Do I need the fancy and expensive "RV" thermostat?

And horribly inefficient. Bottom line, I don't want it *that* bad.

I someday want to try 12 or 24vdc and see if it works on the thermostat I want to use.... But somedays are hard to find.

Hunter battery operated from Walmart, HD, Lowes, Amazon. Good for A/C and heat. Don't get a heat only. Someday you will and to use your A/C. Very easy read direction to install.
