I have worked for Siemens for almost a year and have learned more in this one video than I have almost all year. Good thing I was familiar with terminology and how things works/are. This is a outstanding video. 👍🏻👏🏻🤙🏻
This is one of the most comprehensive instructional videos on how a control system works in an HVAC system. Thank you for sharing your knowledge in easy-to-understand concepts of a very vast and complex subject.
This is the perfect intro to have before taking a PLC course. It's important to understand what you're attempting to achieve before programming anything. Thank you, MEP Academy.
Yes, ASHRAE publishes a book titled "ASHRAE Guideline 36: High-Performance Sequences of Operation for HVAC Systems." This guideline provides standardized sequences of control for HVAC systems, focusing on improving energy efficiency, indoor air quality, and overall system performance in buildings.
I remember on a building automation project, i heard stories from an external mechanic working on a rooftop unit complaining about "why everything nowadays must be so complicated", referencing to an electrical duct heater that was supposed to have a modulating SCR on it instead of an on-off relay. First, I heard that this guy was terrible at its job and second, the reasons why are as explained here haha.

Yes of course. you could checkout Niagara Frame work by Tridium. they have a dog and drop feature with their visual programming tool called Niagara Workbench. Another example is the EasyIO line of controllers.
Correct, as it demonstrates the variability of solutions. Those in the controls industry know that there are ways to do things inexpensively, or with additional layers of controllability that add cost.
I have a question, My church has canvas ducting for the heat and air and is suspended from the ceiling. It seems to have a wire structure to support it... Im guessing... What is the proper name for that type of duct work? The registers are cut like a C shape that closes when its not running. I really appreciate any help
There is no one simple answers as it is based on your application and the facility requirements. Controlling for air flow or CFM can be useful in constant volume application, while controlling for pressure can be useful in VAV applications by adjusting the fan speed with the use of a VFD. There may be critical applications that require that the Air Volume be maintained (Airflow based) and the fan speed is adjusted to maintain that CFM. In a VAV system, the pressure differential is closely related to the airflow. As the demand for conditioned air in the various zones changes, the pressure differential adjusts accordingly. Pressure-based control with a VFD allows the fan to operate at variable speeds, optimizing energy efficiency. The fan speed is increased or decreased as needed, reducing energy consumption during periods of lower demand.
If you're not already in the trade, then going to vocational school is a good start, or starting as an intern at a controls company if you have some mechanical background. If you have any form of a college degree or work history, then apply to control companies in your area, they are always looking for good people. Check your local college or vocational school for classes related to the HVAC industry or Building Automation Systems. Also, check all of the top control manufacturers websites for free training or certifications that could get you up to speed on the latest technology. Good Luck.
Shout out to this instructor for talking slowly and making it easy to comprehend information. 🔥
Thanks Paul

Thanks Garrett
Can we have a quick call
Sounds about right, Siemens sucks with training and bringing their own people up.

Thank you
Simply great, I couldn't expect a more complete and well-explained content! Thank you from an italian Engineer
You are welcome!
This is the perfect intro to have before taking a PLC course. It's important to understand what you're attempting to achieve before programming anything. Thank you, MEP Academy.
You're welcome. Thanks for watching.
i’m a mep estimator in training fresh out of my bachelor is construction science and this is helping a ton! thank you
You're welcome. Thanks for watching.
Excellent explanation. Can you make a video on calculating the pump head for the central cooling system? Thank you
Have you watched our other video on Pumps. ruclips.net/video/paziP4GdYio/видео.html
Very clear and well presented. Very helpful for an engineer.
Glad it was helpful!
Every one of the video posted in this channel provides great knowledge on BMS . Very easy to understand as well . Thank you for the knowledge 🙏
Thank You
Thank you
THANK YOU FOR YOUR GOOD EDUCATION, REALLY HELPED ME LOT TO UNDERSTAND THE PROCESS OF HVAC.
Glad it helped. Thanks for watching.
Great instructional hvac electrical control video
Glad you enjoyed it. Thanks for watching.
What a great video. Thank you for teaching the new techs coming up in our industry.
Thank you
Very informative and easy explanation ... please make videos on what sort of energy saving measures we perform on HVAC system during energy audit
Thanks. We'll consider adding that topic to our schedule.
Very easy to understand. Thanks for your videos
You're welcome
Nice great for understanding
Thanks for liking
Please discuss on part winding cannection star and delta cannection.
Thanks for the suggestion.
Amazing video
Thanks for watching.
Is there a comprehensive library of common control Sequence Of Operations out there anywhere?
Yes, ASHRAE publishes a book titled "ASHRAE Guideline 36: High-Performance Sequences of Operation for HVAC Systems." This guideline provides standardized sequences of control for HVAC systems, focusing on improving energy efficiency, indoor air quality, and overall system performance in buildings.
Thanks, very good explanation, please make more such vedioes very helpful
Thanks
Great presantation...
Thank you
@15:39 I'm sure he meant 4-20 mA, not 40-20 mA
Great videos btw!
Good catch. The subtitles had it right, but the reader misread the transcript. Thanks for watching.

Thanks for the comment, and for watching.
good .... keep up the good work dear
Thank You

Is there a program where I can click and drag blocks to form a sequence of operations?
Yes of course. you could checkout Niagara Frame work by Tridium. they have a dog and drop feature with their visual programming tool called Niagara Workbench. Another example is the EasyIO line of controllers.
Drag and drop
In 20 min we went from a $0.50 switch to a $25k system just to turn a fan on off.
Correct, as it demonstrates the variability of solutions. Those in the controls industry know that there are ways to do things inexpensively, or with additional layers of controllability that add cost.
Actually not a good idea to turn a fan completely off.
Blablablba.... read a book!
Energy managers need to be able to control that switch to save money. They will never recoup their initial investment but they can justify their job.

We believe you're talking about DuctSox or a similar brand. Here is their website. Let us know if this what you're looking for. www.ductsox.com
@@MEPAcademy Awesome Thank you sir! I appreciate yall!
@@MikeWhiskey427 You're welcome.

not very finishent? do you mean efficient? 3:22
Yeah, the subtitles got it right, but the speech is a little slurred. Should have used AI. Thanks for watching.
Are these courses for hvac control automation can some one tell me how to get into hvac autimation control
