This course provides a foundational overview of Heating, Ventilation, and Air Conditioning (HVAC) control systems used in residential, commercial, and light industrial buildings. Students will explore the basic principles of temperature, humidity, and airflow control, along with the components that make modern HVAC systems operate efficiently and reliably. Topics include thermostats, sensors, actuators, relays, control valves, dampers, and an introduction to building automation systems (BAS). Learners will gain a clear understanding of control sequences, wiring basics, and common troubleshooting techniques. The course also introduces digital controls and direct digital control (DDC) concepts used in today’s energy-efficient buildings. By the end of the course, participants will be able to read basic control diagrams, understand system operation sequences, and identify key components within an HVAC control system. This course is ideal for entry-level technicians, maintenance personnel, facilities staff, and anyone seeking a strong foundation in HVAC controls
