Here is my programming for my return pump.

Fallback ON
If FeedD 000 Then ON
If Sw1 OPEN Then OFF
Defer 000:03 Then OFF

I use an overflow box. So for extra safety if sw1 is open then that means there is too much water in the display tank so I want the return pump to turn off.
I don't want it to come back on until I check it and if everything is ok I activate feed d and the return pump comes on. Of course the defer is 3 seconds to account for any surface turbulence.

The switch and feed work as it is supposed to but this morning we had a power failure and when power came on the outlet didn't return to on state. When I activate feed D it came on. I want it to automatically come back on after a power failure.

Is there another line I need to add or are the lines in the wrong order?

Thanks ( See if Canreef can fix this before Reef Central) lol
