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.

burner does not stop immediately, but the switch-
off phase is activated.
CAUTION

tion of the burner along the entire curve.

Releasing the key " F " 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).

or decrease the load percentage.
P
To exit manual mode, press the keys " + " and " - " ( ESC ) simultane-
ously for 3 seconds: the burner will work in Automatic mode and

switch (TR).
