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 following functions will remain
active even if the user does NOT confirm emergency
operation:
- Room frost protection
- Underfloor heating screed dryout
However, the disinfection function will be activated ONLY if
the user confirms emergency operation via the user
interface.
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
A differential pressure bypass valve can be integrated in
the system. Keep in mind that this valve might not be
shown on the illustrations.
