Electronic pellet burner controller – NPBC-V3C-1/ NPBC-V4C-1/ NPBC-V4E-1
Common Factory Settings for all types of fuel:
Equipment
– Enable/disable the additional mechanisms and sensors of the burner's configuration and
set the polarity of the room thermostat's and the OD input's contacts:
General Settings
– Set the internal auger motor's active time (Burner Feeder), the maximum allowed
set temperature for the boiler, the main auger's capacity and pending time for FC output, if necessary.
The internal auger motor always starts at the same time with the main auger and works for as long as it
is set in this menu. Its active time in seconds is:

where: T

is the internal auger motor's active time;
T
fa
is the fuel auger's active time (main auger).
Instead of powerful cleaning fan, the FC output can control a mechanical cleaning actuator. During the
cleaning procedures where the FC output is active, the actuator moves in one direction to push out the
ashes. After the procedure is over the controller cuts the power supply to the FC output and the
actuator needs time to get back to its initial position. Put a check sign on the parameter FC output and

Put a check sign if the burner
works with an internal auger motor
Put check signs if the CH installation
has a room thermostat and its
contact is normally opened (NO)
Put a check sign if the burner
works with a high temperature
sensor for the exhaust gases
Put a check sign if the burner
works with an external stop switch
connected to the OD input
with normally closed contact (NC)
Check this box if the controller
comands a pump for
the hot water installation
The internal auger motor
will work 1.5 times longer
than the main auger
Additional seconds for
the internal auger's active time
If checked, every procedure where
FC output was supplied will be
followed by the same amount of
time without any voltage to it
Set this parameter to assure the
accuracy of the statistical information
for pellet consumption.
Check the instructions how to
calibrate the auger motor on page 20.
Check this box if the controller
comands a pump for
the central heating installation
