operation cannot be continued automatically
- service crew must intervene. After
removing causes of impossibility to fire-up,
the boiler must be restarted.

OPERATION
In this mode, the regulator operates
automatically, according to STANDARD, or
Individual
Fuzzy Logic
algorithm.
Fig. 8 Main window view during operation.
The fan operates continuously, which is
presented in Fig. 9. Fuel feeder is activated
cyclically. A cycle consists of feeder operation
time and duration of feeding interval. Fan
power and feeder operation cycle are
determined by one of the following control
algorithms.
Fig. 9 Fan and feeder operation cycles.
If, in the OPERATION mode, it becomes
necessary to fill the HUW tank at preset
boiler temperature lower than temperature
required to fill the tank, the regulator will
automatically increase the preset boiler
temperature for the time of filling the HUW
tank.
In WORK mode, an ash removal process is
activated in cycles for a time defined by
Ash
removal time
parameter and then, it is
suspended for a time defined by
Ash removal
break
parameter.

OPERATION in the I.FuzzyLogic
mode
This mode can be activated in the menu:
Regulation mode
The Individual Fuzzy Logic function, the
parameters of which are selected individually
to the given boiler, allows to obtain optimal
combustion
process,
which
favours
environmental
protection,
savings
of
consumed fuel and in most cases releases
the user from the necessity of adjusting
regulator parameters.
During operation with Individual Fuzzy Logic
algorithm, there is no need to set up the
feeder operation parameters (feeding times,
feeding intervals), and airflow power for the
each boiler output level. 3-phase modulation
is inactive - the regulator automatically and
smoothly selects parameters for feeder and
fan control.
In the Individual Fuzzy Logic mode, the
regulator strives to avoid switching the boiler
into the SUPERVISION mode, and to supply
as much heat, as the CH system requires at
the time. Switching into SUPERVISION is
made only after exceeding the preset boiler
temperature by 5°C.
One should bear in mind that the
Individual
Fuzzy Logic
algorithm is selected individually
to the given boiler and fuel type, and it can
operate properly only with the specific fuel
and boiler. For this reason, the
Individual
Fuzzy Logic
mode must be activated by
boiler manufacturer, in accordance with point
pkt. 23.1
If this mode is not activated,
attempt to change the mode will trigger
message ‘Function unavailable’.
Modifying parameters of the
Individual
Fuzzy Logic
algorithm.
In some cases, depending on fuel quality, it
may be necessary to fine-tune the airflow in
the
Individual Fuzzy Logic
mode
.
The user
can change:
Boiler settings > Output modulation >
Blow-in out. correct. FL
Boiler settings > Output modulation >
Min. boiler output in FL
Boiler settings > Power modulation >
Max. boiler output in FL
