Honeywell Lyric Thermostat Installation and Some C-Wire Troubleshooting

[@harrelltackett3681]

My Husband almost went crazy trying to do this. I am so glad I found your video!

[@Joeyarhino1]

I take it all back!!! please disregard my previous posts. Your video saved my life!! I installed my thermostat (as the guide book said) and it would not work. I called the 1 800 number and the support tech told me I had to buy a wire saver device from amazon to power the thermostat. After a few moments of major frustration I watched your video again and followed your advice about the c-wire connection and BOOM! I was good to go! Please accept my apology if it weren't for your video I would be in the dark with this very expensive thermostat. I would also like to say its a shame that customer support doesn't know, or simply wont tell the customer about great fix you've posted here. Any way thanks again, I really cant express how thankful I am to you for your video. You rock!!!! Peace out.

[@slimofpgh]

Thank you! This is exactly what I needed! I had the same problem with the initial installation. My blue wire was going to Y. Moving it to C got it all working. This video saved me a lot of time, phone calls and maybe even on-site service.

[@KelsiSimmert]

THANK YOU!

[@RonVichar]

Man I feel glad that my G wire worked for the Common. Glad you got it working. 👍

[@mikm.6375]

Big man, your a life saver. Ive been fighting with this silly thing forever !! Moving that Yellow wire got it working !! 👍🏻💪🏻 ​ Update; That got me to the point where the thermostat lit up / came to life; issue then was while it would turn on the fan it would not turn on the outside unit / condenser (yes mine is a forced air ac / heat system & I realize that differs from yours) my end solution was to read the electrical schematic diagram find the + 24 v (in my units case it was brown) put the yellow back in its port & the brown hooked to the blue via the wires that run through the wall blue to the C, works perfect now :)

[@TerenceDIY]

That's awesome! I am glad my video helped you. Thank you for watching.

I just got the T-5 thermostat and tried to install it and ran into a wall when I turned the power back on. I found your post and instructions and Now it works! Thank you very much for uploading your post and instructions on this issue, I really do appreciate you very much. LOL! I was on the phone for hours waiting for the support line.

[@kendiener5447]

Your video was a life saver. When you finally said the green wire goes to a different spot, everything worked fine. Thank you very much.

[@ozzieman4404]

Thanks so much for posting this. I was getting so angry because I had the common wire connected to the same colored wire that was "extra" from my old unit. Nonetheless, I figured out that that colored wire was going to something else. In fact, the wire I needed to connect to the common was wrapped around the wire casing that went up to my thermostat. All I needed to do was connect it with a wire nut and voila!

[@464159]

Your video helped me. Moved the yellow down my lcd show up. But to depend on what AC unit you have and apps settings. Heater 1 is the way to go

[@TerenceDIY]

I am glad my video helped you. Thanks for watching.

[@alexr8836]

THANK YOU! I was getting really frustrated and didn't know about having to move the Green wire from G to C. Worked as soon as I moved it!

[@frankmyers5077]

Thanks, your Yellow wire trick was exactly what my 15 old furnace required. Green wire only turned on the fan.

[@Madesobe]

no need to apologize! you're so nice to have done us a favour by uploading this great tutorial - it really helped!

Hey man I really appreciate you making this video! It really helped me set it up in my new home! I’m a first time owner and I’m learning on how to do everything myself.

[@TerenceDIY]

You're welcome, Jose. I am glad my video helped.

[@claudianegron4495]

Terence. Thanks for sharing your solution! It worked for my set up perfectly. I tried other suggestions like adding an additional 5 the wire for the C connection and that didnt work for me. Swapping the Y connection over to the C connector worked. The device is working great now. Thanks again!

I bought a honeywell wifi, my house was built in 2009 so the ac unit isnt that old, was going to return it after the screen wouldn't turn on, thank god i found your video brotha! Y to C, C to Y worked for me!

[@hushanshan9338]

does your thermostat have 5 wires also? I replacing mine with then new T5 as well and I couldnt get the screen to turn on. Everything is in place I got G,W,Y, R, and C. So you're saying switch the Y to C, C to Y and will work? I also have a gas furnace as well.

[@David-bi4nc]

Did all the functions work when you did this? Any issues?

[@smith51-d5i]

Thanks so much you are awesome you saved me so much time. My dad always said to me "if you don't have enough brains to do something borrow someone else's."

[@misstingswigs]

Thank you for this video. My bf installed this last night and insisted that something was wrong with it, because it was not coming on. We were on the phone with support for hours. After watching this video I noticed you explained that push up/down switch for 1 wire or 2. I went and set it to 1 and bam! START SET UP appeared. Now I get to gloat and showboat all day pretending that fixed it on my own. Right on man!!!

[@patthompy347]

Great tutorial, my thermostat wouldn't power up. I switched my yellow wire to C and Violia, worked like a charm. Thank you for saving me troubleshooting and frustration.

[@imagesbykennedy8835]

This Works!! I never leave msgs on peoples videos, cause quite honestly I dont care to do so. but this is the only video I came across out of alllllllll the videos I watched in the span of 2 hrs that worked. Thanks Terence! your a real one. I wired my new wifi emerson sensi to my old ass 1980's configuration and boom! I was doing it!. After I was done I walked around my house with my chest poked out in front of my wife like I did it by myself. Salute!

[@candicemacdonald6442]

Hi again. I was just wondering, and in no way trying to blame. I installed the unit Sept 28 and just 2 days ago, the AC won't turn on. A tech just came by and said the conductor needs to be replaced. I have no clue about things like this. Do you have any idea if the new thermostat could have blown the conductor? or the way I installed it? Keep in mind, the AC unit is very old. So it may just be a coincidence and was simply it's time to go lol. Any advice is appreciated....and maybe some reassurance I did nothing wrong :)

[@Anavllama]

Good day. Read on if you have three wire thermostat bundling. In my case multizone hotwater 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 step applied. (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. :-)

I have a Problem, So our technician already got us set up with the T5 Lyric MONTHS AGO BRAND NEW, I stumbled upon this video cause for some reason the past 3 days.. the thermostat would SHUT OFF and then have that SAME pulsating light as you can see here 6:15 . Then I would leave it alone and observe (while timing the "loop") it would pulsate for a good 10mins, then it would turn on again and start the furnace-AC unit to its last setting ( i left it on cool since the house was kinda getting warm) then it would just run NORMALLY for a good 15-20mins till it will POWER DOWN AGAIN... pulsate for 10mins and so on with the "LOOP" I have tried Factory resetting the T5 Thermostat unit but nothing has changed.... same LOOP. Can anyone share some help here? i did'nt touch the configuration of the wires and i plan to go to home depot to buy a NEW unit, same product (if they still sell this in 2022) and then see if it works incase its not the current thermostats units fault. WOULD APPRECIATE ANYONE who can help. I just find it strange cause all these months its been working sweet...

if you have a 4 wire setup and need this yes you can put the green fan wire on c/common and go to the air handler and just put a jumper wire between g and y1 if its a heatpump problem if you have a gas furnace you better hope you have a heat seq for the fan.

My Lyric Thermostat came with a white jumper wire about two inches long. Did yours not?Not sure if I should jump from the Y to the c or not? The tech support guy told me to run a new wire from the furnace the thermostat.

[@TerenceDIY]

Hi, mines did NOT come with a jumper wire. Maybe they decided to add one since they realized the huge issue with installation. I wouldn't run a new wire to the furnace. If you choose not to install it the way that I did, you can purchase a power source.

Hey man. Just want to start off by saying thanks for making this video!!!! Just bought this today thinking I’m doing my family a service by being more efficient and smart about heating/cooling. Here’s the thing. I don’t wanna use the “Y” in “C” as I have AC and lately we NEED it here. I traced back my wiring and found two bundles. One going to AC and one to thermostat. The one going to thermostat does not have the “C”. The bundle going from furnace to AC unit has the “C” wire. Could I just fish a wire from thermostat and connect to the same “C” location on the furnace circuit board ? I would simply buy a length of wire, tie it to the bundle that comes out at thermostat and pull towards furnace. Install my C wire on panel and fish it back up through the walls and back to thermostat. Would this work ? lol

Hi Mario Patrick, I have been out of town for the last month. I wasn't able to check my messages until today. I do apologize for the delayed response. Did you ever get the thermostat up and going?

Question...Replacing the G wire for the C wire, when turning the heat on, does the fan come on as well or does it only come on when u turn the AC on?

[@chriswilliams5773]

For whatever reason this didn't work for my 4 wire configuration. Although it did get the thermostat to power on (it previously wasn't) The AC Compressor would not come on after. It would only blow regular air and I didn't even test heat. Turns out I actually have four more wires available for use if I need them so I will try use one of the extra wires to hook this thing up, but I'm not sure its going to work. As I already tried tying in one of the extra wires to the "Y" at the control board level and then using the thermostat end of new wire for the "Common" that also got me power, but still the same issue with no compressor kicking in. I will ask an HVAC Contact about it unless you have any ideas. I live in a condominium building. I believe I have what is known as a "package" whereabouts furnace/condensor/blower are all in one inside the condo. However far as I can tell it wires up just like your standard forced air or condenser unit. There was a jumper on my old thermostat as well. But you know Lyric says you don't need them so...

[@MrMrSaldana]

So what’s that other cable with a small box that’s comes with the thermostat...I saw someone connect it to the furnace..why is that ?

[@TerenceDIY]

Hi, I am not sure because this was a while ago however, I believe it was for a newer furnace and mines was from the 90's so I didn't need it. I could be wrong. I clearly remembered that I could not use it though. I apologize for not stating that information at the time of this install. Thanks for watching!

hey I have a question ? im a loss prevention officer for a department store that sells these I have been finding lots of stashed t-stats that are all ripped open but everything is always there may I ask what is those number codes on the front of the t -stat when u installed it what is that code for and does that code activate anything or something ? I believe there getting the codes off them for some reason

What if you only have 2 wires running to your old thermostat? And what to install one of this lyric t5?

[@micahmatthews1155]

So what does the original Y wire actually do and and is there any functionality that is missing because we don't use that wire?

I just had this installed in March, how do I turn the Heater off? It’s summer now and I don’t see a off button? I turned it down to 60 so it’s not kicking on the heat, but I would like to completely turn it off, Thanks

Hi Sassy, I sold the house this unit was installed in however, if I can remember, I believe you tap on the "heat on" up top and turn it off or press the "mode" button and it should give you an option to turn it off. It's a very simple method. I am sorry that I cannot provide accurate details. Let me know if one or the other works. Thanks for watching!

What would you do if there are only two wires on the original (old) thermostat you're trying to replace with the T5?

[@TerenceDIY]

Sorry for the late response. You will need a power adapter to power up the T5.

The homekit barcode is needed to connect to HomeKit. If you don't want HomeKit don't worry about it.

[@nelsonchukwuelue2045]

Thanks for your video. It helped me power up my Thermostat. Any idea why it won't cool down to 74? It is stuck at 83 and running.
