Wireless external room thermostat
▪ The under floor heating or radiators are directly connected to the
indoor unit.
▪ The room temperature is controlled by the wireless external room
thermostat (optional equipment EKRTR1).
Configuration
Setting
Value
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.2.2.4]
▪ 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
▪
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 under floor heating, the wireless external
room thermostat prevents condensation on the floor during cooling
operation by measuring the room humidity.

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/1 and X2M/4)
▪ The space operation mode is sent to the heat pump convectors by
one digital output on the indoor unit (X2M/32 and X2M/33).
INFORMATION
When using multiple heat pump convectors, make sure
each one receives the infrared signal from the remote
controller of the heat pump convectors.

1 (Thermo ON/OFF): 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: 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.
