Component Library

In short

Add each component to the canvas, explore its terminals, and test how it works. Build mini-circuits to see every component in action. You will add and examine each heating component, connect zone valves and test operation, explore 3-port valve positions, wire programmers and thermostats, use multimeter to test component states.

Comes after Electrical Fundamentals.
