Output power levels 4.5
Burner has 6 preset output power levels. For every level, program calculates correct fuel amount what
depends on fuel’s calorific value and burner’s internal feeder productivity. The feeder productivity for
normal, light and heavy pellets can be changed from main menu. For normal pellets it is 33 gramms per
rotation. Calculated amount of fuel is divided into periodic feeding cycles. In every cycle internal feeder
makes half rotation. If the calculated cycle comes too short then the cycle length is doubled and fuel is
fed with by full rotation of feeder. For every power level there is different preset fan rotation speed.
Burner selects the output level between preset min and max powers. When burning time has been more
than 30 min (PAR 15), next time burner takes one level up, when burning time has been less than 15 min
(PAR 16), next time burner takes one power level down.
