INFORMATION
By default, daylight savings time is enabled and clock
format is set to 24 hours. If you want to change these
settings, you can do this in the menu structure (User
settings > Time/date) once the unit is initialised.
5.2.3 Configuration wizard: System
Indoor unit type
The indoor unit type is displayed, but cannot be adjusted.
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.
# Code Description
[9.3.1] [E‑03] ▪ 3: 6V
▪ 4: 9W
Domestic hot water
The following setting determines if the system can prepare domestic
hot water or not, and which tank is used. This setting is read only.

▪ Integrated
The backup heater will also be used
for domestic hot water heating.
(*) Menu structure setting [9.2.1] replaces the following 3
overview settings:
[E-05] Can the system prepare domestic hot water?
[E-06] Is a domestic hot water tank installed in the system?
[E-07] What kind of domestic hot water tank is installed?
Emergency
When the heat pump fails to operate, the backup heater can serve
as an emergency heater and either automatically or non-
automatically take over the heat load.
▪ When auto emergency is set to Automatic and a heat pump failure
occurs, the backup heater will automatically take over the heat
load and the domestic hot water production.
▪ When auto emergency is set to Manual and a heat pump failure
occurs, the domestic hot water and space heating operation will
stop and need to be recovered manually via the user interface. To
recover operation manually, go to the Malfunctioning main menu
screen, where the user interface will then ask you to confirm
whether the backup heater can take over the heat load or not.
We recommend to set Emergency to Automatic if the house is
unattended for longer periods.
# Code Description
[9.5] N/A ▪ 0: Manual
▪ 1: Automatic
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.
# Code Description
[4.4] [7‑02] ▪ 0: Single zone
Only one leaving water temperature
zone:
a
▪ a: Main LWT zone
[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
CAUTION
If there are 2 zones, it is important that 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. Not configuring the
system in this way could cause damage to the heat
emitters.
CAUTION
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.
