I am replacing my old thermostat with a new Honeywell RTH7400. Here are the wire terminals from my old one:
G
Y
T
R
O
W
B
X2

and the terminals on the new one are:
C
G
Y
O/B
Rc
R
Aux
E
L

I have all the wires in except for the one off the old off the old thermostat that was connected to the "T" terminal. I have looked through the manual but I can't find this in there. Can someone tell me where to connect this? It would be very much appreciated!

P.S. I for some reason can't access the honeywell site, it says I need to disable my cookies, but when I do it still won't let me, so links to there won't work.

Thanks in advance!

The "T" is a outdoor thermister, tape it off and don't connect it to anything, Good luck, Mike
