SOURCE: I have a carrier air/heating unit with pump. It

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.

SOURCE: 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.

Testimonial: "everything is working like a charm now. Initially it was not running but after 5 minutes or so the Fan came up and it is working fine. Thanks"

SOURCE: Replaced Bryant T-stat model TSTATBBNB001 with Honeywell t-stat

Hello,You forgot to wire the O terminal w1 witch is the reversing valve.It is important to check if old stat is using O or B in witch case B terminal=w1 leaving O unused.

Installed a rth6350 now no power


The RTH6350 is a battery-powered thermostat. Did you correctly install the AA batteries? Press down and pull the battery holder away from the thermostat on the right hand side. Try new batteries. Did you remember to secure the C wire with a wire nut and push it back into the wall. It should not be connected to the thermostat.

If you connected the C wire, you may have damaged the thermostat by providing too much current. Honeywell has the documentation for the RTH6350 on the product page: http://yourhome.honeywell.com/home/Products/Thermostats/5-2-Day-Programmable/RTH6350D.htm . The installation guide is here: https://customer.honeywell.com/request.cfm?form=69-2416ES . See page 23 and subsequent pages for the wiring diagrams.

I hope this helps.

I replaced an old mercury T-stat (York with model number 2TH11704024) installed a new T-stat (RTH6350). The wires that I I have are O (orange), G (green), Y (yellow), T (gray but not used in new T-stat),...


Did you shut the power off to the air handler/furnace...... before you installed the new thermostat??? You may have shorted out the transformer or blown the transformer fuse...... If you try to put the Fan switch on the stat to Fan ON does the fan come on ..... if it does the transformer is OK.. On the new thermostat did you program it to tell it that you had a heat pump system ???? Looks like you had it wired right. Here is a pdf manual for a RTH6350 http://customer.honeywell.com/techlit/pdf/PackedLit/69-2416ES.pdf

Its on page 13 Advance setup for tell the new stat that you have a heat pump....There is also a Honey well Hot line on page 2 Hope this helps.

Trying to hook up Honeywell RTH6350 thermostat. When turned on cool out air blows out. We only have a green, red, yellow and white wire from the old unit. Are we missing some wires? we have a heat pump.


Your Thermostat should wire as Red to Rc/Rh (if Rc/Rh are not connected you need to put a jumper between them; White to W; Green to G; and Yellow to Y on your thermostat. These will be the only wire connections that you need to connect from the unit to the thermostat. However, if your thermostat is not battery operated and is programmable then you will have to run on wire form the transformer in the units C to the Bl on your thermostat.

Your original wiring configuration seems to indicate that you have an air conditioner (not heat pump) and either a gas or electric furnace. If this is the case you may need a different thermostat for your application.

Three wires not marked for new Thermostat!


You will need to go to the heating system and see what color wires are hooked to that. Typically the black and white wires will be used unless they used another color due to a bad wire. Hook the colored wires to the R or RH terminal on the thermostat and the other wire to the W terminal. You can also try taking the wires you have and one by one twisting them together and have a second person inform you when the heating system turns on. Take those two wires and hook them to the terminals I mentioned above.

Installing Honeywell RTH7000 - I have too many wires!


check to see if the B terminal is on the new t-stat if connect to it , but this terminal refers to heat pumps and is normally use to energize the reversing valve on the outside unit and not used on ac units , but normally the tag O/B is the same terminal on therostats
