Number of control value inputs
Options:
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.
Activate monitoring control values
Options:
This parameter sets the monitoring for the control value input(s). Any remaining telegrams on the
communication object(s) are detected.

No: Control value monitoring is deactivated.

Yes: Control value monitoring is activated.
Dependent parameters:

Dependent parameter:
Select by...
Options: Communication object "Toggle control value A/B"
Largest value
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.
No
Yes
Monitoring time
in s [30...65,535]
Options: 30...120...65,535
This parameter sets the maximum time allowed between two control value telegrams. An error is
reported if this time is exceeded.
Note
The monitoring time should be at least twice as long as the cyclical transmission time of the
control value, so that the absence of a signal, e.g. due to a high bus load, does not immediately
trigger an error.
Where there are two control value inputs, the following additional parameter appears:
