Description
Professional setting:
See in the Appendix: Response of
the PI controller
This time can be adapted to suit
particular circumstances. If the
heating system is over-
dimensioned and therefore too
fast, shorter values should be
used. On the other side, longer
integration times are beneficial
for a slightly undersized heating
(slow).
After what percentage change in
the actuating value is the new
value to be transmitted.
Small values increase control
accuracy but also the bus load.
How often should it be resent?
