5.2. Fan control for energy saving
In the Cooling or Dry operation, when the room temperature reaches the
set temperature, the indoor unit fan rotates intermittently to save power.
This function is deactivated at the time of purchase.
To change the setting, refer to the operation manual of the remote
controller.
Even if the setting is changed, if the fan speed is set to Auto in Cooling
or Dry mode, this function still works to suppress the di󰀨usion of
circulated indoor humidity.
6. OTHER OPERATIONS
6.1. Minimum heat operation
NOTE:
• This function is available only by wireless remote controller.
Minimum heat operation maintains the room temperature at 50 °F
(10 °C) so as to prevent the room temperature to drop too low.
NOTES:
• When the room temperature is warm enough, This operation will not
be performed.
• In case of multi-split type air conditioner, if other indoor unit is
used for heating, the temperature of the room where the Minimum
heat operation is applied will rise. When using the Minimum heat
operation, we recommend all indoor units should be run under the
Minimum heat operation.

8. GENERAL INFORMATION
■
Inverter
On start-up, the air conditioner will operate at maximum capacity to
bring the room quickly down to desired temperature.
Once the room temperature reaches to the set temperature, the air
conditioner will reduce its capacity and energy usage to the minimum
capacity and input ratings.
■
Heating performance
This air conditioner operates on the heat-pump principle, absorbing
heat from air outdoors and transferring that heat to the indoor unit. As a
result, the operating performance is reduced as outdoor air temperature
drops.
If you feel that the heating performance is insu󰀩cient, we recommend
you to use this air conditioner in conjunction with other kinds of heating
appliance.
Consult with your installation technician to ensure the unit is correctly
sized for the room space required.
Heat-pump air conditioners heat your entire room by recirculating air
throughout the room, with the result that some time may be required
after rst starting the air conditioner until the room is heated.
■
Automatic defrosting operation
When outdoor temperature is very low with high humidity, frost may
form on the outdoor unit during the Heating operation, and it could
reduce the operating performance of the product.
For frost protection, an Automatic defrosting function is equipped in this
air conditioner.
If frost forms, the air conditioner will temporarily stop, and defrost circuit
will operate briey (maximum of 15 minutes.)
If frost forms on the outdoor unit after the Heating operation, the outdoor
unit will stop automatically after it operates for a few minutes. Then the
automatic defrosting operation starts.
If you set to the Heating operation during the Automatic defrosting
operation, the Automatic defrosting operation will continue. The Heating
operation will begin after completion of defrosting. As a result, it may
take some time before warm air is emitted.
■
Hot start
The indoor unit prevents cold drafts when the Heating operation be-
gins.
The indoor unit fan will not operate or it will operate at a very low speed
until the heat exchanger reaches the set temperature.
■
Auto-restart function
In event of power interruption such as a blackout, the air conditioner
stops once. But it restarts automatically and performs previous operation
when the power supply is resumed.
