Electronic pellet burner controller – NPBC-V3C-1/ NPBC-V4C-1
NPBC-V3C-1 is a new updated version of the popular controller NPBC-V3M-1. It works with a
new Control module with a color TFT display NRC-6 and NPBC-V3M Executive module.
NPBC-V4C-1 controller has the same functionality and a new improved executive module -
This models' most important advantages are:
Clearer and intuitive user interface with modern looking menus and 6 control buttons.
Additional warning messages about incorrect parameter input or if parameters from a different
menu require corrections after the current changes.
The Control module can be equipped with a WiFi module NRM-W3 for connection with the
Naturela remote monitoring and control system through the web
4 preset fuel profiles make switching between different fuels easier than ever
Statistical information about the fuel consumption divided by hour and based on a calibrating
constant parameter for the fuel auger's capacity.

The controller NPBC-V3C-1 / NPBC-V4C-1 are designed to run burners, which use a photo
sensor to detect 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-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!
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 !
