SOFTWARE DIAGNOSTICS

Reports the life of the burner by means of an optical link with the PC, indicating 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.
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 intermittently with a higher frequency: only now can the opti-
cal link be activated.
Once the operations are done, the control box's initial state must be restored using the resetting procedure
described above.
