Display Reason Solution
START The start phase is in progress -
PELLET FEEDING
the continuous feeding of the pellets during the ignition
phase is in progress
-
IGNITION The boiler is in ignition phase -
STARTUP the work preparation phase is in progress -
WORK
the normal working phase is in progress, the boiler is
working at the power set
-
BURN POT CLEANING the automatic burn pot cleaning is in progress -
FINAL CLEANING the nal cleaning is in progress -
MODULATION the boiler is working at minimum power -
STANDBY
boiler waiting for re-ignition due to an external
thermostat
the boiler will only re-start when the external thermostats makes a request
COOL. STDBYBLACK OUT the boiler is cooling after a power cut. once cooling is completed it will automatically ignite
HOFF
boiler in stand-by for re-ignition because the
temperature of the water has exceeded the parameters
set
as soon as the water temperature drops below the pre-established
parameters, the boiler will switch back on
ANTIFREEZE
the anti-freeze function is in progress as the H2O t° is
below the factory set threshold
the pump is active until the water reaches the pre-set factory parameter
ANTILOCK
If the boiler has remained in the O status for at least 96
hours, the pump starts to function, so that blocking does
not occur.
the pump activates for a brief period, in a way to prevent blockage of the
same.

FUMES FAILURE Flue gas motor fault contact after-sales centre
FUMES PROBE Fumes probe failure. contact after-sales centre
HOT FUMES High ue gas temperature
check the calibration of pellet regulation. If this cannot be solved, contact an
authorised technician
NO FLOW ALARM
The door is not closed correctly.
The ash drawer is not closed correctly.
The combustion chamber is dirty.
The ue exhaust or air supply pipe is blocked.
Check hermetic door closure.
Check hermetic closure of the ash drawer.
Check cleanliness of the fumes pipe and the combustion chamber.
Check cleanliness if the air supply pipe and the ow sensor
NO IGNITION
The pellet feed-box is empty.
Pellet feed calibration inadequate.
Check for the presence of pellets in the feed-box.
Regulate the pellet ow
Check the procedures described in the “Ignition” chapter.
BLACKOUT NO IGN. No current during the ignition phase.
Take the boiler to OFF conditions using key 1 and repeat the procedure
described in the "Ignition" chapter.
NO PELLETS
The pellet feed-box is empty.
No pellet feed.
The motor reducer does not feed pellets.
Check for the presence of pellets in the feed-box.
Adjust pellet ow (see “Pellet feed adjustment”).
DEPR ALARM
The door is not closed correctly.
The ash drawer is not closed correctly.
The combustion chamber is dirty.
The ue exhaust pipe is blocked
Check hermetic door closure.
Check hermetic closure of the ash drawer.
Check cleanliness of the fumes pipe and the combustion chamber.
Check the mechanical pressure switch (air side)
DEPR SENSOR
DAMAGE
ow sensor faulty
sensor disconnected
contact after-sales centre
H2O OVERTEMP
the water in the boiler has exceeded 95°C.
Possible air in the system.
Insucient circulation.
No or inadequate safety zone.
Possible pump anomaly.
contact after-sales centre
MINIMUM
PRESSURE ALARM
the system pressure read by the pressure switch is too low.
Possible presence of air in the system.
Possible lack of water or leaks due to anomalies in some
system component.
contact after-sales centre
TRAPDOOR BLOCK The automatic cleaning of the burn pot results blocked.
Switch o the machine, wait for complete cooling and repeat the ignition
cycle.
If the problem persists, the reset operations must be carried out by an
authorised technician.
