Product Overview

The Nest Learning Thermostat programs itself, then pays for itself. It learns from you and your home, programs itself automatically and helps save energy when you’re away—and you can control it using your phone, tablet or laptop. In independent studies, the Nest Thermostat saved an average of 10–12% on heating bills and 15% on cooling bills. Based on typical energy costs, that means it pays for itself in under two years.
  • Auto-Schedule: no more confusing programming; Nest thermostat learns the temperatures you like and programs itself
  • Auto-Away: automatically turns itself down when you’re away to avoid heating or cooling an empty home
  • Nest Leaf: appears when you turn the Nest thermostat to a temperature that's energy efficient and guides you in the right direction
  • Energy History: see when heating and cooling were on and what affected your energy use
  • Remote Control: connect Nest thermostat to Wi-Fi to change the temperature from your smartphone, tablet or laptop
  • Auto-Tune: finds ways to automatically lower your energy bill while keeping you comfortable, enabling two Nest features: Rush Hour Rewards and Seasonal Savings
  • System Match: turns on specific features for forced air, heat pump or radiant to help you save energy and stay comfortable
  • Sunblock: in many homes the Nest thermostat is in direct sunlight, causing it to warm up; Nest automatically adapts to direct sunlight to read and set the right temperature

How manny mpbs do you need to operate the nest?

Asked by Sc July 10, 2017

Obviously faster is better. That said, you connect to your thermostat through their dedicated server, so all you need is a connection. Speed isn't really an issue.

Does this thermostat require a 'C' wire? Can the power source just be the battery?

Asked by bean June 1, 2017

Best explained by NEST. https://nest.com/support/article/When-Nest-needs-a-common-C-wire


Asked by Phil May 18, 2017

Multiple thermostats will be needed for multiple floors. Operation can be done from a smartphone.

2nd Gen vs 3rd

Asked by Brad March 3, 2017

Will nest work on an RV

Asked by Rick December 9, 2016

Yes it can. A Nest Thermostat can be wired with numerous wired combinations. And if your RV has internet when mobile, it can be controlled remotely, or always controlled directly.

Can this be used with the nest cam

Asked by crash June 14, 2016

Yes this can, and can be operated from cell phones, I-Pads etc.

There are 4 wires connecting to me current device and there are 2 AAs batteries as a power source. If I connect my Nest

Asked by DADDYofTHREE May 8, 2016

It will need to be powered by your system. You should have a blue wire. Connect it to "C" and it should work. You can also contact Nest. They have good customer service.

does this product have the passcode lock feature?

Asked by loycee April 8, 2016

That is an option you can set up

Don’t Do It
I have a combination furnace and AC unit. Once it gets cold, something in the AC shuts off to protect the AC unit. This then stops charging the Nest thermostat and it just goes dead, shutting down your furnace. Last year I called and talked with customer support to fix it. This year on Christmas I woke up with a house full of people and it was 56 degrees in our house. I called support and we switched wires; it worked for a day. Now I’ve been on hold for 40 minutes trying to talk woth a tech. This has NEVER been a problem with any other thermostat. I guess I can spend $200 to have a common wire put it, but seriously?! Spending $200 for a thermostat that stops working, no thanks. I guess I can spend money on a other one and throw this one away, just like I did the $200 when I bought it.

not quite as easy to install for our set up as i was hoping but we got it up and running. some of the features are unclear - i.e. we have a humidifier and i thought it was able to connect to NEST but we couldn't make that work. Setting up the NEST once connected was easy....figuring out how to utilize the app most efficiently is next. Over all very happy w the purchase.

Easy to Install. Seems to work great. I haven't utilized all of it's function, due to personal preferences, but love the remote access and ease of programming.

I installed a 3rd Gen Nest Thermostat downstairs a couple of months ago. It works great and installation was a breeze. I decided to add a 2nd Gen upstairs--it's not working properly (fan runs for a minute, then stops). It indicates that it's at the desired temperature, but it's not. It's going back

I love the Nest thermostat. Easy to install, easy to use. I was given one in my last house by a utility provider and liked it so much I bought 2 for each zone in my new house. I think I might have liked the thinner style and colors in the newest one but I liked the price for the 2nd generation.
