How to Design HVAC Controls Logic Step by Step Paperback – November 24, 2025

The complexity of modern buildings demands more than just well-designed mechanical systems; it requires intelligent control. HVAC controls are the brain of any building, ensuring that occupants are comfortable, processes run reliably, and energy is used efficiently. However, the step from an HVAC system concept to a functional, reliable, and optimized control logic sequence often remains a significant hurdle.This book is designed to bridge that gap. It is a practical, step-by-step guide that demystifies the process of creating robust Direct Digital Control (DDC) logic. We move beyond theoretical principles to focus on the practical application: how to define operational objectives, translate them into a clear Sequence of Operation (SOO), and develop the precise control code that makes a system perform exactly as intended. Whether you are a mechanical engineer, a controls specialist, or an experienced technician, this guide provides the foundational methods and advanced strategies necessary to master the art and science of HVAC controls design.
