The alarm or alarms can also be viewed from the REG-DIN-8 display in the Information – Alarms//Bus Err. menu (see Annex I _ Parameter list).
The alarms could be a consequence of a bus error or not. In the second case, the Error bus light on the REG is off, while the red Alarm light is on. It is necessary to verify the cause (source in alarm, probe disconnected, overtemperature in the circuits, an OpenTherm generator in alarm, etc.). For those who have alarm notifications, they will receive an email with the active alarm.
Once the alarm has been resolved, the red light turns off without any further operations.
