Electronic pellet burner controller – NPBC-V3C-K / NPBC-V4C-K / NPBC-V4E-K
NPBC-V3C is a new updated version of the popular controller NPBC-V3M. It works with a new
Control module with a color TFT display NRC-6 and NPBC-V3M Executive module.
NPBC-V4C controller has the same functionality and a new improved executive module - NPBC-
V4 or NPBC-V4E.
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.
A list with short description, date and time of the occurred errors and any other event
•
concerning the controller's work.
More parameters about the burner's work and current state displayed on the main screen at
•
the same time.
A micro USB coupling on the face panel of the Control module for connection with a
•
computer with software for direct control and monitoring.

Controllers NPBC-V3C-K / NPBC-V4C-K / NPBC-V4E-K are designed to run burners that detect
the burning fire by measuring the temperature of the exhaust gases with a pt100 high temperature
sensor installed at the beginning of the vent. 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-K /
NPBC-V4C-K / NPBC-V4E-K can 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 is an additional fan, for example, for taking out the exhaust gases, if
necessary. Both blowers' power can be adjusted from the controller. For more effective cleaning
process the controller 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 controller runs a convection fan. Fan's switching on/ off depend on the
exhaust gases temperature.
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 !
