Default alarm texts are stored in the thermostat’s non-volatile memory and can
be adjusted using the ACS commissioning tool.
2)
This error is not sent over the bus (because there is no bus, not enough bus
power supply, bus is overloaded or bus signal is distorted).
● Priority order is #1…7
● External faults #4…6: If faults are active, the display shows AL1, AL2, AL3,
alternating. Only the fault with the highest priority is sent over the bus.
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 is automatically enabled again.
