Prerequisite for commissioning (KNX PL-Link)
The room automation station must be running and an application must be loaded.
The application is not loaded on the room operator unit, but the room automation
station.
Download of the application is done using the SSA-DNT (Pack & Go) or the ABT.
For this purpose (or for service), connect the ABT to the room automation station
(USB or Ethernet).
Manual commissioning (KNX PL-Link)
All commissioning work is done via the room automation station, using the SSA-
DNT or the ABT.
The ABT is never connected directly to a room operator unit.
Addressing
When more than one QXM3.P... room operator unit is on the same trunk of the
KNX PL-Link bus, manual commissioning is done as follows:
1. Connect the SSA-DNT or the ABT to the room automation station and activate
the online commissioning function.
2. Load the web page "KNX PL-Link identification".
Activate the identification function.
The room automation station now waits for a signal from the room operator
unit.
3. On the room operator unit, simultaneously press the upper left and bottom
right button for at least 5 seconds (keys 1 and 8).
4. The "Engineering" page is displayed.
5. Press "Prog. Mode" (Key 2).
The display changes from "DISA" to "EnAB".
The tool identifies the current room operator unit that is operated and assigns
it.
6. After the device is commissioned, reset the device to programming mode to
“disabled” by pressing key 2.
Note: Programming mode resets to “disabled” each time the device restarts.
Connection test
1. Press "Conn. Test" (key 3) to test the KNX PL-Link connection.
The display shows the result of the connection test:
2. Press key 8 to return to the engineering page.
Reset to factory setting
Press "Fact. Reset" (Key 4). The device is locked and reboots within 10 seconds.
The room automation station deletes it from its device list. During this time, it is
safe to remove the device from the network.
If the bus plug remains connected, the device acts like a newly inserted device
requiring again automated or manual configuration.
Note! This operation resets all user preference data and
configuration settings to factory default.
This operation is irreversible.

– If the test is positive, the LED goes on continuously.
– If the test fails, it flashes (1 s on, 1 s off).
2. Short press the programming pin (<0.5 s) to stop displaying the result of the
connection test. The service LED goes off.
Long press the programming pin (>20 s). The device is locked and reboots within
10 seconds. The room automation station deletes it from its device list. During this
time, it is safe to remove the device from the network.
Note: there is no LED activity during this operation.
If the bus plug remains connected, the device acts like a newly inserted device
requiring again automated or manual configuration.
This operation resets all user preference data and configuration settings to
factory default.
This operation is irreversible.

*) Notes on CO
2
sensor
• Function: The sensor determines the CO
2
concentration via infrared absorption measurement (NDIR). The sensor is maintenance
free in normal environments, thanks to the built-in self-correcting ABC (Automatic Baseline Correction) algorithm. This algorithm keeps
track of the sensor’s lowest reading within 8 days and corrects for any drift detected. The sensor also contains self-diagnostics to
assure proper operation during lifetime.
• Use: Normal environments, such as offices, class rooms, hotel rooms, or other non-permanently occupied areas, typically reach at
least once a week the CO
2
concentration of fresh air of 400 ppm. However, exposure to a lowest CO
2
concentration other than fresh
air, or incorrect altitude parameter setting, might result in reduced accuracy and incorrect operation.
• Rough handling during transport, storage or mounting might adversely affect accuracy during the first days of operation.
• The specified accuracy is reached after 25 days of continuous operation.
