Meaning
Professional setting for
modifying the controller
behaviour for the room.
Large values result in less
dramatic changes in the
control values when the
control deviation remains
the same, and gives more
precise control than lower
values.
The integration time
determines the response
time of the control.
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.
