To restore operation (deactivate alarms):
Faults A 01-02-03
Position the function selector to
set it to the required position
mode). If the reset attempts do not reactivate the boiler, contact the
Technical Assistance Centre.
Fault A04
In addition to the fault code, the digital display shows the symbol
Check the pressure value indicated by the water gauge:
if it is less than 0.3 bar, position the function selector to
and adjust the filling tap (B - fig. 10) until the pressure reaches a
value between 1 and 1.5 bar.
Then position the mode selector to the desired position
mer) or (winter).
If pressure drops are frequent, request the intervention of the Tech-
nical Assistance Service.
