Hello,

I took my thermostat out to replace a new one, but then noticed that the new one needed batteries. I did the biggest mistake and forgot to relabel them and now I don't know how to hook up the wires!! :(

I have the following Wires (I know these wires are used because there are 2 other wires that are tucked (brown and orange):
Black
Blue
Green
Yellow
Red

The terminal (Trane T8011R) has these letters:
G F
B W
R X2
Y O

I had this combination and heat was coming out (wire color/terminal letter):
black/F
blue/B
Green/G
Yellow/Y
Red/R

Any clue would be really appreciated. I don't know how fast you guys reply, but I hope is fast cause I'm burning up here in Florida!! ;)

Did you get an answer?
