Meaning
After what % change** in
the control value is the new
value to be sent?
Small values increase the
control accuracy, but also
the bus load.
how often does the current
heating control value need
to be sent (regardless of
changes)?
Professional setting for
modifying the control
behaviour for the room.
Small values result in large
changes in the control
values; larger values result
in a less dramatic change
in the control value.
See in appendix:
T emperature control
H U
The integration time
determines the response
time of the controller.
It specifies the increase by
which the output control
value is increased in
addition to the P-
component. The I-
component remains active
for as long as there is a
control deviation. The I-
component is increased by
the P-component.
