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.

switch-off phase is activated.
CAUTION

tion of the burner along the entire curve.

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).
