6.6.1.6 Manual lockout procedure
If necessary, it is possible to manually block the control box and,
consequently, the burner, by pressing the key "i/reset" simulta-
neously with any other key of the operator panel.
With the selector " 0-1 " (Fig. 33 at page 33), the
burner does not stop immediately, but the switch-
off phase is activated.

6.6.1.7 Manual operation procedure
After the adjustment of the burner and the setting of the points on
the modulation curve, it is possible to manually check the opera-
tion of the burner along the entire curve.
Example:
the burner is working at the requested load percentage: 20%.
P
Press the "F" key for 1 second: " LoAd" is displayed and the load
percentage flashes.
P
Releasing the "F" key, the standard visualisation appears, with
the current load percentage flashing: this means that the burner
is working in Manual mode (any outside adjustment is excluded
and only the safety devices are active).
P
Keep the "F" key pressed and, with the keys " +" or " –" , increase
or decrease the load percentage.
P
To exit manual mode, press the keys " + " and " - " ( ESC ) simulta-
neously for 3 seconds: the burner will work in Automatic mode
and the output will depend on the thermostat/adjustment pres-
sure switch (TR).
