3) Constant temperature control
To minimize the energy consumed by the heater and reduce the time required for washing, the cold water v/v and the hot
water v/v are properly controlled until the required water temperature is reached.
1. After operating the hot water v/v until it reaches the water level where it is possible to detect the water temperature, if it
fails to reach the target temperature, the hot water v/v will continue to operate. If the target temperature is met, then the
cold water v/v is operated.
2. Depending on whether the target temperature is reached, the cold and hot water v/v keeps turning on and off. In other
words, to prevent the water temperature from continuing to rise after reaching the target temperature, the hot water v/v
is turned off and the cold water v/v is turned on. As the cold water is supplied, the water temperature drops and when it
is 5 degrees below the target water temperature, then the hot water v/v is turned on and the cold water v/v is turned off
to raise the water temperature.
3. For the water supply cycle shown in 1 and 2, if the water level is met, then the water supply stops and it moves onto the
next washing cycle.
4. In the earlier stage, the hot water valve is used to supply water. If the hot water valve is closed or not connected then
there would be no difference in water level for 60 seconds. In this case, the constant water temperature control is
ignored and only cold water is supplied.
