Controller for pellet oven – NPBC-V3C-B
Ignition
– This menu contains all of the required parameters to set the ignition. If the first ignition
attempt fails, the burner can do few more. Set their number from this menu (
Ignition retries
), as well
as the time for the main auger to load the first dose of pellets for the ignition (
Loading [Sec]
). The
parameter Exhaust fan sets the exhaust fan's speed during this stage. The ignition cycle is divided on 3
stages:
Stage 1 – only the ignition heater works
Stage 2 – the main fan works on lower speed along with the ignition heater
Stage 3 – the main fan works on higher speed along with the ignition heater
If the photo sensor detects a successful ignition the procedure will be terminated and the burner
proceeds to unfolding the fire.
Unfolding
– Right after the ignition the burner doesn't switch immediately to full power, because this
might extinguish the unsteady fire. This menu sets the process of unfolding the fire on two stages:
burning of the first fuel dose and smooth unfolding. The upper field sets the fans' speed while the first
fuel dose is burning and the duration of this stage in seconds. The main auger does not load new pellets
while the first dose is burning. The bottom field sets for how long the burner should work on P1 and
P2 power levels before switching to the required power level according to the boiler's temperature.
