Only for installer: At the end of the procedure, proceed with the automatic vent cycle as
described in “Filling the heating system and eliminating air”.

If the drop in pressure is very frequent, contact the Technical Assistance Centre.
For fault E060: the boiler is working normally, but does not provide any stability of the
domestic hot water temperature that, in any event, is supplied at a temperature of around
50°C. The intervention of the Technical Assistance Service is required.
For fault E091: the boiler has an auto-diagnostic system which, based on the total number
of hours in certain operating conditions, can signal the need to clean the primary exchanger
(alarm code E091). Once the cleaning operation has been completed, reset to zero the total
hour meter with special kit supplied as an accessory following procedure indicated below:

Note: The meter resetting procedure should be carried out after each in-depth cleaning of
the primary exchanger or if this latter is replaced.

List of combustion faults
ERROR CODE ERROR MESSAGE DESCRIPTION OF TYPE OF ALARM
E021 ACC monitor error
These are temporary alarms that if they occur several times in an hour they become definitive; the alarm E097 is displayed and is
followed by 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.
E022 ACC monitor error
E023 ACC monitor error
E024 ACC monitor error
E067 ACC monitor error
E088 ACC monitor error
E097 ACC monitor error
E085 incomplete combustion
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 unless the boiler's power supply is switched off.
E094 incomplete combustion
E095 incomplete combustion
E058 mains voltage fault
These are temporary faults that restrict the ignition cycle.
E065 current modulation alarm
E086 flue gases obstruction alarm Temporary fault signalled during Pre-Purging. Post-Purging is maintained for 5 min at maximum fan speed.
