Variable Speed Cert

Link training class provides technicians and installers with hands-on education on setting up, wiring, and diagnosing American Standard’s digital communicating HVAC system architecture.

Course Overview & Objectives

System Architecture: Learn how the 4-wire (or optional 2-wire) digital communication bus replaces standard 24V wiring to connect the thermostat, air handler, and heat pump.

Component Auto-Addressing: Understand how system components auto-identify, broadcast serial numbers, and stream live runtime data.

Advanced Diagnostics: Learn to read real-time system performance data, transducer metrics (superheat/subcooling), and fault codes directly through the control interface rather than traditional analog manifold gauges.
