3.11.8 Fault function on KNX

If a fault occurs (e.g. digital fault input, dew point, communication configuration,
etc.) then a fault will be sent on the bus.
An RDG thermostat listens on the bus and sends its fault when the fault has the
highest alarm priority. This ensures that the management station does not miss any
alarms.
If alarms occur at the same time, the alarm with the highest priority will be first
displayed and sent on the bus.
Fault transmission is different in LTE mode and S-mode:

*) Default alarm texts are stored in the thermostat's non-volatile memory and can
be adjusted using the ACS700 commissioning tool
**) This error will not be sent on bus (because there is no bus!)
 Priority order is #1...7
 External faults #4...6: If faults are active, the display will show AL1, AL2, AL3,
alternating. On the bus, only the fault with the highest priority will be sent
A supervisor alarm system may command the thermostat to stop sending faults to
the bus via the communication object "Fault transmission" (disable / enable).
This has no impact on the local display of faults.
After a timeout of 48 hours, the sending of faults will automatically be enabled
again.
