# Code Description
[A.2.2.5] [C-06] Contact type add.
In external room thermostat control with
2 leaving water temperature zones, the
type of the optional room thermostat for
the additional leaving water temperature
zone must be set.
▪ 1 (Thermo ON/OFF): See Contact
type main. Connected on the indoor
unit (X2M/1a).
▪ 2 (H/C request)(default): See Contact
type main. Connected on the indoor
unit (X2M/1a and 2a).
[A.2.2.B] [C-08] External sensor
When an optional external ambient
sensor is connected, the type of the
sensor must be set.
▪ 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): Installed. The
temperature sensor in the user
interface is NOT used anymore.
Remark: This value has only meaning
in room thermostat control.
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.
# Code Description
[A.2.2.6.2] [D-07] Solar kit
Indicates if the domestic hot water tank
is also heated by thermal solar panels.
▪ 0 (No)(default): NOT installed.
▪ 1 (Yes): Installed. The domestic hot
water tank can –besides by the boiler–
also be heated by thermal solar
panels. Set this value if thermal solar
panels are installed.
[A.2.2.6.3] [C-09] 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.
Alarm output logic
[C-09] Alarm No alarm No power
supply to unit
0 (default) Closed output Open output Open output
1 Open output Closed output
Demand PCB
The demand PCB is used to enable the power consumption control
by digital inputs.
# Code Description
[A.2.2.7] [D-04] Demand PCB
Indicates if the optional demand PCB is
installed.
▪ 0 (No)(default)
▪ 1 (Pwr consmp ctrl)
Energy metering
When energy metering is performed by the use of an external power
or gas meter (field supply), configure the settings as described
below. Select the pulse frequency output of each meter in
accordance with the meter specifications. It is possible to connect a
power meter and a gas meter with different pulse frequencies. When
no power meter or gas meter is used, select No to indicate the
corresponding pulse input is NOT used.
# Code Description
[A.2.2.8] [D‑08] Optional external kWh meter1:
▪ 0 (No)(default): NOT installed
▪ 1: Installed (0.1pulse/kWh)
▪ 2: Installed (1pulse/kWh)
▪ 3: Installed (10pulse/kWh)
▪ 4: Installed (100pulse/kWh)
▪ 5: Installed (1000pulse/kWh)
[A.2.2.C] [D‑0A] Optional gas meter:
▪ 0 (No)(default): NOT installed
▪ 1: Installed (1pulse/m³)
▪ 2: Installed (10pulse/m³)
▪ 3: Installed (100pulse/m³)
Savings mode
The user can choose whether switching between operation modes is
either economically or ecologically optimised. Set to Economical, the
system will in all operating conditions select the energy source (gas
or electricity) based on energy prices, resulting in a minimisation of
energy costs. Set to Ecological, the heat source will be selected
based on ecological parameters, resulting in a minimisation of
primary energy consumption.
# Code Description
[A.6.7] [7‑04] Defines whether switching between
operation modes is either economically
or ecologically optimised.
▪ 0 (Economical)(default): reduction of
energy costs
▪ 1 (Ecological): reduction of primary
energy consumption, but not
necessarily energy costs
Primary energy factor
The primary energy factor indicates how many units of primary
energy (natural gas, crude oil, or other fossil fuels, prior to
undergoing any human-made conversions or transformations) are
needed to obtain 1 unit of a certain (secondary) energy source, such
