No... Aux. is auxiliary heat strip. This is usually a white or black wire its up to the choice of the installers preferance. O or orange wire. is used to the reversing valve on a heat pump. If you do have a heat pump there is a programing section inside the Honeywell t-stat. which should say heat pump or straight cool, then another section that will ask if you want the reversing valve to energize in heat or cool. most Heat Pump brands energize in cool the exception is Rheem and Ruud they energize in heat.

Wiring instructions for Thermostat Honeywell with Carrier Package


Jumper R to Rc and hook hot wire from transformer to R usually red wire
O = Reversing valve probably white or orange If you get heat when calling for cool or Vice Versa then switch wire from O to the B terminal.
Y = Contactor usually yellow
G = Blower usally green
Jumper Aux to E need to go to unit and use the wire that goes to your Auxiliary or 2nd stage heat
L = Light if you have this terminal on your unit then hook it up.
C = Common from transformer usually black, if you have this terminal on your unit hook this wire up.
Make sure you go to your unit and only hook these wires up if they go to these locations.

I have a carrier air/heating unit with pump. It has 8 wires. Brown,blue, white, yellow, green, black, orange,and red. I'm trying to install honeywell thermostat. The wires from my unit are suppose to go...


Turn the power off to the air handler. Open the control cover. Write down what color wires go together at the wiring terminal. All 8 wires are probably not used.
Post the findings here.
In most cases,
E= brown-emergency heat
AUX=white-auxillary heat to supplement HP
Y= yellow-to compressor for heat or cool(hp)
G=green-indoor fan
O-orange-reversing valve on HP when energized in COOL
L=t-stat light(probably not used)
R=red-24v incoming power
B=black-reversing valve on HP when energized in HEAT
C=blue-common wire for 24v
Only one of the "O" or "B" will be used. Not both.

Blue (C) or sometimes (B) should be your common wire. Look at your schematics and locate common. Your Brown wire is (E) and is emergency heat, white wire (W) is Auxilary Heat, green wire (G) is fan relay, red wire (R) is power, yellow wire (Y) is Cooling and orange wire (O) is reversing valve.

Carrier Infinity Control Thermostat SYSTXCCUID01-B


Your old stat is wired for a traditional thermostat and not a communication stat like the new infinity you have. There is a module plug on the furnace board that will need to be connected to the new thermostat for it to work. The wires that are wired now are from a terminal strip inside the furnace. Please contact your local Carrier dealer. They may be able to get that harness for you
