The setpoint values made with an empty vessel are not overwritten by
automatic setting while the vessel is full. You can update adjustment
with the vessel full as often as you wish. (Automatic setting with the
vessel full will return the “full“ setting to the factory default.)
If adjustment is not possible (e.g. “empty“ signal strength and
“full“ signal strength are almost the same), the red LED flashes
after setting (in addition the function check output provides a
2Hz signal).
Press the button briefly (= acknowledgement) and repeat setting.
