TEST OPERATION
This operation state is to be used only when the remote controller is
defective or lost.
Turn on the test operation switch only when the room temperature is
less than 16°C.
When the emergency operation switch is turned on,
you hear a sound indicating the beginning of
this operation.
Continue to press and hold the test operation switch for more than
5 seconds. After you hear the “Bl” sound twice, release your nger
from the switch; the test operation starts and the air conditioner
starts with the air ow speed setting at “HI”.
If you use the remote control device to stop the test run, the conditioner will then run based on the working mode
displayed on the remote controller.

To cancel:

resume function is canceled.
