Electronic pellet burner controller  - NPBC-V6T-2

Flame detection

 - It is set how much the temperature of the exhaust gases shoud be increase or

decrease for detecting fire or extinguished fire and what is the maximum time after stopping the
pellet feeding after which fire should be considered for extinguished.

Power   Modulation  

–   Setting  the   difference   between   the   set   temperature   and   the   boiler's

temperature   for   each   power   level.   Here   are   set   the   operating   conditions  for  the   power  of
''Suspend", waiting time and maximum overheating above the set temperature, after that the burner
is extinguished.

Room thermostat -  

  Set the time for decreasing  of  the power level when the burner is on CH

priority mode.  In this mode, when there is an active room thermostat, if the burner works with
power P3, it will wait the set time for P3, and if the thermostat is still active it will go to power P2.
If the thermostat remains activated for the time set for P2, it will switch to power P1. After P1, if
the thermostat is still active, the burner switches to “Suspend” power level and works on it for as
long duration as it is set in the menu Service Settings 

»

 Power Modulation, parameter Duration.

After the maximum time for  suspension  has expired, if the thermostat remains activated, the
burner is extinguished.
When activating line 

"NRC8-SV

 mode", the modulation of the burner power in "

Heating

" mode

is allowed, depending on the set and measured room temperature in the additional control module
with function from the room thermostat NRC8-SV.

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 boiler's temperature gets

higher than the set temperature

with 8°C, the burner turns off

immediately.

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

The burner will work

in Suspend mode

  maximum 20 minutes,

then it will turn off

The fire will be considered

for alight, if the temperature

of the exhaust gases

increase with 20°

The fire will be considered for

extinguished, if the temperature 

of the exhaust gases

decrease with 40°

The fire will be considered

for extinguished, if passed 

5 minutes is without fuel

feeding.
