れる。On the other hand, temperature control device 5 processes the serial signal sent from each remote controller according to the flowchart shown in FIG. 2, and updates hot water control temperature memory 4. First,
The temperature control device 5 determines whether or not the serial signal is issued from the bathroom remote controller 13 based on the address signal included in the serial signal. As a result, when it is determined that it belongs to the remote controller 13 for the bathroom, the new hot water control temperature (30 ° C to 80 ° C) is stored in the hot water control temperature memory 4 according to the temperature setting signal included in the serial signal. Is written. If it is determined that the remote controller 14 or 15 is not for the bathroom, then it is determined whether the temperature setting signal is lower than 60 ° C. If the temperature is less than 60 ° C., a new hot water outlet control temperature is written in the hot water outlet control temperature memory 4 in accordance with the temperature setting signal. Also, 60 ℃
With the above, the tapping temperature is written as 60 ° C.
