Icons for all indoor units are blue.
It originally showed up as U9-01 error and all yellow, but changed.
I have recently changed a sub pcb in the master outdoor unit. A phase monitor was wired wrong (in series with x2a on sub instead of x2a on main). I fixed all wiring in those circuits. Three days later this error appears. With the U9-01 I know where to start. With the blue icons and no error, where do I even begin?
