NO NEG
PRESS
-In the work stage the boiler
detects a pressure below the
vacuum switch setting threshold.
-The system is stopped.
-The combustion chamber is dirty.
-The fume duct is obstructed.
-The fire door is not closed.
-The overpressure valves are
open-stuck.
-Faulty vacuum switch.
-Check cleanness of the fume
duct and combustion chamber.
-Check hermetic closing of the
door.
-Check closing of the
overpressure valves.
-Other reinstatement operations
must be carried out by a service
centre.
AL 9
INSUFF
DRAUGHT
-Appears when the combustion
air flow is below a certain
threshold.
-The combustion chamber is dirty.
-The fume duct is obstructed.
-The fire door is not closed.
-The overpressure valves are
open-stuck.
-Faulty air flow meter.
-Check cleanness of the fume
duct and combustion chamber.
-Check hermetic closing of the
door.
-Check
closing of the
overpressure valves.
-Other reinstatement operations
must be carried out by a service
centre.
AL E
WATER
PRESSURE
-Occurs when the water pressure
does not come within the values
for correct operation.
-The system is stopped.
-Occurs when the pressure
transducer on the water circuit
detects a pressure below or
above the fixed limits. -Check the cause of the problem,
restoring the circuit pressure by
bringing it to the normal operating
value.
AL A
SAFETY
H
2
O
-Occurs in case of cutting in
heating chamber water
temperature safety thermostat.
-The system is stopped.
-The safety thermostat has
detected a temperature above
the setting threshold due to
overheating
of the heating
chamber water blocking
gearmotor operation.
-Check the cause of excessive
overheating.
-Reset the relevant safety
thermostat by pressing the reset
button.
AL b
AUG TRIAC
ERROR
-Occurs when the gearmotor
works continuously and for more
than 60 sec.
-The system is stopped.
-The controller detects a faulty
gearmotor control relay (contacts
stuck).
-Reinstatement operations must
be carried out by a service centre.
Al c
WATER
PROBE
-Occurs in case of water T
detection probe
fault,
displaying T H2O = 0 °C.
- The shutdown procedure
is activated.
-Faulty probe
-The probe is disconnected from
the board.
-Reinstatement operations must
be carried out by a service centre.
AL d
HOT
WATER
-Occurs when the water
temperature has exceeded the
fixed limits.
-The system is stopped.
-Occurs when the temperature
probe in the heating chamber
detects a value above 92°C.
-Check the cause of the problem,
restoring the temperature by
bringing it to the normal operating
value.
AWAITING
COOL
-Occurs on relighting the boiler
immediately after having shut it
down.
-Reset attempt in shutdown stage
with boiler hot in cooling stage. -Alarm reset is possible only after
shutdown.
AIRFLOW
METER
FAILURE
-Occurs when the air flow meter is
disconnected.
-The controller does not detect
the amount of combustion air
and does not shut down the
boiler; it only excludes the air
flow meter functions. -Reinstatement operations must
be carried out by a service
centre.
FROST RISK
-Occurs when the water
temperature falls below a certain
value.
-The boiler controller detects the
water temperature below 6°C
and displays a message.
-The pump starts in order to move
the water inside the heating
circuit.
- Monitor the water temperature
so that it does not fall below 0°C.
SERVICE
DUE
-Occurs when the boiler has
exceeded 1800 hours of
operation since the previous
servicing.
-Extraordinary maintenance
notice.
- Cleaning - extraordinary
maintenance and reinstatement
operations must be carried out by
an authorised service centre.
