Room target values
Room temperature
The room temperature can be set
according to different target values.
These target values come into
effect with the selected operating
mode, thereby resulting in different
temperature levels in each of the
rooms. The range of target values that
can be set is limited by their mutual
dependence, which can be seen in the
accompanying graphic illustration.
Frost protection
During protected mode operations,
a too strong lowering of the room
temperature is automatically prevented.
The heating unit will be automatically
set to the room temperature target
value for frost protection.
A variety of functions is available and
can be individually set for each heating
circuit.
Characteristic heating curve
The inlet temperature target value is
set by means out of the characteristic
heating curve, for which an inlet
temperature is set that depends on
the actual weather conditions. This
characteristic heating curve can be
modied by means of various settings,
so that the heating performance and
the room temperature conform to the
personal requirements.
