SIGNAL
Resetting the faults
Wait about 10 seconds before resetting nor-
mal operation conditions.
Then proceed as follows:
1 Display of the blinking alarm code
If just the blinking alarm is displayed it means
that a temporary stop was diagnosed, if the
fault is reset the boiler proceeds with regular
autonomous operation.
If, however, the boiler does not begin reg-
ular operations, a definitive lockout can be
brought about. In this case, proceed as de-
scribed in point 2.
2 Red led comes on and blinking alarm
code is displayed
Turn the mode selector (5) to and reposi-
tion it on the desired position.
If the boiler performs the firing procedure
and resumes normal operation, the stop-
page can be attributed to a chance situation.
If the shut-down reoccurs however, you
should contact the
r
Technical Assistance
Service.
For AL41 faults
Check the pressure on the hydrometer under
the boiler; if it is less than 0.5 bar proceed as
follows:
−
position the mode selector (5) to
1

− fill slowly by opening the filler tap
on the outside of the boiler until the
hand of the hydrometer is between 1
and 1.5 bar
filling
tap
−
reposition the mode selector (5) on
the required position (summer or
winter).
If pressure drop is frequent, contact the
r
Technical Assistance Service.
For fault AL60
The boiler is working normally, but does not
provide any stability of the domestic hot wa-
ter temperature that, in any event, is sup-
plied at a temperature of around 50°C.
The intervention of the
r
Technical Assis
-
tance Service is required.
