page53.
# Code Description
[3.7] [2‑0D] Emitter type
▪ 0: Underfloor heating
▪ 1: Fancoil unit
▪ 2: Radiator
The setting of the emitter type has an influence on the space heating
setpoint range and the target delta T in heating as follows:
Emitter type
Additional zone
Space heating
setpoint range
[9‑05]~[9‑06]
Target delta T in
heating [1‑0C]
0: Underfloor heating Maximum 55°C Variable (see [2.B])
1: Fancoil unit Maximum 55°C Variable (see [2.B])
2: Radiator Maximum 65°C Fixed 10°C

# Code Description
Leaving water temperature range for the additional leaving water
temperature zone (= the leaving water temperature zone with the
highest leaving water temperature in heating operation)

37°C~65°C
▪ Else: 37°C~55°C
Control
The control type is displayed here, but cannot be adjusted. It is
determined by the control type of the main zone. For more info about
the functionality, see "8.4.3Main zone"on page53.
# Code Description
[3.9] N/A Control
▪ Leaving water if the control type of the
main zone is Leaving water.
▪ External room thermostat if the control
type of the main zone is External room
thermostat or Room thermostat.
Thermostat type
Only applicable in external room thermostat control. For more info
about the functionality, see "8.4.3Main zone"on page53.
# Code Description
[3.A] [C‑06] External room thermostat type for the
additional zone:
▪ 1: 1 contact. Connected to only 1
digital input (X2M/35a)

8.4.5 Space heating
About space operation modes
This unit is a heating only model. The system can heat up a space,
but NOT cool down a space.
Operation range
Depending on the average outdoor temperature, the operation of the
unit in space heating is prohibited.
