How to Install ANY Smart Thermostat | No "C" Wire | Detailed Version

[@bretforeman751]

Dude, you saved me tons of $. This is the only video I could find where the furnace simply had wire nut connections, not a terminal board.

[@jeremiesuire6111]

Dude didn't even install "Any Thermostat without a C-Wire" Great job bro you succeeded in showing people how to do absolutely nothing besides hoping they are lucky enough to have a C-Wire already hiding in theor wall.

[@DeaninItYourself]

That was the purpose of the video. A lot of the times the c wire is there people just dont realize it.

This video saved me from returning my new ecobee because my C wire was not connected but wrapped around the wire and my air handler had no circuit board. Thanks, a lot.

[@charliewyatt4410]

same! I was looking at buying a separate transformer but was worried about how all that connected... Great Video!

[@Indigenous_Patriot_1175]

This video just helped me tremendously!!! Thanks so much for sharing. I thought I was going to have to run a “C” wire . After watching you video and checking my HVAC system , I discovered that “C” wire is already in place.

Best video out there!! Could not figure out how to install my thermostat until I watched your video. Thank you very much!

I just clicked because The Rock is teaching me how to install my thermostat. Hey Rock, Ioved your last movie! Can you put me in as an extra in the next Jumanji flick?...

[@DeaninItYourself]

send me your name and address and Ill get you in. LOL

[@mathew729]

This video saved my life! I was pulling my hair out trying to figure out how to get a C wire connection to our new ecobee3 lite. We have an older furnace with no C connection point. We had the unconnected extra wire and the trick to connect it up to the opposite wire as the yellow coming in from the a/c condenser was gold. My furnace controller board only had R W G so no C connection on the board. I thought I was out of luck. Worked like a charm! Thank you so much!!

Thanks! This got my wyze thermostat going! Used the unused blue wire for the C wire and connected to the correct one on the wire to my compressor.

[@DeaninItYourself]

Glad it helped

[@catsmeow5566]

Thank you for this. I like that you had the C in black over the part on the thermostat. I did notice the "C wire optional with batteries" on the plastic below. I will add that you should always use a voltage detector before touching anything to make sure everything is off. Because sometimes there is a hidden supply of electricity going into things. I don't have drywall- the people who built this place used 1/8" wood panels. I can see that they just poked a hole through for the wires. My Trane thermostat has 7 wires. Red black, white, off white, yellow, orange, and blue.

Finally someone knows there stuff 👍🏾

[@DeaninItYourself]

thnak you

[@porthos221]

hello! thanks so much, it really help me to install an Amazon thermostat. beware that even if you have the blue wire, connected in your old thermostat, it may be unplugged in the main unit. Just follow the instructions in the video and it will get fixed.!!! Thanks again.

[@kevamor]

Man this video really helped me out. I just got a new wifi thermostat never needed the c wire before tested up at the thermostat from the red and c wire saw 20acv so I thought my c wire was hooked up by thermostat wouldn't work after hours of trouble shooting I find the c wire wasn't hooked at at furnace at all, crazy I still was seeing that 20acv but got it hooked up then of course the thermostat then worked. Uhgg. But this video is what made me go double check that the c wire was hooked up. Thanks

[@brucecheek3472]

Thanks for this video.. Helped confirm my thoughts about installing a new 'smart' thermostat. One question, I do not have AC and therefor I do not have a compressor. I do have the blue wire from the thermostat to the furnace but do not know where to connect the blue at the furnace. I have located the 24V transformer but uncertain where to connect the blue wire. suggestion?

[@DeaninItYourself]

one wire connects to the red wire on your themostat, the other one is where you want to connect the blue

[@kevinriggs8326]

Great video, but I have 5 wires going outside to my compressor. Red, white, yellow, brown, and orange. Any idea how to figure out which one to connect the unused C-wire to in that case?

[@Bojangles_supreme]

THANK YOU A MILLION TIMES

[@cutekitten9856]

Totally useless and misleading. You actually do have c wire, so there is no problem to begin with.

[@joe_DWilson]

total loser. clickbait for a thermostat video??

[@sambadeuneaux]

This video helped me in learning the wire to the compressor could be substituted for 24v needed from a dedicated c wire output. It sounds like you have the same wiring I had in my system. Without a c wire, a new 5 conductor wire would need to be run in place of the existing 4 conductor wire. It can be bought at Home Depot by the foot, then connect hour new t-stat per the instructions. If the wire is stuck in the wall you might be better off making a new hole closer to the unit and doing some sheet rock repair. Otherwise a c-wire adaptor can be used which allows the 5 wire signaling to be controlled with 4 wires from your new t-stat but they are way more difficult to make use of if your system doesn't have a dedicated c-wire output from a control board. So tag, you're it! Now it's your turn to share knowledge when you see a problem you can help with.

[@cutekitten9856]

​@@sambadeuneaux I was able to run a 5 conductor wire (actually 8 conductor) for one of my zones/thermostats, but not for the other - it was too far away from the furnace and the old wire was stuck and could not be pulled. But I was able to solve the problem anyway. All you need is a 24 Volt Transformer - exact same you use for your doorbell chime. It can supply power to the thermostat and thus act as a c-wire replacement.

[@kabbythedog9409]

Thanks cat

[@Jack-j3l7o]

​@cutekitten9856 Genius! So simple and so obvious...I never even thought of it. 24v doorbell transformer. OF COURSE! Thank you.

[@stevenyoung190]

Good Video but can you just use a jumper wire from RC to C on the ecobee? that way, you do not need to go to the furnace?

[@williammatthias4841]

Great video, Spot on. I installed a Honeywell RTH6500WF works great.

[@DeaninItYourself]

Great to hear!

[@RoyceRevlon]

I’m missing a part or something I’m not understanding wheee to connect the other end of c wire

[@chathammkm]

Thank you for this video. I got some new basic Nest thermostats and the batteries are draining way too fast in them. We had some old Honeywell thermostats with an LCD screen and I'm thinking that maybe the C wire was not even necessary for those thermostats even though it was connected. I'm thinking that I need to remove the cover from the air handler and make sure that that blue wire is actually connected inside my air handler. I'm hoping that it's not connected in the air handler and that connecting it will solve my battery drainage issue. Apparently this is a common problem that nest owners have and Google doesn't seem to be able to answer the question so I'm hoping that this solves my issue and others if they see this post and your video.

[@limeallens6160]

So you have to have the backing plate for connection? You can’t just wire directly to thermostat?

Everyone seems to have a C terminal on furnace control. I need to know if there is no C terminal on the furnace control what to do. To be accurate I have a very old (45+ year) boiler baseboard hot water heat only setup with only 2 wires at the thermostat.

[@DeaninItYourself]

whoever connected it just used the blue and yellow wire opposite. Thats why its important to take a pic of the before installation so you can put it back like it was.

[@jonathanamador9822]

I couldn't figure out why I wasnt getting power until this video. I just had to connect the inside C wire to the outside wire. Everything was already connect to the board so I was confused. Thank you

[@DeaninItYourself]

Sorry to hear that

[@jfrog180000]

Now here's my issue I have a rezner gas heater in my shop. The board does not have a common wire connection option.. is there anything else I can use to supply 24 volts to the smart thermostat I'm trying to hook up as there is no common connection capabilities on the control board on my gas heater. I know I have an option to install a small rectifier to the main power coming in to step it down to 24 volts to supply the thermostat but I can't remember if there's something else in a furnace that does not have a common option on the control board that can supply the T stat at no more than 24 volts?

[@canuckman4971]

I just checked and I have the same wiring. Our A/C tech gave us an a/c cover for the winter but said to shut off power to a/c so it won't accidentally start with cover on in the spring. Does this stop me from using your example?

[@jimbauer5560]

What happens if you don’t have a compressor outside and need to us an adapter? Where does the blue wire hook up inside the furnace?

[@titoraiz4878]

Thanks for the video. This is exactly what I have. But what if I don't want to do the trouble connecting the C wire becuase our AC unit is in the atic, could I just use an external 24volt from Amazon? The external 24v has two wires, where shall I connect them into the thermostat, C and what else? All other wires (G, W, Y, R) are in exact connections like in the video, including the jumper. Thanks in advance.

[@lbohen]

I have red, green, and white wires coming from the wall. The green wire is not connected to my Honeywell analog (old) thermostat. The red and white wires are connected to the thermostat. The thermostat operates a heat-only propane boiler. No AC. Is there an Ecobee thermostat that is for heat only where I just need the red and white wires?

[@DeaninItYourself]

if you only need heat, you only need to connect the red and white wire, any thermostat will work

[@DeaninItYourself]

what do you mean?

[@nicholasschuller4765]

The Blue wire carries 24v AC. C stands for Cyan(blue. think printer ink) not common. Its the hot wire to power any thermostat so that it doesn't need batteries.

[@armsofzeus]

Are there any smart thermostats put there that support wired sensors? I almost bought the Amazon one but found out it's incompatible because of my sensors.

[@DeaninItYourself]

What kind of sensors? I think the ecobee does support some

[@armsofzeus]

@DeaninItYourself The outdoor sensors that provide temperature readings to the thermostat. I think I found some posts that say I don't have to connect them since smart thermostats pull info from the internet. I just hope I connect the other wires correctly since the labels are a little different from the Amazon thermostat.

Where is my air handler located? In my water heater or ac unit?

[@michaelbarber5651]

I had this working on a Honeywell T6 Pro but as soon as the power was disconnected to change the filter, it stopped working. I had to go back to my old 4 wire thermostat that has no blue wire. Blue wire on opposite 2 wires to compressor and the board actually is labeled "C". I tried disconnecting the blue write on T6 and use only 4 wires but it didn't work. When I look at the Thermostat with the T6 equipment & blue wire, it says "standby waiting". I waited for 10 mins., but no change. Meanwhile the thermostat is blinking "Cool On" which means it is sending the signal but nothing is happening. Everything worked great with the 23 yr old Trane Thermostat the second I connected it.

[@JoanneUng]

Hi, I have an old thermostat using a battery, and now the wires are red, green, blue, and white.. I don't have the yellow color wire. Is it okay if I install the smart thermostat without yellow wire?

[@DeaninItYourself]

Sounds like they used the blue instead of the yellow. Peel back more of the wire and see if the yellow wire is in there. If it is you need to follow my video and switch the blue and yellow wire inside the air handler first.

[@battime5418]

It seems to me that if the Yellow from the thermostat is connected to the transformer and contactor at the same time that the contactor will have power at all time and therefore the compressor will be on at all times. The yellow from the thermostat will not be a signal to activate the magnetic coil within the contactor. I make this observation because you are stating to connect the blue to the other side of the coil contactor. I am not being a wise ass. I truly want to understand and know where the blue should be connected, if the yellow at the airhandler does not have the transformer connected together with the yellow of the thermostat and the contactor coil line. It seem the other side of the contactor coil is the common you want to be tied into the additional blue wire; and if I follow you correctly, then the blue wire will not have power to turn on the nest thermostat. Where did I go wrong in my analysis? Eager for some insight from a tech, I am still green behind the ears when it comes to HVAC. But willing to learn. Thank you for your time. RCB
