Need quick fix for Intellitec EMU-2
Problem: energy management unit (EMU-2, by Intellitec) has failed. The device prevents both rooftop AC units from running at the same time when plugged in to shore power, to prevent overloads.
This part is obsolete, being from a 15-year old, currently orphaned coach, and my conversations with Intellitec have not indicated that there is a comparable replacement available.
My shop's proposed solution is to rewire the whole coach for 50amp power, which is a great deal more expense than I'm willing to go to at the moment, especially as we are scheduled to leave for an Amazon workamping job in less than two weeks.
Of course, we won't be very happy with out AC or a heat pump, either. Does anyone know of a workable (preferably inexpensive) repair or replacement for a defective EMU-2?
If not, is it possible to wire a simple toggle switch, allowing manual selection of front or rear AC units? I know that this won't allow both to run at the same time, but we've never needed both at the same time. It seems like this would be the easiest and simplest solution, but I am neither an engineer nor an electrician, and so there may be some issue I'm overlooking.
Any advice is appreciated. It's extremely warm and only getting hotter...
