Group Objects Description
1
Fault information
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”.
Error
Group obj. #1
Description
Resolution
Device jammed
XX 00 0A 03 0C 05
Target position can’t be
reached due to blockage.
Remove blockage (visual
inspection required) or
invert Opening direction if
it is set wrongly.
When done, switch on
adaptive positioning if
mechanical limits are
intended.
Backup mode
entered
XX 01 01 02 0C 05
Actuator is in backup mode
(cf. respective parameter
setting)
Actuator leaves Backup
mode when receiving a
setpoint.
Pressure sensor
tubes inverted
XX 01 0A 01 0C 05
Pressure sensor measures
the lower pressure on the
input marked with “+”.
Correct the tubes
connection
Pressure sensor
malfunction
XX 01 0A 01 0C 05
Malfunction of internal
communication to dp sensor
(200 ms timeout)
1) Check tubes
connection, or
2) reboot device, or
3) replace device
Operating hours
notification
XX 01 0A 04 0C 05
Appears after a cumulated
motor running time of 365
days
Check device status and
control loop sensitivity
2
Fault state
Indicates whether the actuator is in fault state. If yes, read out group object #1.
3
Fault transmission
Enabling/ disabling the fault transmission. Fault transmission is disabled by default; therefore, no
faults are transmitted from the actuator over the KNX bus.
4
Setpoint
Setpoint 0…100% for volume flow or position, depending on the operating mode.
5
Damper position
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”.
6
Volume flow relative
Volume flow relative to the settings of Vnom, Vmin, and Vmax.
7
Volume flow absolute
Volume flow in m
3
/h or m
3
/s depending on the selected data type.
8
Fault
Same function as group object #2 (available for compatibility reasons).
9
Overridden
Indicates whether the VAV controller is in override control either by a programming tool connected to
the HMI or by objects #10 / #11.
10
Override position 1
When the object is triggered, the actuator drives to the override position 1 defined by the respective
ETS parameter.
11
Override position 2
When the object is triggered, the actuator drives to the override position 2 defined by the respective
ETS parameter.
12
Balancing mode
When the object is triggered, the actuator drives to Vmax for air balancing purposes.
13
Vmin
Minimum air volume flow relative to Vnom.
14
Vmax
Maximum air volume flow relative to Vnom.
15
Vnom
Nominal air volume flow (absolute).
16
Opening direction
Opening direction of the air damper.
17
Diff. pressure
Actual value of the differential pressure over the VAV box measuring cross.
18
Coefficient
VAV box characteristic value to map a nominal differential pressure to the corresponding nominal
volume flow.
19
OEM-Reset
Resets all parameters to the value specified by the OEM.
