The fan operates constantly. Fuel feeder is
engaged periodically. One period consists of
feeder operating time and pause in feeding
time:
Cycle time operation parameter is located

.
Feeder
operation
time
is
calculated
automatically depending on the required
current power of the burner, feed efficiency
and calorific value of the fuel.
Parameters of airflow output for diffrent
power levels of the burner are available in:

Boiler settings

modulation
You can choose between two adjustment
modes responsible for stabilizing the boiler
preset temperature Standard and Fuzzy
Logic. This mode changes in:

Regulation
mode
Standard mode operation
If the boiler’s temperature reach preset one
then
the
controller
switches
of
to
SUPERVISION mode.
Controller is equipped with boiler’s power
modulation mechanism – which allows for
gradual power reduction when approaching
the preset temperature.
There are three power levels:
MAX/MED/MIN power
Current power level is displayed on the
screen as 3 segmented indicato rat the left
side of boiler’s icon.
Each level can be allocated with seperate fuel
feeding times and Air flush intensity which
influence on actual boiler’s power level.
Power levels parameters are available in the
menu:

Output
modulation
The controller regulates burner’s power with
which it operates depending on preset
temperature
and
defined
hysteresis
Hysteresis H2
and
Hysteresis H1
.
It is possible to configure volumes H1 and H2
in such a way that modulation is done
without intermediate position. That means
switching from MAX to MIN with omission of
MED power.
