I am going to be getting into programming the FX line of controllers. Is it hard to program these controllers? Im going to be using an FX16. I have experience with programming and configuring the DX9100, UNT controllers with HVAC Pro, BACnet field controllers with CCT, and SCT.
Also, what is different about the FX40? I always see the FX20/60 being compared, but it seems like the FX40 is somehow different?
