Operating modes
Volume flow control (VAV or CAV)
Variable air volume (VAV) control: the operating point is determined by the setpoint value
and the Vmin / Vmax settings (cf. diagram below). Constant air volume (CAV) control is
achieved by sending a constant setpoint or by setting Vmin = Vmax.
1 Setpoint range
2 Actual value range
3 Controlled area
Position control
The VAV compact controllers can be operated as damper actuators, i.e. using the 0..100%
setpoint as position damper setpoint, by setting the operating mode parameter to “POS”.
Commissioning and parameterization
Parameterization of the VAV application
VAV application parameters are set by the OEM over the PPS2 interface (using ACS931 or
AST20). Some of them can be adjusted during commissioning, operation, or maintenance
and are accessible over a bus connection alternatively.

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”.

Device jammed 03 00 0A 03 0C 05 Target position can’t be
reached due to blockage.
Remove blockage (visual
inspection required) or

Or switch on adaptive
positioning, if mechanical
limits are intended.
Backup mode

Actuator leaves Backup
mode when receiving a
setpoint.

00 01 0A 01 0C 05 Malfunction of internal
communication to dp sensor
(200 ms timeout)

3) replace device
Operating hours
notification
00 01 0A 04 0C 05 Appears after a cumulated

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.
