SAVE
This mode is similar to the HOTWATER mode. However, this mode
allows only the heat pump but not the electrical heater for heating.
Note:
The SAVE mode requires proper temperature setpoint. It is re
-
commended that this mode is adopted when the required water tempe
-
rature is not higher than 50°C. If the temperature setpoint is too high or
the ambient temperature is too low and when the capacity of the heat
pump is insufficient, the error code L6 will be displayed and heating will
be stopped. In this case, decrease the temperature setpoint to a value
which is lower than the actual water temperature. Then, L6 will disappe
-
ar automatically.
PRESET
This mode enables time presetting for using the hot water. The unit
determines when to start based on the ambient temperature and the
difference between the preset water temperature and the actual water
temperature. When the preset period elapses, one hour later, the unit
will stop. Once setup, this mode runs circularly every day.
NIGHT
The unit will start or stop at the fixed period from 00:00-06:00 based on
the difference between the temperature setpoint and the actual water
temperature. Beyond this period, the unit keeps off. Once setup, this
mode runs circularly every day.

RAPID
The electrical heater is started to prepare hot water rapidly to meet
the urgent need for hot water.This function is available only when
the water tank equipped with the auxiliary electrical heater.
I-KNOW
The unit simulates the user’s habitual operation by collecting and
analyzing water data in some period and then realizes the automatic
operation. And it will remain medium water temperature when the user
does not require large amount of hot water.
