5.3 Faults with fault message
If a fault message is pending:
Status LED (4.1) indicates the type of fault:
- Orange flashing: warning
- Red flashing: error or alarm
The relevant fault message is shown on the display (4.2)
The term “fault” is a collective term for warnings, errors and alarms.
The boiler reacts differently to the three types of message:
WARNING In case of warnings the boiler initially continues controlled
operation, giving the option of resolving the error quickly to
prevent a shutdown.
ERROR The boiler follows shutdown procedure and remains in “Boiler
off” status until the problem is resolved.
ALARM An alarm triggers a system emergency stop. The boiler shuts
down immediately, the heating circuit controller and pumps
remain active.
