What happens here

The indoor unit is now fully installed and operational, blowing cool air at 62 degrees Fahrenheit. The creator identifies a wiring mistake he made: the pre-wired inputs for the indoor unit were incorrect (hot, neutral, hot instead of line 1, line 2, and neutral). He corrected the wiring to match the installation manual, ensuring proper function. He reiterates that he will cover the lines with channel covers later for a cleaner aesthetic and that all units are now controllable via a smartphone app.

Goal: Complete indoor unit installation, correct wiring issues, and confirm functionality.
