    Nest E to Trane mini-split

    I just had a Trane 4TXK38 12000 btu heat pump installed. I want to hook this up to my Nest E thermostat. I have had difficulty finding out how to wire this. Nest says to get a "Nest Pro" to come out and wire it. I live in a rural area and would rather wire this myself to avoid an expensive service visit. I have included the inside unit's wiring diagram.

    As with most mini-splits the controls are proprietary. You won't be able to use a Nest or any thermostat other than what was designed for it.
