value depends on backup heater
configuration.

Configuration wizard: Main zone

The most important settings for the main leaving water zone can be
set here.
Emitter type
Depending on the system water volume and the heater emitter type
of the main zone, the heat up of the main zone can take longer. This
setting can compensate for a slow or a quick heating system during
the heat up cycle. The target delta T for the main zone will depend
on this setting. Target delta T control is only possible in case only 1
zone is active. Pump control will be different when both zones are
active.
In room thermostat control, this setting will influence the maximum
modulation of the desired leaving water temperature.
Therefore it is important to set this correctly and in accordance with
your system layout.
# Code
[2.7] [2‑0C] ▪ 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:
Description Space heating
setpoint range
0: Underfloor Maximum 55°C
heating
1: Fancoil unit Maximum 55°C
2: Radiator Maximum 65°C
NOTICE
For radiators, the average emitter temperature will be
lower compared to underfloor heating, due to the fixed
delta T of 10°C. To compensate, you can:
▪ Increase the weather
temperatures [2.5].
▪ Enable leaving water temperature modulation and
increase the maximum modulation [2.C].
Control
Define how the operation of the unit is controlled.
Control
Leaving water
Unit operation is decided based on the leaving
water temperature regardless the actual room
temperature and/or heating demand of the
room.
External room Unit operation is decided by the external
thermostat thermostat or equivalent (e.g. heat pump
convector).
Room thermostat Unit operation is decided based on the ambient
temperature of the user interface used as a
room thermostat.

Setpoint mode
In Fixed mode, the desired leaving water temperature does NOT
depend on the outdoor ambient temperature.
In Weather dependent mode, the desired leaving water
temperature depends on the outdoor ambient temperature.
# Code
[2.4] N/A Setpoint mode
▪ 0: Fixed
▪ 2: Weather dependent
When weather dependent operation is active, low outdoor
temperatures will result in warmer water and vice versa. During
weather dependent operation, the user has the possibility to shift the
water temperature up or down by a maximum of 10°C.
Schedule
Indicates if the desired leaving water temperature is according to a
schedule. Influence of the LWT setpoint mode [2.4] is as follows:
▪ In Fixed LWT setpoint mode, the scheduled actions consist of
desired leaving water temperatures, either preset or custom.
▪ In Weather dependent LWT setpoint mode, the scheduled
actions consist of desired shift actions, either preset or custom.
