One potential thing that could answer your question. If you are comparing results with and without AC connected I assume your 12v system is not being charged. Without the converter running the lower 12v system voltage may affect the control circuitry for better or worse, including the thermistor circuit. Pure speculation on my part.
During my testing, 120V was being supplied to the entire trailer, the fridge as well as 12V via the batteries, just as if it were running as it normally does. Only thing different is that the leads for the heater were supplied 120V separately and without being regulated by the control board.
Thanks for the comments.
