@CoolingWizard Finally got a chance to check the wiring inside the air handler. Not sure which to take but I took multiple shots. Hopefully this would clear up my wiring concerns. TIA.        

@CoolingWizard Not sure how to open the air handler but I got a picture of the board. Not sure if this helps.    

I haven’t got a chance yet. So what will I do with my upstairs wiring? I also have a nest learning hooked up. Do I change the white wire to W2 also?

I haven’t checked yet. I’m not sure how to open the wiring at the air handler. So what do I do with the upstairs thermostat? Do I put the white wire to W2 as well?

On my old thermostat, I have an emergency heat function. With nest, I couldn’t find that option.
