    Thanks for the feedback, guys. I am leaning towards the York for now to use with my existing wifi t-stat. Operating like NC described would work very well for me. And if I ever wanted to step up...

    The Trane logic with the generic 2 stage T-stat sounds like just what I am looking for and my 3M stat does control 2 stages of heat and cool. I am in MD so winter temps can vary widely and there are...

    Those communicating systems seem like they would produce the most accurate response to need. But to do that they have to use the proprietary thermostats. Maybe they also have an algorhythmic mode...

    My stat has a time adjust feature but i find it easier just to set the actual time I want the thing to kick on than to have a time when I want the temp to be X. It just isn't that critical.

    How does a modulating furnace modulate?

    I am looking to upgrade my HVAC and going through the usual research between single stage, 2-stage, and modulating furnaces. I have read some of the threads here on this already.
