If properly installed and set up, the Ecobee thermostat is one of the best smart thermostats you can get for your home. This thermostat has many features, from alerts or notifications to optimization of power and a lot more.
When it comes to this thermostat, one problem many people have is the installation process. Many people need help installing Ecobee when it comes to the C-wire. Some houses come to a C-wire setup, while others don’t. You might wonder if your Ecobee can function adequately without a C-wire. We will discuss the installation process and more in this article below.
While a C-wire is essential for installing a smart thermostat, it isn’t necessary when installing your Ecobee thermostat. One reason it is optional is that you can find a perfect and excellent alternative to the C-wire for your Ecobee thermostat connection.
One perfect alternative to not using a C-wire during the installation process of your Ecobee is a power extender kit. The power extender kit does the work and helps to replace your lack of a C-wire connection by giving you the necessary wiring outlets for your Ecobee thermostat to function optimally.
This device is very popular among households who use the Ecobee thermostat or other thermostats that require a c-wire connection. We shall discuss the installation process for the different Ecobee thermostats below.
How to Install Ecobee without a C-wire
As long as you have your power extender kit, installing your Ecobee without using or having a C-wire is pretty straightforward. Below is a guide on installing different Ecobee thermostats without a C-wire.
Step 1: Switch the Power off from the HVAC Equipment or the Control Board
Safety should always come first when wiring and installing devices in your home. To install the Ecobee thermostat, you must first turn off the HVAC system. The HVAC equipment controls your house’s heating and cooling systems/ wiring. Once you turn it off, you can do any type of wired installation in your heating or cooling system.
Sometimes, you might not be too sure of the switch that controls the HVAC equipment. When this happens, it is best just to turn off the power to the furnace. You will not be taking any chances when you do this. You can turn on the power when the installation is done.
Step 2: Remove the previous Thermostat and Check the Wiring
Once you are done switching off the power to your furnace or the HVAC system, simply remove the old thermostat on the wall; when you do this, take your time to check and observe where the wirings are connected on the backplate. Take a picture to wire your Ecobee according to the previous installation.
You should see wires of different colors connected to your Ecobee. You should see red, yellow, green and one red. These colors represent the R, G, Y, W, and possibly C-wires. Look at the ports the wires are connected to, as they will be connected the same way for your Ecobee thermostat.
Step 3: Connect your Power Extender kit to the Furnace and Do the Necessary Wiring
If you have done the above steps, the next thing to do is connect your extender kit to the furnace. Identify the thermostat wires as they are hooked to the furnace and connect them to your power extender. You will see the R, G, Y, W, and C- wire connections.
Unplug the wires from the furnace and connect them accordingly to the power extender kit. The ports on the extender kit are colored according to the wires that should be plugged into them. Plug the wires from the thermostat into the power extender kit and plug them into the corresponding terminals in the furnace. Ensure the wires are firmly connected inside the ports.
Once you do this, place the power extender kit inside the furnace and put the protective cover on the furnace.
Step 4. Install the Backplate and the Ecobee, and Power on
This is the last stage of installing your Ecobee 4 without a C-wire. You must ensure you install the backplate of the Ecobee 4 and ensure the wires are appropriately connected. There are labels on the ports of the backplate. Fix your wires into the ports according to the labels and ensure they are well connected.
Once you have installed your wires in the various ports, you can fix your Ecobee 4 on the backplate. Ensure the device keys into the backplate firmly. Check if there is any space or lose the connection between the Ecobee and the backplate, as it might hinder the device from working.
You can power on the HVAC system or your furnace once you install your Ecobee. Your Ecobee should power on immediately if the connections were done correctly.
Does the same Installation Process Apply to the Ecobee Lite and Ecobee 3?
Yes. Just as you can install the Ecobee 4 without a C-wire connection, you can also install the Ecobee lite and Ecobee 3 using the same process. There is no difference in the installation process. All you need to do is follow the steps in the previous subsection, and you are good to go.
While installing this device, you must pay enough attention to general safety precautions. Always turn off the HVAC system or the furnace before you begin any wired connection.
What Color is the C-wire in Ecobee Thermostat Wiring?
When it comes to c-wires in thermostats, many people often make a lot of assumptions. You must know that the c-wires in most thermostats are blue. While they may be other colors for other devices, the C-wires for thermostat installation are often blue. The blue wire controls the heat pump as it determines the level or amount of heat in the home.
Even though you can use your Ecobee without an obvious C-wire connection, you must know that the C- wire is essential for your thermostat or HVAC system. It is why power extender kits are used to replace the wire.
Conclusion
While a C-wire is essential for the proper function and setup of your Ecobee, there are always ways to go about it if there is no C-wire installation in your furnace. You can easily use a power extender kit with a power extender kit.
We have discussed the power extender kit installation for your Ecobee 4 and many more. Read through to get the steps on Ecobee installation wiring and much more.
