7.1.1 System data menu
Settings for the entire heating system can be made in this
menu. For example, the value for the minimum outside
temperature or the thermal storage capacity of the heated
building. Additional settings for heating circuit 1 and DHW
system 1 are available in this menu (if directly installed at the
heat source).
Settings in

Minimum outside temperature
The minimum outside temperature is the average value of each
of the coldest outside temperatures or recent years, and it has
an influence on the heating curve. The value for the region can
be taken from the required heat load calculation that should be
done for every building or from the climate zone chart or from
Tab. 17.
▶ Set the minimum outside design temperature for the
heating system (UK default is -3 °C).

No low loss header is installed
At the boiler
Low loss header installed, temperature sensor connected to heat source (boiler)
At the module
Low loss header installed, temperature sensor connected to module (i.e. MM 100/

Header w/o sensor
Low loss header installed, no temperature sensor is connected. If a heat requirement is
present, the heating pump is in permanent operation.

Internal boiler pump serves also as pump in heating circuit 1
Own pump
Heating circuit 1 is supplied by a dedicated heating pump (connected to heating
appliance or module (MM 100/MM 200))

None
The heat source pump serves as a heating circuit pump.
System pump
The pump in the heat source must be running for every heat requirement. If a low loss
header is present, the internal pump is always a system pump.

Damping
Yes
The set building type affects the measurement of the outside temperature. The outside
temperature influence is delayed (dampened) depending on insulation levels of the
building.
No
The measured outside temperature influence is not delayed and its impact on meeting
the target room temperature is immediate in weather compensation mode.
