I'm setting up a Tunze ATO for my new system, and from all I've read, the sensor should go in the return chamber. The return chamber is the only chamber of the sump with water level that changes regularly. How is this not a recipe for disaster? With the newer DC variable return pumps, a change in the speed of the pump could change the water level in the return chamber, right? So if I put my return pump in "feed mode" lets say, would it not increase the level of water in the return chamber and set off the "high water" alarm on the ATO? By contrast, if I turned the pump to a higher speed, the level in the chamber would drop, theoretically kicking the ATO on even when it's not needed.
How does this work in practice? Am I over-complicating? TIA
