Questions & Answers

Q:How do I change the batterie
by|Mar 12, 2024
1 Answer
Answer This Question

A:  Hi there, Dexter. Thanks for asking about Nest Temperature Sensor. If you need to replace the battery, simply insert a coin into the slot on the back of your sensor and turn to unscrew the battery cover. The device uses a CR2 Lithium battery which is already included with your device and is commonly available at a local store. If you have additional inquiries, please don't hesitate to contact us on our Google Nest Help page here: https://support.google.com/googlenest/gethelp

    Q:Question regarding the manual fan option. I have a G wire on my nest base and I can get the fan to operate but I have a variable speed fan in my air handler. Can the nest thermostat go to a lower speed for the fan when there is no call for heat/cool

    Answer This Question

    A:  Hi there, Shane. Thanks for your inquiry about the Nest Learning Thermostat. Variable speed fans are compatible with Nest thermostats, but the fans will only operate at a single speed. Nest thermostats are compatible with most fans and systems that use standard 24-volt wiring.

        Q:Does this thermostat automatically switch between the heat and air to keep a constant temperature or do you have to manually switch modes?
        by|Dec 27, 2023
        1 Answer
        Answer This Question

        A:  Hi there, BigJoe55. Thanks for the inquiry about the Nest Learning Thermostat. This device has a feature called “Auto-Schedule” to help you create and adjust the temperature automatically based on your preferences. Also, with five available thermostat temperature modes, the device can keep your home within the temperature range you’ve set, and automatically switch your system between heating and/or cooling as needed to meet any scheduled temperatures or a temperature you’ve manually selected.

            Wasnt as easy as they said to connect. Had to pull the battery and let it sit for 5 min before retrying in which it fanally connected. Distance for communication is really good. Definitely recommend if you have a larger spread out floor plan.
            Good distance, good buy.

            no smarts, just a schedule.
            In short their app nor the product is smart. The rigid adherence to the schedule is the largest issue. If I change the temp 5m ago, I don't still want the thermostat to move to the sleeping temp. Why is the review length so short?

              Great Thermostat
              Easy install and set up. Works great. However, it does require a common wire.

                WIFI Chip Failure!
                Do your research before buying this product! You have been warned. WIFI chip went bad in mine in less than 6 months. Their customer service is non-existent. Chat only, no phone support. Warranty says 2-years, but they will not honor it. Horrible cheap product. Features are awesome when they work, the problem is they are not reliable. Search online for Nest WIFI chip failure. Then make your decision. I recommend buying a different brand altogether.

                  I really like this product. Installation was a breeze and it gave my room a nice upgraded look. It wakes up when you walk by it, which is pretty cool, as I sometime use it as a night light. Overall great product.

                    Great product. Had to return this though because there was a used one in the factory sealed box. Great staff at HD. No hassle returning it but they were sold out of this color so I got another one.
