How get the ATO work with 2 sensors ?

Im about the give it up!
In my osmostank i want 2 sensor at diffrent highst, 1 to say its empty switch socket s1 on for filling it up, sensor 2 will tell s1 to switch of beacuse its full.
I tried to set it up and im lost, both sensors do the same thing, so when the water level drops it triggers sensor 2 to fill up and 6 cm later in the tank its switches of because the level is high.
The sensor in the bottom is never used, and my Ro unit goes for very short periods.

Can i do something else to program this so its really work ?

I think from what you describe you rather need the Min/Max control - look at this:

Min/Max control
Two sensors 2 work together to control a water level. Sensor 1 works as maximum-switch, sensor 2 as minimumswitch.
As soon as sensor 2 registers a too low level, the switchable socket with function Water fill is switched on.
When the water level reaches then sensor 1, the switchable socket is switched off again.

Hi carolin, yes i have it setup like min and max now, but both sensors works the same, sensor 1 register low and high level same as sensor 2.
Have i missed something in the setup ?

look at theese pictures. On socketfunction S5 is the socket the controls the magneticvalve to my RO unit.

If you select "Fill water" as socket function, without "ATO only" - does it work then?

ill try.

Nope, it wont work, when the waterlevel drops under both sensors it doesnt switch on the socket.
Why is this so hard ?

Please post again all settings of the level settings/ details min-max-control /sockets - thanks.

you need Min-Max Control

select the Max-sensor for sensor 1, the Min for sensor 2
use socket function "fill"
