A. In Heating Mode: ( )
(1) When the room temperature drops below 46°F, Heating
Operation will begin.
(2) When the room temperature rises to above 53°F, Heating
Operation will stop.
The above actions will repeat so that the room temperature is
maintained at about 50°F.

• Unoccupied Mode triggers Heating or Cooling Operation in
response to the room temperature, but when this happens, the
remote controller will continue to display the Operation mode set by
the user.
• If the room temperature rapidly changes, the room temperature
may get over the upper or lower limit when the unoccupied function
is activated.
NOTE
• The remote controller should be used in the location specified in
"REMOTE CONTROLLER INSTALLATION POSITION" on page 8.
• The air conditioner's stop order (stated in (2) / above) is valid only
when the unoccupied function is operated.

SPECIAL REMARKS

''DRY'' ( ) Operation
How it works?
• Once the room temperature reaches the level that was set, the
unit's operation frequency is changed automatically.
• During DRY operation, the fan speed automatically runs at lower
speed for providing a comfortable breeze.
• ''DRY'' operation is not possible if the indoor temperature is 59 °F
or less.
Heating ( ) Operation
Heating performance
• When High power operation
, HIGH
or MEDIUM
LOW
, Quiet operation
speed may not be reduced to the desired setting immediately but
rather it may be reduced slowly in steps due to the operating status
of the air conditioner. (A maximum of 5 minutes are required for the
change to be completed.)
• Because this air conditioner heats a room by drawing in the heat of
the outside air (heat pump system), the heating efficiency will fall
off when the outdoor temperature is very low. If sufficient heat
cannot be obtained with this air conditioner, use another heating
appliance together with it.
Defrosting
• When the outdoor temperature is low, frost or ice may form on the
heat exchanger coil, reducing heating performance. When this
happens, a microcomputer defrosting system operates. At the
same time, the fan on the indoor unit stops and the OPERATION
lamp lights red and orange alternately until defrosting is completed.
Heating operation restarts after several minutes. (This interval will
vary slightly depending upon the outdoor temperature and the way
in which frost forms.)
Cold draft prevention
• For several minutes after the start of heating operation, the indoor
fan runs at a lower speed until the indoor heat exchanger coil has
warmed up sufficiently. However, the fan may remain stopped when
the room temperature is low. This is because the COLD DRAFT
PREVENTION SYSTEM is in operation.
Cooling ( ) operation
• Sometimes the indoor unit may not get to the set fan speed such as
LOW under cool operation at very low outdoor temperatures due to
the indoor unit being protected from ice or frost.
Power failure during operation
• In the event of power failure, the unit will stop. When the power is
resumed, the unit will restart automatically in approximately
5 minutes by the remote controller.
If the remote controller is on and left in a location where the unit
can receive a signal, then the unit will automatically restart in
approximately 5 minutes of power being restored.
Clicking Sound
Clicking sound is heard from the air conditioner
• In heating or cooling operation, any plastic parts may expand or
shrink due to a sudden temperature change. In this event, a
clicking sound may occur. This is normal, and the sound will soon
disappear.
Remote Controller
• The remote controller sends the setting condition to the air
conditioner regularly at five minute intervals.
