🚨 If you said, "Automatic control? Oh, that headache-inducing stuff?", then come on in! Does just hearing the words "Automatic Control" give you a throbbing headache? Don't worry, that's perfectly normal! LOL. To be honest, I was the same way. Casting my mind back 17 years to my "newbie" days when I didn't know the first thing about automatic control... I suddenly landed a job at a foreign company dealing with factory automation systems. My shallow fantasy of "The company isn't a school, so seniors will kindly spoon-feed me everything~" was shattered spectacularly. Expecting a "kind mentor" from seniors who were losing their souls to a daily deluge of work was a luxury I didn't have. In the end, I had to learn the hard way by digging into thick manuals on my own, grasping concepts one by one through blood, sweat, and tears. The result of enduring and grinding through it all? I grew into a seasoned 18-year veteran engineer who leads HVAC construction and commissioning for major overseas projects like Kuwait Oil Company (KOC), Abu Dhabi National Oil Company (ADNOC), and Saudi Aramco. ✌️ 💡 Take the shortcut with the know-how I gained through trial and error! I poured everything into this course for juniors and seniors who, like me, are full of passion to grow but feel lost on where and how to start. I'll be honest with you. I won't lie and say, "This one course will make you an automatic control master tomorrow!" However, I am confident that once you finish this course, you will have a framework more solid and certain than anyone else's, understanding "Ah, so this is what automatic control is!" and "This is how all the gears mesh together!" 🌐 Regardless of your major, automatic control is now a "must-have survival item"! AI, IoT, autonomous driving, smart factories... the world is changing so fast these days, right? We've entered an era where it's hard to work properly without an understanding of automatic control. • If you're an Electrical Engineer, monitoring systems like EPMS and SCADA are basic setups! • Mechanical Engineers have also become inseparable from control systems like BMS and FMS. • Data Center Engineers? You have to handle systems with dizzying names like EPMS, BMS, DCIM, and DCOS. While we can't perfectly dissect these complex-looking systems from 1 to 100, I will use my 18 years of experience to explain the **'core functions' and 'basic structures'** they must have, in a way that is much more intuitive and easy to grasp than anyone else. ⚡️ On standby 24/7! Questions are always welcome. If there's a part that makes you tilt your head or a content that makes you think "What on earth does this mean?", don't suffer alone! Feel free to knock on my door anytime via the bulletin board or my email. Like an Uninterruptible Power Supply (UPS) that provides power without stopping for a single second, I'll always be waiting here to support you. 🔋 I hope my fierce survival story becomes a powerful weapon in your level-up journey. Now, shall we go crush this headache-inducing automatic control together in a fun way? Let's go! 💖

🛠️ [Course Introduction] "Real" HVAC Scheduling from an 18-Year Veteran Do you know what task takes up the most time and causes the most stress when working at a construction site? It is **'schedule revision.'** In the past, I also spent countless nights drafting HVAC construction and commissioning schedules. Construction sites are prone to delays due to unexpected variables, so wrestling with schedules every month—or even every week—was my daily routine. Looking back, the real reason I struggled so much was that **'no one ever properly taught me.'** There was no basic training on how HVAC relates to other trades or how to actually calculate the time required for construction or commissioning. Consequently, the schedules I spent so much time creating often lacked the accuracy needed to be useful on-site. Then, I had a great opportunity to receive intensive training on scheduling. Once I understood the principles, I honestly felt a bit frustrated. I realized that it’s quite simple once you know the core concepts, and I had wasted so much time during projects simply because I didn't know the method. Ultimately, a construction project is a battle of 'resource management.' The three most important resources to manage on-site are materials, manpower, and equipment. Schedules are created to manage these resources efficiently and are immediately revised when changes occur to prevent delays in the overall construction period. In other words, the schedule is a critical document that serves as the standard for overall project management. While large construction companies may have dedicated scheduling teams, practitioners in each trade must fundamentally be able to draft their own schedules. This is because the schedules of each part come together to form the massive framework of the entire project schedule. That is why I have prepared this course, packed with the practical insights I've gained from 18 years in the field. • Scheduling Basics: What types of schedules exist on-site, and what/how a practitioner should draft them. • HVAC-Specific Practice: Scheduling examples and exercises tailored to actual HVAC work, from representative duct installation to commissioning. • Know-how to Avoid Trial and Error: Tips to stop wasting precious time on meaningless schedule revisions like I did. If my explanation is insufficient or if you get stuck while studying, please do not hesitate to ask questions at any time. Just like an HVAC system that must run 24/7, I will be standing by to provide reliable answers to your questions!

"Have you ever seen months of overtime vanish with a single piece of paper?" Do you know what I felt most poignantly while managing five overseas EPC projects? It is the **'terror of understanding procedures.'** The interesting thing about the EPC world is that while every site is different, they are strangely similar, like a parallel theory. If you slip up in this game of procedural wits, you’re in big trouble. It is the fate of EPC that even a single task requires breaking through countless approval lines and gateways; if you fail to grasp this, the results of months of pouring your soul into your work can go down the drain overnight. 💡 'Real' experience built while being hammered by the Middle East's Big Three Fortunately, whether it was luck or grit, I managed to save and successfully complete every major overseas project I was assigned. Thanks to that, I am confident I can tell more vivid stories than anyone else on 'how to run an overseas EPC project well without failing.' In particular, you can't ignore the 18 years of experience I gained while being pushed to my limits by the three most notoriously difficult Middle Eastern clients (KOC, ADNOC, ARAMCO). I will extract and share only the most essential, life-saving insights on how these demanding clients pressure procedures and operate their systems. 🚀 For your 'life with evenings' To be honest, I created this lecture because I felt so bitter about the glorious 'trial and error' of my younger days. I truly hope my colleagues and junior engineers never have to experience the terrible mistakes I made—hitting rock bottom on-site day and night, falling into a mental breakdown because I knew nothing. I sincerely hope this survival guide becomes a cheat code that moves your clock-out time forward by even just one hour and reduces unfair overtime. 🛠️ 5-minute standby Q&A support If you find yourself thinking, "What on earth does this mean?" or if there is anything you don't understand while taking the course, please do not hesitate to reach out via the bulletin board or email. Like a strict safety manager who sticks to the site and never leaves, I am standing by, ready to give you clear answers to your questions! Let's find the strength, fighting!

Having spent 10 years as an HVAC engineer at overseas EPC sites, there is one truth I have realized most poignantly: "All hardships culminate in commissioning." In the case of HVAC, the construction team often handles everything up to commissioning, so everything from writing the procedures to the moment the valves are opened and the equipment is started was entirely my responsibility. As I wove together everything from massive equipment, ducts, and piping to precise automatic control cables and instruments, I often found myself confused as to whether I was an engineer or a maestro conducting a grand masterpiece of performance art. Furthermore, once you step into this rugged world of commissioning, even the reliable Quality team suddenly exits backstage. The pressure of having to shoulder everything from preparation to final inspection solely as the construction team... Thanks to that, I had to spend countless nights working overtime under the starlit skies of the Middle East. Whenever I stayed up all night amidst the hot desert winds, I thought desperately: "If someone had just spoon-fed me the big picture and the fine details of commissioning, wouldn't my clock-out time have been moved up just a little bit?" This lecture was born out of those numerous nights of overtime. It is my hope that the know-how I have accumulated through 14 years at construction sites and 3 years at data centers will be used to shorten the workdays of juniors and fellow engineers who are struggling in the field at this very moment. In this lecture, we will dissect the major equipment that serves as the heart of the plant HVAC system, the instruments that act like a fine neural network, and the mechanisms of automatic operation. I have also meticulously organized the objectives and essential equipment for each stage of commissioning, from Pre-commissioning to the Performance Test. Rather than a simple recitation of theory, I will vividly convey precautions that must never be missed on-site through real-life cases soaked in my blood, sweat, and tears. If there is anything in the explanation that feels slightly lacking or if you are confused about on-site application while listening to the lecture, please do not hesitate to ask questions. Like an emergency generator that reliably protects a site during a blackout, I am standing by, ready to run at full capacity to answer your questions at any time!

When I moved from the field of automatic control to a construction company, the thing that flustered me the most was the fact that 'no one teaches you how to read drawings.' Under the silent pressure of being expected to know everything as an experienced hire, I struggled to decode the alien language of drawings by constantly questioning the designers and learning the hard way. By the time I became proficient enough to handle tasks on my own, I met a colleague on a commissioning team at a Middle East site who had transferred from another company. Even that veteran colleague, who had seen it all, was struggling, saying, "I've never been taught how to read drawings, so I feel lost." That was when I realized for sure: 'Ah, not knowing how to read drawings is by no means an individual's fault.' Only when you accurately understand the drawings can efficient collaboration between engineers take place. So, I began explaining how to read drawings step-by-step to my colleagues and juniors, and that experience became the backbone of this lecture. To be honest, to those who know, a drawing is just a piece of paper with lines on it, but to those who don't, it is like an undecipherable cryptogram. If you cannot break through the drawings, the entire system remains a black box that is forever difficult to grasp. Since many engineers find automatic control difficult in itself, I felt there was a desperate need for a guide that could scratch that particular itch. After taking this course, you will be able to perfectly understand not only the types of automatic control drawings but also the detailed information contained within each one. You will gain practical insight, such as knowing exactly which drawing to pull out when you need specific information. I hope this lecture, which I have prepared while working in the field for 18 years, becomes a powerful weapon you can use immediately in your work. If there is anything you are curious about or find difficult to understand while taking the course, please don't struggle alone and feel free to ask questions at any time. Just like an Uninterruptible Power Supply (UPS) that stands by to provide power even during an outage, I will always be on full standby to answer your questions.

I thought I had seen it all after weathering the sandstorms of Middle Eastern construction sites and experiencing all sorts of hardships, but the moment I broke into the coldest sweat while working as a lead at an Equinix data center was when a "fire protection" issue erupted. Typically, operations teams revolve around two main pillars: electrical and mechanical. As a result, fire protection is always a blind spot. It is common for everyone to feel suffocated by fire safety issues whenever the Ministry of Science and ICT inspections or ISO certification seasons roll around. Since there are no internal experts, people end up relying on PMs or expensive consulting firms. This is where I gained a painful insight as an 18-year veteran engineer: "Those who build can never fully understand the perspective of those who operate." Even after spending a fortune on consulting, the advice often felt disconnected from the reality on the ground, and sometimes the answers were simply wrong. Out of sheer frustration, I decided to break through it myself. After obtaining licenses for both electrical and mechanical fire protection engineering, I sat down at the table with PMs and designers. Only then did I start to see the real picture. I realized that in this industry, there are very few people who truly understand data center fire protection within the context of "operations." Even now, having moved to a different company, the situation remains the same. In the end, there is no one who will prioritize or protect our operations team first. We only see as much as we know, and things only become as safe as the level of persistence we apply in our demands. That is why I created this course. Regardless of whether you hold a license or not, I have packed this course with "practical fire protection knowledge" that data center operations teams can use as an immediate weapon on-site, distilled from my 18 years of experience. If you get stuck while studying or encounter something in the field that doesn't make sense, don't struggle alone—feel free to ask anytime. Like an emergency engine pump that runs flawlessly even during a power outage, I will be standing by to answer you immediately.
