• Operation modes that are not available
to the 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.
Automatic operation
According to a set temperature, cooling operation starts if the room
temperature is too hot and heating operation starts if the room
temperature is too cold.
During automatic operation, if the room temperature changes and
remains 2.0 °C, 4 °F or more above the set temperature for 15
minutes, the air conditioner switches to cool mode. In the same way,
if the room temperature remains 2.0 °C, 4 °F or more below the set
temperature for 15 minutes, the air conditioner switches to heat mode.
Cool mode
15 minutes (switches
from heating to cooling)
15 minutes (switches
from cooling to heating)
Because the room temperature is automatically adjusted in order to
maintain a fixed effective temperature, cooling operation is performed
a few degrees warmer and heating operation is performed a few
degrees cooler than the set room temperature once the temperature is
reached (automatic energy-saving operation).
