ATO single + back up

I realized I posted in the wrong forum, so I've reposted this here:
- I want to set the ATO to single, using ATO Low to trigger the pump to feed the water to top off my sump.
- I want to set the ATO high as a backup switch, so if the first ATO low fails, the second will stop any overflow from happening.
Does anyone know what I'm going to need to do besides set my ato to single ato?

Isn't that the behavior for standard ato?

Wow. I could have sworn I had posted a reply on you other thread.
Code: Select all
ReefAngel.SingleATO(true,Port1,60,0);
if (!ReefAngel.HighATO.IsActive()) ReefAngel.Relay.Off(Port1);

I posted in the wrong forum. Thanks Robert! I figured that was the way to do it, but didn't know if there was anything else special that needed to happen.
Thank you

Robert, I think this only works when both switches are pointed down. If I want to have the low point down and the high point up, just like how the standard ato switches are setup, do I remove the exclamation point?

I did something similar. I wired the two switches in series. That way I have backup protection using only one ATO port. I used the other ATO port as a failsafe to switch off my return pump if the sump gets too low.

Edit: Fixed switch logic.
