First, it’s important to make sure that you really don’t have a C wire (more on that shortly). It’s also important to understand what a C wire is, so you know why it’s necessary to have one. What is a “C” Wire?Today, many thermostats come with Wi-Fi capabilities. This means the thermostat is able to connect to your Wi-Fi so you can manage the temperature through an app on your smartphone or tablet. One of the most difficult tasks when setting up these thermostats is setting up the Wi-Fi. However, it is not impossible!First, let’s understand what a c wire actually meansA “C” wire is also referred to as a common wire.

The common wire is the low-voltage power wire that WiFi thermostats require in order for their advanced features to work. Unfortunately, many older homes do not have a C wire installed because old thermostat model simply didn’t require one.You see, old model thermostats were simple devices. They didn’t need a continuous power supply.

But often have backlit displays and WiFi connectivity, which requires a steady stream of power.Chances are, you will not have a C-wire, which is an AC common wire. This is because many homes still have older thermostats that were not made to have Wi-Fi capabilities, therefore they did not require the installation of a C-wire.Today’s new thermostats have backlights, geolocation abilities, and Wi-Fi, and in order to have these qualities, you need a C-wire. Also, many buyers wonder if they can simply install their and still use its advanced features. You can’t – unfortunately.

How to Check for a “C” WireThe simplest and easiest way to check for a common wire is to look at your thermostat. Detach the thermostat from the wall, and take a look at the wires that are connecting to it.There should be a terminal labeled “C.” If a wire is connected to this terminal, you’re good to go. You can just install your new thermostat as normal.If you don’t see a wire connected to the “C” terminal, don’t panic – you may still have one.

Sometimes, the common wire is hidden in the wall behind the thermostat.To find out if you have a hidden “C” wire, check your furnace. If you find a common wire here, there’s a good chance that it’s just hiding in the wall. Step 2Power off the heating, ventilation and air conditioner system before starting with your installation. Do this by turning off the master switch on your circuit box. This box is usually found in your basement, attic, closet, or garage.Step 3Ensure your system is shut off by turning on your air and feeling your vents for any air movement.

You should not feel anything.Step 4Remove the old thermostat cover from the wall. You shouldn’t need any tools for this.

It should just need to be popped off or unclipped from the base.Warning: If your thermostat’s back plate has a lot of indicators that say L1 L2, warning high voltage, or 110 VAC, 120 VAC or 240 VAC, then sadly you will not be compatible for this.Step 5Quickly, snap a picture of the wires that are located on the back of your old thermostat. You will need this for future reference.Step 6Since we already established you do not have a C-wire, you will need to use the Power Extender Kit (the PEK). Here is the one recommend from Ecobee.The PEK requires certain wires for your system in order to work:.

4 Wires: y/y1, R, G, W/w1. 3 Wires: R, y/y1, and GStep 7Take the power extender kit, tools, your smartphone, and wire labels, and take them over to your HVAC system (often found in your basement or attic).Step 8Open the HVAC cover to its control board and take a picture of the wires that are connected to the control board. You might need these for reference.Step 9Label the R, Y, G and W wires for assistance.

Next, disconnect the R, Y, G and W wires from the control board, and re-connect them to the matching grey terminal blocks located on the Power Extender Kit. Step 14Press the thermostat back into its back plate and click it shut. Then turn your HVAC system back on!

Important Things to Consider During the InstallationFirst and foremost, make sure you have the right tools! Below is a tool checklist to help ensure you are prepared before you start:. Drill. Small flathead screwdriver. Phillips screwdriver. Hammer. Pencil.

Skip the guessing game and make the process move quicker by knowing your wires.Lastly, double check your package and make sure you have everything you need. Use this check list to ensure you have everything before you start:. New thermostat. Backplate.

Power extender kit. Trim plate. Install guide. Drywall plugs. Third Option:Run a “C” wire from your furnace to your thermostat. Now, you can hire a pro to do this (which is what we recommend), or you can do it yourself. How to Add A C-Wire to FurnaceThe number one thing to keep in mind is to make sure your breaker for the furnace is off before you begin with installation!To connect a C-wire to your furnace, you first need to make sure that your furnace comes equipped with a C terminal.

If your furnace does not have a C terminal, you can add a 24V transformer to the furnace, which will make the furnace compatible with a C-wire connection.To add a C-wire to your furnace, follow these steps:. Turn off the breaker for the furnace. Remove the access panel and locate the wires that connect to the thermostat. Disconnect the thermostat wire from the G terminal. Connect the C-wire to the C terminal. Note: If you have both central heat and air, then you’ll need to make a jumper using an 18 AWG wire. This DIY-friendly alternative and inexpensive option will bring you the Wi-Fi capabilities to your new thermostat.

What is in the box?. Venstar Add-a-Wire device. Additional wires. Installation manual. Electrical capsThe tools you will need:. Phillips screwdrivers. Electrical tape.

Needle nose pliers. Drill/drill bit. 2 wire nuts (included)The Venstar Add-a-Wire adapter is much cheaper and much easier than running completely new HVAC wiring. If you don’t have the time, money or experience to re-wire your system yourself, we highly recommend this to those with no C-wires.

Solved the C wire concern by moving the the fan wire G to C at the furnace. The G wire only controlles the fan without heat in manuale fan mode. If you do this trick you won’t be able to manually turn the fan on. If you never run just the fan by itself with no heat it will work to move the G to C at the furnance. If you do like to just run the fan manually with no heat then do not do this trick. At the thermostate use the G for C. But first you will need to acces your Furnace.

Disable power to your furnace and pop the cover off. Look for a row of screws labeled R, C, W, W2, G, Y/Y2,Move G wire to the C wire screw at the furnance.

The white wire is the heat wire and the fan will run automaticaly with the heat without a G wire. I have an Ecobee 3 that came with a PEK, My current thermostat has 4 wires, red, white, green and blue, on the one side of the PEK, I hooked the 4 wires up, R, W, G and the blue I put in the hole marked Y. For the 5 wires coming out from the other side, I hooked them to the furnace control panel, R to R, C to C, G to G, W to W and Y to Y.

On the thermostat mounting there are two sides that can be connected, one one side from top to bottom, it is labeled Rc,G,Y1,W1(AUX),O/B. On the other side from top to bottom it is labeled Rh,C,Y2,W2(AUX2),ACC+,ACC-, Where do I hook up the 4 wires to on the back of the thermostat to?
