SBA 567: Tuning a PID Loop

Is your PID loop constantly hunting, responding too slowly, or struggling to maintain a stable setpoint?

For building automation professionals, PID tuning can be one of the most challenging parts of optimizing HVAC control systems. What looks like a simple tuning issue could actually involve mechanical problems, changing loads, or multiple control loops working against each other.

In Episode 567 of the Smart Buildings Academy Podcast, discover what it takes to move beyond trial-and-error adjustments and approach PID tuning with a repeatable, systematic process.

Whether you're commissioning a new system, troubleshooting an unstable loop, or improving an existing control sequence, understanding how your system responds is essential to achieving reliable performance.

Topics Covered

• Identifying the factors that influence PID loop stability and response

• Understanding bump tests and what they reveal about system behavior

• Exploring tuning methods for different HVAC control applications

• Recognizing challenges with interacting loops, reset strategies, and seasonal changes

• Evaluating tuning performance and documenting results for long-term reliability

Stop relying on default settings and guesswork. Learn what separates a loop that simply works from one that delivers consistent, reliable control.
