Details of operation
According to the room temperature when the operation starts, the opera-
tion mode is automatically set to COOL, DRY or HEAT. However, when
operation is started again within 2 hours after it is stopped, the same
operation mode before the operation is stopped is selected. The opera-
tion mode selected first is not changed even if the room temperature
changes. If the operation mode does not match the room condition, se-
lect the appropriate operation mode by pressing the
MODE
button.

Description of “AUTO RESTART FUNCTION”
■
These units are equipped with an auto restart function. When the main power is turned on, the air conditioner will start
operation automatically in the same mode as the one set with the remote controller before the shutoff of the main power.
■
If the unit was set to off with the remote controller before the shutoff of the main power, it will remain stopped even after
the main power is turned on.
■
If the unit was in the emergency operation before the shutoff of the main power, it will start operation, when main power
comes on, in the same mode as the one set with the remote controller before the emergency operation.
■
If the unit is operated in “I FEEL ...” mode before power failure, the operation is not stored in the memory. In “I FEEL ...”
mode, the operation is decided by the initial room temperature at (re)start.
■
Since the air conditioner has been shipped from the factory with the COOL mode saved in the memory for auto restart
function, it starts cooling operation when the user turns on the main power for the first time after installation.
