Adjusting the Airflow Direction for Multiple Indoor Units
Using a Single Remote Control Unit
• The airflow direction cannot be set using the remote control unit for the 1-way type (AS),
concealed duct type (D, U), and floor standing type (F, FM).
• If multiple indoor units are connected to a remote control unit, the airflow direction can be set for
each indoor unit by selecting the indoor units (see the operation below).
• To set the airflow for individual units, press the UNIT button. Display shows the indoor unit
number under group control. Set the airflow direction for the indoor unit that is shown on the
display.
• Each time UNIT is pressed, the indicator changes in the order shown below.
• When nothing is displayed, you can make the setting for all indoor units in one operation.
• The unit number is displayed as Outdoor Unit Number–Indoor Unit Number. It varies
depending on the number of units under group control.

Special Remarks

• Once the room temperature reaches the level that was set, the unit repeats the cycle of
turning on and off automatically.
• In order to prevent the humidity in the room from rising again, the indoor fan also turns off
when the unit stops operating.
• The fan speed is set to ''LO.'' automatically, and cannot be adjusted.
• ''DRY'' operation is not possible if the outdoor temperature is 15 °C or less.
• Because this appliance heats a room by utilizing 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 heat pump, use another heating appliance in
conjunction with this unit.
• When the outdoor temperature is low, frost or ice may form on the outdoor heat exchanger
coil, reducing the heating performance. When this happens, a microcomputer-controlled
defrosting system operates. At the same time, the fan on the indoor unit stops (or runs at
very low speed in some cases) and the ''STANDBY'' indicator appears on the display until
defrosting is completed. Heating operation then restarts after several minutes. (This interval
will vary slightly depending upon the outdoor temperature and the way in which frost forms.)
• For several minutes after the start of heating operation, the indoor fan will not start running
(or it will run at very low speed in some cases) until the indoor heat exchanger coil has
warmed up sufficiently. This is because a cold draft prevention system is operating. During
this period, the ''
• '' '' (standby) remains displayed during defrosting or when the compressor has been
turned off (or when the unit is running at very low speed) by the thermostat when the
system is in the heating mode.
• Upon completion of defrosting and when the compressor is turned on again, ''
(standby) will turn off automatically as heating operation resumes.
Should the power fail while the unit is running
If the power supply for this unit is temporarily cut off, the unit will automatically resume
operation (once the power is restored) using the same settings before the power was cut off.
