domestic hot water is still available.
▪ auto SH reduced/DHW off, space heating is reduced and
domestic hot water is NOT available.
▪ auto

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
If a heat pump failure occurs and Emergency is not set to
Automatic (setting 1), 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.
NOTICE
An overpressure bypass valve can be integrated in the
system. Keep in mind that this valve might not be shown
on the illustrations.
