Onto The Installation

Let us guide you through each step.

Keep in mind that the process will vary depending on your setup. Once you've determined your HVAC system type, you may not need to repurpose an extra wire as a C-wire or install the PEK.

Removing your old thermostat backplate

Once your HVAC system is powered off, gently remove your existing thermostat’s faceplate to check your compatibility.

How to determine your HVAC system type

Determine your HVAC system type by checking if you have one or two sets of terminal labels on your old thermostat's backplate.

How to install your thermostat with a C-wire

If you have a C-wire, it will power your ecobee. You won't need the PEK included in the box.

How to repurpose an extra wire as a C-wire

If you have an extra wire that isn’t connected to any terminal on your thermostat, you can use it as a C-wire.

If your ecobee doesn’t turn on, please try these steps.

Check that all wires are properly inserted into the terminal blocks at the thermostat. Tug on the wires to ensure they are not loose.

Make sure your HVAC cover panel is closed. Some systems will not turn on if the cover panel has not been closed properly.

If you have only one R wire (either R, Rc, or Rh), make sure it’s inserted into the Rc terminal.

If you installed the Power Extender Kit, make sure you inserted the wires into the correct terminals.
