So, I have the following setup:
Lennox XC 21 Air Conditioner.
Lennox CBX32MV Variable Speed, Multi-position Air Handler
Harmony III Zoning----Two Zones.
How can I tell if I am getting the benefits of the Two Zone system? Should the stat contain certain wires? Is this done at the zoning board? Thank you!
FWIW, the house had a one zone system prior to having this new system installed. Thanks!
