How To Install Ecobee3 Lite Smart Thermostat

[@TROLLSTIN13]

7 years later after learning about electrical work, I finally understand these types of videos. I was doing wrong the whole time.

[@TheDubVee]

I'm glad guys like you exist. The installation directions weren't too bad, but it's so much easier to follow along when you have someone showing you as you go so thank you!

[@larrybertsch3907]

Good job explaining. I was going to hire a HVAC company to do this, but you proved to me that I can do it myself. Thank you.

[@jasonfreddie1276]

I know it’s late, but how easy was it for you know looking back? Any problems manifested?

[@TheMrKordunas]

Thx for video.Easy and precise explanation step by step My problem is once I removed old thermostat I found out 4 wires,2 brown and 2 black😂😂😂😂😂

[@claudiabarcenas9091]

Thank you ! I just helped my mom install hers! Took us about 2 hours 😂 but we got it done . We thought it hadn’t worked, but realized we needed to put the panels back on the furnace.

[@TheHAMMER675]

Mission accomplished! My colors were all different and I had 2 four-wires coming in, in addition to the thermostat two-wire. I just followed your instructions and it all worked. I ended up with two of my lines going into the pek having to be doubled up because of my extra four-wire cable.

[@fortoday04]

Used this video to install it. Worked out well. Old wiring had RC and RH bridged. Googled to see that I don't have to have them bridged

[@oxygencrossroads]

This was very helpful, but I did have to make one modification, because there was not a wire on the Y terminal. I found someone on Reddit saying I should look in the furnace for a wirenut "floating in the air" and that's where my Y wire was! I removed the old Y wire from the wire nut and added the Y wire from the Power Extender Kit to the floating wire nut, then continued just like the video.

[@gentrywilliams9680]

Omgosh! So detail. Now this I understand totally and have no experience in HVAC

[@bgarcia9788]

Where did you get the rectangular trim plate?

[@tkeeg]

Wow, great video filled with all good information! Thanks so much for taking the time to film it, edit it and post it. I especially liked your tutorial of the wiring scheme in the HVAC unit and what each letter represents. Not many people will take the time to detail it the way you did. Well done my friend!

[@raybossworld4541]

Yo this video help me out a lot, believe me when I say I was stuck an lost, because I had to install the PEK and then after that I was clueless, but your video save me, thanks a million.

[@abravoc81]

This was amazing! Thank you, this made installing my thermostat so easy.

[@ankitrdeo]

Thank you so much! Your video was exact to point and super simple to understand. This is the first time I have tried doing anything electrical of this sort on my own and you made it super simple. Thank you!

[@Xplorewme]

Thank you, ours didn’t turn on because we didn’t put the control board cover on, if anyone is stuck and theirs doesn’t turn on make sure you do that.

[@utahalex]

Dude! This video was awesome and perfect. Provided me with everything I needed to install this ecobee lite 3 with confidence. Thank you!

[@ultramagaandasemifacistdep8598]

One of the best instructional videos I've watched, very easy to follow and very detailed. Good job!

[@denniswashington7319]

Thanks so much for this video, just like you said I got goofed up on the re wiring but got it figured out after a few rewarches lol thanks

[@OneHourSmartHome]

Great to hear! Glad you figured it out! Thanks for watching and the comment!

[@brokensword8402]

I'm an idiot. I've been watching a bunch of YT nature videos and kept think I had a miniaturized YT screen popping up. It was you covering the sensitive information. Lol. In any case, thanks for the helpful tips. I just got one today!

[@tomrum42]

This is the first video that I have seen that explains and shows how to install the C wire adapter. Do the installation instructions that come with the Lite explain or illustrate the process too? Great video. Thank you for taking the time to do the video.

[@Stallion23]

Can you provide a link for the faceplate you used.

[@Jaboomf]

Thank you so much for this instructional video! Question: I have a small black wire connecting the RH and RC terminal at the thermostat. What is that and do I need to do that too on my Ecobee lite? Thank you for your help.

[@Jbellma54]

I have the same scenario, is the jumper needed for the Ecobee as well?

[@tdeeez]

Same question here!

[@jenniferarink2135]

I read elsewhere that you do not need a jumper since it is a smart thermostat. I have the same setup.

[@tdeeez]

@@jenniferarink2135 I’ve been using mine with no jumper and it’s been fine. I had one on my old thermostat fwiw

[@carlyann881]

Thank you so much for this video. It was so easy to follow!!

[@mrchad97z49]

how did you know to connect the Red wire to the RC port on the new thermostat? On my old system, both RC and RH have a jumper that ties them both together.. Maybe my old thermostat requires power on both? Either way, how did you know to use the RC port? And not RH..

[@srt5musik]

In the wiring instructions they all show red on rc if it's a single transformer system. I found this out because I didn't read the instructions and hooked up rh at first like I do with every other thermostat and it didn't power on 😅

[@angelamorehead6645]

Thank you so much! I had tried to install my Ecolite3 several times, but got frustrated. The instructions were not as clear as your instructions. I appreciate your help! It is working great now!

[@michaelhecktus512]

Great tutorial, system is up and running! Thank you!

[@dominickotowski9358]

Thank you for the detailed information on the installation.

[@CPTWalt]

Great vid, easy to understand and made me more comfortable attempting this on my own. Thanks!

[@kbinoyn1]

Must appreciate this video. I have exactly same wiring as you have. But why my ecobee3 lite keeps rebooting? Please suggest

[@dominoez21]

Thank you for the super clear explanations and close up video footage for all the connections that need to be made. Very helpful!

[@mons820]

Thank you! Very easy to follow, your step by step instructions!

[@eatdrinkbemerry3456]

Hey, thank you so much! Your video was very helpful and helped me get the thermostat installed nice and easy.

[@abuenas07]

Thank you so much for this video I got my ac unit working and my new thormstat

[@anthonycraig274]

Like you I have a blue wire that is the Y wire. However, my blue/Y wire doens’t connect to anything. I don’t have a cooling system, do I connect it anyway?

[@medinarpinME]

I’m using a C-wire adaptor that plugs in an outlet on my Google Nest…will that work or do I still have to use the included adaptor?

[@SCAMATICS777]

Great video. Curious, can you just run a c wire from the board down the same line as thermostat wire out the wall instead of PEK adapter?

[@skankinmat1]

Thank you for this super helpful tutorial

[@sethaldridge730]

This video was awesome to follow.

[@OneHourSmartHome]

Glad to help and thanks for watching!

[@kauaireed9006]

Great video 11-21-21 - maybe you can advise ,,,, I am so confused, we have electricity and use a heat pump. Our tech told me we should see a explanation point next to the flame icon when the heat pump is running and not auxiliary heat, I never see a explanation point. So I ask you should I see a explanation point? Please advise, thanks.

[@mashacamashaca877]

Wow! Very well explained. Thank you. I have a question though... My Honeywell has 5 wires connected. (W,Y,G,R,Rc). What do I do different in my case?

[@davidewan3]

did you figure this out? I have the same thing - RH and RC from the thermostat although they both go to the same post. I figure I need to splice them and stick that in the adaptor - or maybe not because they are power out to the thermostat? probably a key point missed in this video?

[@mashacamashaca877]

@@davidewan3 yes I did. I ended up using a wafer relay to separate the 2 signals. I’d have to look at my notes if you want more info

[@xamill22]

I have a 2 zone heating system. My first floor ecobee does have a common wire, but my 2nd floor ecobee does not have a common wire. Should I add the power extender kit in order for it to work? (Currently not working)

[@ByPennyMorgan]

So, if I have a common wire, then I don't need to add the adapter on the HVAC unit? Correct?

[@RayRv607]

Did it come with a common wire adapter?

[@katier9590]

Thank you so much. Mine was wired wrong

[@murphyslaw7815]

I have a blue wire on an E terminal. Should my white wire go to W1 and the blue E go to W2? And what's the difference between Rc and Rh?

[@Tkh21209]

So we turn the breaker off before we begin?

[@cowboyboots9901]

6:40 seems simpler to run a separate common wire to the thermostat.

[@cbain3070]

If I do not have a computer in my home will this work .

[@matthewjbauer1990]

I wanted to get something other than a Nest and was looking at an Ecobee 3 lite or something similar as price was right and features were better AND they came with bezels and a C wire battery pack adapter kit. When I went into my furnace and removed the 2 panels, I found the control board is hidden behind a panel that is blocked by the large vent stack My furnace has a vent coming out of the front inside behind the door and up through the top (as opposed to directly out the top or out the side then the top). Any advice? I may need to add a C wire adapter in the future with my Nest as it doesn't seem to charge all that fast and it acts all weird when controlling the HVAC system OR I may upgrade.

[@CherylynnLima]

I don't see that black box wit the letters anywhere on mine?

[@chriss4365]

How does that device make a common wire? How did you turn the green wire into a common wire?

[@fbenfrank]

For the people that don’t have a common wire, but a B connection that’s your C (common wire).

[@alexandergomez3491]

My existing thermostat is mounted in s small sliver of wallspace (about 5 inches wide) between two doors. Do I need to use the faceplate? Can I mount it as-is I doubt there is any faceplate that can fit in that wallspace.

[@oorahoofah]

If you have more than one thermometer (say 6) that doesn’t have a common wire, do you need to install 6 separate common wire adapters? I’m guessing the answer is yes

[@kulwinderbhatia584]

excellent video , really explained every detail

[@googlreviews7813]

So I have following wires... W2 W/E RC (Which is jumped to RH) ? Why? Y G The jumping of RC and RH has ne confused, would I still need to jump them on new device?

[@Qchiko]

Thanks for the great video! Great quality and instructions were on point!

[@base698]

Where's the backplate you show? I have the same model Honeywell thermostat.

[@josephlemons]

Would flipping the switch by the HVAC & the breaker damage anything or not?

[@JobinJoseph2020]

I am replacing my Honeywell with ecobee. I see that on my Honeywell there is R and RC wire but ecobee has RC and RH, how should I connect the R & RC ?

[@sherryjasper7183]

Don't have ac unit. Is there a video for installation without ac?

[@jacobkowski7705]

In case in 10 years I want to replace this Ecobee with another brand, how do we connect wires to the new brand where there is no PEK wire socket?

[@michaeljohnson1151]

This will still work without wifi correct?

[@ClintEwingFreestyle]

Thorough thank you 😊

[@tdeeez]

Perfect. Thanks for this!

[@dansalgado1592]

Fantastic video, very informative, thank you!

[@charcos73]

Good video I have a question? How did I connect a humidifier? Thanks

[@jonkc3635]

ecobee support here. The ecobee3 lite doesn't support accessories such as humidifiers. For more info look up ecobee accessory installation.

[@marissatuazon4858]

Good information and you explain it well.

[@ashirwadclin3883]

Thanks it’s work

[@soldwithjoel]

Solid video! Thanks for the help

[@joshuarozario5654]

Thanks for that detailed video. Can a house run on two different thermostats. In other words, EcoBee Lite on the 1st floor and a Honeywell thermostat on the second floor. Is that an issue? Will the wiring conflict?

[@gregsmith7391]

I'd like to know too. I would like whatever tstat to kick in the AC as needed. Ie might need more cooling at night in bedrooms upstairs and would like it to override. Can I connect 2 ecobee thermostats but the upstairs one for AC wires only?

[@isaurogonzalez8648]

Thank you good job

[@HelloSnake]

So when using the power extender kit do you have full functionality? Or do you lose the fan feature like when using the trick to change the G wire into a C wire, or something like that? I watched another video and it seems the PEK turns the cooling wire into both a cooling wire and a fan wire, whichever one is needed at the time. Cool.

[@courtenayblair2279]

Favorite part of the video: using a Nest screwdriver to install an Ecobee lol

[@reginogar1]

I cant find the off switch can I just disconected it?

[@michaelmcquivey8316]

You are awesome! Thank you so much for your video. You made it easy.

[@victorhoe2321]

I was fine until you started to talk about the Power Extender Kit (PEK). Was PEK part of the original EcoBee 3 Lite with the Common Wire Adapter OR was that a seperate purchase item?

[@Al6sham]

Thank you , you were very helpful

[@Dwelly70]

Had to shut the video off after the 100th time he said go ahead gzzz

[@hexgameyt8637]

Do you have to open the HVAC control board if you have a common wire on thermostat? Great video

[@crypt0sFX]

No

[@countyboy2874]

Just watched your video since I bought this same thermostat great job!. Do you have a link to the rectangular cover plate you bought because I’ve searched all over Amazon with no luck?

[@MrWharfrat05]

Excellent video!

[@carlmalone1982]

What do i do if i don’t have a W wire

[@aronjohn84]

What if the Rh and Rc are jumped

[@jakemaynard9476]

My thermostat has two jumper wires… what should I do?

[@zzman5306]

Very good video

[@eyyteam]

Thank you great video

[@mattproto5486]

Where did you find the wall plate?

[@gak0090]

it's at the very bottom of the box, you need to take everything out

[@kirk8985]

Thank you

[@TurboLaserMega]

Why is there a 14 gauge wire hooked up to your Y terminal?

[@OneHourSmartHome]

That was just the gauge that was orginally run for the control wiring.

[@checkdacontract]

Great video. I'm only working with an old furnace underneath the house in a crawl space.- no a/c. What do you do when there are only 2 black wires coming out of the wall into the old thermostat?

[@actowingfamily576]

I wired everyhing correctly. But i believe the C wire may not be connected from the furnace, so its not powering on!!! 😒😒

[@petearchie61]

Question: I have a common wire but when I hooked up the thermostat it still did not power on. I then looked at the panel on the furnace and the common wire was not connected. Hooked it up tried again still no power. The only other thing I can think of would be the green wire next to it is on the wrong terminal, but wouldn't that keep the furnace from working also. I have the thermostat that was replaced in the video. Update: My problems was the way my furnace is wired I can't use a thermostat that needs to hard wired, it has to battery powerd

[@eddiepatterson1479]

if its easy to do why not just drop a 5 wire or 8 wire for the added wires needed

[@psy-locked2366]

Thank you! I also replaced my piece of shit Honeywell thermostat, @Honeywell, you guys really do know how to make shit.

[@Frankwhite73]

I have a E wire and a aux wire 🫠

Don't install it you'll regret It wants to control temperature in your apartment and I figured my old manual thermostat was way better option
