5.4 Room limit
The following section is a general description for Room
temperature limitation.
The actual application might not have both limitation types.
This section is only relevant if you have installed a room
temperature sensor or a Remote Control Unit for utilizing the room
temperature signal.
In the following description is referred to "flow temperature" in
general.
The controller adjusts the desired flow temperature to compensate
for the difference between the desired and the actual room
temperature.
If the room temperature is higher than the desired value, the
desired flow temperature can be reduced.
The 'Infl. -max.' (Influence, max. room temp.) determines how
much the desired flow temperature should be reduced.
Use this influence type to avoid a too high room temperature. The
controller will allow for free heat gains, i.e. solar radiation or heat
from a fire place etc.
If the room temperature is lower than the desired value, the desired
flow temperature can be increased.
The 'Infl. -min.' (Influence, min. room temperature) determines
how much the desired flow temperature should be increased.
Use this influence type to avoid a too low room temperature. This
could e.g. be caused by windy surroundings.
A typical setting will be -4.0 for 'Infl. -max.' and 4.0 for 'Infl. -min.'
Parameters indicated with an ID no. like "1x607" mean a universal
parameter.
x stands for circuit / parameter group.
MENU > Settings > Room limit
Adapt. time (adaption time)
1x015
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
value:
The desired room temperature is adapted quickly.
Major
value:
The desired room temperature is adapted slowly.
The adaptation function can correct the desired room temperature
with max. 8 K x heat curve slope value.
