    I have a 2 story house on a single Lennox unit. I am experiencing the typical "hotter upstairs than down stairs" syndrome. I am considering installing a Lennox LZP-2 zone system to divide the upstairs and downstairs into 2 zones. My unit is a split system heat pump with easy walk-in access to the air handler and trunk ducting. There are two trunk lines; one for upstairs and one for downstairs already. Anyone have a ballpark idea of what this would cost?

    The site rules forbid us to give any pricing info.

    Since prices vary from area to area.

    what ever the price it would make a big difference in comfort. with ducts already split it should be a piece of cake to install dampers and wire up controls.

    I have the exact smae situation and have a honeywell EMM-3U controller ready to go in. I have a 12" for the upstairs and 2 10" for the downstairs.

    The upstairs is easy- one thermo- one damper. But how should I hook up the downstairs?

    1. Both dampers run off of one zone connection (possible overload?)
    2. OR wire the downstairs thermostat to the controller so that it looks like 2 thermostats running exactly the same mode all the time. then it would control 2 dampers on their own connections.

    Thanks in advance-

    Any damper recommendations are VERY welcome, also.
