Factory settings
After ignition (point
“P0”
), proceed with the calibration of the modulation curve,
starting from the minimum point
“P1”
.
Press the key
“+”
: the display visualises the indication
“P1”
flashing and proposes
the same settings as for point
“P0”
. It is possible to modify this value and obtain a
modulation minimum different from the ignition point.
After adjusting point “P1”, press the key
“+”:
the display shows
“CALC”
for a few
seconds. The control box will automatically calculate the points from “P2” to “P8”,
distributing them in a straight line, assuming for point “P9” the factory setting (see the
table below). These are theoretical and must be checked.
Press the key
“+”
to check if the settings of point “P2” are suitable. If not, modify the
point. Proceed in sequence until point “P9”.
Important:
before moving on from one point to the next, wait for the
servomotors to reach the position visualised on the display.
During the adjustment of each point, work on the air and gas servomotors, without
modifying the position of the gas valve stabiliser.
Halfway through the procedure (i.e. around point P4 or P5), you are advised to
measure gas delivery and check that the output is about 50% of the maximum output.
If this is not the case, work also on the gas valve stabiliser: in this case however, it is
necessary to revise the calibrations of all the points previously set.
Once you have arrived at point “P9”, if the maximum output is not as you wish, work
on the gas valve stabiliser: in this case however, it is necessary to revise the
calibrations of all the points previously set.
At this point, confirm by pressing simultaneously the keys
“+”
and
“-”
(
esc
): the
parameter
“546”
will appear.
If you want to make the burner work on the entire modulation curve, press
simultaneously the keys
“+”
and
“-”
(
esc
): in this way, the parameter
“546”
will
automatically be assigned the value of
100%
and the parameter
“545”
will have a
value of
20%
.
If you want to make the burner work on a part of the modulation curve, modify the
parameters
“546”
and
“545”
according to “
Parameter modification procedure
”.
Press simultaneously the keys
“+”
and
“-”
(
esc
) twice: the display will visualise the
current load position.
