How to install the Google Nest Learning Thermostat

[@NathanHarrison7]

Leave it to Google to, 1) Write and film perfect instructions and 2) build a level bubble into the device. Genius.

[@YouDontNeedMyName1]

And back lit bubble level at that. (If you do it live.)

This is a god damned revelation of an instructional video and combined with the online chat support where you can send pictures of your existing wiring etc this should get an academy award. Bravo google. Bravo. Amazing instructions.

[@bhouldsworth]

It seems the online chat support where you can send them a picture has gone - I'm trying to find that and it just keeps taking me to the standard support page where you figure things out for yourself, or to the community.

[@curtsmith8612]

If you just have a Red wire, hook it to either Rh or Rc, doesn't mater... Unlike most thermostats, the Nest Learning Thermostat does not require a jumper wire between Rh and Rc. Nest knows that if you've got heating and cooling, and just one R wire, the power source is shared between them. ... Nest Thermostat connectors are built so that only one wire can be inserted per connector.

[@orlandojohnson5742]

This is all well & good …..for gas heat applications!!!! I jus left a house today with a HEAT PUMP & I suspect the installer didn’t configure Nest for the proper system! You need to show wiring & set up for both gas furnace/ac… and heat pump with auxiliary/emergency!!! Now I have to go back to this house & check wiring at Nest & configure for heat pump! The Installer is the main person to blame so far!!!! I’m glad you have info that helps with install & removal! I don’t wanna tear it up taking it off the wall! Wish me luck!

[@nak4651]

Couldn't be easier...my a/c-furnace thermostat had a 5th brown wire that connected to the "C" terminal....worked like a charm. I believe that some systems have a brown/blue wire that connects to the "C" terminal as mine did. Many thanks to your video for making the installation and setup a piece of cake.

@@joelauro5152 you should still always turn the power off. Not so much to protect you from low voltages (even if it was 120 you would only feel a tingle) but actually to prevent yourself from shorting out the small fuses and electronics that are inevitably part of an AC system👍🏽

[@learnit4499]

my thermostat has only blue, yellow and red. there are no white and green wires. what should i do? Thanks

[@juicymullet4468]

I just want to throw this in here for a heads up. When I installed mine, the "W" cord (the white one) was in the "W" slot on my old thermostat. When I inserted it into the "W" slot into the NEST, only the heat came on. If you're having this problem, take the "W" cord and insert it into the "O/B" slot. The video doesn't tell you this, so it might not apply to everyone, but that's what got mine working. Other than that, set up really is a breeze.

[@marcinkossakowski4737]

Do you have a heat pump? That would explain O/B... W is used for conventional air conditioning.

[@juicymullet4468]

marcin kossakowski Yes, I have a heat pump, and you're right that that's the reason for the O/B. They should mention this in the video IMO.

[@CatoNoise]

I think this fixed my problem, thanks so much!

I am having this problem. Weekday do I do with the wire that is already on the o/b spot, as ith was in the original set up

Do I have to turn it off at the breaker box, or can I just turn the furnace off at the off switch on the side of the cabinet? What's this about a "C" connection or the Nest won't work?

[@wyattlacey1]

Install was pretty easy, works to spec (in the short run.) The hardest part is having to matching the 20 year old paint, which I am going to call 'Navajo dirt floor' for demonstration purposes. I sure hope that this thing lasts.

[@TheGalacticCrusader]

Pro tip: cut out a inch x inch square and take it to a paint shop. They use a computer to match the color. Be sure the sample location is a good representation of the color since sun/grease/dust might make it look different than you want. Get a sample size of paint which often is free and then test it out. Mine matched perfectly

[@hitabo]

I bought one of these, and the first month it was in place my bill soared from 450 dollars to more than 1250 dollars. I called, and they said, "that happens sometimes." They told me how to turn off the "smart" features of the thermostat, and I paid my insane electric bill. I later found out my kids were coming home from school and cranking the ac down in the heat of summer when nobody was home, so that's what it started doing. Can't blame the company for that, but oh my goodness was that a sad discovery. It doesn't seem to shut off reliably when the temperature is reached (it gets way chilly) as well. Can't say I recommend this product because now it's just a pretty thermostat. There needs to be a warning on the box.

[@ntbullies]

Set notifications. If temperature drops above or below where you want it, you'll get a notification

[@betsyk22]

There is also a limit you can enter and a code required to override the range. Helpful for situations like this or for AirBnb's etc

I moved into this house last June with the Nest installed already by the previous owner. The unit has been working fine until last night. The Internet has been disconnected. I checked the Nest and it indicated that the batter power is too low -- 3.716V. And I check the Equipment has this configuration: W1-Y1-G-Rc. I pulled out the Nest, and there is no C wire. Should I run a C wire to keep the Next charged up all the time as suggested by some?

[@johnspence2168]

I went through it with a friend and he helped me make it work. I had to connect a C wire. In the end I added 2 wires to my wiring setup. But it functions. Personally as I'm not a fan of it. I just assumed it would be better than a regular programmable thermostat but it's not really the case. In my opinion the learning is a gimmick seems almost useless. Setup was overly complicated. Only a single person can have the app connected. Setting up a time schedule is 50x more complicated than it should be. After a couple of days I'd rate it 3 out of 5. If I had bought it at Costco or another store I visit regularly I would return it

[@nickhickson8738]

My existing Honeywell thermostat is connected to the Central Heating pump only and controls that. When the temperature in our hall, where it's situated, drops then the thermostat detects that and turns on the pump and that fires up the boiler and hence the radiators get hot again. Simples! Why complicate matters so with a swanky device and anyway what it 'Fan' ? I don't have that.

Can you add those threshold settings like in Ecobee? In cold areas, furnaces might short cycle every 15mins like four times per hour and waste energy. If we can set the heat to run a minimal 30 mins and the start to run threshold to be 2F, it would actually save more energy.

My system has 5 wires, but still no power available. Does it mean the c-wire is not connected to furnace correctly or is it something else?

Does every person in the house have to install both apps and create an account so they can control the thermostat too?
