Progressive EMS-HW30C Modifications
A couple of years ago I bought a used TRC 34370 portable surge protector from an elderly couple who had sold their Airstream and retired from RVing. Although the TRC was a portable unit I wired it in...

Never considered putting a switch to change the time delay I just leave it on the shorter setting as my A/Cs have a built in time delay so that is not necessary.
It's surprising to me that not all A/C models designed for recreational vehicle use don't have built in time delay as it's so critical to the unit's longevity. From Page 12 of my own Dometic Brisk II owner's manual - "Wait at least 2 minutes before restarting the compressor when it has been manually cycled off with either the selector switch or the temperature set lever. Other-wise, compressor will quick-cycle and could result in compressor or supply circuit over-load." In this statement the manufacturer is obviously assuming "normal operating conditions", meaning incoming source power will always be stable, but of course that's not always the case ... in my own case I'd say there hasn't been a summer yet where I haven't experienced fluctuating low voltage and power brownout due to overload of the power grid system that would otherwise play havoc with my A/C. Since only a very small percentage of RV owners seem to be willing to invest in some sort of surge / EMS protection that leads me to believe that not many are aware just how dangerous not using a timed delayed EMS in this situation could be to the longevity of their A/C unit ... thankfully I'm no longer one of them! :W
