New system going in tomorrow

[launn]

Well, the wife and I bit the bullet and went with a whole new system, which is being installed tomorrow. We went with a Trane xl15i and a XV95 furnace as well as the clean effects and a humidifier. The installer said they are putting in an 800 series thermostat, my question after reading around here is will I be better off going with an IAQ?

IMO...the 8000 will be fine but the IAQ is worth the upgrade...

[launn]

Will the trane thermostat be able to control the Variable speed fan for humidty control?

[beenthere]

No. Not the 800 series.

If it is dual fuel, by all means IAQ. For straight cool, then if you want the IAQ to control a humidifier or the dehumidify function, it would be nice.

Congratulations! You have the same basic system that I purchased last year (except for the Clean effects). I went with the TC803 Tstat. Make sure it is wired correctly. If It is difficult to have 6 wires going through the wall to the Tstat, then I would go with the IAQ where 3 wires to the tstat will be fine. Check your model numbers carefully of the equipment you are purchasing. I was under the impression I was buying a Trane E-Coil also but it turned out to be an ADP e-coil. (At least it was properly matched though). Also my e-coil is 1 ton larger I'm told for better efficiency. (My AC is 4 ton and the indoor e-coil is 5 ton).
Good Luck

P.S. When I purchased my system I did not know of the existence of the IAQ and had no understanding of HVAC whatsoever. If I could do it all over I'd likely go with the IAQ for better control although I have no issues with humidity in my home because I run on reduced blower speed all the time due to ESP issues. A nice side effect of slower blower speed is reduced humidity.

I think the one he was talking about using is a trane 803. Would I still be better off with the IAQ or will the 803 be able to control the humidifier and variable speed fan correctly?

[beenthere]

The 803 can't control the blower.
It can over cool to dehumidify though.

[launn]

So none of the trane ones will control the blower? I need to figure out what to tell him to get the correct one.
