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 2 minutes at the fan's maximum speed. It is not possible to release the alarm before the end of the post-purging
Temporary fault signalled during Pre-Purging. Post-Purging is maintained for 5 min at maximum fan speed.

DESCRIPTION OF TYPE OF ALARM
post-purging for 45 seconds at the fan's maximum speed.
It is always 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.

Error history
The ERROR HISTORY function is automatically enabled only after the machine has been
powered up for at least 2 consecutive hours, during this period of time any alarms that arise
would not be saved in the "error history". The alarms can be displayed in chronological
order, from the most recent to the oldest, up to a maximum of 50 alarms; to display the
error history:
- select TECHNICAL
INSTALLER
- for each alarms a sequential number is displayed, an error code and the date and time
the alarm occurred.
Note: Once enabled, the ERROR HISTORY function can no longer be disabled; there is no
procedure for resetting the error history.
If an alarm repeats consecutively, it is saved only once.
