For further information on settings, operating modes, and engineering and
commissioning workflows in the available system environments, please refer to
"Technical Basics" P3547.
OEM generally provide the basic configuration to VAV compact controllers,
especially the parameter
were the VAV compact controllers are used (i.e. PL-Link, KNX LTE-mode, KNX S-
mode). Overall system engineering and commissioning is based on this basic
configuration; accomplished using tools listed under "equipment combinations"
(p. 2).
The following parameters must be checked or set prior to commissioning:

VAV compact controllers operate in VAV mode when connected to the specified
power supply. The setpoint signal determines the operating range

The VAV compact controllers can be operated in CAV mode by setting the setpoint
value accordingly.
