 21, 43, and 32 for the hot water supply heater, and outputting a water failure signal and a hot water supply failure signal to the shower device side, canceling the above signals and the halting the operation of water supply and hot water supply.
