• Indoor function settings (page 10) / CURRENT TIME SETTING PROCEDURE (page 8)

ABOUT BATTERIES

• The recommendable effective period of a battery is about 6 to 12 months.(It depends on the usage.)
• The recommendable effective period is printed on the battery. This may be shorter due to manufacturing time of the unit. However the battery may be still working in order after expiry date.
• The batteries packaged with the remote control are supplied in order to check operating conditions when usage begins, and subsequently, the life of these batteries may be shorter than that of new batteries.

ATTENTION

• When replacing batteries, replace with two new AAA batteries at the same time. (Alkaline batteries are recommended.)
• Do not mix old and new batteries or types of batteries (for example, manganese and alkaline batteries).
• Do not use rechargeable batteries.

CAUTIONS ON SWITCH OPERATIONS

• When operating the “FUNCTION SETTING”, “TIME SET UP”, or “ACL” switches, press it straight downward using an object with a short pointed end such as a ballpoint pen. Do not press those switches forcefully at an angle using an object with a long and sharp end such as a mechanical pencil. Otherwise, the buttons may not pop up to their original positions.

HOW TO OPERATE

• If you press each button on the wireless remote control while pointing it at the signal receiver of the air conditioner body, a signal is sent. When the signal has been received without a problem, the RUN indicator LED blinks.

ATTENTION

• The buttons on the remote control must be operated carefully and securely. If an error occurs on the display of the remote control
• Press the ACL switch with a ballpoint etc. Press the ACL switch to reset to the time set up mode. Set the time correctly.

ABOUT REMOTE CONTROL HOLDER

• The remote control can be mounted on the wall or pillar with the remote control holder. Slide from the upper part of the holder to place or take out the remote control.

ATTENTION

• If the remote control signal receiver is exposed to direct sunlight or strong light, the receiver may not be able to receive a signal. In this case, block the sunlight or dim the light.
• Do not block the signal between the remote control and the remote control signal receiver.
• Do not point the air conditioner wireless remote control at devices such as a TV set that have their own wireless remote control.
• The remote control must be handled carefully.
• Remove the batteries when the remote control is not used for a long time.
• Even if the remote control is not found or damaged, you can operate the air conditioner with itself. See “10. BACKUP SWITCH OPERATION” on page 10.

HOW TO OPERATE

ATTENTION

• Turn on the power supply of both indoor/outdoor units for six hours before starting the unit to protect the units. (The crankcase is conducted and the compressor is heated) Do not turn off the power supply. (The crankcase heater is conducted while the compressor is stopped, preventing failure of the compressor due to accumulation of liquid refrigerant by keeping the compressor warm.)
• The operation of remote control must be performed slowly and steadily.

Guideline of room temperature setting

• COOL ….. 26 to 28°C
• DRY …….. 21 to 24°C
• HEAT …… 22 to 24°C
• FAN……… TEMP setting is unnecessary
  • Operation mode can be changed even when the unit stops.
  • If you operate under the same condition (operation mode, set temperature, air flow, louver) just follow step 1, no other operations are necessary. The conditions which were set previously are indicated on the remote control.

OPERATION

1. Press ON/OFF button. The operation display light (Green) turns on, and the operation starts.
2. Press MODE button. The mode will change in the following order by pressing the button.

NOTICE

• The louver movement does not match the display when the louver is swinging. This is not an error.
• The louver is set to horizontal swing mode to prevent you from being exposed directly to cold air during heat preparation or heat defrosting. (The set position shown on the display of the remote control does not change.)
• If you select the swing mode while the anti draft setting is enabled, the airflow is set to the horizontal direction.

ATTENTION
Do not set the swing louver downward for a long period of time when the cool mode is active. Otherwise, any dew that has formed on the side panel may drop. (In case of FDE)

Press the L/R button. (RCN-EK2 only)
The left/right airflow changes as shown below each time the button is pressed .

NOTICE

• The louver movement does not match the display when the louver is swinging. This is not an error.
• When there is a wall on the left of the air conditioner, we recommend that the airflow be directed to the right, and when there is a wall on the right of the air conditioner, direct the airflow to the left.

Press the 3D AUTO button. (RCN-EK2 only)
Switch whether or not to enable or disable 3D AUTO mode. 3D AUTO mode automatically controls the fan speed or airflow direction, which helps efficiently air condition the entire room.

NOTICE

• You cannot switch the up/down airflow or left/right airflow in 3D AUTO mode. When changing, cancel 3D AUTO mode.
• If 3D AUTO is selected while an FDK model with the switchable left/right airflow function is connected to an indoor unit without the switchable left/right airflow function, the airflow direction of the model that does not have this function is set to the direction that was selected before 3D AUTO mode was enabled.
• The left/right airflow switching or 3D AUTO cannot be operated from SC-SL2, SC-SL3, or SC-SL4. Even if the airflow direction is changed from SC-SL2, SC-SL3, or SC-SL4 during 3D AUTO mode, 3D AUTO is not canceled.

Press the ECO button
Start or cancel the energy-saving operation. (In the cool, heat, or auto mode only) The energy-saving mode automatically controls the performance depending on the outdoor temperature, setting the standard temperature to 28°C in the cool mode and 22°C in the heat mode. This enables the energy-saving operation without compromising room comfort.

Press the HI POWER button
Start or cancel the high power operation. (In the cool or heat mode only) The high power operation quickly sets the room temperature to a comfortable level. This mode accelerates the operation performance for 15 minutes, and automatically returns to the normal mode after that.

NOTICE
• When the system is connected to a centralized device, using the centralized
device to specify the set temperature or fan speed during high power
operation will cancel high power operation. In that case, the set temperature
or fan speed specified using the centralized device may not be applied.
• High power operation cannot be used if 4-speed is “disabled”
using the indoor unit or remote control.
