Does anyone know what the difference is between econ mode and auto mode on the A/C system besides the auto stop functionality? Does A/C controller toggle the compressor on and off in either of these modes, or does it just change the fan speed? Also, when I set my A/C on 70, does that mean controller will try to achieve 70F according to the internal air sensor? because my internal sensor is usually 8-12 degrees higher than my set temperature. I just had the compressor, a pressure switch, and one of the sensors replaced, and i'm still having some issues with the A/C, that's why I'm asking.
