Resetting the control box and using diagnostics

The control box features a diagnostics function through which
any causes of malfunctioning are easily identified (indicator: RED

To use this function, you must wait at least 10 seconds once it
has entered the safety condition (lock-out), and then press the
reset button.

To view diagnostics, proceed as follows:
– Hold the button down for more than 3 seconds once the red
LED (burner lock-out) remains steadily lit.

Software diagnostics

Reports burner life by means of an optical link with the PC, indi-
cating hours of operation, number and type of lock-outs, serial
number of control box etc.
To view diagnostics, proceed as follows:
– Hold the button down for more than 3 seconds once the red
LED (burner lock-out) remains steadily lit.
A yellow light pulses to tell you the operation is done.

The sequence of pulses issued by the control box identifies the
possible types of malfunction, which are listed in the table on
page 24.
Burner calibration
The control box generates a sequence of pulses (1 second
apart), which is repeated at constant 3-second intervals.
Once you have seen how many times the light pulses and identi-
fied the possible cause, the system must be reset by holding the
button down for between 1 and 3 seconds.

If the burner does not restart, you must make sure the limit

A yellow light pulses to tell you the operation is done.
Release the button once the light pulses. The number of times
it pulses tells you the cause of the malfunction, according to
the coding system indicated in the table on page 24.
Release the button for 1 second and then press again for over
3 seconds until the yellow light pulses again.
Once the button is released, the red LED will flash intermittent-
ly with a higher frequency: only now can the optical link be ac-
tivated.
Once the operations are done, the control box's initial state must
be restored using the resetting procedure described above.
