Hello

Apologies if it's been covered before, I did try searching Google and here but with no luck

I have a Red Sea Reefer with its own ATO which is manually activated via a float valve. Therefore, I need my AWC to be automated with the filling part first and then the drain. This is going to be done via a Profilux 4 and a Maxi Doser.

I've achieved this by setting the Drain socket as the filling pump and the Fill socket as the Full socket.

Just trying to test this and the pump successfully filled the tank up until the high sensor un-ticked, and then the draining pump started under the Fill routine.

My issue is that as soon as the high sensor drops and becomes 'ticked' again, the whole water change function stops as completed.

How do I get it to continue until the lower sensor is back in its original position?

Even if I had this setup to drain first, it would be stopping as soon as the lower sensor is reset rather than the original sensor.

Many thanks
Scott
