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.
# Code
[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.
▪ 1 (Thermo ON/OFF): The connected
external room thermostat or heat
pump convector sends the heating
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
convector (FWXV).
▪ 2
connected external room thermostat
sends separate heating 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.
Remark: Only possible to use as a
heating application.
[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).
