    Trane UCM

    Can you tell by looking if a UCM is Comm4 or Comm5? I thought that might be marked on the circuit board at the comm terminals, but no.

    If it is comm 5 it will hae a neuron ID, usually has a sticker that has it also. If it is comm4 or below it will have dip switches for setting the address.
