Main solutions
AL09
H2OPROBE
FAILURE
• Water probe broken or incorrectly wired.
• Make sure the two probe wires are correctly
inserted in the terminal. There are no mandatory
connection directions for IN2 terminals
• Replace the water probe.
AL10
STOVEH2O
OVERHEAT
• Water temperature in the stove exceeded 85°C.
• Make sure the pump outlet to the system heating
circuit is open in the event of dissipation, that there
are not passageway obstructions due to zone
solenoid valve triggered by external components.
• Make sure that the pump and device are working
properly.
• Make sure that the system and device air venting
has been completed.
• Make sure any device isolating valves are open.
AL11
H2O MAX
PRESSURE
• Water pressure reached maximum 2.7 bar value. • Check circuit pressure adjusting cold system
pressure to 1.0 bar.
• In some cases, an expansion tank may be required
for the large amount of water in the system.
• Make sure the safety valve is connected to the
drain.
• Make sure air was correctly released from the
heating system.
• Check the pressure probe connection, it may have
disconnected.
AL12
LOW AIR
DRAFT
• If a flow sensor is installed on the model, it
indicates that comburent air flow is not sufficient
for combustion.
• Make sure the comburent air intake tube is not
obstructed or dirty.
• Check that the sensor is perfectly clean.
• Check that the fume deflector inside the
combustion chamber is perfectly clean.
• Check that all the firebox air flow holes are
perfectly clean.
• Check that the fume inspection cap is firmly closed.
• Make sure the door is closed.
AL13
NON-STOP
PEL LOAD
• Pellet load is continuous and thus incorrect.
• Make sure load start parameters are correct.
• Make sure the board has not overheated. Contact
the CAT.
AL14
ANORMAL
FLAME
• Fume temperature during flame stabilisation does
not correctly increase.
• Make sure functional settings are correct.
• Check for any auger jams or clogs.
AL15
M-BOARD
SECURITY
• Electronic board temperature has exceeded the
safety threshold.
• Make sure room aeration is correct.
• Check appliance operating settings, they could
generate excessive overheating in the machine
body.
• Check the aeration grid on the back of the device,
it may be dirty and not allow enough cooling air
to flow.
AL16
SAFETY
SENSOR
• If the temperature sensor is installed on the model,
it signals that the temperature in the appliance
cladding has exceeded the maximum admitted
value.
• Make sure room aeration is correct.
• Check appliance operating settings, they could
generate excessive overheating in the machine
body.
• Check the aeration grid on the back of the device,
it may be dirty and not allow enough cooling air
to flow.
AL17
HI-PROBE
BUFFER
• The Puffer Hi probe is disconnected or broken.
• Check probe wiring. If correct, replace the probe.
AL18
DHW HI
FAILURE
• The boiler probe is disconnected or broken.
• Check probe wiring. If correct, replace the probe.
AL19
THERMIC
WATER
• Stove water manual reset safety thermostat
triggered.
• Make sure functional settings are correct.
• Make sure hydraulic connections are correct and
that there are no intercepts between the boiler and
system.
