TYPE OF PROBLEM SOLUTION
A03
Pellet tank temperature exceeds foreseen
safety limit.
Overheating of the stove body
The structure is too hot because the product has been
operating for too long at maximum power, or it is
poorly ventilated, or the air fans are faulty. When the
stove is sufficiently cold, press button B of the control
panel or OFF on the remote control to cancel the alarm
A03. Once the alarm is cancelled it is possible to relight
the stove normally.
A04 The temperature of the smoke discharge has
exceeded pre-set safety limits
The stove will shut off automatically. Let the stove cool
off for a few minutes, then re-light it.
Check smoke release and the type of pellet being used.
A06 The smoke extractor is not able to provide the
primary air required for combustion.
Draught difficulties or clogging of grate.
Check whether the grate is clogged by incrustation and
clean as required.
Control and if necessary clean the smoke duct and the
air intake.
A07
During the function of the stove, an
uncontrolled air intake occurred in the
combustion chamber or an obstruction in the
flue pipe.
Caused by prolonged opening of the fire door or by
substantial air infiltration (e.g. smoke fan inspection
plug missing) If not caused by these factors control and
if necessary clean the smoke duct and the flue pipe.
A08
Flue-gas exhaust fan broken
Check that the smoke fan compartment is clean and if it
is dirt that is blocking it.
If insufficient, the smoke fan is defective. Call an
authorized service centre to make the replacement.
A09
The smoke probe is defective and does not
properly measure the temperature of the
discharge smoke
Contact an authorized service centre to replace the
component.
A10
The plug is defective
Contact an authorized service centre to replace the
component.
A11
Defective pellet feeder Contact an authorized service centre to replace the
component.
A12
The remote control has been beyond the
reception range of the stove for more than
three hours, or its batteries are dead.
NOTE: only in this case the stove does not go
into alarm shutdown, but continues operating
in the mode that the remote control set via the
last sent command.
Move the remote control back to within range of the
stove, or change the batteries if they are dead.
As soon as the stove receives a new signal from the
stove, the alarm indications will disappear. A easy way
to force a transmission to the stove is to press button 4.
This changes operating mode from manual to automatic
and vice versa.
A13
Generic failure of electronic control unit
Contact an authorized service centre to replace the
component.
A14

This alarm is not blocked, only a warning screen
appears. Contact an authorized service centre to
replace the component.
SEr
Periodic maintenance warning

maintenance intervention is necessary. Contact a
specialist MCZ technician.
