Electronic pellet burner controller – NPBC-V3C-2 / NPBC-V4C-2
Flame Detection – Set the temperature difference for successful ignition and extinction and the
maximum time for the extinguishing procedure.
The ignition is successful, if the
current temperature of the exhaust
gases is 20°C higher than it was in
the beginning of the procedure
The extinction is successful, if the
current temperature of the exhause
gases is 40°C lower than it was in
the beginning of the procedure
Power Modulation – Set the difference between the set temperature and the boiler's temperature
for each power level. When it is more than the value for P3, the burner works on 3rd power level.
When it is more than the value for P2, but less than the value for P3, the burner works on 2nd
power level. When the difference is between the values for P1 and P2, the burner works on 1st
power level. When it's less than the value for P1, the burner woks on Suspend power level. While
on Suspend, if the difference between the set temperature and the boiler's temperature increases
enough for 1st power level, the burner automatically switches to it. If the difference doesn't
increase, the burner works on Suspend power level for as long as it is set in the parameter Duration
[min]. While on Suspend, if the temperature of the boiler is still increasing, when it gets higher than
the set temperature with as many degrees as set in the parameter Overheating, the burner will turn
off immediately.
If there is no change in
the conditions,the burner
works on Suspend power
Level for 20 minutes
and then turns off
If the boiler's temperature
gets higher than the set temp
With 8°C, the burner
turns off immediately.

During the extinguishing procedure,
the controller will wait for 5 min.
for the temperature to drop with
40°C. After this time the burner
will be considered to be off
If the difference between the
set temperature and the current
Temperature of the boiler is more
than 10°C, the burner works on P3
If the difference is between 5°C
and 10°C, the burner works on P2
If difference is between 0°C
and 5°C, the burner works on P2
Otherwise, it will work on
Suspend power level
