Main LWT zone
[4.4]

▪ 1:
Dual zone
Two leaving water temperature zones.
The main leaving water temperature
zone consists of the higher load heat
emitters and a mixing station to
achieve the desired leaving water
temperature. In heating:

Mixing station
NOTICE
NOT configuring the system in the following way can cause
damage to the heat emitters. If there are 2 zones, it is
important that in heating:
▪ the zone with the lowest water temperature is
configured as the main zone, and
▪ the zone with the highest water temperature is
configured as the additional zone.
NOTICE
If there are 2 zones and the emitter types are wrongly
configured, water of high temperature can be sent towards
a low temperature emitter (underfloor heating). To avoid
this:
▪ Install an aquastat/thermostatic valve to avoid too high
temperatures towards a low temperature emitter.
▪ Make sure you set the emitter types for the main zone
[2.7] and for the additional zone [3.7] correctly in
accordance with the connected emitter.
NOTICE
An overpressure bypass valve can be integrated in the
system. Keep in mind that this valve might not be shown
on the illustrations.

Configuration wizard: Backup heater
The backup heater is adapted to be connected to most common
European electricity grids. If the backup heater is available, the
voltage, configuration and capacity must be set on the user
interface.
The capacities for the different steps of the backup heater must be
set for the energy metering and/or power consumption control
feature to work properly. When measuring the resistance value of
each heater, you can set the exact heater capacity and this will lead
to more accurate energy data.
Backup heater type
The backup heater is adapted to be connected to most common
European electricity grids. The type of backup heater must be set on
the user interface. For units with a built-in backup heater, the type of
heater can be viewed but not changed.

▪ 2:
400V, 3ph
Configuration
The backup heater can be configured in different ways. It can be
chosen to have a 1-step only backup heater or a backup heater with
2 steps. If 2 steps, the capacity of the second step depends on this
setting. It can also be chosen to have a higher capacity of the
second step in emergency.

INFORMATION
Settings [9.3.3] and [9.3.5] are linked. Changing one
setting influences the other. If you change one, check if the
other is still as expected.
INFORMATION
During normal operation, the capacity of the second step of
the backup heater at nominal voltage is equal to
[6‑03]+[6‑04].
INFORMATION
If [4‑0A]=3 and emergency mode is active, the power
usage of the backup heater is maximal and equal to
2×[6‑03]+[6‑04].
