[A.2.2.3] [E-07] During domestic hot water preparation,
the heat pump can be assisted by an
electrical heater to ensure the domestic
hot water preparation even for high
desired tank temperatures.
DHW tank heater:
Q
0 (Horizontal BSH): Installed at side
of the tank. Default for EHBH/X.

EHVH/X. The backup heater will
also be used in domestic hot water
heating.
[A.2.2.A] [D-02] The indoor unit offers the possibility to
connect a field supplied domestic hot

# Code Description
[A.2.2.4] [C-05] Contact type main
In external room thermostat control, the
contact type of the optional room
thermostat or heat pump convector for
the main leaving water temperature zone
must be set. See "5 Application
guidelines" on page 6.
Q
1 (Thermo ON/OFF): The
connected external room thermostat
or heat pump convector sends the
heating or cooling demand by the
same signal as it is connected to
only 1 digital input (preserved for the
main leaving water temperature
zone) on the indoor unit (X2M/1).
Select this value in case of a
connection to the heat pump
convector (FWVX).
Q
2 (C/H request)(default): The
connected external room thermostat
sends separate heating and cooling
demand and is therefore connected
to the 2 digital input (preserved for
the main leaving water temperature
zone) on the indoor unit (X2M/1 and
2). Select this value in case of
connection with the wired
(EKRTWA) or wireless (EKRTR1)
room thermostat.
[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. See "5 Application
guidelines" on page 6.
Q
1 (Thermo ON/OFF): See Contact
type main. Connected on the indoor
unit (X2M/1a).
Q
2 (C/H 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. See "5 Application
guidelines" on page 6.
Q
0 (No)(default): NOT installed. The
thermistor in the user interface and
in the outdoor unit are used for
measurement.
Q
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.
Q
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.
