Here is my setup.
Old Thermostat Honeywell #T8411R
green wire --> G
blue wire --> C
red wire --> R
yellow wire --> Y jumper to W1
white wire --> W2
orange wire --> O
black and brown cable not used from wall
Current setup Honeywell #RTH7500D
green wire --> G
blue wire --> C
red wire --> R jumper to RC
yellow wire --> Y
white wire --> W2/Aux
orange wire --> O/B/W
RTH7500D Setup
o C o W2/Aux
o G o Y2/E
o Y o L
o O/B/W
o Rc
o R
Unit comes on, but no cold air is available. Is it something I did in the advanced setup? Did I install the wires in their correct slot? Any help would be greatly appreciated.
I have a Bryant multistage Heat pump #661CJ030-A outside.
Thanks for your help...

Everything is wired up correct.
Unit comes on, but no cold air is available.
Is both indoor and out door unit is running? Was it blowing cold air before you changed out the t-stat?

Post back of what you have the settings set to.

I'm not finding this number, either it's an older unit, or number is not the model #.
What's it the model # of the unit inside?

If you didn't turn off power to the indoor unit before replacing the stat the compressor may be locked out on thermal protection from short cycling.
