– HEATING SENSOR
ANOMALY "AL 05"
When C.H. sensor (SM) are open or
short circuited, the boiler will not func-
tion and the display will show the alarm
"AL 05".
– FLAME BLOCK
"AL 06" (fig. 22/b)
If the flame control has not detected the
presence of the flame after a complete
ignition sequence, or for any other rea-
son the card cannot "see" the flame, the
boiler will stop and the display will show
the alarm "AL 06".
Press the key of the controls to start
up the boiler again.
– SAFETY THERMOSTAT ANOMALY
"AL 07" (fig. 22/c)
Opening the connection line with the
security thermostat determines boiler
shutdown. The display shows AL 07 and
the green led is turned on. If this condi-
tion is not restored in more than one
minute, the boiler will stop, the display
will still show anomaly AL 07 and the red
102
led will turn on.
Press the key
up the boiler again.
– PARASITE FLAME ANOMALY "AL 08"
If the flame control section recognises
the presence of flames also in phases
when they should not be present, it
means there is a breakdown in the flame
detection circuit; the boiler will stop and
the display will show anomaly "AL 08".
– AUXILIARY SENSOR
ANOMALY "AL 10"
ONLY FOR BOILER WITH SOLAR PLANT
COUPLING (PAR 2 = 2):
Fig. 22/b
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.
– SMOKE SENSOR
INTERVENTION (fig. 22/d)
If the smoke sensor intervenes, the boi-
ler will stop and the display will show ano-
maly AL 13.
Press the key
up the boiler again.

– SMOKE SENSOR ANOMALY "AL 14"
When the fumes probe is opened or

short-circuited, the boiler stops and the
displays shows anomaly AL 14.
– FAN ANOMALY "AL 15"
Fan revolutions are not within the pre-
established speed range. If the anomaly
activation condition lasts for over two
minutes, the boiler will forcedly stop for
thirty minutes and the display will show
anomaly AL 15. After this forced time,
the boiler will start working again.
– CONDENSATE LEVEL
ANOMALY "AL 18"
Activation is determined by the closing of
the condensate level sensor normally
open contact. The boiler will forcedly
stop for ten minutes and the display will
show anomaly AL 18. After this forced
time, the boiler will start working again.
