I've always had a passion for creating a video about smart home setups, and today, I'm thrilled to finally have the chance to demonstrate how to install Google's latest Nest Learning Thermostat—a cutting-edge self-learning temperature control device.
To begin, let's head over to the main electrical box. Locate the thermostat circuit breaker, switch it off, and remove the batteries from your existing thermostat. Ensure the display is completely blank, indicating the power has been turned off. Now, gently shake the thermostat panel and pull it towards yourself to remove it. Before proceeding further, I recommend taking photos of the wires and their corresponding letter labels with your smartphone. This step will prove invaluable during the subsequent installation process.
Most modern thermostats have alphabet labels indicating the function of each terminal. In this guide, I used the label card that came with the Nest Thermostat to clarify the purpose of these letters. Once you've disconnected all the wires from its terminals, you can remove the base of the old thermostat.
Y signifies air conditioning. For larger homes with more thermostats, you'll encounter Y1 and Y2.
G represents the air outlet. G2 and G3 can serve as backup air outlets or adjust fan speed.
OB stands for the heat pump.
RC denotes the power supply for air conditioning.
W is for heating.
C indicates an uncharged neutral wire.
RH represents the power supply for heating.
With Google's thermostat base in place, insert the colored wires into the corresponding lettered terminals based on the photos you took earlier. If you can't discern the wire colors, remember to use the label stickers provided by Nest Thermostat to keep track before removing the wire from the previous step.
Now, it's time to configure the thermostat. If you plan to take advantage of the discounts offered by the local utility company that I'll discuss later, make sure to enable the Wi-Fi settings during the setup to meet their requirements.
As for the cost, Google's learning thermostat typically retails for around $250. As many electric companies across the United States encourage the adoption of smart home energy-saving devices, it's essential to check online to see if your local electric company offers any special discounts before purchasing. For instance, in my area, the San Francisco Bay Area, you can go to the PG&E website and enter information to determine your eligibility for the discount. Since it's my first installation, I was qualified for the promoted price of around $80, saving a substantial $170 from the full retail price. So, always double-check your eligibility for discounts before shopping for the smart home device—it can lead to significant savings.
