5.3 Duct T limit / Room limit
This section is only relevant if you have installed a duct / room
temperature sensor S4 or a Remote Control Unit for utilizing the
room temperature signal.
In the following description is referred to "flow temperature" in
general. This can be air duct or inlet temperature too.
The controller adjusts the desired flow temperature to compensate
for the difference between the desired and the actual duct / room
temperature.
If the duct / room temperature is higher than the desired value, the
desired flow temperature can be reduced.
The 'Infl. -max.' (Influence, max. duct / room temp.) determines
how much the desired flow temperature should be reduced.
Use this influence type to avoid a too high duct / room temperature.
The controller will allow for free heat gains, i.e. solar radiation or
heat from a fire place etc.
If the duct / room temperature is lower than the desired value, the
desired flow temperature can be increased.
The 'Infl. -min.' (Influence, min. duct / room temperature)
determines how much the desired flow temperature should be
increased.
Use this influence type to avoid a too low duct / 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.

*
Controls how fast the actual room / duct temperature adapts to the desired
room / duct temperature (I control).
* See Appendix “Parameter ID overview”
OFF:
The control function is not influenced by the 'Adapt.
time'.
Minor
value:
The desired room / duct temperature is adapted quickly.
Major
value:
The desired room / duct temperature is adapted slowly.
If your application key has a heat curve setting:
The adaptation function can correct the desired room temperature
with max. 8 K x heat curve slope value.
If your application key does not have a heat curve setting:
The adaptation function can correct the desired flow temperature
with max. 8 K.
