4.2 Setting the heating/cooling
operating mode
Heating curve heating cycle mode
The heating curve can be adjusted in three points,
according to the structure and location-related con-
ditions of the building:
Base point:
The base point corresponds to the minimum set
temperature of the heating water at an outside
temperature of 20 °C. If the heating is too cold at
relatively high outside temperatures (trans-sea-
sonal period), the base point should be set higher.
Standard inlet temperature:
The standard inlet temperature corresponds to the
set temperature of the heating water at the
standard outside temperature in the building loca-
tion. If the heating is not warm enough at low out-
side temperatures, the standard inlet temperature
should be increased.
Standard outside temperature:
The standard outside temperature is dependent on
the regional location of the building and must be
set according to the region.

For optimal configuration of the heating curve
parameters, the heating load calculation and/or
energy consumption must be taken into account.
Differences between the installed parameters and
the design of the actual building can cause the
heat pump to run inefficiently.
