Thermostat wiring terminals and colors


R - The R terminal is the power for the thermostat. This comes from the transformer usually located in the blower section for split systems but you may find the transformer in the condensing unit. For this reason, it is a good idea to kill the power at the condensing unit and the blower section before changing or working on the wiring at the thermostat. If you have a package unit then the transformer is in the package unit.
Red for the R terminal.

RC - The RC terminal is designated for the power for cooling. Some HVAC systems use two transformers. A transformer for cooling and a transformer for heating. In this case the power from the transformer in the blower section would go to the thermostat terminal. It should be noted that a jumper can be installed between RC and RH for a heating and cooling system equipped with a single transformer.
Red for RC terminal.

RH - The RH terminal is designated for the power for heating. See RC above for an explanation. It should be noted that a jumper can be installed between RC and RH for a heating and cooling system equipped with a single transformer.

Y - This is the terminal for cooling or air conditioning and goes to the compressor relay. Typically a thermostat wire pull is made to the air handler on split systems and then this wire is spliced for the separate wire pull which is made to the condenser. Some manufacturers put a terminal board strip near the control board in the air handler so a splice is not needed.
Yellow for Y Terminal.

Y2 - This is the thermostat terminal for cooling second stage if your system is so equipped. Many systems only have a single compressor but if you have two compressors which should only operate off of one thermostat then you need the Y2 thermostat terminal for second stage cooling.
*The most common color I've seen used for this terminal and wire designation is light blue but this varies and is completely up to the installer what color to use. Most installers use the color coding as noted but be aware that some do not use the thermostat color coding.

W - This is the thermostat terminal for heating. This wire should go directly to the heating source whether it be a gas or oil furnace, electric furnace, or boiler,
White for W Terminal.

W2 - This is the thermostat terminal used for second stage heat. There are gas furnaces with low fire and high fire and some depend on control from a two-stage heating thermostat with a W2 terminal. Heat Pumps use staging for auxiliary heat and need a W2 terminal.
*The most common color I've seen used for this terminal and wire designation is brown but this varies and is completely up to the installer what color to use.

G - This is the thermostat terminal used for the fan relay to energize the indoor blower fan. On a split system the blower fan is in the blower section while with a package unit the blower fan is in the outdoor package unit.

Green for G Terminal.

C - This is the thermostat terminal which originates from the transformer and is necessary to complete the 24 volts power circuit in the thermostat but only if the thermostat consumes electricity for power. Many digital thermostats require 24 volts for power so the common wire is necessary.
C stands for common and there is no universal color used for this terminal although black is the most common color I've seen.

O or B - These thermostat terminals are for heat pumps and the B thermostat terminal is used on for Rheem or Ruud and any manufacturer that energizes the reversing valve in heating mode for the heat pump. Most other manufacturers of heat pumps will utilize the reversing valve for cooling and the O thermostat terminal will be utilized for this purpose. This wire goes to outside heat pump condenser where the reversing valve is located.

Orange for O and Dark Blue for B depending on the installer of the heat pump and the manufacturer. If you have a Trane, Carrier, Goodman, Lennox, Ducane, Heil, Fedders, Amana, Janitrol, or any other manufacturer other than Rheem or Ruud you will be utilizing the orange wire for reversing valve. Rheem and Ruud will usually utilize the blue wire for reversing valve.

E - This thermostat terminal is for heat pumps and stands for Emergency Heating. If for whatever reason the heat pump condenser fails and it is necessary to run the heat there is an option on heat pump thermostats for emergency heating. Basically this simply utilizes the back-up heat source many heat pumps have to heat the home without sending a signal to the condenser to run for heat.

E - There is no universal color used for this thermostat terminal designation but this should be wired directly to the heating relay or the E terminal on a terminal strip board in the air handler or package unit if you have a heat pump package unit.

X or Aux - This thermostat terminal is for back-up on a heat pump and allows for auxiliary heating from the back-up heat source usually located in the air handler.

X or Aux - There is no universal color used for this thermostat terminal designation but this should be wired directly to the heating relay or the Aux terminal on a terminal strip board in the air handler or package unit if you have a heat pump package unit.

S1 & S2 or Outdoor 1 and Outdoor 2 - Some thermostats have this terminal and it used for an outdoor temperature sensor. The wire uses for this should be special shielded wire and completely separate form the other thermostat wires.

Hey, I purchased your Honeywell RTH2510 Thermostat, but I didn't even think to label the wires when I took the old thermostat off. Upon installation of the new Thermostat (2510) the Air Conditioning...


The connections that you really need to reference would be at the air handler itself. That would tell you which wires go outside to the heat pump and which wires go to the air handler. I can however give you some basics that may help.

Heat Pump Wiring
Terminals/Colors/Function
R- Red- 24v power supply. (Usually a jumper between RC/RH)
G- Green- Fan
W- White- Heat (Sometimes W1-W2, first or second stage heat)
Y- Yellow- Cooling (Same applies as above i.e. Y1-Y2)
C- Common (Most people use blue unless it is used for B terminal and sometimes cooling on older 4 wire systems.
B/O- Reversing Valve for heat pump. Either powered heating or powered cooling, depending on system installed.
Aux- Also used for heat.

Note: Considering that the installer had their own way to run all wires, use different wires, connections, etc. This is just a reference to common wiring in the field.

How the most common system is hooked up:
Thermostat:
Red wire goes to R terminal
Yellow wire goes to Y1 or Y2 terminal
Green wire goes to G terminal
White wire usually goes to W1 or W2 terminal
Orange or Black wire goes to B/O terminal
Brown wire usually goes to Aux terminal
Blue wire goes to C terminal, unless its being used as stated above.

This is without using a fossil fuel kit or zone control board.

Where do they go from the thermostat?
Red
goes to the air handler transformer or board and goes outside to heat pump to power low voltage controls.
Yellow wire goes straight outside to Y terminals on heat pump unless going to a board inside first.
Green goes to the air handler fan relay.
Common goes to the air handler and outside to heat pump.
Black or Orange will go outside to heat pump terminals for reversing valve.
White usually goes outside to heat pump,and inside to air handler. Will explain reason further down.
Brown will go to the air handler to the heat relay for the emergency heat.

On a call for heat, with a powered cooling system (more common).
The R, Y, and G terminals energize, sending a signal to start the blower and pull in the contactor outside. Note that the Y terminal is usually cooling, but since this is a powered cooling system, the reversing valve is not energized, causing the system to run in heat mode. If you have powered heating, the reversing valve terminal will energize also. Depending on thermostat, if you set the temp substantially higher than room temp, it may kick on the emergency/aux heat to quickly raise the room temp. On a call for emergency/aux heat, the R, G, and E/Aux terminals are energized, turning on the electric/gas heat instead of the heat pump. This comes in handy since the heat pump can only pull so much heat from outside before its not enough to properly warm the house, usually around 30 degrees outside temp. If you are running the heat pump and the system goes into "defrost", the outside unit will send a signal back to the air handler, through the white wire I mentioned earlier, to tell the emergency/aux heat to come on while it is in defrost mode, providing heat whenever needed.

Again, this is just a reference guide to some basic wiring, but hopefully it will tell you where the problem is or at the least, give you a good start. There are variables in which things can change the wiring like a zoning system or fossil fuel kit. Even then, you should be able to get pretty close. Hope this helps and Happy Holidays!

You should have more wires than just two, and you should also only have 1 power wire at the thermostat. Red is usually the power, white is usually for heat, unless it's the wires going to the outside unit. On a normal system, those two wires are the power and common going to the contactor. Heat pumps have more. However, you will not actually need a common terminal, all commons are just grounded to the units housing, therefore your common is nothing more than a ground wire. Hope this helps!

Have 3 ton elec a/c and heat - heat is on and air is blowing cold, unit is new (15 mos) home 1350 sf - breakers are OK, filter is clean - what can you tell me?


If its not a heat pump- check the white wire connection on the thermostat. If it IS a heat pump, check the blue wire connection on the thermostat. Both of these wires control the heat in their respective systems.

A/C does not cool like it used to, unit runs


sound like your system is under sized. for every 400 sq ft of living space you should have a ton of ac or 12000 btus. also check and see if your attic fan is working. any drafty windows or doors. your supply temp should be at least 20 deg colder then your return temp. also check your filter should be changed every three months this will help with air flow.

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.

Installing 1 1/2 ton Weatherking Heatpump and ADP WAK351807P2 air handler 1 /1/2 with 7.5KW back up heat kit. Can't seem to get the thermostat hooked correctly. I understand the Weather King product...


O energizes the reversing valve when the thermostat is set for COOL. B energizes the reversing valve when the thermostat is set for HEAT.
The O/B is usually a orange or black wire.
You can't hurt anything if you choose O or B incorrectly. Hook one of them up and run the unit. If set for COOL and the unit runs cool inside it is correct. If set for COOL and the unit runs warm inside it is not correct.
If the inside temp is opposite from your setting change the wire to the other terminal.
Remember to disconnect power from the air handler when changing thermostat wires.
The defrost control board on the outside unit should be marked correctly for O or B.
Your thermostat may have a slide switch rather than a separate terminal.

Heat strip install


What color wire is connected to the "Y" terminal on the thermostat.
If the unit you are connecting is a heat pump A/C unit the orange wire is for the heating mode. Normally the "Y" terminal on the thermostat. "R" terminal on the thermostat is the power to the thermostat, "W" terminal is for heating, "Y" is for cooling, and "G" terminal is for fan operation. At the condensing unit for cooling the brown and yellow wires would normally be for the cooling.
