Parameterization of the KNX integration 
KNX integration parameters are checked or set during engineering and commissioning in the 
ETS engineering tool. 
Parameter 
Range 
Description 
Factory settings 
Tab card “standard” 
Operating mode 
VAV / POS  
VAV: setpoint = volume flow 0…100% 
POS: setpoint = damper position 0…100% 
VAV 
Adaptive positioning 
On / Off 
Adaption of actual (if mech. limited) opening range 
to position feedback 0...100% 
1)
Off = No adaption / On = Pos. adaption 
Off 
Altitude /  
Elevation asl. 
0…5000m 
in 500m steps 
Correction factor for diff. pressure sensor (select 
n*500m value closest to local altitude) 
500 m 
Backup timeout 
0..60 min 
0 min = disabled 
Time interval to detect communication 
interruption. If disabled, the actuator drives to the 
last received setpoint until a new setpoint is 
received. 
30 min. 
Backup mode 
Backup position  
Keep last position 
Actuator behavior when the communication 
timeout has been exceeded (no setpoint received 
within the defined time interval). 
▪ Backup position: Actuator drives to defined 
position 
▪ Keep last position: Actuator keeps position 
without flow control 
Backup position 
Backup position  
0…100% 
Position the damper drives to in case of 
communication interruption 
50% 
Tab card “advanced” 
Hysteresis (COV) 
volume flow 
1...20% 
Threshold for the relative volume flow.  
COV below this value are not sent over the bus. 
1% 
Min. repetition time 
volume flow 
10...900 s 
Minimum waiting time until a COV above the 
hysteresis threshold is sent over the bus 
10 s 
Hysteresis (COV) 
damper position 
1...20% 
Threshold for the damper position. COV below 
this value are not sent over the bus 
1% 
Min. repetition time 
damper position 
10...900 s 
Minimum waiting time until a COV above the 
hysteresis threshold is sent over the bus 
10 s 
Override position 1 
2)
0...100% 
Damper position which can be triggered by the 
corresponding group object 
0% 
Override position 2 
2)
0…100% 
Damper position which can be triggered by the 
corresponding group object 
100% 
Write Vnom 
On / Off 
If active, the group object for Vnom is writable 
(OEM parameter protection applies), otherwise it 
is read-only. 
Off 
Write Opening 
Direction  
On / Off 
If active, the group object for the opening direction 
is writable (OEM parameter protection applies), 
otherwise it is read-only. 
Off 
1)
Adaptation must not be activated while a device jam is present 
2) 
Override position 1 has priority over Override position 2
