3. Appliance description
The device is responsible for the processes that control and regu-
late the heat pump. The appliance allows remote monitoring and
heating system control via the internet.
If several heat demands are present at the same time, the appli-
ance switches back and forth between them. If a booster heater
is activated, DHW heating can run at the same time as the heating
mode and swimming pool heating.

5.3 Network connection
Note
Please note that, for example, firewalls and faulty
connections may cause problems that prevent full
functionality.
If problems occur, contact your internet provider or
network administrator.
The device can be used to monitor the heating system via the
internet. For monitoring, you will need an internet connection,
a router and the Internet Service Gateway (ISG). Observe the ISG
operating and installation instructions. When using the ISG, use
the static IP address.
5.3.1 Connecting to the internet
Connect a patch cable to the RJ45 connector (see chapter
"Commissioning / Connecting to the internet" in the operat-
ing and installation instructions for the heat pump).
5.3.2 Network settings
Note
If multiple heat pumps are installed, the network
settings must be entered separately for each heat
pump.
Note
If settings are required on a router or other network
component, contact the network administrator.
The connection can be established via DHCP or a static IP address.
Ensure that you select the same connection for all heat pumps.
Press the button on the start screen to open the main
menu.
Press the button.
Select the "System settings" menu.
Select the "Network settings" menu.

1
The heat pump charges the buffer cylinder. The buffer
cylinder supplies the heating system via the mixing
valve. Overcharging the buffer cylinder is allowed. An
internal booster heater is allowed.
2
The heat pump charges the buffer cylinder. An unreg-
ulated external heat source (e.g. high capacity incin-
erator) charges the buffer cylinder. When the set tem-
perature according to the heating curve is reached,
the heat pump is switched off. The buffer cylinder
supplies the heating system via the mixing valve.
3
The heat pump charges the buffer cylinder. An ex-
ternally regulated second heat generator (e.g. high
capacity incinerator) charges the buffer cylinder via
a mixing valve managed by the internal control unit.
The buffer cylinder supplies the heating system via
the mixing valve. Overcharging the buffer cylinder is
allowed.
4
The heat pump charges the buffer cylinder. A regulat-
ed external second heat generator (e.g. high capacity
incinerator) provides heat directly to the heating
system via a mixing valve. The second heat generator
is controlled by the internal control unit of the heat
pump. The buffer cylinder is not charged by the sec-
ond heat generator. Overcharging the buffer cylinder
is allowed.
