Like a chain, the BAS is only as good as its most poorly performing component. Identifying and replacing the poorly performing input and output devices restores the BAS and the controlled equipment to optimum efficiency and reliability while improving occupant comfort. Therefore, more emphasis needs to be placed on education and training of the staff and this book is a small step in that direction. The people performing the building automation system work have a myriad of different education, knowledge, training, and experience levels. Consequently, the means and methods used to test and calibrate them are equally varied. This book is an attempt to move toward industry-wide acceptance, adoption, and implementation of standard testing protocols for each BAS input and output device. It is a lofty goal, but it is well worth the effort.
Francisco Valentine, PE is a graduate of West Virginia University's School of Mechanical Engineering. He started his career in Heating, Ventilating, and Air-Conditioning (HVAC) as a mechanical and plumbing design engineer. Through the years, he expanded his skill set to include energy project development, commissioning, TAB (Testing, Adjusting, and Balancing), and Direct Digital Controls. This varied range of knowledge and experience provides a unique perspective upon which the featured book is based. We are sure that you will benefit from the experience, knowledge, and lessons learned from this accomplished field engineer.

Provide a resource for independent, self-paced training and education for those that specify, design, install, test, calibrate, service, and troubleshoot Building Automation Systems. In addition, this book should help to standardize the testing and calibrating methods used on BAS input and output devices.

Chapters 1 through 7 provide foundational information and preliminary data which are applicable to the chapters that follow.
Chapters 8 through 18 are focused on Binary Input devices.
Chapters 19 through 31 are focused on Analog Input devices.
Chapters 32 through 36 are focused on Binary Output devices.
Chapters 37 through 41 are focused on Analog Output devices.
Chapters 42 provides the testing protocol for VFDs which require multiple points (binary inputs, analog inputs, binary outputs, and analog outputs) and a good understanding of their operation is required to properly test and troubleshoot them. Chapter 43 provides the answers to the Review questions at the end of most chapters. Chapter 44 provides a summary of abbreviations used throughout the book.
