connected outdoor unit models will not appear
on the display.
What the blinking mode icon means
The mode icon will blink when other indoor units in the same refrigerant
system (connected to the same outdoor unit) are already operated in a
different mode. In this case, the rest of the unit in the same group can
only be operated in the same mode.
