MENU > Settings > Room limit
Adapt. time (adaption time)
Controls how fast the actual room temperature adapts to the desired room
temperature (I control).
See Appendix "Parameter ID overview"
OFF:
The control function is not influenced by the 'Adapt.
time' .
Minor The desired room temperature is adapted quickly.
value:
Major The desired room temperature is adapted slowly.
value:
MENU > Settings > Room limit
Infl. - max. (room temp. limitation, max.)
Determines how much the desired flow temperature will be influenced
(decreased) if the actual room temperature is higher than the desired room
temperature (P control).
See Appendix "Parameter ID overview"
0.0:
No influence
-2.0:
Minor influence
-5.0: Medium influence
-9.9:
Maximum influence

The adaptation function can correct the desired room temperature
with max. 8 K x heat curve slope value.

# 1#
# 2 # = Negative influence (1x082) when actual room temp. gets higher
than desired room temp.
# 3 # = Positive influence (1x083) when actual room temp. gets lower than
desired room temp.
The 'Infl. - max.' and 'Infl. - min. ' determine how much the room
temperature should influence the desired flow temperature.
If the 'Infl. ' factor is too high and / or the 'Adapt. time' too low, there is
a risk of unstable control.
Example
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.
In application subtypes, where a heat curve slope value is not present,
the heat curve slope value is set to 1:
Result:
The desired flow temperature is changed by (2 x -4.0 x 1):
–8.0 degrees.
