Electronic pellet burner controller – NPBC-V3C-1/ NPBC-V4C-1/ NPBC-V4E-1
tank allows the precise dosing of the amount of pellets that goes to the burner.
NPBC-V3C-1/ NPBC-
V4C-1
can control an optional internal auger motor that forwards the pellets inside the burner. The
controller runs two fans: one that provides the air to the burning chamber and the other is an additional
fan, for example, for taking out the exhaust gases from the boiler, if necessary. Both fans' power can be
adjusted from the controller. The controllers have an option to measure and control the temperature of
the exhaust gases with a high temperature sensor pt100, mounted in the entrance of the vent. For more
effective cleaning process the controllers can also run an additional powerful fan to blow away the
ashes from the burning chamber or a mechanical cleaning mechanism with an option to be run by one
controlling or powering up voltage. The controllers 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!
Important:
NPBC-V4C controller must be powered at least 3 minutes for normal operation of the clock support
system and burning process tracking when the power supply is switched off !
