Influence

The 'Infl. - max.' and 'Infl. - min. ' determine how much the room / duct
temperature should influence the desired flow / duct temperature.
If the 'Infl. ' factor is too high and / or the 'Adapt. time' too low, there is
a risk of unstable control.
Example 1 (application with heat curve value):
The actual room temperature is 2 degrees too high.
The 'Infl. - max. ' is set to -4.0.
The heat curve slope is 1.8 (see 'Heat curve' in 'Flow temperature').
Result:
The desired flow temperature is changed by (2 x -4.0 x 1.8)
–14.4 degrees.
Example 2 (application, no heat curve value):
The actual room temperature is 3 degrees too high.
The 'Infl. - max. ' is set to -4.0.
Result:
The desired flow temperature is changed by (3 x -4.0)
-12 degrees.
Example 1 (application with heat curve value):
The actual room temperature is 2 degrees too low.
The 'Infl. - min. ' is set to 4.0.
The heat curve slope is 1.8 (see 'Heat curve' in 'Flow temperature').
Result:
The desired flow temperature is changed by (2 x 4.0 x 1.8)
