If a HUW container needs to be filled in
OPERATION mode at pre-set boiler
temperature, which is lower than the value
required to its filling, the regulator will
automatically increase preset boiler
temperature for the time of HUW container
filling
8.6 OPERATION in I.FuzzyLogic mode
This mode may be activated in the menu:
Regulation mode
Using the function of IndividualFuzzyLogic,
settings of which are individually adapted to
the given boiler allows obtaining optimum
combustion process, which is more
environment friendly, supports fuel savings
and in most instances eliminates the need to
adjust regulator parameters.
During operation with use of
Individual Fuzzy Logic algorithm, parameters
of feeder operation (Feeding Time, Feeder
Interval) and blow-in output needn't be set-
up. Three-stage output modulation is inactive
– the regulator automatically sets feeder and
fan control parameters in a stepless manner.
In Individual Fuzzy Logic mode, the regulator
strives to eliminate the need to bring the
boiler into SUPERVISION mode, and to
produce exactly as much heat as CH system
requires. Change-over to SUPERVISION
mode occurs once the actual boiler
temperature has exceeded the preset value
by 5 °C.
Please note Individual Fuzzy Logic algorithm
is adapted individually to the given boiler and
fuel type and may work properly only with
this boiler and fuel. Therefore
IndividualFuzzyLogic mode has to be
activated by the boiler manufacturer in
accordance with sec 26.1. In case this mode
has not been activated, when attempting to
change the mode, a prompt ’FUNCTION NOT
AVALAIBLE’ appears.
Change of settings of Individual
Fuzzy Logic algorithm.
Sometimes, depending on the fuel quality,
air flow has to be adjusted in
IndividualFuzzyLogic mode.
The user may change the settings as follows:
BOILER SETTINGS > Output Modulation
> FL airfl. correction
BOILER SETTINGS > Output Modulation
> Min.boil.output FL
BOILER SETTINGS > Output Modulation
> Max. boil.output FL
The range of setting correction has been
deliberately limited. Change of FL airfl.
correction setting is not recommended if
combustion process runs properly i.e. no
incompletely burnt fuel particles are
present. In case of poor fuel quality, when
presence of incompletely burnt fuel particles
is obvious, amount of supplied air may be
increased. If the fuel is very dry, causing
high combustion rate and too intensive
furnace burning-out, the value of FL airfl.
correction may be reduced.
In Individual Fuzzy Logic regulation
mode, the values of parameters
related to blow-in output and
feeder operation and standstill
times available in menu: BOILER
SETTINGS > Output Modulation
are not used by regulator operation
algorithm. These settings are used
only in STANDARD mode.
When using IndividualFuzzyLogic
control, fan baffle should be fully
opened, and the boiler has to be
clean. In case of required fan or
feeder replacement - use identical
types of both pieces of equipment.
Once the actual boiler temperature has
exceeded the preset value by 5⁰C, the
regulator automatically enters SUPERVISION
mode.
