Removing Your Existing Thermostat
Removing your existing thermostat is the first step when installing Google Nest without a C wire.
Depending on your current thermostat, you may need to remove the cover or unscrew the unit from the wall.
If youre unsure how to do this, you should refer to the instructions that came with your existing thermostat.
Once the thermostat is removed, you should be able to access the wiring and make sure that there is no C wire present.
If there is a C wire present, you will need to remove it before proceeding.
If there is no C wire present, you can move on to the next step.
Before you move on, make sure to note the setting of all the existing wiring and take a photo so you can refer to it later.
This will help you when it comes to connecting the adapters wires to the Nest.
Connecting the Adapter to the Existing Wiring
Connecting the adapter to the existing wiring is an important step in installing a Google Nest thermostat without a C wire.
Before beginning, it is important to turn off power to the HVAC system to avoid any potential shock or damage.
Once the power has been shut off, you can begin to connect the adapter to the existing wiring.
The first step is to locate the wire terminals on the existing thermostat.
Depending on the type of wiring, there may be several different terminals that need to be connected, including R, G, Y, and W.
Once these terminals have been identified, you can begin to connect the adapter.
The 24V AC adapter should have a small set of wires with labeled terminals.
Each of these terminals should be connected to the corresponding wire terminals on the existing thermostat.
It is important to ensure that the wiring is connected correctly, as any mistakes could cause the system to malfunction.
Once the adapter has been connected, you can attach the included wall plate.
This will secure the adapter to the wall and give you a place to mount the Nest base plate.
Finally, connect the adapters wires to the Nest base plate.
This will complete the wiring and allow the Nest to be powered.
With all of the wiring connected correctly, you can move on to the next step of configuring the Nest.
Mounting the Nest Base Plate
The next step after acquiring the necessary equipment is to mount the Nest base plate.
This is a critical step in the installation process, as the base plate is necessary to secure the Nest to the wall and provide the necessary connection points for the wires.
To begin, you will need to locate the existing thermostat mounting screws and remove them.
Then, with the existing wiring still connected, attach the Nest base plate to the wall using the same screws.
Make sure to securely attach the base plate, as it will need to support the weight of the Nest.
Once the base plate is in place, you can then connect the wires to the Nest.
Depending on the model of Nest you have, the wires may be color-coded, so make sure to connect the correct wires.
Finally, secure the Nest to the base plate with the screws included in the Nest packaging.
With the Nest base plate now in place, you can move on to the next step of connecting the adapter’s wires to the Nest.
Connecting the Adapter’s Wires to the Nest
Once you have acquired the necessary equipment, the next step in the process of installing Google Nest without a C wire is to connect the adapters wires to the Nest.
First, make sure that the AC adapter is unplugged from the power source.
Then, remove the Nest base plate from the wall and place it on a flat surface with the mounting screws facing up.
Next, identify the wires from the AC adapter and connect them to the appropriate terminals on the Nest base plate.
Generally, the red wire should be connected to the R terminal, the white wire should be connected to the W terminal, and the green wire should be connected to the G terminal.
If your AC adapter does not have a green wire, it should be connected to the C terminal.
When connecting the wires, make sure to use the provided screws to secure them in place.
Finally, plug the AC adapter into an outlet and make sure that the Nest base plate is properly connected to the power source.
With the adapters wires properly connected to the Nest, you are now ready to connect the Nest to the Wi-Fi network and configure the settings.
