The room temperature is controlled by the wireless external
room thermostat (optional equipment EKRTR1).

Unit temperature control:
#: [A.2.1.7]
Code: [C-07]

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.

Configure according to the setup:
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.
2 (C/H request): When the
used external room
thermostat can send
separate heating/cooling
thermo ON/OFF condition.
Heat pump convectors
Setup
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/1 and X2M/4).
The space operation mode is sent to the heat pump convectors
by one digital output on the indoor unit (X2M/33 and X2M/34).
INFORMATION
When using multiple heat pump convectors, make sure
each one receives the infrared signal from the remote
controller of the heat pump convectors.
