Commissioning (KNX) 
The devices are equipped with a programming pin and a red service LED for KNX 
commissioning (see page 4).  
 
1.  Short press the programming pin (<0.5 s). 
The device goes into programming mode; the service LED is continuously on.  
The tool identifies the current room operator unit that is operated and assigns it. 
2.  After the device is commissioned, deactivate the programming mode by shortly 
pressing the programming pin (<0.5 s). The service LED goes off. 
 
Note: Programming mode resets to “disabled” each time the device restarts. 
 
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.  
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. 
Display and operation 
Operation and display of the room operator unit depend on the control 
program running on the room automation station.
