Further, after pulling out the upper portions of the respective control connection wirings 26 to 31 derived from the respective electromagnetic valves 17 to 21 and the hot water supply temperature sensor 25 that detects the hot water temperature in the hot water supply pipe 12 to the lower side of the partition plate 6, The upper unit 2 is attached to the upper half of the back plate 1.
is assembled.

As shown in FIG. 2, the lower unit 3 includes a lower cover 32 made of, for example, injection molded synthetic resin and having an open rear surface, and is assembled inside this, and each solenoid valve 17 to 21 of the shower piping unit 7 is connected to the lower cover 32. A control circuit main body 33 is provided.

Further, the lower cover 32 has its upper part connected to the upper cover 5.
At the same time, the rear part of the lower surface is connected to the back plate 1.
It is fixed to the back plate 1 and the upper unit 2 by screwing the lower edge of the unit with screws.

An operation panel 38 is provided on the front side of the lower half of the lower cover 32, and a controller chamber 39 in which the control circuit main body 33 is housed is formed on the back side thereof. The controller chamber 39 is extended rearward from the front surface of the lower cover 32.
