5.3 Faults with fault message
If a fault has occurred and has not yet been cleared:
❒
Status LED flashes red
❒ A fault message is shown on the display
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 opera‐
tion, giving the option of resolving the error quickly to prevent a
shutdown.
ERROR The boiler follows the shutdown procedure and remains in
"Switched off 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 re‐
main active.
