to 30%, skipping the 50% output (right side

Operating in FuzzyLogic mode
In FuzzyLogic mode, the regulator
automatically sets the output of the burner in
order to maintain the set boiler temperature.
The regulator uses the output settings
predefined in Standard mode. This mode
does not require setting the H1 and H2
hysteresis.
Note: If only the HUW is heated
(summer mode), it is recommended
to set the regulator to Standard
mode.
After the set temperature is exceeded by
5ºC, the boiler switches to SUPERVISION
mode.
8.7 SUPERVISION
In SUPERVISION mode, the fan and the
feeder are switched on cyclicall at larger
intervals than in OPERATION mode. This is to
prevent the fire from being extinguished.
Supervision parameters can be found in
menu:
Service Settings
→
Burner Settings
→
Supervision
SUPERVISION parameters should be set in
accordance with the recommendations of the
boiler
or burner manufacturer. The
parameters should be adjusted to prevent
the furnace from extinguishing during
intervals.
Parameters should be so selected
that the boiler temperature in this
mode gradually drops. Incorrect
settings may lead to boiler
overheating.
When the supervision time expires, the
regulator switches to BURNING OFF mode,
unless the boiler temperature decreases and
the
boiler automatically switches to
OPERATION mode.
For the setting Supervision time =
0,
the regulator skips the
SUPERVISION mode and enters the
BURNING-OFF mode.
When the Supervision time = 255,
the regulator will work continuously
in SUPERVISION mode, until the
boiler temperature decreases and it
automatically
switches to
OPERATION mode.
8.8 BURNING OFF
The extinguishing process does not occur
when coal is the fuel of choice. When pellets
are the fuel, they are burned off for several
minutes (depending on the set time). After
BURNING OFF, the regulator switches to
STANDSTILL.
8.9 STANDSTILL
In the STANDSTILL mode, the boiler is put
out and awaits signal to resume heating.
A signal to start heating can be:
 decrease in preset boiler temperature
below the preset temperature minus the
value of boiler hysteresis Boiler hysteresis,
 if the boiler is set to work with a buffer -
decrease in upper buffer temperature
below the preset value Buffer loading start
temperature.
8.10 Domestic hot water settings
HUW
The device controls temperature of the
domestic how water - HUW – tank, provided
that a HUW temperature sensor is
connected. If the sensor is disconnected, an
information about lack thereof is displayed in
the main window. The parameter:
