BEST VIDEO compared to all the confusing others and it got my thermostat working!!! I started at 6.30pm was about to give up at 12:20am until i came across your video and thought id give it one last shot. so glad that i did! thank you!
It’s amazing how someone could care enough to post a video like this to help others to not have these problems. Thanks for your concern you truly make a difference.
You're a life saver. I had limited time before work to fiddle with this thing and needless to say I had to take it back apart and put the old one back. After work I was back at it and no matter what, no display. I'm glad I stumbled upon your video because Honeywell was getting me no where. Your the man! Thanks
Awwwww, thank you!! I would have done the EXACT thing thing by forgetting that safety switch! This was a great video. I was actually getting a little frustrated and worried, but I stumbled on this video and it cheered me up and gave me a push to keep at it. Thank you!
This guy just made my night better! I went from being very angry to very happy because what this guy said worked! Thank you for making it easy to understand and making it funny! I'm not experienced in this stuff and the switch would have taken me for a spin as well. Thank you so much!!!
Thanks, John! Fixed my problem after a few hours of troubleshooting and right before I threw the thermostat through the wall. Glad I came across the vid.
Thank you! You are a life saver! Green wire changed and then finished watching the rest of the video to then feel dumb and remember the safety switch also lol we have air now! Thanks again for the helpful video!!
Great Video! I just purchased a Lyric T5 myself and love it! I had the almost exact same problem, my home was also built around 98, what I did was slightly different. One of the unused wires "which was blue" I put it in the C slot then tapped into my C spot on my furnace. I did notice my A/C was also using the C connection. I just wired them both tother and put it in C. tested everything and works perfect. My A/C unit isn't very large.
I tried that but was not as fortunate. I'm glad you figured it out and got it running. That seems to work for many people with this. Thanks for commenting.
Thanks. I installed my t5 in the winter and heat was fine, but the past few days have hot and the a.c. would kick on. Only the fan. I used the furance part of ur video to rewire downstairs and now it works.
That sorted it out for me. Thanks! I didn't follow it exactly because I realized I had a disconnected blue wire at both ends. So I just turned that into the C wire like it was meant to be.
Thank you so much for this , I have been struggling with this for hours , your jumping technique worked for me , again thanks man you made me a hero in my home
Thank you very much for this. I had the same issue. Did what you described and my t5 controlling both heat and cool even when not on auto heat/cool setting. Thank you again
Hey John, I just hooked my Lyric T5 and I had the same issue as you, however, I solved my problem a little differently and I believe you could have done the same. (I just purchased a 24 year old house with the original thermostat - 4 wire input, mercury tube kind) As you noticed, at your furnace you had extra wires wrapped around, specifically the blue one (see 4:42). At your thermostat, you noted you only had four, but if you had pulled your wires out of your wall, you would have seen your blue wire wrapped around there as well. In older thermostats, the blue was not needed as this supplies extra power, which is now needed for the Lyric T5. To easily remedy this, you should have plugged your blue wire into the “C” terminal at the furnace, and subsequently the “C” terminal at your thermostat. This would have provided the power you needed. Additionally, as a helpful guide, at your furnace, you have the following terminals: “W” “Y” “R” “G” and “C”. You’ll note that these all agree to the colors of your thermostat wires; white, yellow, red, and green with the exception of “C” which stands for common wire. If you switched them around at the furnace site and accordingly at your thermostat, is makes for a really easy hook up. Example: W (Furnace) - White (Wire) - W (Therm.) I hope this helps everyone else!
Hi. I cant get power on mine too. Will try again tomorrow. Maybe its also the door thing. Coz im running back and forth as well up and down but left the wiring door open. Hopefully that is my case. 😂
Call an HVAC. - I have no idea how to help you. Other than stating you have five wires at your thermostat site, you’re providing absolutely no other context or information to help you with your issue.
Lol I'm that one guy you just helped .. I'm at work now watching your video and I have every thing blown out all over the place with wire tester and panels removed and you showing me the button on the furnace I have not put the covers on for 2 days and that is where my problem lies
JHilmon I'm glad it helped. I'm enjoying the thermostat now as the weather is trying to decide if it wants to be cold or hot, I've found it useful to remotely access the temp control.
Some great tips, per the manual after a power outage or whenever the compressor outside turns off, it has a safety feature that doesn't allow the compressor to turn right back on till after a waiting period. During this period the current mode on the screen will flash which I noticed it was on your video thus the compressor wasn't turning on.
Very informative Castro, thanks for sharing your hate or disdain. I happen to have found great utility in having this and I like it. That’s what matters to me...
Good day. Read on if you have three wire thermostat bundling. In my case multi-zone hot water heating with 8 zone valves, 3 transformers and a propane boiler (and 5 pumps). This applies to those moving from a two wire honeywell thermostat (which covers the older mercury tube type, OR the LCD display type that needed batteries to display and programme). All my wiring bundles included a third wire folded back, which we will use for the Common Wire discussed. (no fan, no cooling, no heat pump, just heat) A. The steps are as follows. a. identify which wire is going to the load side of the transformer in the boiler room (should be the wire currently hooked into your R connector). Confirm proper wiring. b. identify which wire is going to the associated zone valve for that zone (should be the wire currently hooked into your W connector). Confirm proper wiring c. Work backwards from the zone valve motor to find the single (usually yellow wire) that is connected to a single wire coming in from thermostat wire bundles. (the other yellow motor wire is connected to the non load side of a transformer and in my case is maretted with a bunch of yellow zone valve wires and one other wire going to the non-load side of one of my three transformers) d. The single yellow wire connected to another single wire is how you find the W wire from the applicable thermostat and now you have located the correct thermostat wire bundle in the boiler room. e. trace the R wire from this bundle to the associated transformer as this is were the common wire needs to be attached. f. attach the common wire end in the boiler room, typically with a marette to a new piece of wire which is then attached to the SAME TRANSFORMER as the R wire BUT to the opposite side(screw). Synopsis A: With a multi-transformer scenario, I found the easiest thing to do was find the yellow wires (coming from my honeywell zone valves and attached to the motor) and found which one was connected to the W wire from the wire bundle - this was a one to one connection. (The other yellow wire was joined with other zone valve yellow wires and was connected to a wire going to one of my transformers on the opposite side to the load side on that transformer and thus not helpful.). Finding the W wire allowed me to trace back to the 3 wire bundle from that thermostat coming into a common wiring box. Now I could locate the Common wire and importantly the R wire. I had to know which transformer the R wire went to, in order to ensure the common wire went to the opposite side of the same transformer. B. At thermostat the following steps applies: (a) Ensure the R and RC switch is down, in the 2 slot position (both holes exposed) (b) Connect the C wire to the C post/slot (c) Connect the R wire to the R post/slot (d) Connect the W wire to the W post/slot (e) create a little jumper wire (u shaped with exposed copper at the ends) and CONNECT R to Rc Explanation: The R and W wires form a 24 volt circuit WHEN the thermostat calls for heat, (the thermostat joins the R and W wires creating a circuit for juice to flow). The jumper between R and Rc creates and additional circuit between Rc and C WHICH HONEYWELL OMITS in all their literature. Tech support kept telling me I needed four wires, R,W,C and Rc and that I needed to create a similar circuit to RW, using C and Rc. Well by using the jumper I effectively used the Juice on the R side sharing it with Rc. Since the honeywell internally connects Rc and C, the needed circuit is established from the get go and the thermostat powers up. When the thermostat calls for heat, the R and W are connected and the zone valve motor turns on and operns the valve (tested and works). So the two keys are (1) knowing that honeywell uses the Rc slot and C slot for power to the unit and (2) the C wire has to be on the same transformer but opposite side in the boiler room If you have the different standard square sized honeywell thermostat or find the video on you tube for WIFI honeywell, you will see that they have the jumper already in place!!! Good luck with your own situation. :-)
If your still having problems connecting to wifi you need to reset your router and reset your t5 then use your iPhone or apple product to install the wifi. It won't let a android phone to set it up. But after it's set up you can sign in and it works on the android. I've been having this problem for a few days after I did that update. So if your having the same problem just reset your router and reset your lyric termostat
If thermostat is flashing "cool on" or "heat on" it means it is giving time for the system to rest before restarting again. It will start up again in 5 minutes. It should not be flashing once it starts. It flashes like that to protect your compressor from cycling on and off and burning up. If you use the app to do it manually you are bypassing this system so be careful.
Why didn’t you one of the extra wires at the furnace and the thermostat. For example: connect the extra blue wire at furnace to C terminal and the blue wire at the thermostat to the C junction on thermostat and the rest of the other wires R to R, W to W, G to G, Y to Y on thermostat
I have been researching various options like everyone else. From what I gather, using this method (green wire at the thermostat and then HVAC Control panel noted in the video etc) should work. However, it comes at a sacrifice....you will no longer be able to run just your fan. I never do this and so guess its not a problem. Just wanted to mention it.
@@johngueli6293 thanks for a quick reply. One question. AT My thermostat there is Red wire R and Rc (two separate terminals). Between them is a jumper cable. I assume I remove the jumper when installing the T5?
One more point not mentioned here in the video. Another site (link below) says in the HVAC control panel, after moving the Green wire to C, there is one more step. You need to add a jumper wire between the Green terminal (which is now empty) to the Yellow Terminal. I see its there in your video recording of your control panel. www.diysmarthomesolutions.com/smart-thermostat-c-wire-explained/
I am right now in same spot where you were...I bought T5 and when I opened my existing thermostat, nothing plugged in to C wire!!! Not sure what I am going to do b'cas I am not a HVAC or a Electrician. Most of the videos on you tube shows simple change over to new one but thats not the case for me.
Hi I live in Florida with central ac with heat pump I hooked the t5 up but I’m not getting ac the heat pump is coming on wired it up how it was on my old thermostat
i hooked up the t5 and noticed that once it wants to move to heat, the entire device reboots and shows welcome. only happens with the heat and not cool. what should i do?
Thanks for the video! I tried it and started to worry a little bit. Figured I'd sleep on it and try it. Where in the app is the settings for the automatic switch for the AC?
Dan Yacobucci once you have configured your thermostat, you should click the menu icon in upper left and be able to see “thermostat (my lyric” or something to that effect. Click it and it will open an option for you to see “auto changeover”. Good luck.
Hi, thanks for the great video. Does this setup allow for the fan control from the T5? The Honeywell solution to use the green wire removes the ability to operate the fan manually.
hi i just bought a Lyric T5 and i had before old mercury thermostat.in my old one i have four wires Black Red green and white. i installed new Lyric T5 and also connect all wires but after all this.i see my fan is turn on buy my Ac is not turning on.i am trying to figure it out where is the problem.can u help me out here.
yadwinder singh I’m not an electrician. Suggest you look at the wires on your furnace to make sure they’re on the correct terminal. Go to my video around the 6:03min point for example. So, for example: if your red wire is connected to your “R” terminal, make sure the “R” wire is in the “R” slot of your thermostat. Etc. if you’re struggling, I strongly suggest you call electrician. Good luck.
Mathan Tharmarajah I’m sorry but I don’t know. I’m not an electrician and was just happy to have figured it out. Wish I could help. I haven’t had any issues and it’s going on one year.
How do you change the actual control wires at the control board on your furnace? Are you suppose to unscrew it? Sorry I completely don't understand (not for the thermostat unit, but for the actual furnace control board).
Amandip Dhillon I’m not sure I understand what you’re asking. The wires are screwed into the board on my furnace. I just loosened them up to do what I needed.
Dave Fabris Perhaps after many complaints, Honeywell has updated their instructions?!? Just curious though, if everything is in the instructions, why were you still seeking videos on CZcams for it?
amanda muzechenko I'm not positive but I believe it does. I'd suggest taking your thermostat off the wall to look at the wiring configuration first. Honeywell has a decent 24hr customer service line too you can call. Good luck. It's a useful gadget
Looks to me like you have extra wires tucked away. Definitely had extra down at the furnace. You sure you didn't have extra wires hiding away behind the wall? Could have used one of them to be your C wire.
Brad Mugford I did have the extra wires tucked in behind the wall. I tried using one as the c wire, which I connected to the c terminal on the furnace and then into the thermostat. It didn't work for me, so IDK. This configuration worked and I'm okay with it.
Honeywell is full of shit! ! No one should have to go through this much trouble just to install a thermostat . I took it back off . It was getting hot and I was frustrated.
5 trips up and down the stairs about to set house on fire until I saw your video. Safety switch got me as well. Thank you.

Good day. Read on if you have three wire thermostat bundling. In my case multi-zone hot water heating with 8 zone valves, 3 transformers and a propane boiler (and 5 pumps). This applies to those moving from a two wire honeywell thermostat (which covers the older mercury tube type, OR the LCD display type that needed batteries to display and programme). All my wiring bundles included a third wire folded back, which we will use for the Common Wire discussed. (no fan, no cooling, no heat pump, just heat)
A. The steps are as follows.
a. identify which wire is going to the load side of the transformer in the boiler room (should be the wire currently hooked into your R connector). Confirm proper wiring.
b. identify which wire is going to the associated zone valve for that zone (should be the wire currently hooked into your W connector). Confirm proper wiring
c. Work backwards from the zone valve motor to find the single (usually yellow wire) that is connected to a single wire coming in from thermostat wire bundles. (the other yellow motor wire is connected to the non load side of a transformer and in my case is maretted with a bunch of yellow zone valve wires and one other wire going to the non-load side of one of my three transformers)
d. The single yellow wire connected to another single wire is how you find the W wire from the applicable thermostat and now you have located the correct thermostat wire bundle in the boiler room. e. trace the R wire from this bundle to the associated transformer as this is were the common wire needs to be attached.
f. attach the common wire end in the boiler room, typically with a marette to a new piece of wire which is then attached to the SAME TRANSFORMER as the R wire BUT to the opposite side(screw).
Synopsis A: With a multi-transformer scenario, I found the easiest thing to do was find the yellow wires (coming from my honeywell zone valves and attached to the motor) and found which one was connected to the W wire from the wire bundle - this was a one to one connection.

I had to know which transformer the R wire went to, in order to ensure the common wire went to the opposite side of the same transformer.
B. At thermostat the following steps applies:
(a) Ensure the R and RC switch is down, in the 2 slot position (both holes exposed)
(b) Connect the C wire to the C post/slot
(c) Connect the R wire to the R post/slot
(d) Connect the W wire to the W post/slot
(e) create a little jumper wire (u shaped with exposed copper at the ends) and CONNECT R to Rc
Explanation: The R and W wires form a 24 volt circuit WHEN the thermostat calls for heat, (the thermostat joins the R and W wires creating a circuit for juice to flow). The jumper between R and Rc creates and additional circuit between Rc and C WHICH HONEYWELL OMITS in all their literature. Tech support kept telling me I needed four wires, R,W,C and Rc and that I needed to create a similar circuit to RW, using C and Rc. Well by using the jumper I effectively used the Juice on the R side sharing it with Rc. Since the honeywell internally connects Rc and C, the needed circuit is established from the get go and the thermostat powers up. When the thermostat calls for heat, the R and W are connected and the zone valve motor turns on and operns the valve (tested and works).
So the two keys are
(1) knowing that honeywell uses the Rc slot and C slot for power to the unit and
(2) the C wire has to be on the same transformer but opposite side in the boiler room If you have the different standard square sized honeywell thermostat or find the video on you tube for WIFI honeywell, you will see that they have the jumper already in place!!!
Good luck with your own situation. :-)

If your still having problems connecting to wifi you need to reset your router and reset your t5 then use your iPhone or apple product to install the wifi. It won't let a android phone to set it up.

Hi I live in Florida with central ac with heat pump I hooked the t5 up but I’m not getting ac the heat pump is coming on wired it up how it was on my old thermostat

Hey John. What about if you have only white and red wire. Can you still hook up the thermostat?
i hooked up the t5 and noticed that once it wants to move to heat, the entire device reboots and shows welcome. only happens with the heat and not cool. what should i do?
Sorry Chudi, I don’t have an answer for that. That sounds more like a factory defect or a short that is causing a loss of power. Best of luck to you

So when the Honeywell tech said move the wire from G to C he meant on the T5 AND the blower/heating unit, right?
I have thecsame question. Could you please answer. Seems to be the case but wanted to double check to be sure.

How do you change the actual control wires at the control board on your furnace? Are you suppose to unscrew it? Sorry I completely don't understand (not for the thermostat unit, but for the actual furnace control board).
Amandip Dhillon I’m not sure I understand what you’re asking. The wires are screwed into the board on my furnace. I just loosened them up to do what I needed.
Ah okay thank you, that is all I needed to know!
Good video but the audio was a chore.
yea...Read the instructions...it explains all this in one paragraph
Dave Fabris Perhaps after many complaints, Honeywell has updated their instructions?!? Just curious though, if everything is in the instructions, why were you still seeking videos on CZcams for it?
Does this work for Electric Furnace?
amanda muzechenko I'm not positive but I believe it does. I'd suggest taking your thermostat off the wall to look at the wiring configuration first. Honeywell has a decent 24hr customer service line too you can call. Good luck. It's a useful gadget
I think you will not be able to just run the fan to circulate air without air or heat turned on.
FBAHSY it has been working perfectly fine through all seasons the way it is.
Looks to me like you have extra wires tucked away. Definitely had extra down at the furnace. You sure you didn't have extra wires hiding away behind the wall? Could have used one of them to be your C wire.
Brad Mugford I did have the extra wires tucked in behind the wall. I tried using one as the c wire, which I connected to the c terminal on the furnace and then into the thermostat. It didn't work for me, so IDK. This configuration worked and I'm okay with it.
Honeywell is full of shit! ! No one should have to go through this much trouble just to install a thermostat . I took it back off . It was getting hot and I was frustrated.
Uhhhhhh...... I'm glad I would never do something like that.... JK. I did the same thing.
Take your fingers off the phone's mic. We can't hear you
You kept covering up your mic largely muting your voice.
Dash SS thank! I did this for free to help others. Not to try a career as a CZcams star. LoL. Hope it helped
Thank you
