⁠​⁠@@diyhvacguy❤❤❤❤❤❤❤❤❤ a couple days ago. I misunderstood ? somebody who had a really nice voice. They sold me a printer….. I said “does it have toner” and what I meant was does it have 100% toner loaded in it. The person said hey, we were able to print with it. When I got home, I found out all the color cartridges were low and the black cartridge was less than 10% full. That was a store called action computer.

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.

[@hvacworkshop4791]

@@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.

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!!!!

i have a two wire (red & white) for baseboard heating only What can I use to add a C wire for a google nest thermostat

[@saltedxp]

I just bought the Honeywell c-wire adapter for the furnace. Works perfect and DIY EAZY

[@MsMexicanito13]

What is it called

[@gpraceman]

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.

[@tonightsmovieis]

Does this work for an old old old oil furnace that only has two wires, sadly such as mine

[@davidwalker3039]

Thanks this is the best video yet.

[@whspioneer89]

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?

[@tombarnes1871]

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!!

[@diyhvacguy]

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 [e-mail] Cheers

[@AceBoy2099]

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.

[@joeaubert7224]

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.

[@Tonayez]

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 .

[@lukas______]

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

[@datboi8140]

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

[@shortie4track]

This comment saved me!! I dug around a bit and found the blue c wire ! Thank you!!

[@Dyslexiasymtum123]

Dude, you're a hero! You just saved me so much work! 😂🎉

[@timkishelov9489]

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?

[@RGlide514]

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

[@danw2002ti]

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

[@diyhvacguy]

[@filtercharger]

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! 🙏

[@Bmackie731]

How does this differ if I'm swapping out two thermostats, one on each floor? Separate diode for each floor?

[@michaelsheeder148]

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 ☺️

[@diyhvacguy]

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.

[@DonovanRocheleau]

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!

[@timmydee3277]

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.

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.

Super cool. Have been following your videos and been doing what you have shown as far as spare parts and converters. Thanks.

[@briandow8879]

So what I’m seeing is you are loosing your continuous fan option unless there is a call for cool?

[@diyhvacguy]

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.

[@tubeDude48]

At 10:15, I would have used a Wago.

[@TheMinnow101]

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.

[@diyhvacguy]

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.
