In this case, when the hot water tap switch (71) is turned on to open a specific hot water tap (5) (for example, the hot water tap (5) shown at the highest level in FIG. 3), the output from the hot water tap FF (74) The hot water tap (5) is opened specifically to the above, and hot water can be taken out from the hot water tap (5). When the stop switch (72) belonging to the hot-water tap (5) that has performed the hot-water discharge operation is turned on, the water flow switches (67), () corresponding to the other hot-water taps (5), (5) (in the closed state). 67) is OFF,
The first AND circuit (76) (the AND circuit shown in the highest order) corresponding to the stop switch (72) that has been turned on outputs an "H" signal to throttle the throttle valve (4), and the throttle valve (4) When the signal is output from the closing detection switch (45) when the hot water is in the maximum throttle state, the signal is applied to the first OR circuit (78) that controls the hot water tap (5) that has stopped the hot water discharge, and the corresponding hot water is discharged. FF (74) is reset. As a result, the hot water tap (5) is closed and the hot water discharge operation is stopped.

Now, when the two hot water taps (5), (5) (for example, the upper two hot water taps in FIG. 3) are in the open state, for example, the hot water from the hot water tap (5) shown above is stopped. Therefore, even if the stop switch (72) belonging to this is turned on, the first AND circuit (76) shown in the upper portion does not output the "H" signal. Hot water tap (5) shown in the center of FIG.
The water flow switch (67) inserted in the branch flow path (37) to (in the open state) outputs an ON signal, and the ON signal corresponds to the stop switch (72) that has been operated to perform the first AND circuit. The "H" signal is prevented from being output from the first AND circuit (76) by being applied to (76).

Therefore, in this case, the throttle valve (4) is not throttled, and the other hot water tap (5) in the open state is used.
The hot water supply operation from (the hot water tap in the center of the figure) can be continued. The signal of the stop switch (72) that has been turned on is applied to one input terminal of the corresponding second AND circuit (77) (the second AND circuit (77) shown at the top in this example). To be done. The ON signal of the water flow switch (67) corresponding to the hot water tap (5) in the open state is applied to the input part of the third OR circuit (84) connected to the other side of the second AND circuit (77). Therefore, the third OR circuit (84) corresponding to the operated specific stop switch (72) outputs the "H" signal and the corresponding second AND circuit (77) outputs the "H" signal. Then, the first OR circuit (7
The hot water supply tap (5) is closed via the hot water supply FF (74) reset input terminal for controlling the opening and closing of the hot water supply tap (5) which is operated to stop hot water supply via 8).
