– SAFETY/LIMIT THERMOSTAT ANO-
MALY 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
operating properly.
To exit the anomaly press the
ton of the controls (2). If the anomaly
reoccurs, request assistance from quali-
fied technical personnel.
– AUXILIARY SENSOR
ALARM 10 (fig. 23/9)
When the antifreeze siphon sensor (SA)
or D.H.W. sensor L.2000 (SB) is open or
short circuited, the display will show ano-
maly ALL 10.
– ACTIVATION OF THE "ALL 13" EXHAU-
ST FUMES PROBE (fig. 23/10)
The activation of this probe causes the
boiler to stop and error message ALL 13
to display.
Press the key of the controls (2) to
start up the boiler again.
– "ALL 14" EXHAUST FUMES PROBE
ERROR (fig. 23/11)
If the exhaust fumes probes is open or
short-circuited, the boiler stops and
error message ALL 14 displays.
