    Looks like a fun project. I went to an old class on this type system about 10 years ago. Surely I would want a refresher before tackling it now?

    Its all the same. The central controller has changed and they've come out with some ERV/HRV

    Very nice! Nice to see a DP switch across the unit, I wish everyone did this.

    Just out of curiosity, how thick is the insulation on the line sets? We've been having an internal debate about the value of insulation on the vapor line during heating mode.
