Installation, electrical connection and operation 2.4 Commissioning Loading the physical address and application software The commissioning of the device is basically confined to programming of the physical address and the application data with the ETS. Configuring and commissioning of the device using the ETS3 (from version d with patch A) or using the ETS4.
Installation, electrical connection and operation 2.5 Operation The KNX bus coupler push-button (push-button BCU) fulfills the functions of a simple push- button. The device must be configured and put into operation using the ETS. In the unprogrammed delivery state, the device does not function. Only the status-LEDs of the rockers will be activated (see page 24).
