During the loading phase the scrolling message "SEMI-AUTOMATIC FILLING IN
PROGRESS" is displayed at the foot of the screen, while the pressure highlighted on the
display should start to rise. When the loading is finished the scrolling message "SEMI-
AUTOMATIC FILLING FINISHED" is displayed at the foot of the page. When the transitional
time has finished, if the fault persists the fault code E040 is displayed.
When the boiler has fault E040 manual loading should be carried out using the filler tap (A)
until the pressure is between 1 and 1.5 bar.
Then close the filling tap, making sure to hear the mechanical snap.
Only for installer: At the end of the procedure, proceed with the automatic vent cycle as
described in "2.9 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.

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.
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:

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.
