Knowing what each thermostat wire does can help in wiring up a new or replacement room thermostat. This data can also be helpful if thermostat wires have become mixed-up or improperly color-coded by allowing you to trace wires back to their control connection point.

We describe 25 different possible thermostat wires and their functions and connection point. What does each thermostat wire do or control and when are the various wires connected, taped-off, or connected to a labeled connector different than the wire's ID label?

In thermostat applications where a blue wire is used, the blue is usually a common circuit wire - e. In most thermostat wiring hookups the orange wire is used to control a reversing valve - switching from heating to cooling mode or vice-versa.

In most thermostat wiring hookups the white wire is used to switch heat on or off from the thermostat. In most thermostat wiring hookups the yellow wire is used to switch cooling on or off from the thermostat. Where comments indicate "or For example "R or V or VR" means that one of these three wire labels and connection terminals will be present and used for the control function described in the table. For most thermostat hookups you will not be using all of the wires and control functions listed here.

If not a Trane product O is typically not used. Check your thermostat wiring instructions. For example, for the Thermostat Model 3M this B wire is connected to thermostat terminal C for Trane products and for other brands B is taped off and not used.

The thermostat wiring on these systems can have very similar wiring properties. But what if you have a system that's a little different like a Heat Pump System, Then your thermostat is going to be wired a little different as well. First and foremost when you go to wire a thermostat, if you have any doubt of the type of HVAC system you have and are uncomfortable with wiring, then I highly recommend using a qualified HVAC service technician to complete your task.

This could save you a lot of unnecessary expenses in the long run. Now the thermostat circuits I will be covering will consist of the two scenarios I mentioned above. But an important issue here is that the diagrams and wiring color codes are going to be the most common standardize method. Always keep in mind that who ever wired your thermostat may not have followed these procedures and your color codes will not match the following examples. You will have to determine this before you start disconnecting any of your thermostat wiring.

I would highly recommend that you write down what color wire is going to which terminal. This way if your color codes don't match the normal code as the chart below indicates, you can still get a good idea of which wire should go where on your new thermostat.

If you're changing your old style thermostat to a programmable type, then most HVAC systems are compatible and will work just fine with a programmable unit.

But in the case of a Heat Pump system, You'll really have to do some research to verify that the programmable thermostat will work.

The following is a chart showing the most common terminals and their respective color codes and what that particular wire is used for in the circuit. Now most thermostat's will not have all of these termination points but the chart will help you determine color code and connection points for your particular unit. The diagram below shows how a basic 4-wire thermostat is connected as indicated by the color code chart above. The diagram shows how the wiring works. However your connections may seem a little different on the thermostat itself.

Just take a look at the picture below the diagram. Some thermostat units have a dedicated R terminal and it jumpers to the RC, RH or 4 terminals internally.

How do I wire and install my thermostat?

The W, Y and G terminals should be pretty straight forward on most all types of thermostat's. The following image is one of the most popular scenarios today.

This type thermostat is relatively easy to connect or change over to a programmable type thermostat. As mentioned in the previous paragraph, the only difference might be the lack of an "R" connection.

Now the following image here represents a heat pump system thermostat. These types systems are more involved because of the components associated with the system. Color codes may be different from one household to another, but generally the concept should be the same.

It's going to take a little research on the owners part to declare what is involved with your heat pump system and verify proper color codes. If you're changing a heat pump system thermostat to a programmable thermostat, be sure that the new thermostat is compatible with your style of system.

Once that is verified, the owners manual should be informative enough to complete the change over very easy. Be sure to check out my Thermostat Store for great bargains on all types of thermostats. I know it for it a fact. Watch this video for assistance on upgrading or installing a programmable thermostat.See the diagram below for what each wire controls on your system:. If you have a dual-fuel system, or are unsure, it is recommended that you contact a Professional HVAC Contractor to continue.

To protect your equipment, turn off the power at the breaker box or switch that controls your heating and cooling equipment. To make sure that your system is off, change the temperature on your existing thermostat so that your system starts heating or cooling. If you don't hear or feel the system turn on within 5 minutes, the power is off.

If you have a digital thermostat that has a blank display, you can skip this step. Next, remove your existing thermostat from the wall plate. Most thermostats pull directly off the wall. However, some lift from the bottom and lever off, and others have a locking tab. The next step is to take a picture of your wiring. When taking the picture, please make sure that the terminal markings are clearly visible.

If you see terminals labeled A B C, or 1 2 3 then your new thermostat may not be directly compatible, as your system requires a communicating thermostat.

If you see thick, black or red wires then you have a line voltage system. This type of wiring requires a line voltage thermostat and is not compatible with low voltage thermostats. If you see wires connected to terminals labeled G1,G2,G3, you will need a thermostat capable of controlling multiple fan speeds, none of our retail thermostats are compatible with this system type. What you should typically see is 18 - gauge solid core wire.

The most common configuration is five wires, however you could see as few as two, and as many as ten. Any wire that is present, but not connected to a terminal you will want to make a note of, but you will not label these wires.

Using the photos that you took, remove each wire one at time and label it. After you have removed and labeled all wires you can unscrew, remove the old thermostat wall plate and mount the new thermostat's wall plate.

If we recommend placing a wire in a terminal, do not move it to another terminal if we address it later in the guide. You will typically have one or two out of those three. If you just have one wire, regardless if it's labeled RC, it will go into the R terminal, and the jumper connecting terminals R and RC will be in place.

Some thermostats have a jumper switch, some have a metal staple, others may have a plug, and the jumper may also just be a wire connecting the two terminals. If you have more than one wire you have a wire labeled R, and another wire labeled Rc for example you can remove any jumpers between the R and Rc terminals, or push the switch to open the RC terminal so you can insert a wire.

Next, let's talk about the C, or common wire. If you have a Trane model thermostat, and have a wire labeled X or B refer to your thermostat manual.

In some cases, one of those wires may be your common. If you have a C wire, place it into the C terminal on your wall plate. A heat pump runs your compressor for both heating and cooling. Locate any unconnected wire labeled W or W1. Professional Contractor Support Call any of the product support numbers above and select the 'Contractor' option. How do I wire my thermostat? Last updated. Please follow the below guide for the basic wiring walkthrough: To protect your equipment, turn off the power at the breaker box or switch that controls your heating and cooling equipment.

Review your pictures. This type of wiring requires a line voltage thermostat and is not compatible with low voltage thermostats If you see wires connected to terminals labeled G1,G2,G3, you will need a thermostat capable of controlling multiple fan speeds, none of our retail thermostats are compatible with this system type.

Now, let's cover wiring configurations. Let's take a look at the G wire. This wire will go to the G terminal on your new thermostat.Free Wiring Diagram. Variety of braeburn thermostat wiring diagram. A wiring diagram is a simplified traditional pictorial representation of an electrical circuit.

It reveals the components of the circuit as streamlined forms, and also the power and also signal links in between the tools. A wiring diagram generally offers info regarding the family member placement as well as plan of devices and also terminals on the tools, in order to help in building or servicing the gadget.

An initial appearance at a circuit representation could be complex, but if you can review a train map, you can read schematics. The function is the exact same: getting from point A to direct B.

Literally, a circuit is the path that allows electrical power to flow. Voltage: Gauged in volts Vvoltage is the stress or pressure of electricity. This is generally provided by a battery such as a 9V battery or mains electricity, the outlets in your home run at V.

Outlets in various other countries operate at a different voltage, which is why you require a converter when taking a trip. Present: Existing is the flow of power, or even more specifically, the circulation of electrons.

Thermostat Wiring Explained

It is measured in Amperes Ampsand could just move when a voltage supply is linked. Resistance: Gauged in Ohms R or Oresistance specifies exactly how easily electrons can move through a material. Materials such as gold or copper, are called conductors, as they easily allow flow of motion reduced resistance. Plastic, wood, and also air are examples of insulators, preventing the movement of electrons high resistance. DC Straight Present. DC is a continual circulation of present in one instructions.

DC could move not just via conductors, but semi-conductors, insulators, or even a vacuum cleaner. AC Rotating Present. In Air Conditioner, the circulation of present regularly rotates in between two directions, commonly creating a sine wave.Wiring Diagram Sample.

Wiring diagrams help technicians to see how a controls are wired to the system.

Many people can understand and understand schematics referred to as label or line diagrams. This type of diagram is like going for a photograph with the parts and wires all connected up. A wiring diagram is a form of schematic which uses abstract pictorial symbols showing each of the interconnections of components in the system. Wiring diagrams include a couple of things: symbols that represent the components inside circuit, and lines that represent the connections between them.

Therefore, from wiring diagrams, you already know the relative location of the components and just how these are connected.

Wiring diagrams mainly shows the physical position of components and connections inside built circuit, but not necessarily in logic order.

It emphasizes for the layout with the wires. Schematics emphasize on how circuits work logically. To read a wiring diagram, is actually a program must know what fundamental elements are included in a wiring diagram, and which pictorial symbols are used to represent them. The common elements in a wiring diagram are ground, power, wire and connection, output devices, switches, resistors, logic gate, lights, etc. A line represents a wire.

Wires are utilized to connect the components together. All points over the wire are the same and connected. A black dot is used to point out the injunction of two lines. Main lines are represented by L1, L2, and so on. Usually different colors are used to distinguish the wires. There should be a legend about the wiring diagram to share with you what each color means. Usually circuits with more than two components have two basic varieties of connections: series and parallel. A series circuit is really a circuit where components are connected along one particular path, hence the current flows through one component to get through to the next one.

In a series circuit, voltages mount up for many components connected inside the circuit, and currents are similar through all components.

In a parallel circuit, each device is directly coupled to the power source, so each device receives a similar voltage. The current inside a parallel circuit flows along each parallel branch and re-combines once the branches meet again.

A good wiring diagram needs to be technically correct and clear to learn. Take care of everything. For example, the diagram should show the right direction in the negative and positive terminals of each one component. Use the proper symbols. Learn the meanings from the basic circuit symbols and select the proper ones to use.

Some from the symbols have really close look. You have to have the opportunity to share with the differences before applying them. Draw connecting wires as straight lines. Label components including resistors and capacitors making use of their values.

This information is designed to help you understand the function of the thermostat to assist you when installing a new one, or replacing or up-grading an old one. The thermostat is the control device that provides a simple user interface with the internal workings of your homes climate control system.

By the use of an adjustable set-point, the job of the thermostat is to turn on either the heating or cooling system to maintain the desired room temperature in the home, and to turn off the system when the desired temperature is achieved.

They connect to a two-wire thermostat generally a mechanical thermostat with a mercury filled ball connected to a coiled bi-metal strip. A basic two-wire thermostat can be compared to a simple single-pole switch that you will find throughout your home, only instead of you turning the switch on and off as required, a mechanical or electronic temperature controlled mechanism is the operator of the switch.

They usually operate at 24V ac power, and the source of this control power comes from a control transformer mounted either just outside, or inside the furnace body. The line voltage feeding the furnace to operate the fan blower motor is transformed down to a safer level of 24 volts the gas control valve needs 24 volts to openand after making a series loop through at least one safety device the most basic and mandatory one is an over-temperature shut downthe power goes up to the thermostat, and when the room temperature falls below the set-point, the contacts close completing the circuit to the gas valve allowing it to open, the main burner to ignite, and begin the heating cycle.

In this the most basic of heating systems, as the temperature of the heat exchanger rises, another contact is closed on the line voltage side of the equation, and the fan blower motor starts moving air through the heat exchanger and out through the ducting in the home.

If the fan fails to run for any reason, the heat exchanger will get too hot and the hi-limit temperature device will open the circuit to the gas valve, closing the valve and stopping the heat cycle.

This function allows you to circulate the air in the house by using the fan in the furnace without heating or cooling the air moving through the system.

The obvious down side of this is that if the battery goes dead the thermostat will no longer function. Climate control systems have evolved a great deal in the last several years with the evolution of electronic control.

This has made the units more efficient, with added safety features, and with this comes increased difficulty for the average home-owner to repair or replace any parts of the system that may break down and they will, but only when you really need it!

However, the terminals of the thermostats of today are still labeled the same, and provide the same functions as what we have discussed thus far. They just get a little more sophisticated so if you are pre-wiring a new home, check with the contractor providing the HVAC system as to what thermostat wiring is required. A new system may need as many as ten wires like a two-stage heat, two-stage cooling system, heat pump reversing valves, fan control, etc.

These additional terminals are not shown in this diagram. Now that you are armed with a basic understanding of the temperature control system in your home, you should now be able to identify what kind of system you have, and what type of functions you will need if replacing or up-grading your existing thermostat.

I hope this article helped with your question about thermostat wiring. Thanks for taking the time to read it! If you have any questions or comments on your furnace situation, feel free to add a comment below. I completely understand. Electricity can be downright scary. However, armed with the proper information you must have to work safely and completely, home owners like yourself CAN complete most simple home wiring projects.

Bookmark the permalink.So there are many more wires to connect up when installing a new or replacement t-stat. Gone are the two-wire days. In those times, all you needed was one wire from the furnace transformer. Plus, you had another to feed power to a gas valve or relay to turn the heat on and off.

So here, we show examples of Honeywell Thermostat Wiring Diagram 4 Wire for these higher wire count t-stats. Here, we focus on the 4 wire t-stats. Sometimes even for the above common color uses, the exact purpose of a wire is often not clear. Instead, take a picture or write down which lug on the old t-stat that each wire goes with.

For each wire, jot down its color. Plus, write the letter of the terminal on the old t-stat that it connects with. If the correct wire functions are still not clear, then trace the wires. You need to track the wires back to the HVAC unit itself. Then, find out which parts the various colors of wires attach to. Do not attempt to wire a t-stat yourself if you feel unsure with working with electricity. Further, wrong wiring can break the t-stat or furnace.

This can result in costly repairs. State-of-the-art HVAC systems these days, in addition to the original single stage heating provision. These often have a second stage heater. Plus, they also may have one or two cooling stages. Many also use another wire to turn on the compressor change over valve. This valve switches the unit between heating and cooling mode. There also may be a light L wire with a light connected to it on the t-stat.

This light shows heat pump status. Each of these newer functions must have its own wire from the t-stat to tell it when to turn on.

So, these color codes help keep all the wires straight. With them you can avoid matching a wire to the wrong t-tat terminal.
