Operating control parameters of the burner
The control board of the burner has factory preset operating parameters
values, which in common case are satisfying the requirements of a system and
does not require any intervention and variation. The optimal operating
conditions, however are achieved by adjustment of the thermal capacity (by
adjustment of the thermal capacity potentiometer) and adjustment of the air flow
rate control flap.
The control board is equipped with various LEDs (with different colors),
which indicate the operating mode of the unit and its adjustment indexes values.
The adjustment of the operating parameters of the burner should be performed
by a trained authorized technician.

Description of LED indication (positioned on the control board of the
unit):
Green
and
yellow
LEDs are blinking in series mode – they are indicating
operating information
for the status of the burner. This information could
be utilized in order to analyze the operating mode of the unit. For example
the number of blinking signals of the
green
LED, indicates the index of
the potentiometer number (P1 … P5), which are positioned on the control
board. The number of the following
yellow
LED blinking signals
indicates the value of the position of the appropriate potentiometer. The
correspondence between the number
yellow
LED blinking and
parameter’s value are given in Table 5.1. The
red
LED is active when the
photosensor senses presence of the combustion process.
EXPLANATION :
the emitted visible light from the above mentioned LEDs
could be monitored through the transparent window, positioned above the
control board of the burner, installed on its top cover.
Table 5.1. gives detailed information about the number of LED blinking
signals and the corresponding values of the operating parameters of the burner’s
control board :
Symbols :
P1
– potentiometer, which defines the operating period for transporting initial
fuel doze to the combustion chamber of the burner;
P2
– potentiometer, which defines operating period for supplying fuel at
nominal load;
