Appreciate you going through all the settings as I just received my nest, and installed a brand new system in my house. I would advise against setting temperatures at extreme ranges when home/away. For example, if you normally heat around 68, I would only allow it drop about 3-4 degrees or so during away or at night. Allowing your home to cool down to 57 and then having to work to increase 10+ degrees in the winter causes hvac systems to work harder. I'd just keep ranges moderate. :)
@@jolkraeremeark6949 I've always used 20 degrees as a guideline. Why? Because as long as you're not dropping below freezing temperature in the winter, or melting your wax seals or other melty things under your toilets, and you have no animals to worry with, it really doesn't matter one flip.
Fantastic video. Not "filler" running on with opinions, and boring jokes and over-analysis, blah...blah. Just very concise and perfect information. Thanks so very much!!
Thank you thank you thank you my wife was about to kill me we moved into a new house and the schedule was set to turn the temperature way down at night and we were fighting with it and I finally found your TH-cam video and you literally saved my life
How to fix a OFFLINE problem ? We live in Germany and our Florida Winter house has 2 Nest thermostats. Our FL property manager says it is working properly in FL house, but for us in Germany shows on our Nest App that it it offline, but our wifi in FL house is OK as all our cameras in FL house is working fine. Please help us to fiz the offline issue in our side in Germany, can you ?
Very informative. I purchased a condo and the realtor didn't say a word about it having a nest thermostat so I'm having to look at youtube to' learn how to use it. Can the previous owner of the condo still have access to the thermostat from their phone?
Extremely helpful video. Thanks. Is there a way to adjust the fan speed when heating. My Nest runs at normal speed then kicks into high speed (very loud) for some reason. Thanks
Will it control furnace blower ON/OFF? My humidifier is mist kind and requires heat and blower working together with humidifier. My humidifier also requires furnace blower to work a couple minutes after humidifier switches off automatically to distribute all the moisture collected in the duct. If blower stops the same time with mist humidifier moisture still will sit inside plenum and makes it rust. Will this Humidifier Control have this setting so furnace blower work few minutes after humidifier switched off??
Do you have any install/usage info for the Nest door sensor? We have a property that we rent in Hawaii and it has a large lanai door that opens fully and we don't want the AC on when the door is open. Can you help with this application?
Idk if this will help me but it's worth a shot. I've a nest thermostat like the 1 in the video but I'm confused about it. It's downstairs and set to 77° thing is it cools every part of the house but 1 room. And the weird thing on that is when it is set to 74° I feel the air perfectly in that room but downstairs they get to cold. Any idea of what I'm suppose to do so the room doesn't feel like a sauna or swet box
I feel like you glazed over the fan. When I turn my phone on, the screen turns blue for cooling and I don't want cooling. I just want the fan to blow but it makes me set a temp. Any thoughts?
At present what if I have a wireless thermostat connected to a controller that is mounted on the furnace plenum, but want to install the Nest thermostat that needs to be wired? Can it be located near the furnace?
I don’t have that Active Sensor option on my Nest Learning Thermostat, is it be it’s 6 years old? But they update over wifi so shouldn’t this provide OS updates?
Hi glad I found this! I thought If I reset it, I won’t be able to use it in my apartment again..... it may sound like a silly question, just wanted to reiterate, just so I’m clear. If I reset it, I would still be able to have my heat and AC?? This belongs to an apartment. I want to be able to use the app but it says that it’s connected to an account already. I just don’t want to do something that I can’t undo.
The Home/Away Assist function in the Google Nest App, the Presence Sensing function and the Homs/Away Automations in the Google Home App failed miserably to automatically switch in and out of ECO mode. I found no solutions in those functions. I did find a solution in the Automations of the Google Home app. First I turned off all the Home/Away Functions in the Nest app, all the Presence Sensing functions and Home/Away routines in the Home app. Then in Automations in the Home App, I set up two new routines. These routines use precise location info just like a naviagtion app would and were set up to mimic what the Home/Away and Presense Sensing functions are supposed to do. My Arrive Home routine is set at 150 meters from home to change my thermostat to Heat - Cool mode. My Leave Home routine is set at 500 meters from home to change my thermostat to ECO mode. I tested and it worked exactly like I have wanted Home/Away to work all along.
Thanks for this video. However, the Safety Temperature "Cool" setting is set at 96 degrees and CANNOT be lowered. My brand new expensive unit is completely worthless in the desert. If a house is allowed to reach 96 degrees as a "safety" measure, someone at Google is missing common sense or is actually an employee of a power company. Numerous posts to the Nest website confirms this is a factory setting and that nothing the user can do will change it. I was therefore curious that you skipped over the "Cool to:" setting on your video.
I'm not sure if it's the app or actually the thermostat, but I have my heat set 72 degrees and the cool set to 80 degrees, for some reason it decides to reset itself to 71 degrees for heat and 81 degrees for cool. It's not in ECO mode it just seems to arbitrarily do this. any ideas why. Update on this post I'm pretty sure it's the app on my phone that was causing this, I would advise people after setting up all your peripheral Nest devices with the app on your phone to uninstall it, my thermostat seems to be doing what I have it set to now. Do not go to the Google Nest forums either any topic for legitimate concerns that users have Google immediately closes the discussion.
I installed the system and I can see all the wires connected correctly in the setup screen, but nothing happens (No heat or AC)? Any idea what could be wrong?
How do I make the Nest shut all the way off at a certain time. I want it to go completely off everyday at 7:00pm and come back on at 11:00 am the next day. How do I set that? 🤔
david stuart 1 second ago i find these things incredibly insensitive - mine set to deg c - it will let the room temp wander up around 1.5c and down 1.5c before bothering to pass on info to boiler! - this results in huge lingering temp swings of c 4 c typically taking u from sweating to shivering every few hrs - what resolution do these things have?? - even the display only has an accuracy of 1/2 degrees - my $5 digital thermometers display to 0.1 and have shown to be accurate to 0.2, so whats with the Nest?
Set up my 3rd Gen Nest today and having a problem. 2 wire system - no fan wire. Added the C wire plug in accessory also. Had to put both power wires in the Rh slot the other in the W1 slot. I set the Nest to 22C. The display is not red, just black with white letters. The fan and furnace is not turning off and the temp has risen to 28C. Thoughts anyone?
Has anyone had to remove the black back plate that can mount on a nest? I received a 3rd gen nest thermostat, but it has a black back plate that won't come off so I can mount it using the typical back plate. PLEASE HELP!! this is so frustrating!!! Thank you. :)
thanks. easy to understand. i got to this page by accident. i was looking for info on how to fix something i just saw for the first time, after having the Nest for about a year and a half. All of a sudden, i was trying adjust the temperature, it's early September, over 100 degrees outside in Los Angeles and i wanted to turn down my thermostat to get the AC to come on. I only ever use the app on my iphone to adjust the temperature instead of the wall thermostat. i tapped on the down arrow to lower the temperature and at first it acted normal, 76, 75, but then, it jumped right from 75 to 73, so i tapped the up button, i wanted it at 74, but it jumped up to that 76 or even 77, it was making big jumps. ?? i tried to do it more carefully and at about that time, i noticed that on the white background just under the blue temperature number, 75 or whatever it was, there was a small word in gray text which said DELAYED. ? I was able to get it to the right temperature. i opened it and closed it and quit the app a braa nd restarted it and it still said DELAYED. i googled it. the links all said it was an easy fix but i had to install a C wire or obtain some appliance with brand name and install that. It said that the Next recharges its Lithium battery off of the HVAC or off the furnace, not from power lines. it said that could be a problem for some people. i never had this before and i don't know any of those things. i just wanted to know whether there was some way to fix it by rebooting the whole system. Or do i have to hire somebody? none of those answers said if there was an easier way besides installing a new wire to fix it .so i tried you tube and i enjoyed your video. Meanwhile the word DELAYED went away. So glad. as it turns out, an HVAC tech checked out my system a few months ago and said i had a carbon monoxide leak so he turned off my furnace. so i was afraid that this was why my Nest was saying Delayed since it can't recharge its battery off the furnace. i'm really glad it came back on , i need to have another opinion on whether i need a new HVAC or if whatever's wrong can be repaired, he emailed me photos, he said something was rusted and it might be cracked, i don't remember right now, i have a detailed email. anyway, it's good to have an online instruction source for my Nest now, thanks !!

I'm curious. If I have a sensor inside of my solar space heating collector, is there a setting that will turn on the "fan only" that reacts to temperature and not time?
Not sure. The thermostat is essentially a switch. So if you want to run the fan, when it reaches 65 degrees you could connect the R and W and it would turn on whatever you had connected when the temperature reached the setpoint you had indicated. I don't know the specifics of what inputs and outputs you have with your system but where's there's a will there's a way.
Nice overview, but I am looking for someone to demo changing one’s WiFi password in the settings section. Particularly moving from numbers to special symbols to alphabet and all caps alphabet.
While in the area to change the password, press on the nest device to change to special symbols, press on the nest device to change to alpha characters, press the device to change back to numbers, etc. Hope this helps.
Go to settings from the nest, and check to see if there's an update. I just set up my nest, and came across this video. I noticed that no one replied to you question. Anyway, that's something to try.
Do you have a fan wire? If you don't have a seperate fan wire you won't be able to use airwave because the Airwave feature sends a signal through the fan wire to keep running the fan independent of the air conditioner compressor.
It uses an algorithm to determine how long it will take to get a to a certain temperature and if it's scheduled to get to a certain temperature by a particular time it will pre-heat or turn on the heating to get the temperature to the desired temperature at the scheduled time.
Turn off auto schedule, and home away. Then set a setpoint in your schedule for 69 degrees at 9pm, 11pm, 1am, 3am and 5am. Then set your next set point after 5am to what you what the temp to bw throughout your day. Copy the schedule day to day. I have a video on how to schedule nest also : th-cam.com/video/BeWGMn8iZcM/w-d-xo.html
I set a lock so that the new ppl in the house will stop bothering it but don't remember the freaking 4-digit lock code, any idea of how to unlock it? The rhetoric says goto settings, but there is none.
Very vague. Do little research rather then reading manual before posting videos like this one so people can understand what the system does. You should call it Nest for Dummies the way it is.
