The temperature is displayed on the display panel 133. If no input is added for more than a certain time, the user sets the current temperature as the new setting temperature.

When the user lifts the lever 7 to the mixed water dedicated position and lifts it, the controller 160 compares the current temperature sensed by the temperature sensor unit 120 with the set temperature set by the user. When the difference between the two temperatures is more than ± 1 ° C., the controller 160 blinks the LED 134 and at the same time generates a control signal periodically as described above. The stepping motor 141 adjusts the amount of cold water supplied through the ceramic valve 142 while rotating one step in the clockwise or counterclockwise direction by the control signal so that the mixed water temperature approaches the set temperature.

In addition, the controller 160 continuously compares the current temperature and the set temperature, and when the two temperatures are maintained within ± 1 ° C., turns off the LED 134 and stops the control of the cold water supply controller 140 to stop the ceramic valve ( Keep 142 current. After that, when the supply amount or the water temperature of the hot or cold water is changed so that the mixed water temperature is changed rapidly, the controller 160 readjusts the water temperature to be close to the set temperature through the above process.

<For emergency situation>

The ceramic valve 142 of the cold water supply control unit 140 always maintains a somewhat open state at the end of use, but if the ceramic valve 142 is completely locked or opened slightly, an emergency such as a power failure may occur. It may occur. At this time, the user may be forced to open the ceramic valve 142 by operating the emergency opening rod 227 is located at the bottom of the main body 200 fixed to the shaft 142a.
