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.

[1-0A]
Outdoor average timer:
▪ 0: No averaging (default)
▪ 1: 12 hours
▪ 2: 24 hours
▪ 3: 48 hours
▪ 4: 72 hours
INFORMATION
If the power saving function is activated (see [E‑08]), the
average outdoor temperature calculation is only possible in
case the external outdoor temperature sensor is used. See
"5.6 Setting up an external temperature sensor" on
page 15
.
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.
