Understanding the C Wire and Ecobee Compatibility
If you’re considering installing an Ecobee smart thermostat, it’s important to understand what a C wire is and why it matters.
The C wire, or common wire, is used to provide a continuous flow of power to your thermostat, which is essential for proper functioning.
The Ecobee thermostat is compatible with systems that have a C wire, but it is also designed to work without one.
However, if your current system does not have a C wire, it’s important to determine if it’s compatible with the Ecobee thermostat.

The table above shows the Ecobee wiring diagram and the systems that are compatible without a C wire.
If your current system is not compatible, you may need to run a new C wire or use an alternative method, such as a power extender kit.
It’s important to note that while the Ecobee thermostat is designed to work without a C wire, it may cause issues such as short cycling or damage to your HVAC system if not installed properly.
Therefore, it’s crucial to follow the installation guide carefully to ensure a safe and effective installation.
Gathering the Necessary Tools and Equipment
Before beginning the installation process, you will need to gather the necessary tools and equipment.
Having these items on hand will make the installation process smoother and more efficient.
Ensure that you have the following:
- Wire strippers
- Voltage tester
- Ecobee smart thermostat
- Mounting plate
- Screws and anchors for mounting plate
- Pen and paper for taking notes
These tools and equipment will be used throughout the installation process, from removing the old thermostat to mounting and setting up the Ecobee thermostat.
Make sure to have them readily available before beginning the installation process.
Now that you have the necessary tools and equipment, you are ready to move on to the next step of the Ecobee smart thermostat installation process.
Powering the Ecobee Without a C Wire
Now that you have gathered the necessary tools and equipment, it’s time to power the Ecobee thermostat without a C wire.
This may seem daunting, but don’t worry – we’ve got you covered.
First, turn off power to your HVAC system by switching off the circuit breaker.
This is crucial for safety reasons. Next, remove the cover of your thermostat to access the wires.
Locate the G wire, which controls the fan, and the Rc wire, which powers the cooling system.
These two wires will be used to power your Ecobee thermostat.
Insert the G wire into the C terminal on the Ecobee base plate and tighten the screw to secure it in place.
Next, insert the Rc wire into the Rc terminal on the Ecobee base plate and tighten the screw to secure it.
It’s important to note that the Rc and Rh terminals on the Ecobee are jumpered by default.
This means that if you only have an Rh wire, you can use it to power the thermostat as well.
Simply insert the Rh wire into the Rc terminal and tighten the screw.
If you are still unsure or uncomfortable with this wiring method, another option is to use a power extender kit (PEK).
This kit can be purchased separately and provides power to your Ecobee thermostat without the need for a C wire.
Once you have wired the Ecobee properly, snap the base plate onto the wall and proceed to the next steps.
Connecting the Ecobee Thermostat
With the Ecobee base plate installed, it’s time to connect the thermostat to your home’s Wi-Fi network.
Follow the on-screen instructions to connect to your network and create an Ecobee account.
Once connected, your Ecobee thermostat will automatically download any available software updates.
This process may take a few minutes, so be patient.
With your Ecobee up and running, it’s time to remove your old thermostat and wire the new one.
We’ll cover this process in the next section.
Removing the Old Thermostat
Before installing your Ecobee thermostat, you need to remove your old thermostat.
If this is your first time replacing a thermostat, do not worry as it is a fairly straightforward process.
To get started:
- Turn off the power to your old thermostat by switching off the circuit breaker.
- Next, remove the thermostat cover using a screwdriver.
- Once you have removed the cover, you should see the wires connected to the thermostat. Take a picture of the wiring to ensure you know where each wire was connected.
- Using a voltage tester, test the wires to confirm that the power is off before proceeding with the removal.
- Using a screwdriver, unscrew the mounting plate and remove it from the wall. Again, make sure you have a clear picture of the existing holes, so you know where to install the new mounting plate for your Ecobee thermostat.
Once you have removed the old thermostat mounting plate, you are ready to move on to the next step of the installation process.
Wiring the Ecobee Thermostat
Now that you have gathered the necessary tools and equipment, you can begin wiring the Ecobee thermostat without a C wire.
Follow these step-by-step instructions:
- First, turn off the power supply to your HVAC system. You can do this by turning off the circuit breaker or removing the fuse.
- Remove the cover of your old thermostat and take note of the wires connected to it. Different HVAC systems may have different colored wires, but the most common ones are:
If your old thermostat does not have a C wire connection, it may be connected to the G wire instead.
- Disconnect the wires from your old thermostat and remove the mounting plate from the wall.
- Using the wiring diagram provided in the Ecobee installation guide, connect the wires to the corresponding terminals on the Ecobee thermostat.
- If you are using the G wire as a C wire, connect it to the C terminal on the Ecobee thermostat.
- Once all wires are securely connected, attach the Ecobee thermostat to the mounting plate and turn on the power supply to your HVAC system.
- Test the thermostat to ensure it is properly connected and functioning correctly. Follow the testing and troubleshooting instructions provided in the Ecobee installation guide.
