My ATO is not the expansion, its the the one that came with the RA unit. The valve goes up and down and I do hear the click when the valve is at the prescribed water level. However, the pump isn't shutting off. and then the time out trips, the red light comes on the RA unit, the pump still is running. Here is my code: is something wrong in not shutting off the relay?
Thanks for any help

Well, it happened again, poured two gallons of kalkwasser into the tank before I caught it. Put the whole tank in shock, had to run to the local fish store, buy 25 gallons of water and do an emergency water change. Nothing dead so far, but this ATO will go in the trash.

Are you getting bus locks?

No, no bus locks. It's like there was a siphon going on, but the return hose was above the water level of the sump, it wasn't in the water. I am going to check the Tom's aqua lift pump I was using, maybe the diaphram was stuck open?
