(not present on IS models)
boiler proceeds with regular auton-
omous operation.
If, however, the boiler does not be-
gin regular operations, a definitive
lockout can be brought about.
In this case, proceed as described in
point 2.
2) Red led comes on and flashing
alarm code is displayed
Turn the mode selector to
and
reposition it on the desired posi-
tion.
If the boiler performs the firing pro-
cedure and resumes normal operation,
the stoppage can be attributed to a
chance situation.
If the shut-down reoccurs however,
you should contact the Technical As-
sistance Service.
For AL41 faults
Check the value of the pressure on the
hydrometer on the control panel; if it
is less than 0.5 bar proceed as follows:
Position the mode selector to
fill slowly by opening the filler tap
until the hand of the hydrometer is
between 1 and 1.5 bar
for IS models: fill the system until the
pressure on the hydrometer is be-
tween 1 and 1.5 bar
Reposition the mode selector to the
desired position.
If the drop in pressure is frequent,
contact the Riello Technical Assistance
Centre.
For fault AL60
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 temper-
ature of around 50°C.
The intervention of the Riello Technical
Assistance Centre is required.
