[0-07] [0-06]
▪ T
t
: Target leaving water temperature
(additional zone)
▪ T
a
: Outdoor temperature
▪ [0-07]: Low outdoor ambient
temperature. 10°C~25°C
▪ [0-06]: High outdoor ambient
temperature. 25°C~43°C
▪ [0-05]: Desired leaving water
temperature when the outdoor
temperature equals or drops below the
low
ambient temperature.
[9‑07]°C~[9‑08]°C
Note: This value should be higher
than [0‑04] as for low outdoor
temperatures less cold water is
required.
▪ [0-04]: Desired leaving water
temperature when the outdoor
temperature equals or rises above the
high
ambient temperature.
[9‑07]°C~[9‑08]°C
Note: This value should be lower than
[0‑05] as for high outdoor
temperatures colder water is required.
Emitter type
For more info about this functionality, see "8.4.3 Main zone" on
page 47 .
# 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 8°C
Setpoint range
For more information about this setting, also see "8.4.3 Main
zone" on page 47 .
# 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 and the
lowest leaving water temperature in cooling operation)
[3.8.1] [9-05] Heating minimum: 15°C~37°C
# Code Description
[3.8.2] [9-06] Heating maximum
▪ [2‑0D]=2 (emitter type additional zone
= radiator)
37°C~60°C
▪ Else: 37°C~55°C
[3.8.3] [9-07] Cooling minimum: 5°C~18°C
[3.8.4] [9-08] Cooling maximum: 8°C~22°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 47 .
# 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 47 .
# 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)
▪ 2: 2 contacts. Connected to 2 digital
inputs (X2M/34a and X2M/35a)
Leaving water temperature: Delta T
For more information, see "8.4.3 Main zone" on page 47 .
# Code Description
[3.B.1] [1-0C] Delta T heating: A minimum temperature
difference is required for the good
operation of heat emitters in heating
mode.
▪ If [2-0D] = 2, this is fixed to 8°C
▪ Else: 3°C~10°C
[3.B.2] [1-0E] Delta T cooling: A minimum temperature
difference is required for the good
operation of heat emitters in cooling
mode.
▪ 3°C~10°C
8.4.5 Space heating/cooling
About space operation modes
Depending on your heat pump model, you have to tell the system
which space operation mode to use: heating or cooling.
If a … heat pump
model is installed
Then…
Heating/cooling The system can heat up and cool down a
space. You have to tell the system which
space operation mode to use.
Heating only The system can heat up a space, but
NOT cool down a space. You do NOT
have to tell the system which space
operation mode to use.
