Hey Mike, clever how you put this together, showing what controls voltage flowing where and when. Keep em coming....
A picture (video) is worth a thousand words. Another educational and informative video.
Thank you
Thanks Jersey Mike! This was a better example than my junior college hvac class. We used the slides taken from photos in the book. This was way better.
Glad it was helpful!
Dude your fucking videos of how to do this shit is beyond brilliant keep up the good work
More brilliant shit to come! Ha.
Excellent video. I really like the animation with your expert commentary. You have a knack for explaining complicated scenarios so they are much easier to understand. It’s a huge amount of work to put this together. Well done.
Thank you very much!
Great visualization for a newbie! Much obliged, sir!
Well done! Best Through description of the thermostat wiring
Thanks a lot. Very useful and clear explanation. Great service to the community.
Thank you so much for this video 🙏🏿You don’t understand how much time this saved me.
No problem. Glad it was helpful for you.
This is great! Thank you for making this video!
My pleasure
Another great video!
very effective method to train. I am sure that help a lot of people
The smart thermostats I've used give you the option of whether or not to energize the green wire when turning on the furnace. If the green wire is energized, the blower will turn on immediately. If it's set to let the furnace do it (don't energize the green wire), then the furnace will go through its startup routine and the control board on the furnace will energize the blower motor once the startup routine is finished. The 2nd option is the more common setting. Older, non-programable thermostats, including mechanical thermostats, used the 2nd method by default.
Is there a standard default setting on that or will it adjust according to system set up? I'd imagine that "activate" option is for electric furnaces. Curious if it defaults to "activate" with electric furnaces and defaults to "not activate" on oil/gas. Or does it always have to be done manually?
@@JerseyMikeHVAC I've been using Honeywell thermostats and their default for heat is to let the furnace turn the fan on, but it is configurable. However, this was also the way old mechanical thermostats worked (the ones with the glass tube of mercury).
your videos are on another level. Thank You!
Very Welcome.
wow! excellent video love it thank you
Glad you enjoyed it
Excellent
Thanks a lot. Thanks your content i was able to figure how to wire a rib relay to a nest thermostat and zone valve.
Glad I could help
Great video
Thanks!
Can you pls do a video about mini split troubleshooting not too many out there
Easy to understand. Thx 🙏 much
Superb visual thank you for your work.
Thank you.
Thanks for a great video Mike, love the channel!
Very welcome
Thanks Jersey Mike, valuable info 👍
You bet
EXELENT
Is a little bit more complicated when you have pressure switches but nice job
Nice job Mike!...learned alot 💯
Glad to hear it
JM, this is awesome. thnx for putting it out there. Hoping to see a similar set up for the heat pump system with electric heat strips.
Definately
You know, after all the issues, stress, that i was bothering you, and every one else out there, with my outdoor unit not starting up in heat nor cold mode??? I decided to go and check for myself, to see if I could see anything for my self that maybe the cause. AAANNNNDDDD....GUESS WHAT? I touched one of the wires that goes to the COIL OF THE CONTACTOR, and the darn thing CAME OFF in my hand. All these yrs, and THE MECHANICS who installed this unit DID NOT HOOKED THE WIRE ON PROPERLY TO THE CONTACTOR. It must have been touching somehow, thru the yrs, passed, because the unit was working ok, until recently. I connected back the wire PROPERLY, to the COIL, and put the thermostat to call for heat, and BOOM!!!!!, IT WORKS like a CHARM. Maannnn!!!!. I am happy. All is good now. But I really appreciate YOU Sir. Thnx a million for ur help. i HAVE LEARNED A LOT, these couple of days, AND I DID NOT LOOSE ANY MONEY. One guy in my area, when I called was asking $195.00 to come out to diagnosed the unit. WHAT A BUNCH OF RIP OFFS, they have here in ORLANDO. BUT, they did not get me. I am moving back to NEW YORK. Where the good old REAL AMERICANS ARE. THAT CARES ABOUT THE AMERICAN LABELING. Because these FOREIGNERS DOWN here that called themselves AMERICANS, are a BUNCH OF FAKES AND SCAMMERS. Now I know WHY a certain ONE TIME leader of the FREE WORLD, has his holdings in this state. IT IS WHAT, IT IS. But, GOD Bless YOU Sir, and may God still BLESS AMERICA. @@JerseyMikeHVAC
oki, dude. is there anyway you, (or any one else) could explain how the "common" and the "ground" is the same in a 24v circuitry. Or how is the common grounded, or where? Thnx.@@JerseyMikeHVAC
The unit itself is grounded through the high voltage back to the electrical panel. The low voltage ground just gives a path for the power to follow in the case of a ground fault/short.
Some older systems terminated low voltage circuits on the unit chassis rather than on a common terminal. A lot of furnaces used to do this with the burner circuit.
Great
Great 👍
Thanks Mike
You are welcome!
Nice, nice!
Thanks!
That’s some high shit presentation bro thank you
Thanks..... Thanks
Can you do a diagram for a gas steam boiler?
Absolutely
@JerseyMikeHVAC what is your image video platform used for this video? Hope to get from you
I just used Filmora video editor for it, but I'm trying to learn my way around Blender so I can move over to that eventually.
Do you plan to do private lessons?
Trying my best to find the time to start doing that soon.
Its BANG
👍
May I have your contact info please
I don’t see the capacitor
It is not a relay or control system
Great video
Thanks!
