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 8.
▪ 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
(C/H
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.
