Glad you have the thermostat problem resolved.
Our Epro 19FD has a battery cut off switch. I don't know if all the other models have this feature (Our is under the propane tanks). This comes in handy to kill all power to the trailer.
A lot of the newer Epro's/GeoPro's have solar so "ghost" power draws are not all that big of a deal. However, I always like to know that the power is truly off when I leave the trailer parked or stored.
