(Optional) A high temperature pt100 sensor measures the temperature of the flue gases to
monitor the pollution of the boiler's heat exchanger. If the heat exchanger has gained a lot of
soot, the temperature of the flue gases is higher and the boiler works less efficiently.
The universal power supply and the controller's output power allow it to be used both in
110V/60Hz and in 220V/50Hz grids.
High reliability.
The controller NPBC-V3C-1 is 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 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 from the boiler, if necessary. Both blowers' power can be adjusted from the controller.
NPBC-V3C-1 has 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
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 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!
