Are you planning to install a Google Nest Thermostat but not sure about the wiring diagram? This article will guide you through the steps of wiring your Nest Thermostat properly.
Understanding the Google Nest Thermostat
The Nest Thermostat is a smart thermostat that learns your preferred temperature settings and adjusts accordingly. You can control it using the Nest app or voice assistants like Google Assistant or Alexa.
Before we start with the wiring diagram, it’s important to understand some of the key features of the Google Nest Thermostat:
- Compatibility: The Nest Thermostat is compatible with most HVAC systems, including forced-air systems, heat pumps, radiant systems, and more.
- Power: The Nest Thermostat requires a constant power source, either from your HVAC system’s wiring or through a connected C-wire.
- Wiring: The Nest Thermostat uses a standard wiring system that includes Rc, Rh, C, Y, W, and G wires.
Wiring Diagram for Nest Thermostat
The wiring diagram for a Nest Thermostat is fairly straightforward. Here’s a step-by-step guide to wiring your Nest Thermostat:
Step 1: Turn off the Power
Before you start working on your HVAC system, it’s crucial to turn off the power. You can do this by turning off the breaker that powers your HVAC system.
Step 2: Remove the Old Thermostat
Next, you need to remove the old thermostat from the wall. This involves unscrewing it from the wall and disconnecting the wires from the terminals.
Step 3: Identify the Wires
Once you’ve removed the old thermostat, you need to identify the wires that were connected to it. You should see Rc, Rh, C, Y, W, and G wires.
Step 4: Connect the Wires to the Nest Base Plate
Now it’s time to connect the wires to the Nest Base Plate. The Nest Base Plate has six terminals labeled Rc, Rh, C, Y, W, and G.
Here’s how you should connect the wires:
- Connect the Rc wire to the Rc terminal
- Connect the Rh wire to the Rh terminal
- Connect the C wire to the C terminal
- Connect the Y wire to the Y terminal
- Connect the W wire to the W terminal
- Connect the G wire to the G terminal
Step 5: Mount the Nest Thermostat
Once you’ve connected the wires to the Nest Base Plate, it’s time to mount the Nest Thermostat on the wall. Simply align the Nest Base Plate to the wall and tighten the screws. Then, attach the Nest Thermostat to the Base Plate.
Step 6: Turn on the Power
Finally, it’s time to turn on the power. Turn on the breaker that powers your HVAC system and wait for the Nest Thermostat to power up. Once it’s powered up, you can start using the Nest app to control your thermostat.
