POSSIBLE TROUBLESHOOTING
In the event of problems the stove stops automatically and runs the shutdown process and the display shows text
regarding the motivation of the shutdown (see the various alarms below).
Never pull the plug during shutdown on account of malfunction.
Should it block, to restart the stove you will need to allow the turn-off procedure to take place (600 seconds with
audible signal), and then press the button
Do not turn the stove on again before checking the cause of the malfunction and CLEANING/ EMPTYING the crucible.
INDICATION OF POSSIBLE CAUSES OF MALFUNCTION AND INDICATIONS AND REMEDIES:
1) Signalling: Verific./air flow: (intervenes if the flow sensor detects insufficient combustion ).
Problem:
Turns off for lack of depression
Air flow may be insufficient because the door is open, the door does not close properly (e.g. bad seal), there is an
air intake or smoke extraction problem, or the combustion chamber is clogged.
Actions:
Check:
• door closure;
• combustion air intake duct (clean, paying attention to the flow sensor components);
• clean the flow sensor with dry air (like that used for PC keyboards);
• stove location: respect and check a minimum distance of 10 cm from the wall;
• combustion chamber position and cleanliness (clean regularly according to the type of pellet);
• smoke duct (clean);
• installation (if it does not comply with regulations or the smoke outlet has more than 3 bends);
If you suspect the sensor is malfunctioning, carry out cold tests. If the conditions are changed (for example by
opening the door) and the value does not change, there is a sensor problem (DEALER).
N.B.:
The no depression alarm may also occur during ignition, since the flow sensor starts monitoring 90 seconds after
the ignition cycle begins.
2) Segnalazione: Signalling: Verific./extract.: (this trips if the smoke extraction speed sensor detects a fault)
Problem:
Shutdown for smoke extraction speed fault detection
Actions:
• Check smoke extractor function (devolution sensor connection) and board (DEALER).
• Check smoke channel for dirt
• Verify the electrical system and earthing system.
• Check eletronic circuit board (DEALER).
3) Signalling:
Stop/Flame: (this trips if the thermocouple detects a smoke temperature lower than the value set, which it
interprets as the absence of flames)
Problem:
Turns off due to drop in smoke temperature
Actions:
• lack of pellets
• too many pellets have suffocated the flame, check pellet quality (DEALER)
• the maximum thermostat has intervened (rare, this only intervenes in the event of excessive smoke
temperature) (DEALER)
• Check correct functioning of the pressure switch (CAT)
4) Signalling:
Block_FI/NO Start: (intervenes if a flame fails to appear within a maximum of 15 minutes, or if ignition
temperature is not reached).
• Check correct functioning of the pressure switch (CAT)
Problem:
Turns off due to incorrect smoke temperature during ignition
Distinguish either of the following cases:
Flame does NOT appear
Actions:
• Check: - combustion chamber position and cleanliness;
• Check that there are pellets in the tank and the fire box
• arrival of combustion air in the combustion chamber;
• if the heating element is working (DEALER);
• room temperature (if lower than 3°C use a firelighter) and damp.
Try to light with a firelighter (see page 34).
Flames appear, but AF appears on the display after Ar
Actions:
• Check: (only by the Dealer)
• if the thermocouple is working (DEALER);
• start-up temperature setting in the parameters (DEALER).
• Repeat start up after having emptying the brazier.
5) Signalling:
Black Out: (not a defect of the stove).
Problem:
Turns off due to lack of electricity
Actions:
• Check electricity connection and drops in voltage.
6) Signalling:
Fault/RC: (intervenes if the thermo coupling has failed or is disconnected).
Problem:
Turns off due to thermo coupling failed or disconnected
Actions:
• Check connection of thermo coupling to board: check function in cold test (DEALER).
