If ph >8.40 then off; not working. Apex ATO programming

[Miami Reef]

I’m trying to make my apex close my ATO if ph reaches above 8.4

Someone help please.

Are you missing a space between > and 8.4?

This worked. Thank you!

You also want to add

Min Time 030:00 Then OFF

So your ATO doesn't flicker between ON and OFF really fast when you reach this threshold. You can adjust the timing, but 30 minutes is likely a good starting point.

That will do what exactly? Minimum 30 then off? Does that mean once the ph hits 8.4 the ATO will turn off for 30 minutes? It’s not really making sense to me because it feels like it should say min time 30:00 then on?

Ps: I am extremely new to coding with apex, so I’m just trying to understand what I’m doing.

Means if the pH hits 8.4 and the ATO turns off, it can't turn back on again until both the pH is below 8.4 AND at least 30 minutes have passed.

Does this look right?

Looks good

Just to clarify for you.....

It wouldn't be "then ON", as you already have the outlet turning on by the "Set ON" command. Hence why it's "then Off".

Apex evaluates coding from top to bottom. So the set command will tell it to turn on, but the min time command will tell it to stay off. The last statement that results in a "true", will be the command the apex follows.

omg. I had same solution but didn't mention it because I thought it was too obvious!
