Ventilation control
Depending on the control mode, one and/or two setting sections for the ventilation
stages are displayed.
For two-stage ventilation, the target value difference between the two stages must be
defined, i.e. the target value which, when exceeded, triggers the switch to the 2nd
stage.
Determine the deviation from the target value at which the maximum variable value is
reached, i.e. the point at which maximum output is used.
The reset time shows how quickly the control responds to deviations from the target
value. In case of a short reset time, the control responds with a fast increase of the var-
iable. In case of a long reset time, the control responds somewhat less urgently and
needs longer until the necessary variable for the target value deviation is reached.
You should set the time appropriate to the ventilation system at this point (follow the
manufacturer's instructions).
Now determine what should be sent when the control is blocked.
On release, the control variable follows the rule again.
4.6.
Variable comparator
The two integrated control variable comparators can output maximum, minimum and
median values.
4.6.1. Control variable comparator 1/2
Determine what the control variable comparator should output, and activate the input
objects to be used. Send behaviour and blocks can also be set.
