Wiring problems - Trane and Honeywell

Guys - I need your expertise

I recently wired a Honeywell t8611M Thermostat to a Trane Airhandler./Furnca and Trane Heat Pump.

I used the following Thermostat Field Terminals
B - Heat - White
G- Green - Fan
R - Red - + 24
C - Blue - Common
Y1 - Yellow - Compr Activ
W3 - Black - Aux Heat
O - Orange - Cool


I used the following Trane Air Handler/Furnace TWE042C140B1 Field Terminals

R - Red - + 24
O - Orange - Cool
B - Blue - Common
W1/W2/W3 - Bridged
W1 - Heat - White
W2 - Black - Aux Heat
G- Green - Fan
T - Brown - Heat Pump Reset
Y1 - Yellow - Compr Activ

I used the following Trane Heat Pump TWR042C100B2 XE1000 Field Terminals


O - Orange - Cool
R - Red - + 24
B - Blue - Common
Y - Yellow - Compr Activ
T - Brown - Heat Pump Reset
W - White/Black - Heat

I'm confused re T at the Thermostat - there's no terminal. Also, I don't have LED's on the Thermostat Lighting up. I am considering bridging L onto R.

What do you guys think???


Thanks bd

Im not sure just what all you have there are if I can help. But first we tell people to forget a programmable tstat on a heat pump. After it sets back for a time and then turns up the temp it will turn on the strip heaters to help pick up the temp. So you lose what you just saved. This one they say has a lighter load demand in recovering from a heat set back. Ok on what you have there my books for the trane unit say note#6
T is N/A to programmable thermostat

The T8611m that I saw had batteries. Post back in the same post here some one might come up with what you have there

Trahe & Honeywell

Ed and HVAC4u,

Thanks for the input.

The furnace and heatpump are working....but the system doesn't shut off.

I am manually shutting the system off before I go to bed and then turning it back on in the morning.

Any Thoughts.
