I have read a couple of references in this forum that stated that Trane: (1) previously recommended against using the XL16i in a zoned system but had since changed their mind, and (2) still recommends not using the XL16i in a zoned system.

Are there are any Trane experts here who can answer this? I am finalizing a new residential install for myself and would like the latest on whether or not the XL16i is a viable option for the zoned system.
