About Heating Operation
Air is blown out when operation is stopped: The indoor unit fan sometimes
rotates for approximately 1 minute after operation stops in order to
dissipate residual heat inside the indoor unit.
Fan Operation
The fan operation circulates the air within the room. The effectiveness of
ventilation can be improved by performing this operation together with the
operation of the ventilator.

In this case, the send data was disturbed by the noise, etc. Check the
transmission line.

Meaning of the Defrosting Indication
Frost forms in an outdoor unit when the outside air temperature is low and
the humidity is high. This indication appears while the operation to melt this
frost is being performed.
The defrosting operation ends after approximately 7 minutes (maximum 12
minutes).
During the defrosting operation, the fan is stopped because the heat
exchanger of the indoor unit becomes cold.
* With models that have multiple outdoor units connected, the fan
continues operating when the heating operation and defrosting operation
are performed in combination.
* The fan may sometimes operate during defrosting depending on the
settings. For details on the settings, consult the dealer.
Ventilation Link Operation
This is a function that starts ventilator operation automatically when the air
conditioner starts operating, and improves the effectiveness of ventilation
by mixing indoor air and fresh outdoor air.
