Setpoints for
operating modes
There are three operating modes for domestic hot water heating:
Normal
,
Boost
,
and Reduced .
The Home/Away function allows you to select between the Normal mode and the
Reduced
mode. With the Schedule function, you can schedule the system to switch
between the
Normal
and the
Reduced
mode on different weekdays and at different
times.
● When the domestic hot water boost function is activated from the Home view,
the operating mode will switch to Boost (and the tank will be heated up to the
boost temperature).
● The
Boost
function can be used only if using the in-line heater for domestic hot
water heating has been enabled (i.e. the additional heater’s Mode for heating
setting is either After compressor or With compressor ).

SETTINGS → LEGIONELLA INHIBITION
This function heats up the domestic hot water to a high temperature to prevent bacterial growth.
Temperature is kept at a high level for a specific period of time (the clean-up period). To achieve sufficient
temperature levels, the domestic hot water in the tank can be heated up using both the compressor and
the unit’s electric immersion heater.
● If domestic hot water temperature remains mostly at or above +55 °C, this function is usually not
necessary.
● The boost function can be used only if using the electric immersion heater for heating domestic hot
water has been enabled (i.e. the additional heater’s Mode for heating setting is either Legionella
inhibition, After compressor
or
With compressor)
.
Off
Legionella inhibition is disabled.
Legionella inhibition
Used
Legionella inhibition is enabled.
Time between starts
The interval between heating periods. This interval depends on the domestic hot
water temperature setting.
● If domestic hot water is usually kept only at a lukewarm temperature, use a
shorter interval.
● Usually, the interval should be set to 3–7 days.
Inhibit start time
The time of day at which the function is activated. Select a time when domestic hot
water is not typically used, such as nighttime hours.
Time to next start The number of days (d) before the function is activated again.
