Start-up, calibration and operation of the burner
7.5.1 Resetting the control box
To reset the control box, proceed as follows:
– Hold the button down for between 1 and 3 seconds.
The burner restarts after a 2-second pause once the button
is released.
If the burner does not restart, you must make sure the limit
thermostat is closed.
7.5.2 Visual diagnostics
Indicates the type of burner malfunction causing lockout.
To view diagnostics, proceed as follows:
– Hold the button down for more than 3 seconds once the red
LED (burner lockout) remains steadily lit.
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, accord-
ing to the coding system indicated in the table on pag. 34.
7.5.3 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 lockout) 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 intermit-
tently with a higher frequency: only now can the optical link
be activated.
Once the operations are done, the control box’s initial state must
be restored using the resetting procedure described above.
The sequence of pulses issued by the control box identifies the
possible types of malfunction, which are listed in the table on
pag. 34.
