– D.H.W. SENSOR ANOMALY ALARM 04
(fig. 23/3)
If the D.H.W. sensor (SS) is open or
short circuited, the boiler will function
but will not modulate the power for
D.H.W. The display will show the alarm
ALL 04.

– C.H. FLOW SENSOR ANOMALY
ALARM 05 (fig. 23/4)
If the C.H. flow sensor (SM) is open or
short circuited, the boiler will not func-
tion and the display will show the alarm
ALL 05.

– FLAME BLOCK ALARM 06 (fig. 23/5)
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 ALL 06.
Press the key of the controls (2) to
start up the boiler again.

– SAFETY THERMOSTAT OR LIMIT THER-
MOSTAT ANOMALY ALARM 07 (fig.
23/6
If the connection with the safety thermo-
stat/limit thermostat is interrupted, the
boiler will stop; the flame control will
remain waiting to be switched off for one
minute, keeping the system pump on for
that period.
If, the thermostat connection is restored
within the minute, the boiler will start up
working normally again, otherwise it will
stop and the display will show the alarm
ALL 07.
Press the key of the controls (2) to
start up the boiler again.

– PARASITE FLAME ANOMALY ALARM
08 (fig. 23/7)
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 ALL 08.

– WATER CIRCUL ATION ANOMALY
ALARM 09 (fig. 23/8)
There is no water circulation in the pri-
mary circuit. If the anomaly occurs upon
first request, the boiler performs a maxi-
mum of three attempts to assure the
presence of water inside the primary cir-
cuit; it then stops showing on the display
the ALL 09 anomaly. If the anomaly
occurs during normal functioning, the
display immediately shows the ALL 09
anomaly, keeping the plant pump and the
eventual boiler pump, switched on for 1
minute.
In this case there was a sudden increase
of the boiler inner temperature. Check to
see if there is water circulation inside
the boiler and check if the pump is ope-
rating properly.
To exit the anomaly press the
ton of the controls (2). If the anomaly
persists, request assistance from quali-
fied technical personnel.

– AUXILIARY SENSOR ANOMALY
ALARM 10 (fig. 23/9)
BOILER WITH ACCUMULATION: anomaly
of the D.H.W. sensor (SB). When the
D.H.W. sensor is open or short circuited,
the display will show anomaly ALL 10.
The boiler will function but will not modu-
late power for the D.H.W.
BOILER ONLY FOR HEATING: antifreeze
sensor anomaly (SA) for boilers which
foresee the use of antifreeze sensors.
When the sensor is open or short circui-
ted, the boiler loses part of its anti-freeze
functions and the display will show ano-
maly ALL 10.
BOILER COMBINED WITH SUN-PANEL
SYSTEM: anomaly of the D.H.W. input
sensor (ST). When the sensor is open or
short circuited, the boiler loses the sun-
panel function and the display will show
anomaly ALL 10.
