5.4 Device address for the OZW775 central
communication unit
The OZW775 central communication unit is factory-set with device address 150.
This address enables the central communication unit to communicate via the KNX
bus. We do not recommend changing device address 150.
The procedure for commissioning is described in the installation instructions, sheet
G5663 (enclosed in the device packaging). For further in formation refer to the
commissioning guide C5663 (PDF file on the CD enclosed with the device).
The OZW775 central communication unit can power the KNX bus.
The central communication unit must be set to "Decentral bus power supply = On"
or a central bus power supply must be available (see section 2.2).
Should it be necessary to change device address 150, then the following points
should be noted:
The OZW775 central communication unit does not incorporate a tool socket. The
manual assignment of addresses and "Programming mode" are only possible via
the following connection:
PC/laptop OCI700 interface
OZW775 on KNX bus.
If there are no couplers or IP routers, the factory-set area/line address 0.2 is used.
