PID Control Explained | How PID Controllers Work in HVAC & Building Automation Systems (BAS)

Ever wondered how HVAC systems maintain a steady temperature without constantly turning on and off? The answer is PID control. In this video, you’ll learn what a PID (Proportional-Integral-Derivative) controller is, how it works, and why it’s the backbone of modern HVAC, Building Automation Systems (BAS), and industrial control systems. We’ll cover: What PID means Proportional, Integral, and Derivative explained Setpoint, Process Variable (PV), and Error Why PI control is commonly used in HVAC Real-world BAS examples Common PID tuning mistakes Practical applications with AHUs, VAV boxes, VFDs, valves, and pumps Whether you’re an HVAC technician, BAS programmer, controls engineer, or a student learning automation, this video will help you understand one of the most important concepts in control systems. 👍 If you found this video helpful, don’t forget to Like, Subscribe, and Turn on Notifications for more HVAC and BAS training content every week. #HVAC #BuildingAutomation #BAS #PID #ControlsEngineering #Automation #DDC #HVACTechnician #PLC #ControlSystems #VFD #Engineering #SmartBuildings #IndustrialAutomation
