You can calibrate the external outdoor ambient temperature sensor. It is possible
to give an offset to the thermistor value. This setting can be used to compensate
for situations where the external outdoor ambient sensor cannot be installed on
the ideal installation location.
# Code Description
[9.B.2] [2-0B] Ext. amb. sensor offset: Offset on the
ambient temperature measured on the external
outdoor temperature sensor.
▪ –5°C~5°C, step 0.5°C
Averaging time
The average timer corrects the influence of ambient temperature variations. The
weather-dependent setpoint calculation is done on the average outdoor
temperature.
The outdoor temperature is averaged over the selected time period.
# Code Description
[9.B.3] [1-0A] Averaging time:
▪ 0: No averaging
▪ 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 "6.6Setting up an external temperature sensor"[451].
Bivalent
Bivalent
Only applicable in case of auxiliary boiler.
About bivalent
The purpose of this function is to determine which heating source can/will provide
the space heating, either the heat pump system or the auxiliary boiler.
# Code Description
[9.C.1] [C-02] Bivalent: Indicates if the space heating is also
performed by means of another heat source than
the system.
▪ 0 No: Not installed
▪ 1 Yes: Installed. The auxiliary boiler (gas boiler,
oil burner) will operate when the outdoor
ambient temperature is low. During bivalent
operation, the heat pump is turned off. Set this
value in case an auxiliary boiler is used.
