5 Application guidelines
Setting
Number of water temperature
zones:
▪ #: [4.4]
▪ Code: [7-02]
External room thermostat for the
main zone:
▪ #: [2.A]
▪ Code: [C-05]
Benefits
▪ Wireless. The Daikin external room thermostat is available in a
wireless version.
▪ Efficiency. Although the external room thermostat only sends ON/
OFF signals, it is specifically designed for the heat pump system.
▪ Comfort. In case of underfloor heating, the wireless external room
thermostat prevents condensation on the floor during cooling
operation by measuring the room humidity.

▪ 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.

Value
0 (Single zone): Main
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.

Configuration
Setting
Unit temperature control:
▪ #: [2.9]
▪ Code: [C-07]
Number of water temperature
zones:
▪ #: [4.4]
▪ Code: [7-02]
External room thermostat for the
main zone:
▪ #: [2.A]
▪ Code: [C-05]
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.

▪ 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.

thermostat): Unit operation is
decided by the external
thermostat.
