External sensor
When an optional external ambient
sensor is connected, the type of the
sensor must be set. See
.
▪ 0 (No)(default): NOT installed. The
thermistor in the user interface and in
the outdoor unit are used for
measurement.
▪ 1 (Outdoor sensor): Installed. The
outdoor sensor will be used to
measure
the
outdoor
ambient
temperature.
Remark:
For some
functionality, the temperature sensor
in the outdoor unit is still used.
▪ 2 (Room sensor): NOT applicable.
Digital I/O PCB
Modification of these settings is only needed when the optional
digital I/O PCB is installed. The digital I/O PCB has multiple
functionality which need to be configured. See

Ext. backup heat src
Indicates if the space heating is also
performed by means of another heat
source than the system.
▪ 0 (No)(default): NOT installed.
▪ 1 (Bivalent): Installed. The auxiliary
boiler (gasboiler, oil burner) will
operate when the outdoor ambient
temperature is low. During the bivalent
operation, the heat pump is turned
OFF. Set this value in case an
auxililary
boiler
is
used.

Alarm output
Indicates the logic of the alarm output on
the digital I/O PCB during
malfunctioning.
▪ 0 (Normally open)(default): The alarm
output will be powered when an alarm
occurs. By setting this value, a
distinction
is
made
between
malfunctioning and detection of a
power failure of the unit.
▪ 1 (Normally closed): The alarm output
will NOT be powered when an alarm
occurs.

Bottom plate heater
Only applicable for RHBH/X11+16 and
RHVH/X11+16. Indicates if an optional
bottom plate heater is installed on the
outdoor unit. The power of the bottom
plate heater is in this case supplied by
the indoor unit.
▪ 0 (No)(default): NOT installed.
▪ 1 (Yes): Installed.
Remark:
If this
value is set, the output on the digital I/
O PCB cannot be used for space

Energy metering
When energy metering is performed by the use of external power
meters, configure the settings as described below. Select the pulse
frequency output of each power meter in accordance with the power
meter specifications. It is possible to connect (up to 2) power meters
with different pulse frequencies. When only 1 or no power meter is
used, select No to indicate the corresponding pulse input is NOT
used.

Quick wizard: Capacities (energy
metering)
The capacities of all electrical heaters must be set for the energy
metering and/or power consumption control feature to work properly.
When measuring the resistance value of each heater, you can set
the exact heater capacity and this will lead to more accurate energy
data.
