Consists of work. By performing the above work in advance, thereafter, by determining the desired bathtub water level with the UP switch 76a and the DOWN switch 76b for setting the bathtub water level of the bath remote controller 70, the corresponding physical value is the judgment reference value. When the water level sensor 29 detects the determination reference value when hot water is supplied to the bathtub, the hot water supply is stopped and a predetermined water level can be obtained.

However, when a trader or the like inputs the bathtub water level setting data by mistake, it is necessary to cancel the data and input correct data again.
In this case, the bathtub water level setting data of the microcomputer 61 of the main remote controller 60 can be quickly reset without waiting for the voltage drop of the backup power source, so that the data re-input operation can be performed quickly. The method will be described with reference to FIG.

The microcomputer 90 of the bath remote controller 70 determines whether or not both the UP switch 76a and the DOWN switch 76b for setting the bath water level are simultaneously turned on by a trader (S1, S2) and turned on at the same time. If you are in a state,
Further, it is judged whether or not the state continues for a certain period of time or more, for example, for a certain period of time within 0.5 to 5 seconds (S3). Output to the microcomputer 61 of the main remote controller 60 (S4). Then, the output confirmation sound is uttered (S5). On the other hand, the microcomputer 61 of the main remote controller 60
Always determines whether or not a reset signal for bathtub water level setting data is received from the bath remote controller 70 side (S11), and if received, clears all bathtub water level setting data stored in the storage unit ( S12). Of course, the bathtub water level setting data may be stored in the bath remote controller 70. In this case, the bath remote control 70 clears the bathtub water level setting data.

In the above description, the bathtub water level setting data resetting operation is performed by using the bathtub water level setting UP-DOWN switch 76. Awareness of resetting is made. In addition, it is necessary to press both the UP switch 76a and the DOWN switch 76b for setting the bath water level at the same time, which ensures safety so as not to be reset by a child's mischief or a simple mistake in pressing.
