Multiple VAV compact controllers can be connected simultaneously to the power
supply or individually. For Plug&Play commissioning, the PL-Link capable
controller must be preconfigured as per the recommended engineering and
commissioning workflow described in Technical Basics P3547.
The PL-Link controller is online.
The VAV compact controllers are not connected to the power supply.
Simultaneously connect all VAV compact controllers to the power supply (or
individually as applicable)
PL-Link controller and VAV compact controllers execute registration and
address assignment. Configuration is uploaded from the controller to the VAV
compact controllers.
Optional: Press middle key for connection test (>2 sec and <20 sec).
VAV compact controllers, KNX LTE-mode controller and operating units are
connected to the power supply; ACS790 is started.
In ACS790, open
Applications / Device list
…
a) Set a VAV compact controller to addressing mode
(Push button on device
LED shines red)
b) In ACS790, click button “
Programming mode
”
Address assignment
enter physical address
click
“Write”
or
a) Select a VAV compact controller from the device list by ID
(IDs are collected during mounting),
b) Double click the selected row to open the dialog box
“Address assignment”
,
Enter a physical address and short description for the selected VAV compact
controller,
Click
“Write”
to close dialog box,
Repeat steps for all VAV compact controllers for commissioning.
Continue: Further configuration with ACS790.
For KNX S-mode, the general S-mode commissioning procedures apply for ETS3
or ETS4. The HMI (push button and LED) conforms to the KNX standard.
Ordering through the VAV box manufacturer (OEM)
As a rule, documentation provided by VAV box manufacturers (OEM) contains
detailed information on VAV compact controller ordering information.
The OEM generally configures and assembles VAV compact controllers as VAV
box units. This facilitates commissioning at the construction site considerably. Use
service kit AST21 (PC software for service ACS941 and interface converter AST in
a transport case) should changes nevertheless be required on site.
OEM always sets
n
V
(nominal air volume flow) as a matter of principle.
