E – 3063 HVAC Controls I: Sensors and Signals
$25.00
Courses Included
Modern HVAC systems have evolved into highly integrated, sensor-driven control systems designed to deliver comfort, energy efficiency, indoor air quality, and operational safety. Unlike traditional HVAC equipment that relied on simple thermostats and manual controls, today’s systems depend on a wide range of sensors, signal types, wiring configurations, and control logic to monitor physical conditions and respond intelligently to changing building demands.
Sections 1 through 13 introduce the foundational components of modern HVAC sensing and control. These sections cover how physical conditions such as temperature, humidity, pressure, airflow, air quality, and occupancy are detected; how sensor signals are transmitted using analog, binary, and multi-state methods; how controllers interpret these signals; and how wiring configurations and contact logic affect system reliability and safety.
A strong understanding of these topics is essential for HVAC technicians, controls specialists, and engineers. Mastery of sensor types, signal standards, and wiring practices enables accurate installation, effective troubleshooting, proper commissioning, and long-term system performance. These sections form the technical foundation required for more advanced topics such as sequencing, PID control, building automation systems, and diagnostics.
