Course Overview
This course provides a comprehensive, manufacturer-independent understanding of DDC systems, covering everything from control loops and sensor calibration to system architecture and cybersecurity. Participants will explore open protocols like BACnet, learn how to avoid common pitfalls in HVAC control, and gain practical skills in programming, system integration, and commissioning. With a strong focus on real-world applications, this course empowers engineers and facility professionals to make informed decisions and implement robust, future-ready control systems.
Learning Outcomes
Master direct digital control systems by learning how to:
- Define system requirements and select appropriate hardware, software, and protocols—including BACnet—for HVAC and building automation.
- Plan and implement robust DDC architectures with attention to IT integration, cybersecurity, and interoperability.
- Troubleshoot and optimize control strategies for air handling units, VAV systems, central plants, and other HVAC applications.
Examine the capabilities of DDC systems and learn:
- The importance of having a planned system architecture.
- If open protocols add value with respect to your requirements.
- Control strategies for a variety of HVAC system types.
Who Should Attend?
- Consulting and design engineers working on HVAC and building automation systems.
- Facility managers, building owners, and commissioning authorities seeking to optimize system performance.
- Technicians and contractors responsible for installing, programming, or maintaining DDC systems in commercial or institutional facilities.
Additional Information
This course will give you a broad range of knowledge to understand the principles and technical concepts used by various manufacturers. This understanding is essential to acquire, implement, and operate a cost-effective system. While various manufacturers are discussed during the course, the course content is not specific to any vendor.
A laptop computer or tablet is required for the course.
