VARIOUS FUNCTIONS
■
Auto Restart Control
AUTOMATIC OPERATION
The device will automatically determine the mode of operation, HEAT, COOL, or DEHUMIDIFY, depending
on the initial room temperature. The selected mode of operation will change when the room temperature
varies. However, the mode of operation will not change when indoor unit connected to multi type outdoor
unit.
Press the (FAN SPEED) button. AUTO, LOW and SILENT are available.
Press the (START/STOP) button.
Operation starts with a beep.
Press the button again to stop operation.
■
As the settings are stored in memory in the remote controller, you only have
to press the
(START/STOP) button next time.
You can raise or lower the temperature setting as necessary by maximum
of 3°C.
Press the temperature button and the temperature
setting will change by 1°C each time.
• The preset temperature and the actual room temperature may vary
somewhat depending on conditions.

START
STOP
Press the FUNCTION selector so that the display indicates the
(AUTO) mode of operation.
• When AUTO has been selected, the device will automatically
determine the mode of operation, HEAT or COOL depending on
the current room temperature.
• When AUTO is first selected, the device will determine the current
room temperature and select the proper operation mode
accordingly.
• When the air conditioner has adjusted the room's temperature to
the near preset temperature, it will begin to monitor operation. If
the room temperature subsequently changes, the air conditioner
will once again select the appropriate operation (heating or cooling)
to adjust the temperature to the preset temperature. The monitoring
operation range is + 3°C relative to the preset temperature.
• If the mode automatically selected by the unit is not satisfactory,
manually change the mode setting (heat, dehumidify, cool or fan).
• If there is a power failure, operation will be automatically restarted when the power is resumed with
previous operation mode and airflow direction.
(As the operation is not stopped by remote controller.)
• If you intend not to continue the operation when the power is resumed, switch off the power supply.
When you switch on the circuit breaker, the operation will be automatically restarted with previous
operation mode and airflow direction.
Note: 1. If you do not require Auto Restart Control, please consult your sales agent.
2. Auto Restart Control is not available when Timer or Sleep Timer mode is set.

NAMES AND FUNCTIONS OF EACH PART
REMOTE CONTROLLER
• This controls the operation of the indoor unit. The range of control is about 7 meters. If indoor lighting is controlled
electronically, the range of control may be shorter, in some cases, the control signal may not be received.
This unit can be fixed on a wall using the fixture provided. Before fixing it, make sure the indoor unit can be
controlled from the remote controller.
• Handle the remote controller with care. Dropping it or getting it wet may compromise its signal transmission
capability.
• After new batteries are inserted into the remote controller, the unit will initially require approximately 10 seconds
to respond to commands and operate.
Precautions for Use
• Do not put the remote controller in the following places.
• In direct sunlight.
• In the vicinity of a heater.
• Handle the remote controller carefully. Do not drop it on the floor, and protect
it from water.
• Once the outdoor unit stops, it will not restart for about 3 minutes (unless you
turn the power switch off and on or unplug the power cord and plug it in again).
This is to protect the device and does not indicate a failure.
• If you press the FUNCTION selector button during operation, the device may
stop for about 3 minutes for protection.
