Hi. having issues with ATO not working right. After hooking up float switches and testing the ATO I found the main sensor wasn't working and the back up sensor would turn it on and off. I checked and double checked my wiring it was right so I switched the sensors around so the back up is the main. The ATO would work when testing but after 10-20 minutes the ATO icon keeps going red even after resetting it many times. I tried running ATO in test mode but the icon still goes red.
