[@brettmulligan]

I have been binging these HVAC thermostat wiring videos in prep for installing a smart thermostat, and this is easily the best breakdown of the wiring that I have seen. Thank you!

[@SeriusQne]

LITERALLY why I'm here too

[@504BayouDago]

If you are installing a smart stat make sure you have a common wire! If not, make sure you get a smart stat that doesn’t require a common wire at the thermostat but will have a separate distribution panel that goes on top of the furnace or air handler.

[@gourikk7721]

I agree, i just got my AC to work finally with ecobee thanks to this video.

[@Garth2011]

Most decent thermostats will need that "C" or 5th wire to run them. Battery powered thermostats don't however, batteries leak, they will eventually need replaced at an inconvenient time unless you change them on a schedule, plus the cost over the years. There's really no gain to use a battery powered thermostat unless you want to avoid having to update your home with a 5 conductor thermostat bell wire to the attic or to the furnace. One day, all HVAC systems will require that 5th wire so may as well put it in for the day its needed.

[@atb2003]

I noticed that there has been a device “Google Power Connector” to gain the common wire, I suppose this is short of running that 5th wire up to the Nest thermostat. I think they are creating more of a hassle for people than to just requiring them to run a new cable. Usually the thermostat cable does have a spare wire but once they tell the public to install this Google Power Connector people just follow the instructions. It works but in my opinion it is hacked.

[@stephencaronia9802]

Usually the person presenting skips something that seems so obvious to them but is unknown to the viewers. This was thorough and extremely clear. No information was omitted. Thank you.

This is one of the VERY best videos on HVAC wiring. No BS...straight nuts and bolts for guys...and ladies doing their own repairs. Very informative...will be using this info tomorrow. I have a 5 year old Trane that is an electric heat and A/C package combined w/ 2 240 shutoff panel boxes. It has worked flawless, but now...for some reason it is putting out heat from the vents when the thermostat is on auto and the COMMAND is for cooling.

Love your video I have a question that I hope that you can help me with. I have a large wood burner in my house that I have a stand alone blower on it is 120 volt how can I control the blower with a thermostat this just the blower to circulate the hot air

[@lockeyestlocksmith2349]

Use a Ford starter relay 6070s 80s even 90s. The big post on the relay Will be for your fan motor at 120 V. The thermostat will need a transformer at 24 V that will work with your two smallWire leads on the solenoid. Also wire and a five amp fuse on the thermostat side, you're 120 V circuit is already fusedAt the breaker box.

I never comment and typically don't even browse while I'm logged in BUT I felt compelled to because your video is so good. Seriously - thank you! Thank you for taking the time to make the video, but even more importantly, thank you for being clear, concise and acurate. I went through a ton of trash infomation (some youtube, some HVAC manufacture's videos, countless google & bing articles) and had pretty much gave up. Then I found this - PERFECT intro to how these systems work.

Very well done young man. As an electrical engineer seeking help with understanding the internal workings of a thermostat, you did an excellent job of detailing the contact logic contained within the thermostat and how those contacts ultimately control the external devices, such as the fan, compressor, heat system, etc. Well done, best explanation I have found.

Thanks for your explanation of the thermostat wiring. I'm trying to install a new thermostat and the manufacturer's video was very confusing. I now understand that R-wire is red wire, Y-wire is yellow wire, G-wire is green wire, W-wire is white wire but C-wire is black wire. The C meaning black wasn't explained by the manufacturer. Follow-up: After watching your video, I was able to properly install a new Honeywell thermostat that relied on using the C-wire that had previously been unused. Unfortunately, when I flipped the switch it was dead. I was sure that I had killed my new thermostat and furnace and would need to call the repairman in shame. Before doing this, I decided to open the furnace up. Apparently, whoever installed the furnace never saw your video. For some reason, he had installed the C-wire to the wrong terminal. After correcting his mistake, it works perfectly.

[@acbeaumo]

This really helped me figure out the wiring in my thermostat. Mine had only four wires going to it, and the blue wire was connected to the Y terminal. Looks like when the previous owner had cooling put in, the technician used the common powering the thermostat to control the cooling, instead of running a new wire to the thermostat. The thermostat was using battery power only.

[@bobb.6393]

Saved on copper lol

[@jimjohnson2321]

Thank you for this tutorial. You just saved me a call-out fee and the cost of a contactor . All was good except for the two leads going from the air handler to the outside unit.

[@Howie875]

I like the video but I think I have a few things to add. I believe the senario you gave about the y terminal affecting the speed of the fan might be only on whatever type furnace you are working on because I am not familiar with it. In my experience, the green terminal always energizes the high speed fan ( regardless if the y terminal is energized or not) for cooling or for air circulation alone with the fan switch on the thermostat. The low speed on the fan is actually part of the W terminal operation. On a call for heat, as the burner fires up the furnace delays the operation of the low speed fan until the burner comes on and runs for a minute or two which allows the unit to blow warm air from the start when the fan finally comes on. Low speed fan is used for heating because any type of high speed fan causes a cooling effect, something you do not want on heating operation.

[@Howie875]

@ibrahemnaser2309 Most indoor fan motors have a common wire and also three wires that can be energized by the hot side for low, medium and high speed. Only one can be energized at a time! Most of the time only high and low speed is used with medium being a spare. On a normal furnace you can just exchange the high-speed lead for the medium speed lead at the circuit board or relay. If you know the sequence of the fan operation you can write a program to control all three speeds thru WiFi modules. For the fan in cooling operation, it energizes immediately but runs for a minute or two after the compressor shuts off so it can blow all of the residual cooling effect out of the coils. VERY IMPORTANT - Modern furnaces have several very important safety and limit switches in them. I have seen them bypassed by people who did not understand them, and a system failure could cause a fire without those safeties and limits working properly. Be very careful or do not try any modifications!.

[@unclefreddieDied]

Howie... different question if you feel like answering.. i have a summer/winter change over (which i'm not even sure means). oil burner that has baseboard radiators for heat but no a/c. will a fancy new thermostat like the nest work with this set up?

[@Howie875]

@@unclefreddieDied Not familiar with oil burners or radiators but if your system currently works off of a standard thermostat now it should have no problem working with a nest. All a nest or a standard thermostat does is close an electrical circuit when you need heat. May need to run a common wire from the transformer to the nest to give it a constant 24-volt power to operate. As far as a summer winter changeover, if you have no AC then that would not even apply for your application. Not sure how your system is actually wired so I can't get specific about wiring.

[@unclefreddieDied]

Thanks to you I was able to connect with great certitude the c wire for my new wifi thermostat. I bought 2 smart thermostats a while ago, one for the family room and one for the basement. I installed the one for the family room without a problem. It had all the required wires but I could not do the same for the basement as it did not have the c wire. Today I decided to try again thinking that if there is a c wire upstairs there should be one downstairs and sure enough it was tucked wrapped behind the wall and it wasn't connected in the furnace. After I came across your clear explanations I understood what needed to be done in order to have the c wire connected. Thank you very much, not only did you teach me something but you also saved me some $$ since I was getting ready to go to the big bucks store to get an adapter for the c wire.

Hello Benjamin, your video was very excellently explained with diagrams, video and involved with loads of information and with slow and clear English, great job buddy.

[@edlopez5661]

Thanks. I watched several other videos and your video really made sense to me. You not only connected the heater/thermostat while explaining the air conditioning/thermostat function, you really tied it all together the best possible way. I got my wires all prepped for installation now. I already have the circuit breaker off.

[@rodneyboyer206]

At around 7:37 you state that the thermostat shorts the R to the Y AND the R to the G so the furnace will turn on the fan during a cooling cycle. That is NOT how it works. The thermostat only shorts the R to the Y to let the furnace know there is a call for cooling. The control board on the furnace itself operates the fan. Unless running the fan by itself for ventilation is desired, the G wire does not even need to be connected to the thermostat at all. The heating and the cooling will work just fine if the G terminal is wired or not. There are a lot of people who think they have to purchase an "add-a-wire" module to convert to a 5 wire system to use a smart thermostat if the existing wiring is only a 4 wire system. In actuality, they can disconnect the G terminal on both ends and instead connect it to the C terminal on both ends and the smart thermostat then has the 24 volts and return that it needs to power itself. The furnace and A/C will function normally. The only function that doesn't work is the fan by itself for ventilation which the vast majority of people do not use anyway.

[@keithhults8986]

I installed countless smart thermostats, in place of existing over the years. Your explanations were simple and precise. Very old heat/AC systems might not have a "C" wire available to power the thermo programming. About 30% of my smart thermo installs, require installing an additional cable to produce the "C" connection between the air handler and thermo. For DIY people, Shut the power, I work live. I been doing this 40 years. If you make one mistake on the printed circuit inside the air handler, the 3A fuse will protect printed circuit, but there is a very good chance, you could short a circuit board, then the entire control board inside the blower will need replacing. My helpers caused this problem by not following my detailed instructions
