きる。For safety reasons, the hot water supply to the bathtub 26 and the hot water supply to the shower 27 and shower 2 can be used at the same time if the hot water temperature is below 45°C, but if the temperature is higher than that, the hot water supply to the bathtub 26 is possible. I can only supply hot water. The fixed setting device 36 is of a porta-pull type so that it can be operated while in the bathtub 26 without moving the body, and can also be floated on the water surface of the bathtub 26. When the bathtub switch 54 is pressed, hot water is supplied, and when it is pressed again, it is stopped. It will also automatically stop when the water level reaches a predetermined level. The temperature can be changed using the temperature change switch 55, and the flow rate can be changed using the flow rate change switch 57.
これらスイッチ類の操作信号は、発信部５８から信号発

のスイッチを操作して止めることができるものである。The priority relationship between the operations of the fixed setting devices 36 and 38 and the main setting device 37 is such that the one operated later in time has priority. Therefore, when changing the temperature or flow rate, the value of the main setting device 37 can be changed by operating the fixed setting device 36.3 later. In addition, the bathtub switch 4 can be used to start and stop hot water supply.
0, the bathtub switch 54, the shower switch 42, and the shower switch 59 are connected in parallel in an electrical circuit, and hot water supply can be started and stopped by operating either switch, and hot water supply can be started by using one switch. It can be stopped by operating the other switch.

いる。As an effect of this embodiment, since the fixed setters 36 and 38 have the main setting function of the main setter 37, the fixed setters 36 and 38 have the main setting function of the main setter 37.
．． 38 also allows the main functions of hot water supply to be set, and the fixed setting devices 36 and 38 have the advantage of being easy to operate since there are no many switches. Fixed setting device 36.
Since a plurality of units 38 are provided, it has the effect that hot water supply instructions can be given from a plurality of hot water supply points. Furthermore, since signals are transmitted wirelessly between the fixed setting device 36.3B and the main setting device 37, there is no need for wiring work and the device can be installed at any location. Furthermore, since signals are transmitted between the main setting device 37 and the controller 25 using optical fiber, there is no risk of electrical leakage even if the main setting device 37 is installed in a humid or humid place around the bathroom. have.
