1.7 New-generation simplified electronic controller
1.7.3 Lighting in pellet mode, electronic controller
The simplified electronic controller automatically manages the
entire lighting process, according to the following stages:
1.
BURN POT CLEANING
for 2 minutes (the display shows
HOP.1)
2.
PELLET LOADING
up to 2 cm from the rim of the burn pot;
duration approx. 4 minutes (the display shows PELL.1)
3.
ACTIVATION OF ELECTRICAL ELEMENT AND FAN:
combustion starts; duration approx. 4 minutes (the display
shows IGNIT.1)
4.
COMBUSTION STABILISATION:
the flame gradually
spreads to the pellets in the burn pot; duration approx. 10
minutes (the display shows STAB.1)
5.
SWITCH TO OPERATION AT PREVIOUSLY SET POWER
LEVEL
: the fireplace has completed the lighting stage and
automatically goes to the power level set before the last
shutdown, which is shown on the display (for example,
PWR>MEDIUM).
If the stove still fails to light, carry out the operations described in
chap. “troubleshooting”
.
Approximately every 30 minutes an automatic cleaning
cycle of 2 minutes is carried out, with pellet feed at
minimum and combustion air at maximum (the display
shows the message HOP. 3 and the corresponding LED
lights up).
The burner is managed with the room temperature probe: on
reaching the set room temperature, it switches to the economy
mode (the display shows the message ECON.) and restarts
when the room temperature falls.
The fan delivering hot air in the room switches on when the air in
the boiler exceeds 40 °C. Fan speed increases gradually as the
boiler temperature increases or, manually, by programming it on
the electronic controller.
If, after a couple hours’ operation, the glass starts to go black,
or the pellets fall out or the stove shuts down, this means that
the pellets used are not of the recommended type (for pellet
characteristics, see
chap. 1.16
), or that the combustion air in
insufficient (make sure the combustion fan is not dirty).
Therefore a few operations are necessary to eliminate the
problem (see
par. 1.7.10
).
PWR > HOP. 1
initial cleaning (first lighting)
PWR > PELL. 1
automatic loading of pellets in burn pot for ignition (first lighting)
PWR > IGNIT. 1
stage when the electrical element heats up to ignite the pellets (first lighting)
PWR > STAB. 1
pellet ignition and flame stabilisation stage, wait 10 minutes (first ignition)
PWR > MIN
minimum power
PWR > MED
medium power
PWR > MAX
maximum power
PWR > ECON.
economy stage
PWR > HOP. 3
burn pot cleaning stage
MESSAGES APPEARING ON THE DISPLAY DURING OPERATION
IMPORTANT!
Remember that the combustion fan pipe must not be
longer than 50 cm (see chap. 2.2).
