Electronic pellet burner controller - NPBC-V6T-2
Controllers NPBC-V6T-2 are designed to control burners , using increasing or decreasing the
temperature of the exhaust gases for detecting ignited or extinguished fire. The measuring is with
the high temperature sensor pt 100, mounted in the beginning of the chimney. The dosing of the
pellets fed to the fire is done by pulse switching on the auger from the pellet tank. The user can set
the cycle (time between two switches) and the time length when the auger is switched on. The
module can control an optional auger motor that forwards the falling pellets to the burning
chamber. The controllers run two fans: one that provides air to the burning chamber, and the other
is additional fan for taking out the exhaust gases from the boiler if it is necessary. The both fans'
powers are smoothly modulated by the controller. To control the burner, power can be used with
the temperature of the water in the boiler, the signal from RT input from the universal room
thermostat or temperature measured in the room. There it is installed additional control module
with room thermostat function NRC-8-SV. It is possible to control the exhaust gases temperature
with Pt 100- high temperature sensor. This temperature can activate alarm when the preset limit is
reached to decrease the power of the burner and to extinguish it. The controller can control
mechanisms for additional cleaning of the burner with powerful fan, compressor or linear moving
mechanism. The controller run two circulation pumps for Heating installation for the water heater
and for Domestic hot water.
All of the controlled mechanisms must work on 220VAC or 110VAC mains power supply!
Important:
The controller NPBC-V6T must be powered at least 4 minutes, for normal operation of the clock
support system and the current state of the burning process when the power supply is switched off!
