    I was wondering if anyone knows if you have a two stage compressor that sends a signal to the furnace where do you put that wire(blue)when the zone board controls the variable speed furnace not the furnace

    We put a few of these on a couple of years ago. Pain in the arse for a heatpump as I recall. Not like other zoning. Call the tech rep guys for specific questions. While Lennox sucks for getting warranty and replacement parts for sometimes. They do have decent tech guys. I guess they need it.
    I like DIY'ers. They pay better to fix.
