I am replacing a Trane Baystat 239 thermostat with a Honeywell TH3210D1004 thermostat. The Trane thermostat is wired is follows:

Terminal Color of Wire

X2 Black
O Orange
G Green
Y Yellow
T Tan
R Red
W White - W is also jumpered to terminal U
F Not Used
B Blue


The wiring terminals on the Honeywell are as follows:

Terminal Description

C 24V Common
B Changeover valve energized in heating
R 24 VAC Power
L Sends output when set to emergency heat
O Changeover valve energized in cooling
G Fan Relay
Y Compressor Contactor
Aux Auxiliary Heat Relay
E Emergency Heat Relay

Can someone tell me which color wires to connect to each of the Honeywell terminals.
