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.
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°
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.
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.
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.

The fire will be considered
for extinguished, if passed
5 minutes is without fuel
feeding.
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
