--> The pump operates in cycles of 5 seconds on / 5 seconds off.
Ensure that the bleed valve is open.
This function can activate itself automatically during filling: if the pressure measured by
the sensor goes from 0 to 0,5 b, the board interprets this as filling and therefore runs the
appliance bleeding function itself to avoid burner ignition when the heat exchanger is filled
with air.
In this case, the pressure indicator on the display flashes.
However if the passage from 0 to 0.5 bar is too fast (less than 15 seconds) the board
interprets this as a parasite and does not run the function.
