Help with apex programming for skimmer

[mpekoske]

Can anyone help me with how to set my skimmer so it turns off when ph hits 8.4? I’m new to apex and can’t figure it out... attached is how it’s set up now

Change the Control Type from "Skimmer" to "Advanced". This will reveal the underlying program code created automatically. Then add this line to the bottom of the program:

If pH > 8.39 Then OFF
