What this means

During multi-system operation, a blinking operation indicator lamp can indicate standby mode when the selected operation conflicts with another indoor unit. This is a normal status, not an error.

What you can check yourself

  • Wait for the other indoor unit to finish or select compatible operation modes on the connected indoor units.
