    Abstract: At a time of starting of an operation, a controller determines whether the first operation was made after a power source being switched on in S1, and determines whether 5 minutes have passed after the previous operation in S2. When the first operation was not made or 5 minutes have lapsed after the last operation, the controller determines whether a difference between a detected temperature acquired by a thermistor and a preset temperature is more than 10° C. in S3. When a temperature difference is more than 10° C., a water flow rate servo is set at a position where a flow rate of flowing water is reduced from a determined flow rate by a predetermined amount in S4, and the controller performs a temperature control of discharged hot water in S8.
