Contact type main
In external room thermostat control, the
contact type of the optional room
thermostat for the main leaving water
temperature zone must be set. See
"5 Application guidelines" on page 12
▪ 1 (Thermo ON/OFF) (default): The
connected external room thermostat
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 control box (X2M/1).
▪ 2 (H/C request): 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 control box (X2M/1 and 1a). Select
this value in case of connection with
the wired (EKRTWA) or wireless
(EKRTR1) room thermostat.
Option box EK2CB07CAV3
Modification of these settings is only required when option box
EK2CB07CAV3 is installed. Option box EK2CB07CAV3 has multiple
functionalities which need to be configured. See

Alarm output
Indicates the logic of the alarm output on
option box EK2CB07CAV3 during a
malfunction.
▪ 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. This installer setting allows for
a distinction between the detection of
an alarm, and the detection of a power
failure.
Also see the table below (Alarm output
logic).

sensor, connected to the outdoor unit.
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): Remote indoor
sensor, connected to option box
EK2CB07CAV3.
The
temperature
sensor in the user interface is NOT
used anymore.
Remark:
This value
has only meaning in room thermostat
control.
INFORMATION
You can only connect either the remote indoor sensor or
the remote outdoor sensor.
