Best Practices for Installing DDC Control Systems

Share This

Course Length: 3 hours

A facility’s direct digital controls (DDCs) form a living, breathing system that an owner will use throughout the life of the building. Many control systems do not work as designed on Day One, much less in two to three years. Adding to the complexity are subcontractors, who often do not routinely install control systems, as well as installing contractors, who have broad discretion to determine aspects of how controls are instituted. Many manufacturers (especially in developing countries) sell DDC controls and components with little information on installation practices or quality control guidelines.

If quality installations are promoted and better standardized, the short- and long-term success of the controls system will be greatly improved. This course will bring tools to ensure uniformity to consultants, contractors, and code officials, while specifically benefitting consulting engineers, DDC design integration engineers, commissioning authorities, and contractors who install DDC. Upon completion of this course, registrants will better understand how to properly install a control system and what to look out for in the process. Attendees will also learn to commission these systems properly for the benefit of the owner and the life of the building.

This course covers best installation practices of DDC systems. The discussion will include terminology, wiring sizes and types, panel building, grounding, testing, and commissioning of the DDC system to produce specified comfort levels. Upon completion attendee, will be able to understand drawings, schematics, specifications, and test procedures to determine proper DDC system operation.
