Disappointed with Carrier

I'm disappointed in Carrier. In brief, the new Carrier Infinity system I had installed does not have the "Zone-Off" function that my old system did. The Carrier folks report since I am unhappy that the zone-off function is not available in the new system, I should consider their 100% satisfaction guarantee, and have their system replaced with another manufacture's system. Also, they were quick to "throw the <dealer> under the bus"; Carrier is putting the blame on my dealer that they did not inform me that the zone-off function is not available in the new Infinity system. I have yet to read Carrier’s “replace” guarantee… But, I’m sure it’s not written in my favor.

Any similar experiences, or used Carrier's 100% satisfaction guarantee?

 

What is the problem you're having with the system that you believe would be solved by adding a "Zone Off" function?

 

I have zone(s) that are unoccupied, and do not need heated or cooled.

 

I saw where you posted in another forum that you have four zones and are only using one zone. What percentage of the total house heating & cooling load is the single zone that is occupied? If you don't know that, then what percentage of total house square footage is the single zone?
