Trane is
set up for 2 stage. Depends on what equipment that you have. Do you know your model #'s?

You should have a 24 volt panel and a zoning panel. These panels would be found near your air handler. They would be obvious. It should be printed on the outside covers. To make any zoning work with a Trane system you have to have a 950 touchscreen color thermostat.

Don't have that thermostat, that I know. I only have Honeywell 8000's. One in each zone. Is that wrong? Who is the manufacturer of the 950? I can look for the panel. I think only one air handler (the larger one) has 2 zones. The smaller one is only one zone. I will have to climb up to the attic to check on the panels there. I'll be back in touch. Thanks, again.
