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.

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
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.

Pump operation during flow abnormality [F‑09] defines whether the
pump stops at flow abnormality or allow to continue operation when
flow abnormality occurs. This functionality is only valid in specific
conditions where it is preferable to keep the pump active when

INFORMATION
If glycol is present in the system ([E‑0D] set to "1") and a
flow abnormality occurs, then [F‑09] will have NO effect,
and the pump will continue operation (intervals of 20
minutes ON – 4 minutes OFF).
Pump speed limitation
Pump speed limitation [9‑0D] defines the maximum pump speed. In
normal conditions, the default setting should NOT be modified. The
pump speed limitation will be overruled when the flow rate is in the
range of the minimum flow (error 7H).
