It can even sense when you’re near and adjust the temperature accordingly, ensuring that you always come home to a comfortable environment.

Smart home integration: Nest is compatible with various smart home devices, allowing for seamless integration and enhanced control over your home’s ecosystem. Whether it’s connecting with your smart lights, door locks, or security system, Nest can help create a truly connected and convenient home environment.

Remote access: With Nest, you gain the ability to control and monitor your thermostat from anywhere using your smartphone or tablet. Forgot to adjust the temperature before leaving for vacation? No problem. With Nest’s mobile app, you can easily make changes and ensure your home stays comfortable and energy-efficient, even when you’re miles away.

Learns and adapts: Nest is designed to learn from your behavior over time, adjusting the temperature based on your preferences. It builds a schedule that suits your needs and optimizes energy usage. Additionally, Nest’s built-in sensors can detect when you’re away and automatically switch to an energy-saving mode, further reducing energy waste.

Switch off the circuit breaker or remove the fuse to cut off the power supply.
For extra safety, you can place a piece of tape over the breaker or fuse to prevent someone from accidentally turning it on while you’re working.
Verify that the power is truly off by checking if your existing thermostat display is no longer illuminated.

It’s important to note that turning off the power is crucial to avoid electrical shock or damage to your HVAC system. Take your time at this step and ensure that the power is completely switched off before proceeding to the next step.

Step 2: Remove old thermostat

Now that you have turned off the power, it’s time to remove your old thermostat. Follow these steps:

Remove the thermostat cover by gently sliding it upwards or prying it off, depending on the design of your thermostat. Be careful not to damage any wires in the process.
Take note of the current wiring connections. You may want to take a picture or label the wires to ensure you can reconnect them correctly later.
Loosen the screws securing the thermostat base to the wall. Once the screws are loose, carefully lift the base away from the wall, exposing the wiring behind it.
Disconnect the wiring from the terminal screws. Depending on your thermostat, this may require unscrewing or simply pulling the wires out of their respective terminals.
Once the wiring is disconnected, remove the old thermostat base completely from the wall. Keep the screws and any other mounting hardware as you may need them for installing the Nest thermostat.

As you remove the old thermostat, be mindful of any fragile or delicate wires. Take your time to avoid damaging the wiring, as it will need to be properly connected to the Nest thermostat in the next steps. Keep the old thermostat and its base in a safe place in case you need them for reference or as backup.

Step 3: Label the wires

Before disconnecting the wiring from your old thermostat, it’s important to label each wire to ensure proper reconnection to the Nest thermostat later. Follow these steps to label the wires:

Once the old thermostat is removed from the wall, take a close look at the wires connected to the terminal screws.
Using the wire labels provided in your Nest thermostat package, affix a label to each wire based on its corresponding terminal. For example, label the wire connected to the “R” terminal as “R”, and so on.
If wire labels are not provided, you can use masking tape and a marker to manually label the wires.
Make sure the labels are clear and easy to read. This will prevent any confusion later when you connect the wires to the Nest thermostat.

Properly labeling the wires will save you time and frustration during the installation process. It will make it easier to identify which wire goes where when you are connecting them to the Nest thermostat base. Take your time to ensure that each wire is correctly labeled before proceeding to the next step.

Step 4: Mount the Nest base

With the wires labeled and ready, it’s time to mount the Nest base onto the wall. Follow these steps:

Choose an ideal location for the Nest base. It should be close to the existing wiring and in a central area of your home for optimal temperature sensing.
Place the Nest base against the wall, ensuring it is level. Use a level to double-check and adjust as needed.
Mark the location of the screw holes with a pencil. These holes will be used for securing the base to the wall.
If the existing screw holes do not align, or you are installing Nest onto a new wall, you may need to drill new holes with a drill and appropriate drill bit.
Once the screw holes are marked or drilled, insert the provided screws into the holes and tighten them, securing the Nest base firmly to the wall.

Make sure the Nest base is securely mounted to the wall before proceeding to the next step. A secure mount will ensure that the Nest thermostat remains stable and properly connected to the wiring.

Step 5: Connect the wires

Now that the Nest base is securely mounted, it’s time to connect the labeled wires from your old thermostat to the corresponding terminals on the Nest base. Follow these steps:

Take the labeled wires from Step 3 and match each wire to its respective terminal on the Nest base. The terminals will be labeled with letters or colors that correspond to the wire labels.
Loosen the terminal screws on the Nest base by using a screwdriver.
Insert each wire into its corresponding terminal, making sure the wires are properly seated.
Tighten the terminal screws securely, ensuring a proper connection between the wires and the Nest base.

It’s essential to connect each wire to the correct terminal to ensure the Nest thermostat functions properly. Double-check your wire labels and take your time to ensure that each wire is connected to the corresponding terminal on the Nest base.

If your old thermostat used a jumper wire between the Rh and Rc terminals, you can remove it as the Nest thermostat doesn’t require it.

Once all the wires are connected, you can proceed to the next step of installing the Nest display onto the base.

Step 6: Attach the Nest display

With the wiring complete, it’s time to attach the Nest display to the base. Follow these steps:

Take the Nest display and align the connectors on the back with the corresponding connectors on the Nest base.
Gently push the display onto the base until it clicks into place. The display should fit snugly and securely onto the base.
Once attached, the Nest display will power on and guide you through the initial setup process.

It’s important to ensure a proper connection between the Nest display and the base. Check that the display is securely attached and functioning correctly before moving on to the next step.

During the setup process, the Nest display will provide on-screen instructions to connect to your Wi-Fi network and complete the initial configuration. Follow the prompts on the display to set up your Nest thermostat according to your preferences.
