12.3.2 Circuit 1 to 4 menu
Settings for each separate heating/cooling circuit are selected in this
menu. Here you can set the type of heating system installed for the
selected heating/cooling circuit. You can also set whether there is a
room controller or not, and which type of control mode to use. It is also
possible to optimise the heating/cooling circuit heating curves.
NOTICE:
Risk of damaging the screed!
▶ If an underfloor heating system is used, the max. flow
temperature recommended by the manufacturer of
the system should be observed.

Description
Heating circuit installed
No
A heating/cooling circuit is not installed. If there is no heating/cooling circuit installed, the heat pump
module is used for DHW heating only.
On the heat source
Electrical units and components in the selected heating/cooling circuit are directly connected to the heat
pump module (only possible with heating circuit 1).
At the module
Electrical units and components in the selected heating/cooling circuit are directly connected to a MM100
module.
Programming unit
HPC400
HPC400 independently regulates the selected heating/cooling circuit. No room controller installed.
CR10
CR10 installed as a room controller for selected heating/cooling circuit
CR10H
CR10H installed with humidity sensor as a room controller for selected heating/cooling circuit
ext. room temp. sensor
Yes
An extra room temperature sensor has been connected to the room controller (CR10 / CR10H). It enables
the control of a second circuit from the same room controller.
No
No additional room temperature sensor has been installed.

Adjusting the heating curve
Fine tuning the heating curve that has been preset through the heating system (
system and the heating curves for outside temperature compensated control, page 47)
Heat constantly below
Off
The heating operates independently from the adjusted outside temperature in the active operating mode
(
Constant heating below a certain outside temperature, page 49).
– 30 ... 10 °C
If the adjusted outside temperature goes down below this set value, the heating will automatically change
from setback mode to heating mode (
Constant heating below a certain outside temperature, page 49).
Frost protection
Instruction
: Set outside temperature controlled frost protection to ensure the frost protection of the
entire system. This setting is independent of the set operating mode.
Outside temp.
Frost protection is activated/deactivated depending on the temperature set here
