Remote controller of the heat pump convectors
▪ The under floor heating or radiators are directly connected to the
outdoor unit – or to the backup heater, if there is one.
▪ 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 control box EKCB07CAV3 (X2M/1 and X2M/2).
The space operation mode is sent to the heat pump convectors by
one digital output on control box EKCB07CAV3 (X8M/6 and X8M/7).
INFORMATION
When using multiple heat pump convectors, make sure
each one receives the infrared signal from the remote
controller of the heat pump convectors.

Unit temperature control:
▪ #: [A.2.1.7]
▪ Code: [C-07]
1 (Ext RT control): Unit operation
is decided by the external
thermostat.
Number of water temperature
zones:
▪ #: [A.2.1.8]
▪ Code: [7-02]
0 (1 LWT zone): Main
External room thermostat for the
main
zone:
▪ #: [A.2.2.E.5]
▪ Code: [C-05]
1 (Thermo ON/OFF): When the
used external room thermostat or
heat pump convector can only
send a thermo ON/OFF
condition.
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: Under floor h Heat pump
convectors
▪ Space heating is provided by:
▪ The under floor heating
▪ The heat pump convectors
▪ Space cooling is provided by the heat pump convectors only. The
under floor heating is shut off by the shut-off valve.

Remote controller of the heat pump convectors
▪ The heat pump convectors are directly connected to the outdoor
unit – or to the backup heater, if there is one.
▪ A shut-off valve (field supply) is installed before the under floor
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 control box EKCB07CAV3 (X2M/1 and X2M/2)
▪ The space operation mode is sent by one digital output (X8M/6
and X8M/7) on control box EKCB07CAV3 to:
▪ The heat pump convectors
▪ The shut-off valve
