There is nothing mentioned about Comfort R in the post. You only get one ramp cycle per cooling or heating call from Comfort R, after that it will change to 80% for first stage and increase to 100% for second stage depending on what the Tstat is calling for.

My heating contractor also gave me the same story about "the system was set correctly." I knew it wasn't.
checking the wiring to confirm it is wired exactly as the diagram in the OUTDOOR unit specifies is important for the XL16i. I have seen soo many times where an installer follows the wiring found in the air handler or thermostat instructions and those are NOT correct. Wiring this perticular unit for a standard two speed set up will result in improper air flow during low speed. That unit is not 50/100 for capacity, it is 75/100. If the unit is wired wrong then airflow doesn't meet capacity. Just curious but why is the IAQ thermostat installed? Do you introduce outdoor air or have a whole house filtration system? Love the VisionPro t-stat for all the installer settings you can config. Also where did they install your outdoor temperature sensor for lockout, hopefully its not at the bottom of your heat pump.
Set the compressor lock out to-10.

I'm pretty sure I can hear different stages of the fan speed (it's more of a switch from louder to quieter and vice versa).

I suppose you're right - with summers being so mild here I haven't experienced the unit running for so long last summer, but I'm pretty sure that it would have to had the temps gone so far up.

It starts to sound as if I really need to get a pro in to verify the wiring and dip switches settings mentioned earlier by hivacjack.
The question is how do I find a reliable pro?
I thought that the company that installed the system was one; they were authorized Trane dealer and even held the Trane Comfort Specialist designation and as it has already been determined, at least their lockout settings were incorrectly set (or at least not from the economical standpoint).
Also - how much a service call like that can cost? I suppose that if I had someone come in and determine that the original installer did the wiring incorrectly I could try to recover the cost of that visit PLUS get the original installer to fix the problem. On the other hand - I'm not sure I'd trust them with it...
For know, I'm closely monitoring the system and the energy usage and it seems to be working really well with the new settings (i.e. the house is warmer and I'm using less energy).
Thanks again for everyone's help and input!
