A heat distribution system (e.g. underfloor heating) is
dimensioned for a maximum flow temperature at a particular
standard external temperature. This is dependent on the location
of the heat pump and is between -12 and -18 °C in Germany.
The max. return temperature that is set on the heating controller
must be entered for an external temperature of –20 °C. This is
done by entering the maximum return temperature for the given
standard external temperature in Fig. 7.2 on p. 23. The setting at
–20 °C can be read using the set of curves.

NOTE
Step 1:
Adjust the heating curve to suit the respective building and local
conditions by setting the gradient (heating curve end point).
Step 2:
Set the desired temperature level via a parallel shift of the heating curve
upwards or downwards (indicator bar).
