Nest Learning Thermostat 3rd Generation (Professional Version -Model # T3008US)

Nice product. Is it saving me money? I have no idea. Does it look fancy? Yes, yes it does. Easy to install but the second one I bought stopped holding a charge longer than 10 minutes. Support was amazing and quick to send a replacement unit. Working without issue now.

This unit was to replace one that was over 10 years old; with the internal battery having died. It was shipped FAST and new, not resold, Smart Thermostat. Worked perfectly out of the box with easy programming to link with my phone and computer apps. I absolutely LOVE the nest thermostat; making it SO easy to control the climate in the house.

Can’t go wrong with this thermostat. The only model we like to use. I am sure the newest is good as well, but at a much higher cost. This works very well, I can connect to it from my phone and change on the fly, and we have enjoyed them in multiple homes for a decent price.

Do NOT purchase this! I got one in June of 2024. It has already stopped working. My HVAC tech noted complete baseplate failure. It lasted just over one year. He swapped it out with the cheapest model he could find. All’s well now. Additionally - while it actually worked - I was prompted roughly once a month to enroll into a program which would allow my power company to control my temperatures. No thank you! I should only have needed to select that one once. Further, it initially kept reverting to “Eco” mode whenever I set my alarm to “Away.” The default settings were a complication, an irritation, an unintuitive nightmare.

I really liked Nest better before Google bought them. The software on the device was simple, elegant and worked the first time. Not so with Google - it takes at least two or three tries to get these Nest devices added to your existing account. I have no idea why it fails the first two, three and fourth times...and then magically it works - it's just a bad design and does not give you confidence in the device. The hardware installation was easy - but Google needs to update the package instructions...you guys stopped including the cool little screw driver that used to come with the Nest devices but you left it in the installation page as a part you include in the packaging. Once it's up and running, its great....but you need to be patient with it and not give up after the first couple of failed phone app equipment adds. Keep your phone is close proximity to the device - it attempts to add it that way - and sometimes it fails and have to keep trying....with each try it gets a bit further in the installation, finally getting on your wifi and getting it on the phone app. Overall - I loved Nest from the first day - you can see Googles hand here...and they messed up a very elegant and well designed device, but at the end of the day after a few try's it worked

Easy setup (read below if you have a two wire system without a C (common) wire), awesome interface, top notch quality, what else can I say? Love that I can control so many features from my laptop and smartphone. I also have three Nest Protect smoke and CO detectors which are monitored by the same app. Nest/Google hit not just a home run, but a grand slam out of the park with these two products.-------------------If you have a conventional two-wire system like me (Rc and W1), this is exactly what you need to get your smart thermostat working!When I removed my Honeywell digital thermostat (non wifi), it had only two leads connected: Rc and W1. Not knowing anything about the latest generation of wifi thermostats, I went ahead and ordered the Nest Pro Gen III thermostat. Upon setup, I ran into two codes; e73 and e74. Essentially, they had to do with no power going to the unit. my VIN and VOC were 2.50 so I dug around on the internet, which led me to this transformer.One lead went to C (24v common) and the other to Rh (see my photo of the interface's digital connection diagram). You may need to swap between Rc and Rh if you still have a error code readout. After plugging in the transformer, the VIN AND VOC read 34.17!!! Remember to plug this transformer into a surge protected outlet to prevent a possible damaged thermostat.

I have 2 at my cabin and just bought 2 more for my new home. My last home had a supposedly fancy version with the HVAC system and my HVAC installer said it would work better than the nest. I fell for it and spent 3 times the price on the matching thermostat. It was so much more difficult to use all the features and I wished for years I'd have stuck with a Nest. At my office, the local utility company was offering free Ecobee thermostats as part of their energy save program. I did that since it was free. Ecobee is also more difficult to use than Nest and if it wasn't free I'd have gone Nest too. When I moved here there was no question I'd go Nest again for both zones. There's no conflict with the Nests in 4 zones at multiple properties in one app. I will keep using Nest from now on. They simply work; my family understands how to use them without needing lessons; and hey, they look nice.

Very good price. Delivery as was described, right on time.
