means there is a breakdown in the flame
detection circuit; the boiler will stop and
the display will show anomaly “AL 08”.
– AU X I L I A RY S E N S O R E R R O R
ALARM 10
ONLY FOR BOILER WITH SOLAR PLANT
COUPLING (
PAR 2 = 10 or 14 ):
D.H.W. inlet probe anomaly. When the
probe is open or short circuited the boi-
ler looses the solar function and the
display shows anomaly AL 10.
– MODULATOR ERROR ALARM 11
The modulator is not connected.
When during functioning t he boiler
detects zero current to the modulator,
the display will show anomaly “AL 11”.
The boiler will function at minimum
power and the anomaly will be de-acti-
vated when the modulator is reconnec-
ted or when the burner stops working.
– CONFIGURATION ERROR ALARM 12
Anomaly in the SEALED/OPEN configu-
ration. There may be a conflict between
the values set by the installer for PAR 1
and the self-detection carried out by the
card causes the activation of the alarm:
the boiler will not function and the display
will show anomaly “AL 12”.
Reset PAR 1 to de-activate the alarm or
check the pressure switch/combustion
product thermostat and relative connec-
tion.
– HEATING PROBE POSITIONING
ANOMALY SM1/SM2 “AL 16”
(fig.
22/d)
If the probe does not detect a tempera-
ture increase after burner ignition, the
burner switches off after 10 seconds,
the display shows anomaly AL 16 eand
the4 green LED stays on.
If the anomaly occurs three times within
24h lthe boiler blocks, the display conti-
nues to show anomaly AL 16 and the red
LED switches on.
Press
on the control panel to re-start
the boiler.
– SENSOR ALIGNMENT ERROR “AL 17"
When the two sensitive elements of the
heating probe (SM1/SM2) dif fer to
each other by more than 16°C the boiler
does not function and the display shows
anomaly AL 17.
Re p l a c e
t h e h e a t i n g p r o b e
(SM1/SM2) to restore functioning.
