Electronic pellet burner controller – NPBC-V3C-1/ NPBC-V4C-1/ NPBC-V4E-1
after every cleaning procedure the controller will wait for the actuator to get back for as long as the
output has been supplied with power during the procedure.
Flame Detection
– Set the level of illumination measured by the photo sensor and for how long the
controller has to wait until the ignition and extinction are successful.
Power Modulation
– Set the difference between the set temperature and the boiler's temperature for
each power level. When it is more than the value for
P3
, the burner works on 3
rd
power level. When it
is more than the value for
P2
, but less than the value for
P3
, the burner works on 2
nd
power level.
When the difference is between the values for
P1
and
P2
, the burner works on 1
st
power level. When
it's less than the value for
P1
, the burner woks on Suspend power level. While on Suspend, if the
difference between the set temperature and the boiler's temperature increases enough for 1
st
power
level, the burner automatically switches to it. If the difference doesn't increase, the burner works on
Suspend power level for as long as it is set in the parameter
Duration [min]
. While on Suspend, if the
temperature of the boiler is still increasing, when it gets higher than the set temperature with as many
degrees as set in the parameter
Overheating
, the burner will turn off immediately.

The ignition is successful, if the
photo sensor measures more
than 100 for more than 20 seconds
If the difference between the
set temperature and the current
temperature of the boiler is more
than 10°, the burner works on P3
If the difference is between 5°C
and 10°C, the burner works on P2
If there is no change in the
conditions, the burner works on
Suspend power level for
20 minutes and then turns off.
If the boiler's temperature gets
higher than the set temperature
with 8°C, the burner turns off
immediately.
If the difference is between 0°C
and 5°C, the burner works on P2.
Otherwise, it will work on
Suspend power level
If the burner works on P3 power
level when the thermostat
activates, it will work on
this power level for 60 seconds
