Zen Thermostat - Data Wire?

My new home has a Trane tzone950ac52za (I don’t believe I can integrate this into Smartthings), and I also have a Zen thermostat from my old home, but I am not sure how to hook it up. The Trane is hooked up with a D (data) wire, and I don’t believe my Zen can use this. Anyone know how to:

  1. Integrate the Trane into Smartthings?
  2. Hook up the Zen with a D wire?

I’ve included some pictures of the wiring as well.
