Electronic pellet burner controller - NPBC-V3M
I
NTRODUCTION
The controller NPBC-V3M-1 is designed to run burners, which use a photo sensor to detect the
burning fire. It measures the level of illumination from the burning fire. The pulsing control of the
auger motor from the pellet tank allows the precise dosing of the amount of pellets that goes to the
burner. NPBC-V3M-1 is able to control an optional internal auger motor that forwards the pellets
inside the burner. The controller runs two blowers: one that provides the air to the burning chamber
and the other one is an additional fan, for example, for taking out the exhaust gases from the boiler, if
necessary. Both blowers' power can be adjusted from the controller. NPBC-V3M-1 has an option to
control the temperature of the exhaust gases by a high temperature sensor pt100, mounted in the
entrance of the vent. An additional powerful blower could also be connected to the controller to blow
away the ashes from the burning chamber during the cleaning procedures. The controller runs up to
two circulation pumps: for the heating installation and for the hot water heater installation. All of the
controlled mechanisms must work on 220VAC or 110VAC mains power supply!
