Thank you ! This video saves me from having to run more wire! Great video 👍
I just bought the Honeywell c-wire adapter for the furnace. Works perfect and DIY EAZY
You have a nice voice. It's clear that you want to help people. Thanks.
So nice of you! Thanks so much for the support 🙏🏻
Wow!!! I swore i had the "C" wire the whole time because its usually blue! But in my case the "Y" cable which is usually yellow was missing and was instead blue! this helps a tone!!!!

Not sure if the name or link changed but it now directs to "briidea common wire kit" and specifically says "cannot be used as R power or C common wire" though seems very similar to what you've wired up for a C wire. I assume there's no issue then, just add it says it can't be used a C wire.
@@mikeb4629 On t-stat side, C is not connected to this kit. C use original dedicated wire. On furnace side, the adapter needs C to do its own work.
My Man!!!
Another Great Video...Happy Holidays.
Man, I am so happy that I ran across your TH-cam videos!!!!
Thanks bro! Glad you are enjoying the content. Cheers 🍻
Thanks for making thing's simple for guys like me .
Most welcome 😊
Common mistake I see with these c wire how to videos. You pull off the old thermostat and assume there is no c wire. It may be there it's just not hooked up, look at the other end of the cable in the furnace. Many of my friends and family that put in a smart thermostat don't need the adapter. Most houses I've seen that are 90's and newer use 8 conductor cable for the thermostat and only use 4 of them, the others are tucked back in the wall. Investigate a little further see if rerouting a new cable is possible as it is preferable. 8 conductor thermostat wire can be found at local hardware stores for a few bucks.
Yup, exact same scenario for me . Idk where to connect the C wire though in the furnace to get the 24V . It’s a older furnace .
I don't even have a damn furnace to check wiring. I live in a condo so all I have is a breaker, water heater and some wiring section for Xfinity lol
This comment helped me! I'm only reading 16v on the spare wire behind the wall (prev thermostat used 4, r y w b, but B was hooked to Y and the Y is the spare wire behind the wall). I taped the yellow wire up since idk why it's getting low voltage
I did have to install one of those add a wire units for one client of mine. For another, I was able to run a new thermostat cable to get enough wires. On the thermostat I just installed for my home, it indicated that I could wire G to C at both the thermostat and furnace, with a jumper between Y and G at the furnace. I guess you lose the ability to control the fan manually, but it still runs when heating or cooling. My old thermostat only used 4 wires, so I thought I would have to deal with that. Fortunately, there were enough wires in the thermostat cable. I just needed to connect one of the unused wires to the furnace's C terminal. BTW, I think of C as Cyan, thus using the blue wire.
Great thank you as always 😊
Nice job!! I’m going to have to look at the video a few times more to completely understand….I know it will come clear!!
Yes the diode just uses one wire to send a signal to the unit in the furnace is all. The instructions are very easy to follow. If you have any questions, email me at diyhvacguy@gmail.com Cheers
Killing it man, good videos
Thanks bro!
If people want something that is easier and cheaper for a smart thermostat. Buy am Ecobee that comes with a PEK (power extender kit). Not to mention the PEK is magnetic.
I was literally minutes away from calling in the professionals then I came across this video. Thank you so much for the he add-a-wire suggestion!!!
Did the sheet metal screw go into the squirrel cage?
Thanks again for a nice video bro
Always welcome
Super cool. Have been following your videos and been doing what you have shown as far as spare parts and converters. Thanks. How about humidifiers with smart controls that measure outside air with inside air to determine proper humidity in the house. I have a furnace add on that i have to adjust during these weather extreme swings. Thanks again.
I’ll look into doing some videos on humidifiers. Definitely crucial out here where there is low humidity! Cheers
Good Job!
I'm waiting for the fallout comments because you used your channel locks for a "hammer"...LoL. I like the Wago fasteners you used I've never seen them before much simpler than the plastic anchors.
Yes! They’re amazing. Pick up a combo set at our Amazon store in the video description! Cheers friend
I need a mini hammer in my hvac tool bag 🤣
@@diyhvacguy LoL Naaaah if you got seamers in you toolbox your good! Agree? 👍 Have a great Christmas holiday.
@@diyhvacguy I wanted to ask you what state do you live in?.
I wished you would have mentioned the small fuse at the furnace that can be blown if power isn’t shutoff from it. The blown fuse will derail the new thermostat installation. Good video.
Ecobee makes a model of their smart thermostat that includes a pek(power extender kit). It connects to your furnace circuit board.
It's really nice that they include it when you purchase one, where as if you purchase a Google Nest, you must purchase the PEK as a separate.
I think Ecobee is just a nice product overall compared to Google Nest.
If you want the trim kit as well, you must purchase that separate from Google, where as with Ecobee, you receive it for free.
Yeah he has a video on installing that
@@enrick7518 just bought the ecobee smart thermistat enhanced because it has the pek+ needed it for a whole house dehumidifier, removed my nest learning that was reading 20% higher humidity. Screw Nest. Oh I like the geofefencing on the ecobee. Set home, sleep, away, with radius. Humidity is very close too.
@@Nolaman70 interesting.
I was wondering if Ecobee had a solution for those with humidifiers. Thanks for sharing this.
@@enrick7518 it can be programmed for anything but there is only one on the enhanced the next model up Premium has 2 PEK+ and PEK- I think. I will need to use a relay coil to pek+ other side of coil to common and the 2 contacts to DH DH on my dehumidifier. Easy enough.
Great videos! Quick question…. I have a n older York diamond series furnace, it’s a 90+ up flow 2 stage, I would like to add a Amazon smart thermostat, I have a 5 wire now, I have no c terminal on my furnace board, could I just run 18/6 wire and connect the 6 th wire to b on my furnace board which is connected to the white wire running out to my condenser and the c terminal on my thermostat? Thanks in advance!
Thanks for the great and clear explanation on how to install this add a wire. I wanted to ask; we have a Lennox packaged unit that came with a Lennox smart thermostat. The thermostat just stopped working right after the 5-year warranty, and the "authorized dealer" installed a Honeywell T6 Pro Wi-Fi thermostat. This new thermostat cannot rev up our unit to kick in the 2nd stage cooling that was working with the old Lennox thermostat (iComfortE30), and the dealer told us that we needed an additional wire to make this 2nd stage work. Running a 2nd wire would be cost prohibiting for us, based on out setup. Would the add a wire solve this? we also only have 4 wires coming from the unit on the roof to the inside where the thermostat is at. Thanks for your time in advance! 🙏
Where do I typically find the other end of the thermostat wires? I apparently only have 5 at my thermostat (no clue wire) and I'm trying to I stall an exobee smart thermostat. Do I look at the unit outside, or is it the handler in the garage I have to explore in? I'm kinda thinking just get a new wire and run a new 7wire cable and be done, no converters needed.
Looking at the connection diagram, both G (fan) and Y (AC unit) are connected to a single "blue" wire through each own diode. Would it be better to connect W and Y through diodes because Heating and AC never work together? Do you know if this Add a wire adapter works with Amazon thermostats?
What are the best anchors to use on plaster walls?
Cleaver, thanks
Glad it helped
Thanks for the video informative only problem is is you tell us about these great anchors for the drywall but nowhere name what they are or where we can get them, inquiring a minds want to know
Link to those is in the video description :)
Great video! Now is there a way to add a 6th wire for humidity control? I have a whole house humidifier in the basement with a separate controller next to it. I'm getting an Ecobee thermostat and I'd like it to control the humidifier. Any good pocedures out there for this? Cheers!
Yes the Fast-Stat 5000 will add more then one wire 👍🏼
I'm not sure how all this works. But instead of buying that device couldn't you splice wires from the g so the power goes both to that and the c?
How would u wire this if u need it to add a 6th wire for 2 stage heat? I have a 5 wire running already. Just not understanding how to use this for the adding of 6th wire. Thanks
Can I use add a wire accessory for Honeywell Battery powered thermostat T6 pro series? Thanks
How does this differ if I'm swapping out two thermostats, one on each floor? Separate diode for each floor?
I'm trying to go through all your videos. I have a question for you the thermostat wire from my furnace to the thermostat is two wires. I was thinking of maybe putting one of those smart thermostats in which it sounds like two wires ain't going to do it. The basement is completely open so I assume I could change the two wires out to maybe a four or five wire would be your recommendation? Thanks Michael ☺️
Honestly it will be easier to do this add a wire kit. You can go from a two wire to a system that will fun heat and air conditioning.

Michael Sheeder from a Gas Technician, my advice would be to install a new 5 conductor t-stat wire and if possible even an 8 conductor if you want to prepare for the near future. Especially if your basement is already open, now is the time to do it. Any other advice is just a money grab or bad advice altogether. Cheers hope that helps!
@@DonovanRocheleau thanks for your help. Michael
Force air/gas furnace, central AC. My control board has no yellow (Y) spot on it. Y from t stat connects to red going to AC doesn’t go to furnace board. W from AC connects to C on control board. From T Stat, R to R board, W to W board, G to G board. C on board only goes to W on AC wiring. My T stat wiring has 5 wires with B not used on either end. Do I just connect T Stat blue to the C board and good to connect smart T stat on wall?
At 10:15, I would have used a Wago.
If you only have heat via hot water (baseboard), IOW no air conditioning and no fan, you're probably only going to have two wires going to your thermostat. I simply wired an ac adapter to my smart thermostat to power it..
Purchased an add a wire briidea Model HTACC-01 from amazon as per the link you provided, and it came with no instructions . On- line instructions state; Cannot be used as ''R'' power or ''C'' common wire. Is this the wrong unit?
I need to know how to do this. The new thermostat has been sitting in its box for over a year! Thanks!
Happy to help!
I just used anchors on mine, why not...
If the current thermostat wire is not tacked down inside the wall, just tape up a new thermo cable and pull it through. To me it would of been easier to just run a new thermo cable and do away with that kit. First benefit would new wires and secondly, not adding in a new piece of equipment that can fail.
Yes if it’s easier obviously that’s the route to go but so many are racked in place and you can’t do that without doing a ton of drywall work. Not to mention if it goes downstairs through a finished basement. That’s a nightmare job. This is an easy and cheap alternative.
@@diyhvacguythanks for the video. Yeah guys come on and comment on someone else's video like they know what they're doing but like you said. Everyone can't add wires without having to do drywall work
@@rjdatdude23 Yeah but drywall is specifically designed to be repairable. That’s the whole idea with the stuff. I’m running a new cable.
What do I do for two zones that needs add a wire?
So I have 4 wires they are 2 red 2 white, labeled G, W. Y, RH, WANT TO ADD C WIRE, i have lennox G64 so I would put new wire to C and use G wire to connect the unit for furnace. I DO NOT have cooling system . Please help.
Mind blown! So this device isn't magic? It highjack's the heat wire to bring common 24v when the HVAC is set to "cool" and the cool wire when HVAC is set to heat, allowing a smart, or simply lighted thermostat? Genius!
Exactly
Yes this can be used for a any thermostat I should have made that clear. Not just smart t stats. Cheers
Can you use this with if you only have a 2 wire thermostat?
Nm found it.
Will this work the same if my outdoor unit is also a heat pump
There is a different configuration for heat pump wiring on the slip that comes with the add a wire kit, yes it will work with heat pumps.
Is there anyway this will work on hydronic baseboard heating with a zone valve, it does have the honeywell syncron motor
Not sure on this. I don’t work with baseboard heat boiler systems
@@diyhvacguy update!! Figured it out on an ecobee premium stat.. thanks anyways!!
U can’t just run the blower on its own anymore though right?
I only have 2 wires for my t stat.. i tried ecobee. No power. Any suggestions?
You can replace that wire to the new one with one has 5 wires
I can not find your Amazon page
My AC motherboard doesn't have a C connector on it. What is it I need to do to add a smart thermostat to My house?
I have a friend that is disabled; poor motor control. He’d like to control his wall heater via computer/wifi. Unfortunately his wall heater requires a 750 mW thermostat. Ecobee seems to hint it’s possible, but I’ve yet to see anyone do that. Do you have any ideas?
Thanks for the correction. I’m a novice trying to solve a problem.
I’ve seen another video where they use a 24 Volt adapter as the power source sold by the Nest manufacturer. Do you think that might work. I’ll do some more research.
Screw smart thermostats ,you'll regret it when power Co set it for u and lock u out
Absolutely. I love my programmable thermostat that I installed 10 years or so ago. Suits me perfectly. The less I own that needs to connect to the internet the better.
Can a gas pilot light ignition be converted to a electric ignition?
Probably too much hassle for what it’s worth. I mean anything can be done but the board would need to be replaced as well as the ignition components, probably the gas valve too.
@@diyhvacguy Thanks for the input. I wasn't too hopeful, but thought I would ask since I'm no expert on the subject. Merry Christmas.🎅🎄
I got a Sensei smart thermostat by Emerson instead, it does not require a C wire
So what I’m seeing is you are loosing your continuous fan option unless there is a call for cool?
No, that is another option but this option allows you to still have fan control. You are just using green for the diode, then the transmitter controls the fan. Hopefully that made sense.
My furnace has no A/C and a 2-wire thermostat wire. My NEST works w/o a C wire because I have power on one of my 2 wires. I lucked out, I guess.
Cool. Some of the nests will work without a c but I’ve found that it’s always better to have a c wire. But I’m glad it’s working for you!
Careful, mine ran without a C wire also but shorted out my main board twice over the years. I just hooked up the google C wire adapter and the heater runs way better with it on. Worth the $25 for the piece of mind
You're teaching the castemer everything why you're in trade like a technical go like a teacher?!
I've installed hundreds of stats, never used a drywall anchor, always just the screw, carefully. Never had a problem
As soon as someone goes to yank the cover off to replace the battery’s or reset a smart thermostat you will for sure have a problem.
The screw won't hold steady when you're using your thermostat as an anchor point for pulling teeth!
as a homeowner, I hate sloppy stuff like this. do it properly and do it once. otherwise, its just another annoying technician I have to walk behind and fix their shit
But if you have all the wires already why not just connect the wires directly
If you have all the wires, would you be watching this video about adding a wire? Haha
I’m all seriousness, yes if you have the wires, the adapter is t needed. Something they are hidden or wrapped around the wire loom further back, so check that first. I thought that was very obvious but I need to hit ever base on future videos. Cheers, Dave
I think what it would’ve been easier. The whole time would’ve been just buy a new thermostat wiring that has a fifth wire and just tape it up to the old thermostat wiring and just fish it through the wall and take it back down to the furnace so you don’t have to go through all this Nonsense
DO NOT get a Smart Thermostat, once you do you gave control of your Thermostat to your Energy service provider. Research it for yourself.
No worries just delete the wifi information and they are not connected. Use your phone also as a Hotspot i do and still use Alexa etc when I turn the Hotspot on. Then turn it right back off
Mine was an opt in system, the thermostat for super cheap through the company. I also get rebates being a part of the program. They give plenty of notice about when they will adjust your temperature and limit it to like 20 times a year or something like that.
No, you don’t. Research it for yourself.
This isn't true. That happened where the energy company themselves provided smart thermostats to customers if they opted in to the program. Some you can buy may have the ability to connect to your electric company if you opt in. Not required but they may offer a discount if you do. My provider isn't that high tech anyway.
