Remove devices from the device list

If you want to remove a device, select – whenever possible – function
"Disconnect device" (refer to page 58).
Sometimes, defective devices cannot be disconnected anymore. In
that case, you can remove the faulty device from the device list of the
central apartment unit as follows:
Main menu > Commissioning > Device list > Device X >
Delete device:
Use function "Delete device" only if you are unable to remove
the device with function "Disconnect device".

Bus communication

Device address KNX TP1

You need to enter an unambiguous device address for the central
apartment unit. After entry, the central apartment unit checks whether
the address entered has already been assigned. If the address is still
free, the display returns to the "Basic settings" menu. The value has
been adopted. Otherwise, you is prompted to enter a new address.

When using device address 255 (supply state), no data is
transmitted via bus. Use some other device address.

State whether the Konnex bus is powered by an external power pack
(bus power supply "Off") or whether the bus receives its power from
the central apartment unit (bus power supply "On").
