Only Stage 2 Cooling

[gearJammer063]

I have a Trane XL 18i Heat Pump with a Trane TAM 9 Air Handler. With the current wiring I only have Stage 2 cooling.. 

Where did I go wrong with the wiring? Not sure if the pic "Your System" is any help..  I don't and never will use Auxiliary Heat

Hi gearJammer063, 

Thanks for reaching out to us, and I'm sorry to hear about the situation. Let's sort this out.  

Please help us with a photo of how the wires are connected from your old thermostat and a photo of how the thermostat wires are connected to your HVAC control board.

I'll look forward to your response. 

Best,

Zoe

It appears to working correctly. The Nest uses Stage 2 cooling more then the old Trane Thermostat..
