sterilization, the preset circular sterilization function still works.)
OFF reminder for sterilization failure:
If the OFF icon is displayed at the clock position after the STERILIZATION function is started,
sterilization fails and the water temperature required for sterilization cannot be reached. The OFF
reminder can be canceled when any button is pressed.
The OFF reminder only indicates that sterilization fails for this time without affecting circular
sterilization.
The OFF reminder is shown in the following figure.
Notes:
①
When time goes from 23:59 to 00:00, the system enters a new day, which is the basis for increasing
the number of days.
②
Every time after the STERILIZE function is started or sterilization parameters are adjusted in the
sterilize function setting interface, sterilization will be performed for once immediately and the day
interval for sterilization will be recalculated accumulatively. Even when sterilization is being
performed, operations such as sterilize function resetting and day interval adjusting for sterilization
will also cause recalculation of the day interval.
③
After the circular sterilization function is set, the water heater can still precisely calculate the day
interval for sterilization accumulatively and the circular sterilization function can still work in the case
of short-term power failure. If the time point for sterilization is within the power failure duration,
sterilization will be made up once power is provided again. In addition, the day interval for
sterilization will be recalculated accumulatively based on this sterilization and next sterilization will be
calculated accordingly.
④
Ensure that there is no long-term power failure; otherwise, the clock of the water heater will
malfunction and the STERILIZE function will not work properly.
⑤
Under the E-HEATER mode, the STERILIZE function is unavailable.
