Meaning of ON/OFF in the Min Time and Defer statements

[jgvergo]

Can someone explain the meaning and behavior of the ON and OFF part of the Min Time and Defer statements? iamchadster posted this explanation in another thread: "Think of it this way in your head. Replace the word "then" with the word "is". So you think of it like "Min Time 020:00 IS on"

I interpret that to mean that if I write this statement "Min Time 030:00 Then ON" it means that the Outlet will be on for at least 30 minutes. If I write "Min Time 030:00 Then OFF", then there is no minimum time the Outlet will be on.

HOWEVER, I have this statement at the end of my protein skimmer Outlet "Min Time 030:00 Then OFF" which keeps it on for 30 minutes even though the last parameter is "OFF", so I'm confused.

It means ONCE off the outlet will remain OFF for 30 minutes before turning on.
