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, in Germany, lies between -12 and -18 °C.
The maximum return temperature to be 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. 3.2 on p. 17. The
setting at -20 °C can be read using the 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).
