Water level managment GHL

[Wyou]

My attempts to understand the logic behind the GHL water level control have been unsuccessful so far. Maybe in some scenarios it works successfully, but I don't understand how to do it in my case.
I have 2 level sensors. I want to when I change the water (it's drain pump which is connected to the 4 socket) the heater (Socket 2) to turn off (let it turn off always when the water is lower than the upper sensor), and when the lower sensor is reached the drain pump will turn off and not turn on again until I start the water change process again.
How to do it?

Thx Gael!
But I have 2 physical sensors - but GHL shows 4!

And more - Which function (drain water/ato/awc/flow sensor alarm/pump) should I put in Programmble Logic so that when I have a sensor the top sensor does not touch the water?

Hi,

The purpose of all those level sensor functions are explained in the ProfiLux 4 Programming Guide.
See page 63, section 6.1.

For a AWC setup, you will find the instructions for that here:
