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
function 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 re-
ason 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
LI-
MIT THERMOSTAT ANOMALY ALARM
07 (fig. 23/6
If the connection with the safety ther-
mostat/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 resto-
red within the minute, the boiler will
start up working normally again, other-
wise 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 me-
ans there is a breakdown in the flame
detection circuit; the boiler will stop
and the display will show anomaly ALL
08.

WATER
CIRCULATION
ANOMALY
ALARM 09 (fig. 23/8)
There is no water circulation in the
primary circuit. If the anomaly occurs
upon first request, the boiler performs
a maximum of three attempts to assure
the presence of water inside the prima-
ry circuit; it then stops showing on the
display the ALL 09 anomaly. If the ano-
maly 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 operating properly.
To exit the anomaly press the
button of the controls (2). If the anomaly
persists, request assistance from qua-
lified technical personnel.

AUXILIARY SENSOR ANOMALY ALARM
10 (fig. 23/9)
BOILER WITH ACCUMULATION: ano-
maly of the D.H.W. sensor (SB). When
the D.H.W. sensor is open or short cir-
cuited, the display will show anomaly
ALL 10. The boiler will function but will
not modulate power for the D.H.W.
BOILER ONLY FOR HEATING: antifre-
eze sensor anomaly (SA) for boilers
which foresee the use of antifreeze
sensors.
When the sensor is open or short circu-
ited, the boiler loses part of its anti-fre-
eze functions and the display will show
anomaly 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.
