Thermostats and external sensors
# 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.
▪ 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.
