Use the menu structure instead of the overview settings. 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?
In case of EKHWP, we recommend to use the following settings:

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
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.

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.
