to burn properly, an appropriate amount
of air must be supplied. Therefore, the
speeds of the main fan (row

be set.

This parameter is not corrected!
We recommend that you set the P3
power to the maximum power you will
want to receive from the burner. Power
P2 should be 50% of P3 and P1 should
be 20% of P3. With such a setting, the
controller will be able to smoothly mod
-
ulate the burner power in the range of
20 to 100%, changing the power if nec
-
essary for each new cycle. For example,
if you need 75% power, the controller
will switch from power P3 to P2 and then
back to P3 at regular intervals. Thus, the
average power can be reduced to the fol
-
lowing (100 + 50) / 2 = 75. The switch
-
ing time will depend on the inertia of
the whole system and the set tempera
-
ture differences in the menu
"Service
settings" -> "Power modulation"
. The
smallest interval for switching between
two powers can be one cycle, which is
about 20-30 seconds. For such a short
switching period, the temperature of the
heating system will not change signifi
-
cantly to feel the pulsation of power. By
adding
"Maintenance"
power, which will
be less than P1, the burner gets an even
wider range of modulation.
It is important when adjusting
the
maintenance
power
parameters, not to allow such
an increase in the cycle between
two pellet feeds that the
available pellets in the upper
chamber burn and do not leave
enough heat to ignite the next
pellets!
Intermediate Cleaning -
This menu sets
an additional feature that the NPBC-V3C
controller allows, called "Intermediate
Cleaning". The idea is that while the
burner is operating normally, only in
-
crease the speed of the fans, which will
temporarily raise the temperature of the
fire and this will lead to a more complete
combustion of slag and ash. A mechani
-
cal cleaning mechanism connected to
the FC outlet can also be used, which can
be activated periodically while the fire
is burning to scrape off the stuck slag or
ash.
T
o do this, you need to check the
"Exit FC"
line and perhaps remove the
"Change vent"
line.
