Electronic pellet burner controller - NPBC-V3M
Automatic clean up - Auto Clean Setup – The burner has an option for Automatic cleaning
procedures. During these procedures, the burner turns off, cleans itself and automatically turns on
again. The parameter in this menu indicates the burning time between the automatic cleaning
procedures. If the burner turns off between two cleaning procedures for some reason (for example, it
has reached the set temperature, or the thermostat has activated, or else), the timer until the next
procedure starts from 0 again.
Hardware Setup – gives the opportunity to deactivate the internal auger motor (Burner Feeder) and
the additional cleaning fan (Cleaner Motor), if the burner does not have these options. If Tstat NO is
checked, the room thermostat will be with normally opened sockets.
Burner feeder active time set - Burner Feeder – adjust the internal auger motor's (if any) active
time. It turns on at the same time with the main feed screw motor. The active time of the burner feeder
depends on the percents of the active time of the feed screw motor and the additional constant time.
For example, if the feed screw motor works for 5 seconds for each cycle, the percentage setting is
150% and the additional constant time is 5 seconds, then the internal auger motor will start spinning at
the same time with the feed screw motor and will stop in 7.5+5=12.5 seconds. The point of this
settings is to provide enough time for the pellets to move from one end of the burner feeder to the
other.
