Changing the Heating Curve
Your system’s heating characteristics are affected by the
slope and the level of the selected heating curve. Further
information about the heating curve can be found under
“Terminology” on page 40.
Factory setting:
H Slope: 1.4
H Heating curve level: 0
H Standard room temperature (set value): 68°F (20ºC)
H Reduced room temperature (set value): 65°F (18°C)

3. Select the heating circuit if necessary (see page 16)
4. “Heating curve”
5. “Slope” or “Level”
Note: Tips on when and how to change the heating
curve slope and level are displayed by pressing ? .
6. Set the required value
Example:
Change the heating curve slope to 1.5.
A graph clearly shows the change in the heating curve
as soon as you alter the value for the slope or level.
Depending on various outside temperatures (shown on
the horizontal axis), the assigned set flow temperatures
for the heating circuit are highlighted white.
