If group object #3 "fault transmission" is set to "on", the following faults can be transmitted if they
occur. In that case, group object #2 value changes to "alarm".

notification
Indicates whether the actuator is in fault state. If yes, read out group object #1.
Enabling/ disabling the fault transmission. Fault transmission is disabled by default; therefore no
faults are transmitted from the actuator over the KNX bus.
Setpoint 0...100% for volume flow or position, depending on the operating mode.
Relative damper position 0...100%. An opening range less than 0...90° can be normalized to
0...100% if adaptive positioning is set to "on".
Volume flow relative to the settings of Vnom, Vmin, and Vmax.

Volume flow in m
/h or m
/s depending on the selected data type.
Same function as group object #2 (available for compatibility reasons).
Indicates whether the VAV controller is in override control either by a programming tool connected to
the HMI or by objects #10 / #11.
When the object is triggered, the actuator drives to the override position 1 defined by the respective
ETS parameter.
When the object is triggered, the actuator drives to the override position 2 defined by the respective
ETS parameter.
When the object is triggered, the actuator drives to Vmax for air balancing purposes.
Minimum air volume flow relative to Vnom.
Maximum air volume flow relative to Vnom.
Nominal air volume flow (absolute).
Opening direction of the air damper.
Actual value of the differential pressure over the VAV box measuring cross.
VAV box characteristic value to map a nominal differential pressure to the corresponding nominal
volume flow.
Resets all parameters to the value specified by the OEM.
Description
Target position can't be
reached due to blockage.
Actuator is in backup mode
(cf. respective parameter
setting)
Pressure sensor measures
the lower pressure on the
input marked with "+".
Malfunction of internal
communication to dp sensor
(200 ms timeout)
Appears after a cumulated
motor running time of 365
days
Resolution
Remove blockage (visual
inspection required) or
invert Opening direction,
if it is set wrongly
Or switch on adaptive
positioning, if mechanical
limits are intended.
Actuator leaves Backup
mode when receiving a
setpoint.
Correct the tubes
connection
1) Check tubes
connection, or
2) reboot device, or
3) replace device
Check device status and
control loop sensitivity
