With the buttons of the RDG room thermostats and Synco 700 devices, or the
RMZ790 / RMZ791 operator units, only the device addresses can be set. To set the
area and line addresses, the ACS790 software is required. The RXB / RXL room con-
trollers can be addressed via the ACS790 or via the Handy Tool QAX34.3.
Device addresses 254 and 255 are reserved for special functions. Communication is
deactivated via device address 255 (no exchange of process data).
When communication is activated, the effects are the following:
• Exchange of data required for heating and ventilation (e.g. demand for heat or cool-
ing energy, setpoints, etc.), provided the respective zone settings have been made
• Remote control of the devices can be effected via the KNX bus from an operator
station or a central station
• Fault status messages are always sent via the KNX bus and can be further handled
by other Synco devices
• Fault status messages from other Synco devices are displayed under Main menu >
Faults > Fault status message bus
• Fault status messages from other Synco devices can be delivered to a fault relay
