Burner Operating Fault 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 blinks and identified the possible cause, the system must be reset by holding the button down for 1 - 3 seconds.
