Abstract:

PROBLEM TO BE SOLVED: To provide a hot water/water mixing device capable of draining water while distinguishing between a time of reset of power source and a time of recovery from power failure, and preventing tapping of high-temperature hot water in the recovery from power failure in a normal use.SOLUTION: A hot water/water mixing device 1 mixing a water of high temperature and water of low temperature to an auxiliary heat source machine 3, and tapping hot water of a set temperature, includes a draining mode for setting a plurality of valve means to draining positions by implementing reset of power source for temporarily stopping power supply and then restarting the same. A control unit 20 is communicatably connected to the auxiliary power source machine 3 to communicate with the auxiliary heat source machine 3 in detecting the reset of power source, to transfer to the draining mode in not detecting a communication signal, and to implement normal control without transferring to the draining mode in detecting the communication signal.SELECTED DRAWING: Figure 2
