• Status: 19.10.2016 • Errors excepted. Subject to technical changes.
For dual-level dehumidification, the setpoint value difference between the two levels
must be defined, i.e. the setpoint value which, when exceeded, triggers the switch-on
of 2nd level.
Determine the deviation from the setpoint 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 controller responds to deviations from the set-
point value. In case of a short reset time, the control responds with a fast increase of
the control variable. In case of a long reset time, the control responds somewhat less
urgently and needs longer until the necessary control variable for the setpoint value
deviation is reached.
You should set the time appropriate for the humidification/dehumidification system at
this point (note manufacturer instructions).
Now specify what should be sent when the control is blocked.
On release, the control variable follows the rule again.
6.18. Variable comparator
The integrated variable comparators can output maximum, minimum and average
values.
6.18.1. Control variable comparator 1/2/3/4
Determine what the control variable comparator should output, and activate the input
objects to be used. Transmission patterns and blocks can also be set.
