I am trying to setup ATO using optical level sensors and FMM. The two sensors I am using are behaving the exactly opposite way. i.e. one reports "closed" under water and "open" above water and the other one is "open" under water and "closed" above water. This really messes up the programming. They are not broken, since they both change the "state" (open/close) when moved in and out of water but in exactly opposite direction.
Is there a setting for the optical sensors to change what it should report when under water? I have another FMM and have 4 other optical sensors and I don't have this issue. All sensors there are "closed" under water and "open" above water.
Also, I am using new Apex (2016) and I have latest firmware for base unit and the module.
