8 Configuration
▪ When Emergency is set to Manual and a heat pump failure
occurs, the domestic hot water heating and space heating stops.
To manually recover it via the user interface, go to the
Malfunctioning main menu screen and confirm whether the
backup heater and/or booster heater can take over the heat load
or not.
▪ Alternatively, when Emergency is set to:
▪ auto SH reduced/DHW
domestic hot water is still available.
▪ auto SH reduced/DHW off, space heating is reduced and
domestic hot water is NOT available.
▪ auto SH normal/DHW
normally but domestic hot water is NOT available.
Similarly as in Manual mode, the unit can take the full load with
the backup heater and/or booster heater if the user activates this
via the Malfunctioning main menu screen.
To keep energy consumption low, we recommend to set Emergency
to auto SH reduced/DHW off if the house is unattended for longer
periods.
# Code
[9.5.1] [4-06] ▪ 0: Manual
▪ 1: Automatic
▪ 2: auto SH reduced/DHW on
▪ 3: auto SH reduced/DHW off
▪ 4: auto SH normal/DHW off
INFORMATION
The auto emergency setting can be set in the menu
structure of the user interface only.
INFORMATION
If a heat pump failure occurs and Emergency is set to
Manual, the room frost protection function, the underfloor
heating screed dryout function, and the water pipe
antifreeze function will remain active even if the user does
NOT confirm emergency operation.
Number of zones
The system can supply leaving water to up to 2 water temperature
zones. During configuration, the number of water zones must be set.
INFORMATION
Mixing station. If your system layout contains 2 LWT
zones, you need to install a mixing station in front of the
main LWT zone.

# Code
[4.4] [7‑02] ▪ 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:
a Additional LWT zone: Highest
temperature
b Main LWT zone: Lowest temperature
c 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.
Glycol Filled system
This setting gives the installer the possibility to indicate whether the
system is filled with glycol or water. This is important in case glycol is
used to protect the water circuit against freezing. If NOT set
correctly, the liquid in the piping can freeze.
# Code
N/A [E-0D] Glycol Filled system: Is the system
filled with glycol?
▪ 0: No
▪ 1: Yes
