In terms of HVAC standards, the Trane supports pretty much everything you can imagine. I just wish it didn't have such a huge screen. You don't need that for a connected device when you plan to primarily connect to it from another device. But if you planned to use it more stand-alone, I suppose the larger screen is a plus.

I'm still in love with Nest's physical design, I just think they didn't include enough in it to justify the price nor the praise - much of it can be addressed in software, but not all of it.
