Power consumption control
DISABLED [4‑08]=0
▪ 0 (None)(default): Backup heater and
anti-legionella heater can operate
simultaneously.
▪ 1 (BSH): The anti-legionella heater is
prioritized.
▪ 2 (BUH): The backup heater is
prioritized.
Power consumption control
ENABLED [4‑08]=1 or 2
▪ 0 (None)(default): Depending on the
power limitation level, the anti-
legionella heater will be limited first,
before the backup heater is limited.
▪ 1 (BSH): Depending on the power
limitation level, the backup heater will
be limited first, before the anti-
legionella heater is limited.
▪ 2 (BUH): Depending on the power
limitation level, the anti-legionella
heater will be limited first, before the
backup heater is limited.
Note:
In case of power consumption control is DISABLED (for all
models) the setting [4‑01] defines whether backup heater and anti-
legionella heater can operate simultaneously, or if the anti-legionella
heater/backup heater has priority over the backup heater/anti-
legionella heater.
In case of power consumption control is ENABLED (only for
08), the setting [4‑01] defines the priority of the electrical
heaters depending on applicable limitation.
Average timer
The average timer corrects the influence of ambient temperature
variations. The weather-dependent set point calculation is done on
the average outdoor temperature.
The outdoor temperature is averaged over the selected time period.

▪ 4: 72 hours
Offset temperature external outdoor ambient sensor
Only applicable in case of an external outdoor ambient sensor is
installed and configured.
You can calibrate the external outdoor ambient temperature sensor.
It is possible to give an offset to the thermistor value. The setting can
be used to compensate for situations where the external outdoor
ambient sensor cannot be installed on the ideal installation location
(see installation).

Forced defrost
You can manually start a defrost operation.
The decision to execute the manual defrost operation is made by the
outdoor unit and depends on ambient and heat exchanger
conditions. When the outdoor unit accepted the forced defrost
operation, will be displayed on the user interface. If is NOT
displayed within 6 minutes after forced defrost operation was
enabled, the outdoor unit ignored the forced defrost request.

Pump operation
When the pump operation function is disabled the pump will stop if
the outdoor temperature is higher than the value set by [4‑02] or if
the outdoor temperature drops below the value set by [F‑01]. When
the pump operation is enabled, the pump operation is possible at all
outdoor temperatures.
