"Decentral bus power supply" operating line
For small plants, decentralized bus power supply suffices. This is the factory
setting.
Main menu > Commissioning > Communication > Basic settings >
Operating line Range Factory setting
Decentral bus power supply Off, On On
See data sheet N3127 (KNX bus) or basic documentation P3110 (KNX
communication) for more information.
If there is no bus supply, fault message "No bus power supply" appears.
No. Text Effect
5000 No bus power supply Non-urgent message; must not be
acknowledged
"Clock time operation" operating line
If a common clock time is to be used in the system, one device must be defined as
masters, all other devices as slaves.
Main menu > Commissioning > Communication > Basic settings >
Operating line Range Factory setting
Clock time operation Autonomous, Slave,
Master
Autonomous
Remote setting clock slave Yes, No Yes
When set to "Autonomous", the device neither sends nor receives the clock time.
Setting "Remote setting clock slave" allows the user to set the time and date at the
clock time slave.
The new values are then sent to the clock time master via KNX bus. The master
sends the new time to all bus members. Thus, operation for the user is the same
as with the clock time master.
"Remote reset of fault"operating line
Main menu > Commissioning > Communication > Basic settings >
Operating line Range Factory setting
Remote reset of fault Yes, No No
"Remote reset of fault = "Yes" means that all self-held fault messages can also be
reset via KNX bus, e.g. via RMZ792 bus operation, operator station via OCI700.1
or OZW775 central station.
If "No" is set, resetting must occur locally on the device via the fault
acknowledgement button.
28.2.2 "Room" menu item (basic types A, P, and C)
A geographical zone combines buildings or building sections that must satisfy the
following criteria from an operational point of view:
 Same room operating mode
 Same room temperature (setpoint, actual value)
Here, we can speak of operational zones rather then geographical zones.
