Right thermostat for a Trane XL15i and XV95 Dual Fuel Setup?

[jordan3757]

Hello all!

New here to the forum, but I have learned quite a bit from reading all of the posts.

I had a new Trane Dual Fuel system installed yesterday. I wish I had read the "how to pick a good contractor" post first! My contractor failed to pull permits (the work included running gas lines in to the house from the meter), did not have the system inspected, and I'm fairly certain did a few things not to code. Needless to say, I have placed a stop payment on the check (and informed them I have done so) until these deficiencies are corrected.

I've learned from reading on here that the Honeywell 8230 thermostat they installed on my system is not the right thermostat, as it can only control one stage of the furnance but could control two stages of heat pump heat if my unit had that (the XL15i is a single-stage system).

They are going to replace the thermostat with a proper thermostat for the system. The supervisor told me it would be a Trane thermostat "specifically for" the unit, but he wasn't sure of the model number right off. That's got me nervous.

I've seen where you guys love the Honeywell ProVision IAQ, especially on Dual Fuel setups. Is this the only thermostat that can truly and completely control my setup to the best of its ability? I've spent a lot of money on this system and want to be sure I'm using all of the features I've paid so dearly for.

What would your advice be on getting the contractor to install this thermostat? Any information you could point me to to prove to them that it is the correct thermostat for my setup would be greatly appreciated.

Thanks in advance for your help!

Trane has their version of the IAQ. I believe its a Tcon900. The Tcon 802, and 803, are just Honeywell Th8320's, and 8321's, relabeled with a few mods made for trane. But can't control 2 stages of gas furnace in a dual fuel.

I think the 900 is only for the communicating systems.

I'd want the IAQ so it will stage the backup instead of using the timer. Like in my house!

There are other stats that would do it from other brands.

I recently had that same furnace and heat pump installed. I have the Honeywell VisionPro IAQ thermostat and I like the features very much. Looks like a good choice. Get the outdoor temperature sensor as well.
