Parameterization of the KNX integration
KNX integration parameters are checked or set during engineering and commissioning in the
ETS engineering tool.

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%
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).
ƒ
Backup position: Actuator drives to defined
position
ƒ
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

Hysteresis (COV)
4)
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
0...100%
Damper position which can be triggered by the
corresponding group object
0%
Override position 2
0…100%
Damper position which can be triggered by the
corresponding group object
100%
Write Vnom
On / Off
If checked, the group object for Vnom is writable
(OEM parameter protection applies), otherwise it
is read-only.
Off
Write Opening
Direction
On / Off
If checked, the group object for the opening
direction is writable (OEM parameter protection
applies), otherwise it is read-only.
