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 LED).
To use this function, you must wait at least 10 seconds once it has entered the safety condition (lockout), and then press the reset button.
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 identified the possible cause, the system must be reset by holding the button down for
between 1 and 3 seconds.
RED LED on
wait at least 10s
The methods that can be used to reset the control box and use diagnostics are given below.
CONTROL BOX RESET
To reset the control box, proceed as follows:
Press and hold the button for 1-3 seconds.
-
The burner starts up again, 2 seconds after the button is released. If the burner does not restart, make sure the limit thermostat is closed.
In the event of a burner lockout, more than two consecutive burner reset operations could cause damage to the installation. On the
third lockout, contact the Aftersales Service.
If further lockouts or burner faults occur, interventions must only be made by qualified, authorised personnel (as indicated in this man-
ual, and in compliance with the laws and regulations currently in force).
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, according to the coding system
indicated in the table on page 15.
SOFTWARE DIAGNOSTICS
Reports burner life 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 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 intermittently 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.
