Using AC3 for ATO

[pontiac2002gtp]

Does anyone use there AC3 to control there top off? If so I would like some info on how it works and what you need to make it work. Thanks for any info.

You may want to try in the Neptune forum. There are several active threads already there on this subject. I don't use mine for ATO but I'm lpaning on hooking up some float switches to my AC3 for overflow safety.

I have my ACIII controlling my ATO, I use the Neptune break-out box to plug into my controller and then I have a float switch plugged into the break-out box.
