Emergency
When the heat pump fails to operate, the backup heater and/or
booster heater can serve as an emergency heater. It then takes over
the heat load either automatically or by manual interaction.
▪ When
Emergency
is set to
Automatic
and a heat pump failure
occurs, the backup heater automatically takes over the heat load,
and the booster heater in the optional tank takes over the
domestic hot water production.
▪ 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 on
, space heating is reduced but
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 off
, space heating operates as
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.

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.

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.
