12.2.2 Immersion heater menu
Immersion heater settings are selected in this menu. This menu is only
displayed if an immersion heater has been set as an additional heat
source in the General settings menu for the booster heater.

Settings for heating/cooling
Fig. 38 Central heating settings menu
12.3.1 System data menu
System settings are selected in this menu. In this menu you can e.g. set
minimum outside temperature or the heat storage capacity. In this menu
you can further select settings for heating/cooling circuit 1 (if it is
directly connected to the heat pump module).
Minimum outside temperature
The lowest outside temperature is the average value of the coldest
outside temperatures of recent years, and it has an influence on the
heating curve. The value for the region can be borrowed from the VPW
calculation or the like.
▶ Set the lowest outside temperature for proportioning of the heating.

The booster heater max. heating output is limited in general to the value set here (2 | 3 | 4 | 6 | 9 | 12 |
15 kW).
Limit eff. DHW operation
mode
0 ... 15 kW
The booster heater max. DHW heating output is limited to the value set here (2 | 3 | 4 | 6 | 9 | 12 | 15 kW).
Outdoor temp. limit
When outside temperature is below the value set here, the booster heater can turn on.

If there is a buffer cylinder installed in the system, but
heating/cooling circuit 1 is without mixing valve:
▶ The temperature setting for VK1 determines the
highest temperature for all the circuits.
If there is a buffer cylinder installed in the system, and all
heating/cooling circuits have mixing valves:
▶ The circuit with the highest temperature setting
determines the highest temperature for all the
circuits.

Description
Storage cylinder
(Buffer cylinder)
Yes
There is a buffer cylinder installed in the system.
No
There is no buffer cylinder installed in the system. Heating/cooling circuit 1 is without mixing valve.
Config. VK1 on the heat
source
Heating/cooling circuit 1 is directly connected to the heat pump module as a heating circuit without mixing
valve.
No integrated VK1
This menu is shown if Yes was selected in the previous menu. Heating/cooling circuit 1 is not directly
connected to the heat pump module. In this case, a buffer cylinder must be installed in the system.
Heating/cooling circuit 1 has a mixing valve and are electrically connected to the system with a module.
Via circulation pump PC1
Heating/cooling circuit 1 is directly connected to the heat pump module and is without mixing valve with
or without buffer cylinder installed. The circulation pump PC1 in heating/cooling circuit 1 is electrically
connected to the heat pump module.

The lowest outside temperature influences the heating curve in outside temperature control mode
(
Minimum outside temperature, page 44 and Menu for setting the heating curve, page 47).
Damping
Yes
The set type of building will influence the measured outside temperature value. Outside temperature
influence is delayed (adjusted).
No
The measured outside temperature is not adjusted before it is sent to the outside temperature
compensated control.
Building type
Heat storage capacity of the heated building (
Heavy
High heat storage capacity and strong adjustment of the outside temperature, e.g. brick houses
Medium
Medium high heat storage capacity and medium strong adjustment of the outside temperature, e.g. hollow
concrete block houses
Light
Low heat storage capacity and weak adjustment of the outside temperature, e.g. prefabricated houses
and wood frame constructions
