Professional setting for
adapting controlresponse to
the room.
Large values cause finer
changes to the actuating value
with the same control
deviation and more precise
control than smaller values.
Integrated time of the cooling
control
Pure P control
15 min., 30 min., 45 min.,
60 min., 75 min.,
90 min.
,
105 min, 120 min, 135 min,
150 min, 165 min, 180 min,
195 min, 210 min, 225 min
Only for PI control:
The integrated time
determines the reaction time
of the control.
It lays down the increase that
the output control variable is
raised by, in addition to the P
share. The I- share remains
active for as long as there is a
control deviation. The I share
is added to the P share.
Sends the cooling control
variable
With change of 1 %
With change of 2 %
With change of 3 %
With change of 5 %
With change of 7 %
With change of 10 %
With change of 15 %
After how much % change*
in the control variable is the
new value to be sent.
Small values increase control
accuracy and also the bus
load.
Sends cooling actuating value
cyclically
Not cyclical, only in the
event of change
Every 2 min.
Every 3 min.
Every 5 min.
Every 10 min.
Every 15 min.
Every 20 min.
Every 30 min.
Every 45 min.
Every 60 min.
How often is the current
cooling control variable to be
sent (regardless of changes)?
