@jclalabama

Try this

Brown - X to C

Blue - B to OB

White - E to W (set as Aux Heat) (Jumper to W2 not needed)

Yellow - Y to Y

Green - G to G

Red - R to R

Is the black wire connected to anything? I can't tell.

I also can't see how each wire is connected in the last picture, which shows the Thermostat cables connected to the air handler cables.

Do you have the model number for the air handler in the attic?

@Patrick_Caezza I hooked it up as you said and ended up wiring the white (e) to the black (w2) to get the heat going

Hello jclalabama,

Happy to hear that! I appreciate the gesture. It looks like we can consider this one complete, so I will be locking this in 24 hours if we won't hear back from you again. Feel free to start a new thread and we'll be happy to help.

Thanks for your help, @Patrick_Caezza.

All the best,
Zoe
