Apex run time programming (1 Viewer)

[Nezw0001]

OK Apex nerds, can someone help me figure out a way to fix things before I leave to Thailand?

Here is my situation. I have my ATO hooked up to saltwater so that replaces water as the skimmer removes it, hopefully its not much volume. My FW is on a timer that I adjust as needed with house humidity.

My skimmer pump is a red dragon that apparently can be controlled by the 0-10v apex output but I haven't been able to figure out an elegant solution to get the programming to work. Here are my asks

1. I would like to be able to shut off the skimmer if my ATO is running too much.
2. I would like to figure out how to use the 0-10v controllability to reduce the skimmer flow if the ATO is running too much.

this system works well as the only downside is if the skimmer overflows I might burn through a bunch of SW but at least I don't dump a ton of FW in. Any ideas all?

Nice! I like how you are thinking.
My first thought was why is fresh water on timer, because how would the ATO distinguish if water needs to be replaced due to skimmer or evaporation. But then I realized you are likely running your skimmer wet ?

I don't run the skimmer very wet, it does have an auto flush that uses some SW, but when it overflows its nice not to have to worry about FW being dumped in.

The difficulty is that there is no way to base something off the amount of time something runs other then the WHEN command. That would move the slider to manual off if something is continually on for longer than a set time. Unfortunately if the item is switching on and off it would not hit the time limit but may be running more than expected.

You could still use it to catch a continually running ATO. You would also need to add a corresponding IF ERROR command in your alerts so you are notified. You would have to manually move the slider back to auto after it fires.

Do you have a salt probe? If so you could shut it off based on that.

From experience, never change anything, especially something critical like this, without at least a few weeks to monitor it before you leave.
