View Full Version : Trane XL19i ...any problems with these model numbers?

AIR HANDLER TWE040E13FB
HEAT PUMP 2TWZ9036B1000A
HEAT STRIP BAYHTR1410BRKB
I am thinking that I will go with the humidistat TCONT803.
My big question though is, is this Air Handler model number a good choice for a 3.0 ton unit?

Good match, I would use the Vision Pro IAQ not the Trane branded models. The IAQ allows for true dehumidification on demand with the variable speed air handler and will stage the backup heat. The 803/8321 only overcools the place if humidity is high. Actually with 10 kw, probably no staging though. But the other feature is worth it.

That match should get you max SEER and a btu rating of 37,800 in cool mode. So yes the match is ideal.

One suggestion, because you will notice when the contactors 'pull in', suggest that the contractor put cork tape behind each contactor to dampen the sound.
Also, VisionPro IAQ also less labor intensive to install, you will not have to run new wire. The contractor may push you towards the TCONT stat due to Trane's rebate requirements. Simply ask that he install the VPIAQ and check that he installed the TCONT803...paperwork, what a hassle.

I hate to pile on, but the VP IAQ would be a much better choice. As stated below it will allow you to control A/C dehumidification on low or high speed, plus it will allow you easier upgrades in the future to whole house dehumidication, humidification or ventilation in the future, all from the same control. It will also be much easier for the contractor to upgrade to these in the future b/c all the wiring is done in the equipment room.
Part number for VP IAQ (in case installer doesn't know)
