domestic hot water tank is by default
installed. Do NOT change this setting.
[A.2.2.3] [E-07] During domestic hot water preparation,
the heat pump can be assisted by an
electrical heater to ensure the domestic
hot water preparation even for high
desired tank temperatures.
DHW tank type:
2 (Type 3)(default): The booster
heater will also be used for domestic
hot water heating.
[A.2.2.A] [D-02] The indoor unit offers the possibility to
connect a field supplied domestic hot

on the installation and configuration on
the user interface, we distinguish its
functionality.

disinfection. It runs when the
disinfection function of the domestic
hot water tank is running. No further
