6.3.1 Troubleshooting
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 status LED flashes orange and the boiler initially
continues controlled operation.
ERROR
In case of errors, the status LED flashes red, the boiler follows shutdown
procedure and remains in operating status "Off ", until the error is
resolved.
After troubleshooting, the boiler switches back to the operating status
"Off".
ALARM
An alarm triggers a system emergency stop. The status LED flashes red,
the boiler switches off immediately and the heating circuit controller and
pumps remain active.
