HVAC Thermostat Wire

[@MrCornbread1981]

Dr . Z !!! i started attending the institute of technology in Stockton , Ca for HVAC almost a month ago ! i want you to know my instructor shows your videos mostly everyday ! i want to thank you for the time and effort you take to making these videos , THEY ARE A HUGE HELP TO US ALL !!! Thanks Dr. Z !!!

[@pelonely100]

works fine, the only thing, it runs for 5 min. after the temp.is reached,,,thank you again for all info.you put here.

[@Mowers11]

DR, I have been doing the stat wire stripping for years. Thank you. !!!!!

On a unit that takes in fresh outdoor air, and exhausts indoor air, and energy wheel rotates like a spinning disk with the fresh outdoor air coming towards you through the top half, and the indoor air is flowing away from you through the bottom half. The energy wheel grabs heat and humidity from the outdoor air, then rotates around and puts it into the outgoing exhaust air. It preconditions the air using only the power of the motor to make it rotate. AKA: "heat wheel" or "enthalpy wheel"

[@Zanbor59]

Thank you Jim for your education......GREAT VIDEO

[@benzie8352]

Thank you so much for this informative video!! Extremely helpful 🙏

[@DrZarkloff]

Thank you for watching

I found this problem with a set of wires with a lineset run under a beautiful patio. They spliced it somewhere under the patio. I needed a yellow and didn't have any. I ended up running about 50 ft of 5 wire around the foundation of the house and garage as the patio was not moving. I don't know if the customer ever had any problems with the lineset but I told him he might in the future. The patio was cement and marble, heavy and settling.

[@stuartewoldt1513]

Aaon are the ones with the energy wheel or you can get a little separate unit to install into your system. They're pretty cool

[@DrZarkloff]

@2jlrivas The thermostat wire should go from the air handler to the condensing unit to control voltage to the compressor contactor and/or the defrost board.

[@DrZarkloff]

@hvacjourneyman You don't always need the amount of wires that are in the bundle. It's okay to cap off the ones that you don't need. You never know when you'll need them sometime in the future.

[@mike111777]

Thank you Dr. Z. Your videos have been helpful.

[@More350Power]

It is scary what you find in walls.... Ive found splices on a 50 amp stove circuit, laying on heating ducts waiting for someone to touch it and either get knocked or have it short to the duct and flash....

[@DrZarkloff]

Thanks. No two techs think alike.

[@tymr.t3645]

Thank you so much champ 👍 Needed that 🤗

[@DrZarkloff]

Thanks. I'm glad that my videos help many people.

[@flashmonkey9179]

DrZarkloff. I was weed eating and accidentally yanked a wire out of Ac unit theres a white and red wire with copper tips not wired copper tips the wire looks like its going underground into house. My fan ac unit isnt coming on but my thermostat thermostat is on and working but no air plz help can i fix this if so how? Thanks

[@Dachamp2001]

I need to upgrade to the 5 wire from a 4 wire 😩 I upgraded the thermostat to a smart thermostat and its recommended to use the blue or C wire. But I'm in a old house so the wires is ran through the return in the basement. I forgot old houses they make returns through the rafters rather then duct work smh

[@pullingthestrings5233]

Dr i recently installed a new 5 ton unit and it seems to never cool below 81 degrees. Do you think their can be a problem with the thermostat wiring? Thanks

[@zlee11]

Very informative. Thank you

[@DrZarkloff]

@KingRhaul I don't do much gas furnace work.

[@2jlrivas]

I ran into a condenser that the thermostat was not wired to it. Where do the wires from the thermostat go. The only place I could see was terminal on the contacts. Could give me some insight on this situation. The thermostat wires are coming from the a/c unit (furnace) inside this trailerhouse. Thanks

[@DrZarkloff]

Thanks for watching. I'll get around to that video sooner or later.

[@MariaJimenez-nu8vc]

how you install the wires out at the board

[@hvacjourneyman]

Thank You Sir, seems like I run into a lot of heat pumps with only five wires to the Thermostat, and find the rest of the wires taped off or capped. Why do people do this.

[@bobbydigital8]

I haven't checked yet, but do you have any videos on how to wire low and high voltage to a furnace and blower ac unit.

[@raleh1]

Please explain how splice the wire

[@KingRhaul]

got a question..i'm installing a goodman variable speed 95% furnace,2 stage gas valve and the blower can be set to blow from 600 to 12 cfm...the homeowner will eventually build an addition to the house but right now the house will need barely 600 cfm's, i was thinking gas valve on first stage and blower on the lowest setting but i was told that i may need to lower the gas pressure if running on low cfm which makes sense but i wanna know how do you figure out the proper gas pressure then?

[@mikie2501]

lol, learn something new every day! I would have never thought of using that to slice the jacket open, just assumed it was to give strength to the set for pulling. lol. Thanks ole man :> M@

[@DrZarkloff]

It's an energy saving device. I do plan to talk about them in a future video.

[@bobbydigital8]

Question, is there a wire running from the thermostat to the furnace and blower. And a separate wire running from the condenser unit outside to the furnace inside? If not help me understand please. (straight ac unit not a heat pump)

[@YearZeroHero]

My wire system has: O, W, G, R, Y, 4 We have oil and a wood burning furnace separate . The thermostat i am trying to install has B, O, Y, W, G, R, Rc...the wire running between 4 and R was on the old thermo, but it only ran between those two...now there is no hot air blowing...for the love of god

[@DrZarkloff]

@36carlosphillips1 Thanks for watching and keep the interest.

[@pelonely100]

1) DR.Z I HOPE THAT YOU CAN HELP ME OUT,I REPLACED MY THEROMSTAT BECAUSE WHEN THE TEMP.IN THE ROOM WAS REACHED THE UNIT CONTINUE TO RUN FOR ABOUT 5 MIN.AND THEN STOP.WITH THE NEW ONE IS STILL DOING THE SAME THING,RUNING ABOUT 5 MIN.

[@mman454]

what is an energy wheel?

[@DrZarkloff]

Thanks. Yeah a j box can be a decent place for a spice.

[@DrZarkloff]

Thanks. I seem to find a lot of these splices lately.

[@DrZarkloff]

Yes. You got it right.

[@atiqsmail]

I was trying to install a new 5 wires thermostat replacing an old 4 wires. I used extra wire as c wire but the furnace terminal board side already has a wires attached to it(C and Y), which runs to out side compressor unit. when I attached the new run c wire to this c terminal it is blowing out my 3 amp fuse. where should I connect the c wire of the new thermostat then?

[@drzarkloff506]

it sounds like the wire that you're connecting to C terminal on the stat is connected to something else in the air handler.

[@67tr876]

great vid man !

[@DrZarkloff]

Thanks for watching.

[@ishchaiwahiythay1291]

dr z, why does my thermostat have a jumper wire

[@DrZarkloff]

That's common especially with digital t-stats.

[@bobbydigital8]

Simple and useful info,thanks.

[@aarongray503]

Thank you.

[@good_commentary5829]

Man you did that the hard way

[@DrZarkloff]

Thanks as always.

[@Scrat335]

Correction. I don't know if it was spliced. I never bothered to take the old wire out.

[@royalken949]

Good info

[@occfan2008]

great video

[@DrZarkloff]

Thanks.

[@DrZarkloff]

Thanks

[@DrZarkloff]

I've actually tried the free dental floss. It tends to get stuck between the teeth. lol

[@DrZarkloff]

Yes.

[@jimbola77]

nice DR Z!!!!!!

[@DrZarkloff]

Thanks. That must have been a big box of wire. lol

[@V8Jagnut]

cool vid. that was a very messy splice.lol

[@DrZarkloff]

It sounds like it should work.

[@DrZarkloff]

I hope that you left your card with the home-owner so that you could go back.

[@john67elco]

Wow I fail at life. That's what the damn strings for!

[@DrZarkloff]

At least I'm lot the only one finding these little hack jobs. lol

[@Jeff82556]

Although I appreciate your video, it was amazing that you probably said "uh" or "um" 80-100 times.

[@drzarkloff506]

Uh thanks for watching. I usually edit out the pauses and the "uh" moments.

[@Jeff82556]

@@drzarkloff506 Lol.... you could never edit out your uhs and ums. That would delete a huge 30% chunk of your video. Be well...... Besides, there's nothing wrong with uhs and ums. Many people can't help it, just like my brother can't speak without waving his arms and hands like a conductor in front of an orchestra.

[@DrZarkloff]

It's strange how this is seldom taught in school.

Thanks for watching.
