Step 10: Tagging Your Wires.

With the faceplate now gone you can see in what locations these wires go. You can remove each wire and tag each wire with its name i.e. RC, RH Y1 and so on. Or you could simply take a picture of the wires and use it later when installing the ecobee. If you have a jumper cable like I do in from RC to RH ignore this as your ecobee will not need a jumper. Simply focus on the wires coming from the wall.

Step 11: Disconnecting the Wires From Your Old Unit

Disconnect each wire from your old unit. At the end the only wires attached the unit should be the jumper cables if you had any.

Step 12: Removing the Backplate

Unscrew the 2 supporting screws of the back plate with your Phillips screwdriver.

Now that you have removed the 2 screws. Pull the wires through the hole and remove the old backplate.

Step 14: Installing New Backplate

Find the new backplate and place it up to where the old plate used to be. If you have no damage you can use this plate as is. Mark the wall where your 2 new holes are going to be.

Step 15: Drilling the Holes for the New Backplate

Use a power drill to make the 2 new holes for you.

Step 20: Ensuring Backplate Is Level

Locate the built in level installed in the bottom of your ecobee.

Step 21: Leveling Your New Backplate

Ensure the bubble is in between the 2 lines. Once you verify this you can screw in the screws till they are secured.

Step 22: Incorrect Way to Wire Backplate.

When securing the wires do not place them in the holes facing you like pictured above.

Step 23: Correct Way to Wire Back Plate.

Secure the wires to the holes on the side of each label as pictured above. This is the part where you will need to reference the picture you took earlier to ensure you place the correct wires in the correct letters.

    I have only seen briefly the Nest Thermostat and was curious in the past as to what the installation process required. Ecobee is a competitor for sure. Smart Home devices are really taking off and advancing. It will be interesting to see where they go next in the future. That's awesome how you're able to utilize Alexa and other voice assistants for temperature control too!

    Is this what they are using with Alexa or the other "smart" home devices?

    Yes, you can use this with Alexa. I personally use Siri as I have an iPhone and Apple TV. I can simply ask Siri to turn on the AC and set to a temperature.

    Thanks I really like it. I specially like being able to control my A/C from any where in the house with my iPhone.
