INSTALLATION INSTRUCTIONS
19.1 GAS VALVE CALIBRATION FUNCTION
Note:
The function is automatically deactivated after a period of 15 minutes, at the end of which the electronic board returns to
its operating status prior to the activation of the function or prior to reaching the set maximum temperature.
To simplify calibration of the gas valve, the calibration function may be set directly
on the boiler control panel as follows:
a)
hold down the buttons
and
together for at least 6 seconds;
b)
after about 6 seconds, the symbols
lash;
c)
the display shows, at intervals of one second, “
100
” and the
flow temperature
.
In this phase, the boiler works at the maximum heating output (100%).
d)
press
+/-
to immediately set the power of the boiler (100% or 0%);
e)
adjust the
“Pmax/Pmin”
screw (igure 10) to set the burner pressure value as
described in table 1.
To adjust pressure at maximum power, turn the “
Pmax
” screw (ig. 10) clockwise
to increase or anti-clockwise to decrease pressure at the burner.
To adjust pressure at minimum power, turn the “
Pmin
” screw (ig. 10) clockwise
to increase or anti-clockwise to decrease pressure at the burner.
f)
press
+/-
to gradually set the desired power level (interval = 1%).
Press the button to leave the function.
