Take the whole system apart.
Drag to spin. Pull the explode slider and the cabinets open up around the compressor, the reversing valve, the blower wheel. Tap any numbered pin to fly the camera there and read what that part does in the field.

Three ways this earns its keep
Before you open a panel
Explode the unit on your phone in the van and know exactly where the board, the reactor and the valve are sitting before the screws come out.
Explaining it to a customer
Turn the screen around. Showing a homeowner what a reversing valve is takes thirty seconds instead of five minutes of hand-waving.
Training an apprentice
Hand them the explorer and the Level 1 component tour together. They'll walk onto their first ductless call knowing what they're looking at.
The explorer is the appetiser.
The course is nine hours of the same parts being cleaned, diagnosed, replaced and commissioned on real jobs.
