PROBLEM TO BE SOLVED: To provide a water temperature control unit capable of controlling the sensory temperature comfortable for a user.SOLUTION: A water temperature control unit includes: a hot water mixing valve that discharges hot water while controlling the temperature to a predetermined degree; and a control section that controls the operation of the hot water mixing valve. A water temperature detection section detects the temperature of water flowing into the hot water mixing valve. The control section controls the hot water mixing valve so that the temperature of the discharged hot water changes between a predetermined upper limit temperature and a lower limit temperature which is determined based on a preset temperature in which an average value of the temperature of the discharged hot water is lower than a preset temperature. Even in a case that the set temperatures are identical to each other, when the water temperature detected by the water temperature detection section is the predetermined temperature or higher, the average temperature is set to be lower than the water temperature lower than the predetermined temperature. |
