Sensors
External sensor
# Code
[9.B.1] [C–08] External sensor : When an optional
external ambient sensor is connected,
the type of the sensor must be set.
▪ 0 None : NOT installed. The thermistor
in the user interface and in the outdoor
unit are used for measurement.
▪ 1 Outdoor: Connected to PCB of the
indoor unit measuring the outdoor
temperature.
functionality, the temperature sensor
in the outdoor unit is still used.
▪ 2 Room: Connected to PCB of the
indoor unit measuring the indoor
temperature. The temperature sensor
in the user interface is NOT used
anymore. Remark: This value has
only meaning in room thermostat
control.
Ext. amb. sensor offset
ONLY applicable in case an external outdoor ambient sensor is
connected and configured.
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
[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 set point calculation is done on
the average outdoor temperature.
The outdoor temperature is averaged over the selected time period.

Brine low pressure switch
When a brine low pressure switch is installed, the unit must be
configured to work with the switch. When the switch is removed or
disconnected, this setting must be set to OFF.

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
[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.
▪ If Bivalent is enabled: When the outdoor temperature drops
below the bivalent ON temperature (fixed or variable based on
energy prices), the space heating by the indoor unit stops
automatically and the permission signal for the auxiliary boiler is
active.
▪ If Bivalent is disabled: Space heating is only done by the indoor
unit within the operation range. The permission signal for the
auxiliary boiler is always inactive.
The switch-over between the heat pump system and the auxiliary
boiler is based on the following settings:
▪ [C‑03] and [C‑04]
▪ Electricity prices ([7.5.1], [7.5.2] and [7.5.3])
[C‑03], [C‑04], and T

Based on the settings above, the heat pump system calculates a
value T , which is variable between [C‑03] and [C‑03]+[C‑04].
