I currently have a Trane 5 Ton XL14i single stage AC with a variable speed furnace controlled by a XT302C thermostat.
I wish to upgrade to a digital thermostat and see the Trane TCON803 as the replacement. The Honeywell TH8320 appears to be the same thing. Im sure that Honeywell is the OEM for Trane.
My question is: Is there any difference between the two other than the logo?
I am also aware (from other posts on this site) that there is a difference between the retail store and Pro version of the Honeywell VisionPro, How do I tell the difference?
