Confirm the listed meaning of Samsung CAC cassette / ducted E606, note the unit that shows the code and its model, and match the service manual before diagnosis.
What does Samsung E606 mean?
Samsung CAC cassette / ducted E606 is listed as wired-controller COM1 and COM2 connections are crossed in the Samsung CAC Inverter 50 Hz Australia fault list.

A cause should be recorded only after the matching service-manual checks are completed.
