The OP has a Progressive Industries EMS-HW50C with a user settable delay of either 15" or 2:16 which is set with a jumper on the main circuit board. I've got my own EMS-HW30C currently set with the factory default of 15" for the convenience but once next summer rolls around I'll reset it to 2:16 because the Dometic Brisk II A/C we have doesn't have any built in compressor delay as do some A/C units. It's really annoying as I'd much rather leave the EMS set for a 15" delay but it is what it is and at least the EMS offers me the ability to protect the A/C's compressor whereas without it I can't. :)
I'll bet my 30A unit is also a 15 second delay, just SEEMS like 30 Seconds when your waiting for it to kick in!!!
