Device information


Basic settings


With access at the Service level, the setting values on the "Basic settings" page are read-only values. This is indicated by the fact that the black bar does not cover the whole operating line, i.e. the settings themselves are not highlighted.

In small networks, the KNX bus can be commissioned with the factory-set area address 0 (zero) and line address 2. These addresses are permissible only if:

  • The Synco bus devices are installed in Area 0 and Line 2 of a network, and not assigned to other areas and lines by means of super-ordinate area and line couplers.

Read other basic settings

The other basic settings under "Communication" can be read by rotating the knob clockwise.
