Minimum dwell period in fan speed
in s [0...65,535]
This parameter defines the dwell time for a fan speed of the fan until it switches to the next higher or lower
fan speed. The input is made in seconds.
A setting of 0 means instant switching. Minimum relay switching times can be found in Technical data, p.
11 ff.
The dwell time is only taken into account in automatic operation.
Number of control value inputs
This parameter defines the number of control value inputs (communication objects) for automatic
operation.
1: There is only one Control value communication object.
2: There are two communication objects – Control value A and Control value B.
Dependent parameter:
Select by...
communication object "Toggle control value A/B"
This parameter sets how the blower actuator selects which control value (A or B) to use.
communication object "Toggle control value A/B": The control value to use is selected via the
communication object.
Largest value: The largest control value is always selected. If the values are equal (but not
zero), the input which was the latest to receive a value is selected.
