Return T Limit (Return Temp. Limitation) 4000; Limit (Return Temp. Limitation) 4030 - Danfoss ECL Comfort 110 Operating Manual

Maintenance
Return T limit (return temp. limitation)
The controller automatically changes the desired flow temperature to obtain an
acceptable return temperature when the return temperature falls below or gets higher
than the set limit.
Influence
This limitation is based on a PI regulation where P (Gain) responds quickly to deviations
and I (Intgr. time) responds slower and over time removes the small offsets between the
desired and actual values. This is done by changing the desired flow temperature.
If the 'Gain' is too high and / or the 'Intgr. time' too low, there is a risk of unstable control.
Limit (return temp. limitation)
Set the return temperature you accept for the system.
Set the acceptable return temperature limit.
When the return temperature falls below or gets higher than the set value, the controller
automatically changes the desired flow temperature to obtain an acceptable return
temperature. The influence is set in lines 4035 and 4036.
