Group objects
No.
18
This group object is enabled if the parameter Switch fan speed via 1-bit objects is set to Switch off to active
fan speed using "0" only or Switch off to any 1 bit fan speed using "0" in the Fan speed parameter window.
The fan changes to the corresponding speed when a 1 is sent on this group object.
The reaction on sending a 0 depends on the selection of the parameter Switch fan speed via 1 bit group
objects:
•
•
19
See group object 18
This group object is hidden if only a 1-speed fan was selected.
20
See group object 18
This group object is hidden if only a 1- or 2-speed fan was selected.
21
This group object is always enabled.
This group object sets the fan speed directly.
The speeds are controlled via the following values for a 3-speed fan:
•
•
•
•
The speeds are controlled via the following values for a 2-speed fan:
•
•
•
The speeds are controlled via the following values for a 1-speed fan:
•
•
22
This group object is always enabled.
With this group object, the fan can be switched one fan speed further up or down via a 1 bit telegram.
This can be done until the maximum or minimum fan speed is reached. The parameterized limitations are
taken into account here. Further UP or DOWN telegrams are ignored and not executed.

Function
Switch speed 1
When Switch off to active fan speed using "0" only is selected, a 0 switches off the fan only if the fan is
running at this fan speed. If not, reception has no effect.
When the option Switch off to any 1 bit fan speed using "0" is selected, receiving a 0 always switches the
fan off.
