Rated 4 out of 5 by BLee Happy to have a properly cooled upper floor
Since moving in this house has never had a comfortable upstairs, but with the iHarmony zoning system we finally get proper cooling on the second floor.
Our zoning system was installed along with our XC25. My only complaint is that the really nice dehumidification features of the XC25 are basically turned off when using zoning. That's unfortunate as it seems that there should be a way to get constant dehumidification on both zones when the cooling needs have been met. Here's hoping a future software update will enable that feature on zones.

Rated 4 out of 5 by brjiii iharmony has great features and options
I have installed the harmony lll in many homes and was reluctant to change to the I harmony, ounce I installed my first I harmony I was hooked. Only 3 minor things I would like to see in future changes 1) dehumidify ability with I comfort stat zone while in zoning option. 2) wireless slave stats. 3) ability to use I comfort stat for all thermostats.

Rated 1 out of 5 by txef Terrible product
I was sold this product for a two story house instead of a 2-unit zones system. It was way more expensive and has been nothing but problems. Dampers break, motors break, control panel broke. It is the worst product. Lennox you have a serious problem with this Harmony system. Most technicians don't even know how to fix when it breaks, and it breaks at least 3-4 times a year. I would not recommend buying it.
