8.4 ERROR 4 NOT ACTIVE
8.5 ERROR 5 NO PELLETS
If during operation the combustion chamber temperature drops below the set limit. The cycle ends with a system error. This
may be due to a lack of fuel or the blocked distribution of the fuel.
8.6 ERROR 6 PRESSURE SWITCH / THERMOSTAT ALARM
If the pressure gauge is activated due to insufficient vacuum of the flue gas extraction, the cycle stops heating with error 6.
This may be caused by the obstruction of flue gas extraction or expulsion. If the tank temperature increases by 57/63°C, the
stove turns off and error 6 appears on the display.
Once the temperature has dropped below the minimum limit, consent for operation is once more activated, but as a precauti-
onary measure, prior to each ignition following an error, always check the causes and then restore them.
8.7 ERROR 7 NOT ACTIVE
8.8 ERROR 8 NO MAINS POWER
If during any stage of stove operation there is a mains power failure, when the power returns, a no mains power alarm is
notified and the stove shuts down.
8.9 ERROR 9 FLUE GAS MOTOR ALARM
During the heating stage the flue gas motor is monitored, if its speed falls below a minimum level, the stove goes into error
mode due to the malfunction of the flue gas extraction motor and switches directly into cooling mode at
maximum speed. This problem may also be due to ash deposited in the flue gas pass and due to insufficient routine mainte-
nance.
8.10 ERROR 10 OVERTEMPERATURE ALARM
This function is enabled through the system parameter 61. The temperature of the printed circuit boards is monitored, and if
it exceeds 70 for more than 3 minutes the stove switches into cooling mode due to overtemperature.
8.11 ERROR 11 EXPIRY PASSED
If a stove expiry date has been set, this status is displayed when the stove is turned on. To restore its operation, the relative
parameters must be accessed and updated.
8.12 ERROR 12 FLUE GAS PROBE
9. PRELIMINARY OPERATIONS
9.1 PELLET LOADING
The first operation to be carried out before turning the appliance on is to
fill the tank with fuel (pellets), preferably using a scoop.
!
Be careful not to touch the hot parts if fuel refilling is carried out with
the stove running.
Do not empty the bag directly into the tank to avoid loading sawdust or
other foreign elements that could compromise correct functioning of the
stove and to avoid dispersing the pellets outside the tank itself.
F
Be sure to close the lid of the tank well after loading the pellets. The
safety pressure switch (for models with outside air intake) verifies pro-
per closure (Fig. 24) and sends an alarm if the lid is left open for more
than 20 seconds with the stove running.
ATTENTION:
9.2 ELECTRICAL POWER SUPPLY
Connect the stove to the mains power, operate the ON switch on the back of the stove, positioning it to "I"
(Fig. 25). If the connection is properly made, the display will light up.
!
During long periods of non-use, it is recommended to position the switch on the back of the machine to
OFF (O).
F 
D o not touch the control panel when the stove is being powered.
Do not insert fuel through the aeration outlets.
