Parameterization of the KNX bus integration
The following parameters are usually checked and set by the systems integrator to achieve
the right level of bus traffic generated by the actuator or to define the behavior in case of
communication interruption. Parameters in the group “advanced” can be left unchanged
unless a special configuration is required.
Parameter group “Standard”:
Parameter
Range
Description
Factory setting
Backup timeout
0…60 min
0 min = disabled
Time interval to detect communication interruption.
If disabled, the actuator controls 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

Parameter group “Advanced”:
Parameter
Range
Description
Factory setting
Hysteresis (COV)
actuator position
1)
1...20%
Threshold for the actuator position. COV below this
value are not sent over the bus
1%
Min. repetition time
actuator 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%
Position to which the actuator drives if the associated
group object is triggered (override priority)
0%
Override position 2 0…100%
Position to which the actuator drives if the associated
group object is triggered (override priority)
100%
