23 and 21 degree delta tee. Not bad...

I suspect that you are looking at the diagnostic LED instead of the cfm LED.
The CFM LED is pictured in post 6. It is by the dip switches.

I think we are good.

Oh, OK,

6 blinks on 1, 600 cfm
12 on 2, 1200 cfm

As you predicted

Nice of you to say, but I would not have done any of this without your guidance.

Do you think I am going to be able to get the Comfort-R dehumidification setup with the XL900? I read in a couple places that I might need some sort of relay (?) to make it work? Other have said that I should look at the trans XL824 or the Honeywell IAQ which is the one you said you are familiar with.

Your cfm output is very low for stage 1 because you have a 5 ton Trane furnace with a three ton 2 step scroll compressor.

The thermostat is not the cause of this limitation.
That furnace would not give you dehumidification with a matching 2 step scroll compressor .

The BK terminal is still tied up if you have a matched system if it is a 2 step scroll.
The BK terminal is available if you get the two compressor condenser.

OK, so you think I am at my peak performance with this system, there is nothing more I should do until I am ready to replace major components?

I would be fine with that.

Yes,you are correct. I donít think that we can add dehumification with that condenser.
