I got an email from kkontrols this a.m. You were correct. Moving a wire is all that is needed.
Im going to be using a mastercool portable evaporative cooler in the grnhouse during summer, only need a very small heater during the coldest part of our winter, so this looks like the unit for me. Im well within the load range, as the evap cooler simply runs a large sqirrel cage blower and small water pump, no compressor to turn, so the amperage rating is a-ok for my application.
Whew, that saves me big $$$!
