These are temporary alarms that if they occur 6 times in an hour they become definitive; the E097 alarm is displayed and
is followed by post-purging for 45 seconds at the fan's maximum speed.
It is not possible to release the alarm before the end of the post-purging unless the boiler's power supply is switched off.
These are temporary alarms that if they occur several times in an hour they become definitive; the last error to occur is
displayed and is followed by a post-purging of 5 minutes at the fan's maximum speed.
It is not possible to release the alarm before the end of the post-purging unless the boiler's power supply is switched off.
These are temporary faults that restrict the ignition cycle.
Temporary fault signalled during pre-purging. Post-purging is maintained for 5 min at maximum fan speed.
