Can I program my skimmer to turn off if my cor pump is under a certain value? I have all my feed modes turning off my skimmer appropriately but the idea is a fail safe in case someone hits the speed controller and slows down the flow, I don’t want the skimmer overflowing. I tried programming it into the skimmer using “if output returnpump < 65 than off” “if output returnpump less 65 than off” if output returnpump [<] 65 than off” and then tried on cor “if < 65 then output skimmer off” and the system rejects everything. Any ideas?

The correct syntax is:

If Output returnpump Percent < 65 Then OFF

See my Apex Command Reference article for the exact syntax of every available Apex command:

That worked! Thanks! If I add a defer 5 min statement would that mean the system would wait 5 min AFTER the cor returns to 65 to turn back on?

Yes, if you use:

Defer 005:00 Then ON

This would cause the skimmer to remain off for 5 additional minutes after all the conditions (not just the COR) that turn it off have been cleared. See my tutorial on Apex Timers for more details on Defer:
