One of the easiest ways to control your utility costs at home is to install a smart thermostat. This one piece of equipment allows you to automatically set temperature preferences so that you’re not heating or cooling empty space. You can also adjust the needs of your home through an app connected to a smartphone or tablet.
If you recently purchased a smart thermostat and want to complete a DIY installation, then these are the steps you’ll want to follow.
Steps to Follow When Installing a Smart Thermostat
- Turn off your HVAC system.
You must turn off your existing HVAC system at the breaker panel. Most homeowners will need to manage multiple switches. Taking this action will prevent you from accidentally shorting our electrical components, and it also keeps you safe.
- Remove the faceplate of the thermostat.
You must remove the faceplate of your old thermostat to install the new one. This step allows you to access the backplate and low-voltage wiring that’s present for your system. You might need to remove a hidden screw. Take a picture of the installation so that you know how to connect the new system before disconnecting the wires.
- Remove the backplate.
Now you need to remove the wires from the backplate. You might need to back out a few small screws that hold the wire in place. Then take out the screws that affix the unit to the wall.
- Add a common wire.
If your system already has a common wire, then you can skip this step.
If it does not, then your smart thermostat likely needs one. You may need to hire an electrician for this job. Some products come with a C-wire adapter that allows you to move on with the installation.
- Prepare your wall for the new backplate.
Use the backplate of the smart thermostat to mark on the wall where the new screws will affix the unit. Then drill holes in the marks. You may need to use wall anchors to secure the unit.
- Reconnect all of your wires.
Once you have the backplate securely attached to the wall, you can connect the thermostat wires once again. Use the photo that you took to place each wire at its corresponding terminal. You must match the wiring correctly to ensure that the new thermostat will work correctly.
- Install the new faceplate.
Once the wiring is in place and the backplate is secure, you can snap the faceplate of your new thermostat in place. Don’t force it if you experience difficulties with this step since that could mean a wire is in the way.
After you complete the final step, you can go back to the breaker panel to restore power to the system. Then you’ll need to complete the setup process for your unit so that it can provide your home with the intelligent temperature settings that you want. The process differs for each make and model, so be sure to refer to your owner’s manual with any questions you might have.
