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 to the
heat pump convector (FWXV).
▪ 2 (H/C request)(default): The 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.
