Adjusting the heating curve
The method described below can be used to adjust the heating curve correctly.
Adjustment if it is too cold indoors:
• If the outdoor temperature is lower than 0 degrees:
Increase the Inclination value by a couple of degrees.
Wait 24 hours to see if any further adjustment is required.
• If the outdoor temperature is higher than 0 degrees:
Increase the Adjustment value by a couple of degrees.
Wait 24 hours to see if any further adjustment is required.
Adjustment if it is too warm indoors:
• If the outdoor temperature is lower than 0 degrees:
Decrease the Inclination value by a couple of degrees.
Wait 24 hours to see if any further adjustment is required.
• If the outdoor temperature is higher than 0 degrees:
Decrease the Adjustment value by a couple of degrees.
Wait 24 hours to see if any further adjustment is required.

If the values set are too low, this may mean that the desired room temperature
is not being reached. You then need to adjust the heating curve, as necessary,
following the method shown above.
When the basic values have been set more or less correctly, the curve can
be finely adjusted directly using the Room temp. shown on the home menu
screen.
Appropriate Default Values
During installation you can seldom achieve a precise setting for the heating
curve instantly. In this case, the values given below may provide a good
starting point. Radiators with small heat-emission surfaces require a higher
primary flow temperature. You can adjust the gradient (heating curve
gradient) for your heating system under the "Installer / Settings / Radiator
system" menu.
Recommended values are:
Floor heating only Inclination 35
Low temperature system (well insulated houses) Inclination 40
Normal temperature system (factory setting) Inclination 50
High temperature system
(older houses, small radiators, poorly insulated) Inclination 60
