QTM 220 Quantum HD Unity Compressor Controller I

QTM 220 introduces operators and technicians to the Quantum HD Unity compressor controller, focusing on how refrigeration compressors are monitored, controlled, and protected in industrial refrigeration systems.

This course is intended for refrigeration operators, maintenance personnel, and technicians who interact with Quantum‑controlled compressors and need to understand what the controller is doing, what information is being presented, and how to safely interpret system behavior.

The course begins with an overview of the Home Screen and navigation, establishing how operators access system status, alarms, trends, and menus. Core control concepts are introduced next, including digital and analog control, forward‑acting control loops, and proportional‑integral (PI) behavior as applied to compressor capacity control.

QTM 220 places significant emphasis on sensor inputs and calibration, explaining how pressure transducers, temperature sensors, motor current feedback, and mechanical calibrations affect controller accuracy and compressor safety. Learners also study capacity control strategies, configuration impacts, and critical discharge, suction, and oil safeties.

The course concludes by introducing online resources, including FrickControls.com, the JCI Knowledge Exchange, and manufacturer training videos that support safe, informed operation.

QTM 220 serves as the foundational Quantum controller course, preparing learners for advanced troubleshooting, configuration, and commissioning training.
