it's possible inverse AWC ?

hello, I have a big problem with my AWC .

My problem is that the sensor must be below the 2 sensor 1 .

my normal water sensor ( sensor 1 / Auto top ) works to 21cm .

I want to change 11 cm of water ( between sensor 1 and sensor 2 ) (either 70L which is my reserve of fresh water )

when I click on " water change " skimmer and pump up therefore stop the water rises to 33cm .

I want my water down and then up to the sensor 1 to sensor 2 and not awc standard , the water goes down at 2 and at 1, I want to do a reverse sensor awc but I can not

So I'm stuck , how can I do?

I'd like to do the same please.

Same here :-)
