Teaching Thermostat Functions to New HVAC Techs and Students!

[@antonleimbach648]

This is a great video for anyone who owns a home.

[@paulrozinski1488]

The AC delay function eliminates the need to install a Delay on Make relay at the compressor . Nice !!!! I’ll look for that feature on my next thermostat . Thanks. Again, more great information

[@davetysdal5442]

My new condenser doesn't have a SC delay. This will help...

[@devhammer]

Great explanation and really easy to understand.

[@zahedaminullah6934]

No wonder the COOL ON flashes and flashes. I had no idea the pressures gotta equal. I just thought it was a way to not damage the compressor

[@realSamAndrew]

It **is** a way not to damage the compressor.

[@4kideo]

Great explanation! as always...........The best of the best at teaching HVAC Systems

[@judodavid1]

Thank you for the knowledge

[@michaelnunes84]

Great demonstration so simple

[@user-tr9to2bh6x]

Thank you your Videos important information and easy way

[@deanmartin1966]

Great info. Thanks for sharing.

[@LuisHernandez-yr6yo]

Thanks 👍🏼

[@mrgreenthumb169]

Great information. Learning so much. 👍 Do you have a video about capacitors?

[@Zurp777]

He has a bunch of different capacitor videos, I was going to find one and link it but he has too many xD

[@davidmclain1875]

Great video. I always wondered about the compressor delay. I know with a lot of window units, they manual will tell you to wait 5 minutes after you turn it off before you turn it back on. But I've also been curious about the many videos of techs working on an outdoor coil. Seem like a lot of times, during their testing and diagnosis, they will kick the compressor on and off during a repair or whatever, and they don't always seem to wait 5 minutes between starts. Just curious about that. Thanks,

[@rob0516]

From what ive learned about doing that exact test is to see whether the compressor has the power to pump the system and to see if the valves inside the compressor are not weak or faulty.

[@servant-4-jesus]

Could I test the thermostat for proper function at the furnace or AC unit in the same way ? I would assume yes just wanted to verify Thanks for all the great content

[@johnnychang4233]

Yes, you just unhook those wires shown in the video from the boiler or Air Conditioner side and test the continuity when setting the desired mode 😉

[@servant-4-jesus]

@@johnnychang4233 thanks 👍

[@chrisdeanndavison3626]

Keep in mind, a problem that could arise from testing at the furnace is if there is a broken thermostat wire.

[@servant-4-jesus]

@@chrisdeanndavison3626 thanks 👍 Then I could disconnect the wires and connect 2 together at a time to test continuity. Right ? Or do you know a faster way 🤔 my old boss would have me just run wires from t Stat to furnace but it is a lot of wire sometimes and then I have all these long rolled up pieces of wire on my truck it always seemed like a waste to me 🤯

[@chrisdeanndavison3626]

@@servant-4-jesus I believe you could tie all wires together at once to test continuity. It would save a lot of trips from the basement to the thermostat. Although, if you have damaged insulation (which is not uncommon in a broken wire situation) and wires are touching inside a wall, that wouldn't work either! If that were the case, you'd need to test for continuity with all wires disconnected from each other and also the equipment. If any wires test 0.0 ohms between and they're disconnected from everything, then it's a short. Thermostat wire issues can take a long time to diagnose!

[@davetysdal5442]

I have an old in the round T stat. It seems to be short cycling in HEAT mode. Going to get a new one like above today. And these delays...

[@wahid6725]

educational thank you so much

[@cck1496]

Good video. What is Rc? Thanks.

[@indiantraveller194]

Good sir

[@416RG]

What are those alligator prongs you are using with your multimeter??

[@cck0728]

Good video. Normally for process industry compressors, the suction pressure is never equal to the discharge pressure. But why it is important for HVAC compressor? Thanks.

[@fillmorehillmore8239]

Sure glad I've watched your videos to have the same conclusion that the tech that came into my home did. $450 dollars later and the same parts replaced that I thought. Because they are accredited they get the parts sent under warranty, but if I try?

[@roberts1159]

If your system still has a parts and labor or just parts warranty then you would either pay zero or just labor to install tstat. If I understand your question correctly. If you were to install the tstat cost is totally on you.

[@JerichoStephen]

Hello awesome video 🫡 👌 🙏 Can a tech to make to limit the gas usage in furnace ?

[@raymondlanier1112]

Are you saying fain or fan? This was a great training video

[@ale_9450]

Do you have one for a heat pump setting?

[@muhammadnaeem4834]

Nice

[@randomvidz512]

Can you do some with the field piece sc680

[@thereckchanic4709]

This is also an easy way of testing the thermostat to make sure it’s working properly.

[@airconditioner143]

can you teach us LP HP pressure switch wirings....

[@PosiP]

can you show us how to install a 5 minute time out relay for the compressor and what is the best relay to use. I want it connected to the Line side and if that hasn't been hot for 5 minutes then 24 volts will not make it to the contactor.

[@annaleet]

Don't need Do anything Thermostat Now already have 5 min relay For Start Compressor or outside unit . It's very Safety

[@PosiP]

@@annaleet so if the power reset for 10 seconds to the thermostat it will not call for heat or cooling until its 5-minute timer expires?

[@aajdre6556]

@@PosiP yes that's correct

[@aajdre6556]

I typically don't use the batteries I just use the power through common and red (24v)

[@PosiP]

​@@aajdre6556 so if the Tstat is powered by batteries and the power resets, and you have a call for cooling as the power is reapplied you could get a compressor starting with high pressures. That is the reason I asked about the timer relay. For heat pumps, you could just break the power to the reversing valve to equalize as well. I was asking a question I know the answers to, sorry.

[@sallsouza6789]

How to by pass lowest settings? Cool settings are set for 65, at times I want it to go down to 63.

Why does “R” and “Rc” always have to touch, what is the purpose for “Rc”?

[@HardRockMaster7577]

Sounds just a little slow at 50% playback speed.
