Resetting the control box and using diagnostics

The control box features a diagnostics function through which any causes of malfunctioning are easily identi-
fied (indicator: RED LED).
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.
The control box generates a sequence of blinks (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 between 1 and 3 seconds.
