The figure shows the possible heat curves of 0.1 to 4.0 for a
target room temperature of 20 °C. If, for example, heat curve
0.4 is selected, a flow temperature of 40 °C is maintained at
an outdoor temperature of -15 °C.

°C
If the heat curve 0.4 is selected and 21 °C is specified for the
target room temperature, the heat curve is then translated,
as shown in the figure. The heat curve is displaced accord-
ing to the value of the target room temperature along axis a
which is angled at 45°. At an outdoor temperature of -15 °C,
the control system provides a flow temperature of 45 °C.
