6.6.4 STERILIZE
The STERILIZE function is available under four common modes. However, after this function is
set, the unit runs as under the HOTWATER mode. The water heater controls startup and shut

down of the unit based on the difference between the actual water temperature and that required
for sterilization.
In the On state and in a common mode, press the FUNCTION button to enter the function selec
-
tion interface. When the STERILIZE function is selected, the corresponding icon blinks. At the
same time, the preset circular sterilization duration is displayed as d:XX, as shown in the following
figure.
During this period, the following operations can be performed:
1. Press

to start or cancel the STERILIZE function. If this function is started, the STERILIZE
icon is displayed without blinking. Sterilization will be performed circularly by the preset d and h
value; If this function is canceled, the STERILIZE icon is not displayed. If no operation is performed
within 5 seconds, it will be regarded that this function is not required. After this function is started
