A Main leaving water temperature zone
B One single room
a Remote controller of the heatpump convectors
▪ The heat pump convectors are directly connected to the indoor
unit.
▪ The desired room temperature is set via the remote controller of
the heat pump convectors.
▪ The space heating/cooling demand signal is sent to one digital
input on the indoor unit (X2M/35 and X2M/30).
▪ The space operation mode is sent to the heatpump convectors by
one digital output on the indoor unit (X2M/4 and X2M/3).
INFORMATION
When using multiple heat pump convectors, make sure
each one receives the infrared signal from the remote
controller of the heatpump convectors.
Configuration
Setting Value
Unit temperature control:
▪ #: [2.9]
▪ Code: [C-07]
1 (External room
thermostat): Unit operation is
decided by the external
thermostat.
Number of water temperature
zones:
▪ #: [4.4]
▪ Code: [7-02]
0 (Single zone): Main
External room thermostat for the
main zone:
▪ #: [2.A]
▪ Code: [C-05]
1 (1 contact): When the used
external room thermostat or
heatpump convector can only
send a thermo ON/OFF
condition. No separation between
heating or cooling demand.
Benefits
▪ Cooling. The heat pump convector offers, besides heating
capacity, also excellent cooling capacity.
▪ Efficiency. Optimal energy efficiency because of the interlink
function.
▪ Stylish.
Combination: Underfloor heating + Heatpump
convectors
▪ Space heating is provided by:
▪ The underfloor heating
▪ The heatpump convectors
▪ Space cooling is provided by the heatpump convectors only. The
underfloor heating is shut off by the shut-off valve.

B One single room
a Remote controller of the heatpump convectors
▪ The heat pump convectors are directly connected to the indoor
unit.
▪ A shut-off valve (field supply) is installed before the underfloor
heating to prevent condensation on the floor during cooling
operation.
▪ The desired room temperature is set via the remote controller of
the heat pump convectors.
▪ The space heating/cooling demand signal is sent to one digital
input on the indoor unit (X2M/35 and X2M/30).
▪ The space operation mode is sent by one digital output (X2M/4
and X2M/3) on the indoor unit to:
▪ The heatpump convectors
▪ The shut-off valve

Benefits
▪ Cooling. Heat pump convectors provide, besides heating
capacity, also excellent cooling capacity.
▪ Efficiency. Underfloor heating has the best performance with the
heat pump system.
▪ Comfort. The combination of the two heat emitter types provides:
▪ The excellent heating comfort of the underfloor heating
▪ The excellent cooling comfort of the heatpump convectors
5.2.2 Multiple rooms – OneLWT zone
If only one leaving water temperature zone is needed because the
design leaving water temperature of all heat emitters is the same,
you do NOT need a mixing valve station (cost effective).
Example: If the heat pump system is used to heat up one floor
where all the rooms have the same heat emitters.
