By the way, 1 can 2 with proportional control of hot water supply like this
In a circuit water heater with reheating, when reheating is performed, the temperature detected by the temperature detector 12 also rises due to reheating, so for example, if the set temperature of the temperature setting device 23 is low, the bath will be at an appropriate temperature. Even if the set temperature of the setter 23 is high enough, the reheating time is long, so when reheating, the temperature setter 23 must be reset to a high temperature. It will not happen.
