– PARASITE FLAME ANOMALY ALARM
08 (fig. 23/g)
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/h)
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
ALARM 10 (fig. 23/l)
BOILER WITH ACCUMULATION: anomaly
of the D.H.W. sensor (SB). When the
106
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 for boilers which fore-
see 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. When the sensor is open or
short circuited, the boiler loses the sun-
panel function and the display will show
anomaly "ALL 10".

– ACTIVATION OF THE "ALL 13" EXHAU-
ST FUMES PROBE (fig. 23/p)
The activation of this probe causes the
boiler to stop and error message "ALL
13" to display.
Press the key
start up the boiler again.

short-circuited, the boiler stops and
error message "ALL 14" displays.
– "ALL 15" FAN ERROR (fg. 23/r)
The fan speed does not fall within the
rated speed range. If the error condi-
tions persists for two minutes, the boiler
activates a forced stop for thirty minu-
tes. A new start attempt is repeated
after the expiry of this interval of time.
– SAFETY THERMOSTAT INTERVENTION
FIRST MIXED ZONE "ALL 20" (fig.

When it results that the ZONA MIX
board is connected to the boiler the
safety thermostat intervention switches

valve closes and on the display the ano-

boiler continues to function normally.

MALY FIRST MIXED ZONE "ALL 21"
(fig. 23/q)
When it results that the ZONA MIX
board is connected to the boiler and the
delivery probe is open or short circuited
on the display the anomaly ALL 21
appears. During this anomaly, the boiler
continues to function normally.
