HVAC DDC Basics

Covering the basics of Heating, Ventilating and Air Conditioning (HVAC) Direct Digital Controls (DDC), this course enables students to understand the fundamentals of HVAC DDC systems design.  The course emphasizes critical “Do’s and Don’ts” and accepted rule-of-thumb checks in the design of HVAC controls.

Broken into the following four major categories, this course provides a sound foundation for understanding DDC system design:  1) The Six Steps of HVAC DDC System Design; 2) DDC Controller; 3) Basics of HVAC Controls; and 4) Building Automation, LEED, and Commissioning.

Course Highlights:

  • The Six Steps of HVAC DDC System Design
  • HVAC DDC Components such as Flow Meters, Temperature, Humidity, and Pressure Sensors
  • DDC Controllers, Smart Sensors, and Actuators
  • Application Specific Controllers
  • The Most Commonly used HVAC Control Systems
  • DDC Signals
  • System Schematics
  • Control Point Designations
  • Point List
  • DDC System Architecture

  Course Benefits:

  • Distinguish between a Digital Output, Digital Input, Analog Input, and Analog Output.
  • Learn the systematic process of designing HVAC DDC systems.
  • Discern between Supervisory Control and Data Acquisition (SCADA) and Programmable Logic Controller (PLC) systems.
  • Discover the three most commonly used wireless technologies for building automation systems.
  • Identify the basic characteristics of the five types of the most commonly used HVAC control systems.
  • Examine the advantages of Proportional Plus Integral and Proportional Plus Integral Plus Derivative control actions.
  • Review methods to use the building automation system as a tool for commissioning as well as LEED measurement and verification.
