Device address for RMZ792 bus operator unit
The RMZ792 bus operator unit is used for remote operation of up to 150 Synco
700 bus devices including OZW77x central communication units and RXB/RXL
room controllers in a KNX network. Access to the bus devices is via the device list.
There is no access to Synco 900 type QAX910 central apartment units, area/line
couplers, IP routers or third-party devices.
The RMZ792 bus operator unit cannot be used to commission the Synco devices.
This is in contrast to the RMZ790 and RMZ791 operator units which can be used
for local commissioning of the Synco devices, but not for remote operation of other
Synco devices via the bus.
For more information on the RMZ792 bus operator unit, refer to data sheet N3113
and the basic documentation, P3113.
The RMZ792 bus operator unit does not power the bus.
Decentral or central bus power supply is required for communication via the KNX
bus (see section 2.2).
The bus operator unit is connected to an external AC 24 V power supply
(recommended for fixed operator units, e.g. installed in control panel doors).
The factory-setting is device address 255. For communication via KNX, this device
address must be modified.
If there are no couplers or IP routers, the factory-set area/line address 0.2 is used.
The individual device address can now be set.
