INFORMATION
The correct domestic hot water default settings becomes
only applicable when domestic hot water operation is
activated ([E‑05]=1).
Thermostats and external sensors
NOTICE
If an external room thermostat is used, the external room
thermostat will control the room frost protection. However,
the room frost protection is only possible if the leaving
water temperature control on the unit's user interface is
turned ON.
See "5 Application guidelines" on page 11 .
# 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 11 .
▪ 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 (FWXV).
▪ 2 (H/C 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 11 .
▪ 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).
# Code Description
[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 11 .
▪ 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. See
"5 Application
guidelines" on page 11 .
# Code Description
[A.2.2.6.1] [C-02] 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. See
"5 Application guidelines" on page 11 .
[A.2.2.6.2] [D-07] Solar kit
Only applicable for EHBH/X. 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 heat
pump– also be heated by thermal
solar panels. Set this value if thermal
solar
panels are installed. See
"5 Application guidelines" on page 11 .
