type of the optional room thermostat or heat
pump convector for the main leaving water
temperature zone must be set. See
"5 Application guidelines" [
▪ 1 (Thermo ON/OFF): The connected external

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).
