Control Sequence Fundamentals

Course Description

This course provides a comprehensive study of HVAC control sequences. While this course will address theory, it is theory tempered by over a decades worth of experience working on some of the most complex BAS projects in the world. Students will learn the why behind BAS control strategies and will leave with a solid understanding of “how” systems work.

Length (hours)

20

Audience

This course is targeted towards salespersons, technicians, designers, operators, consulting engineers, and project managers who have at least 6 months of experience with BAS systems or have been through our BAS fundamentals course.

Pre-Requisite Knowledge

Fundamental awareness of the parts and pieces of BAS. 

Objectives

• Master how HVAC systems function and how to control them
• Demonstrate knowledge of BAS controls theory in HVAC systems
• Develop the ability to make design and programming decisions based on system requirements

Key Topics

• Learn what control sequences are and how control sequences are structured.
• Master the step-by-step process of interpreting control sequences.
• Create the foundational system knowledge that allows the student to understand the relationship between space control and upstream systems.
• Discover the different ways of controlling and conditioning the air stream along with the interrelationships between air systems and water systems.
• Learn what hot water systems are, how they are controlled, and how other systems interact with and influence hot water systems.
• Gain an awareness of how and why chilled water systems are used, the methods and processes that control chilled water systems, and the limitations of chilled water systems.
• Learn what the different strategies for pumping and piping are and how these strategies effect the control and efficiency of water based heating and cooling.
• Learn how unitary systems are controlled and how the effect existing building systems.
• Learn what a 2-pipe system is and how to properly control building systems that are supplied by 2-pipe systems.
• Learn what CRAC and CRAH systems are, how underfloor cooling works, and the gotchas associated with controlling integrated systems.
• Learn what VRV and VRF systems are, how they are controlled, and the complexities of integrating and controlling non-standard systems.
• Learn the three different kinds of recovery systems, how they are controlled, and the effect they have on other systems.
• Discover the multiple forms of integration, how the integration process works and how to interpret integration specifications.
