I'm kinda new here, but we change out them NMCs to the NAE line. The fellas told me that the N30 was the earlier version of the NAE, so if you like the N30 you should like the NAE. They are a very high end device, so you can only get one from a branch office of Johnson Controls. I'm told it's because other comtractors try to program them and screw them up and it gives us a black eye.
