HEATING CURVE
ADJUSTING THE HEATING CURVE STEEPNESS
With adjusting the heat curve steepness, the controller is tuned with the
building. For optimal controller operation, the right setting of the heat curve
steepness is very important.
The hydraulic scheme can be changed any time. This can be done as follows:
1 - In the base view turn the navigation button so long that you get to the
scheme preview. Then push and hold the button and the info button.
When the scheme number begins to flash, release the buttons. With rota-
tion of the navigation button select the desired scheme and confirm it with
pressing the navigation button.
2 - The hydraulic scheme can also be changed with parameter S1.1.
3 - You can retake the controller three step setup.
Restarting the three step procedure!
Unplug the controller from the power source. Press and hold the key info and
reconnect the power supply. When the controller restarts itself, the 3 step
procedure is activated.
Heating curve steepness tells us, what temperature is required for the heating bodies by
a determined outdoor temperature. The steepness setting depends on the heat system
type (floor, wall, radiator, convector heating) and insulation of the building.
If you have enough data, you can determine the heating curve steepness with a calcula-
tion, otherwise from experience, based from the evaluation of heating system dimension-
ing and building insulation.
The steepness is set correct, if the room temperature remains stable, even by large out-
door temperature changes.
Until the outdoor temperature remains above + 5 °C, you can adjust the day / night tem-
perature with keys on the room unit. If it gets colder in the building, while the outdoor tem-
perature is dropping, then the heat curve steepness is set to low - you should increase
the setting. If the object by low outdoor temperatures gets warmer, the heat curve steep-
ness needs to be decreased.
The maximum steepness increase/decrease should not be greater than 0,1 to 0,2 units at
one observation. At least 24 hours must expire between two observations.
Preferred settings of the heating curve steepness:
