One was tucked into 82 gal tank and the other was inside the insulation

The problem there is that all thermistors are slightly different. A 10k thermistor made by company X does not have the same resistance at 100 degrees as company Y's thermistor.

Perhaps they are close enough. I just haven't done that much research on it yet.
