FEATURES
Energy saving
z
High energy saving was realized by making the indoor unit and outdoor unit fan motor and compressor all DC and optimal design of the refrigerant cycle.
Quiet operation
z
Air ow mode can be set in 4 steps and more detailed air ow setting is possible.
45 type: 34 dB at operation in the Quiet mode.
Filter sign
z
Dirtying of lter is detected by air conditioner operating time and the user is informed.
Economy operation
z
The power consumption can be reduced.
Wired/wireless simultaneous use possible
z
Wired remote controller and wireless remote controller can be simultaneously used.
Flexible installation
z
A high installation of the construction of the ceiling and degree of freedom corresponding to height is possible.
Double auto swing
z
Combination of up/down and right/left air direction swing allows three-dimensional air direction control.
Since up/down air direction aps operate automatically, according to the operating mode of the unit, it is possible to set the air direction based on the operating mode.

INDOOR UNIT (Setting by remote controller)12-2.
The function settings of the control of the indoor unit can be changed by this procedure according • to the installation conditions. Incorrect settings can cause the indoor unit malfunction.
After the power is turned on, perform the “FUNCTION SETTING” according to the installation • conditions using the remote controller.
The settings may be selected between the following two: Function Number or Setting Value. • Settings will not be changed if invalid numbers or setting values are selected. •
PREPARATION
Turn on the power. •
* By turning on the power indoor units, so make sure the piping air-tight test and vacuuming have
been conducted before turning on the power.
* Also check again to make sure no wiring mistakes were made before turning on the power.
FUNCTION SETTING METHOD (for Wireless remote controller)
Entering the Function Setting Mode
While pressing the FAN button and SET TEMP. (
•
) simultaneously, press the RESET button to enter the function
setting mode.
STEP 1 Setting the Remote controller Custom code
Use the following steps to select the custom code of the remote controller. (Note that the air conditioner cannot receive a signal if the air conditioner has not been set for the matching costom code.) The custom codes that are set through this process are applicable only to the signals in the FUNCTION SETTING. For details on how to set
the custom codes through the normal process, refer to REMOTE CONTROLLER
Custom code SETTING.
Press the SET TEMP. (1. ) ( ) button to change the custom code between → → → Match the code on the display to the air conditioner custom code. (initially set to )
(If the custom code does not need to be selected, press the MODE button and
proceed to STEP 2.)
Press the TIMER MODE button and check that the indoor unit can receive signals 2. at the displayed custom code.
Press the MODE button to accept the custom code, and proceed to STEP 2.3.
The air conditioner custom code is set to A prior to shipment.
The remote controller resets to custom code A when the batteries in the remote controller are replaced. If you use a
custom code other than custom code A, reset the custom code after replacing the batteries. If you do not know the air conditioner custom code setting, try each of the custom codes ( → → → ) until you nd the code which operates the air conditioner.
STEP 2 Selecting the Function Number and Setting Value
Press the SET TEMP. (1. ) ( ) buttons to select the function numbe r. (Press the MODE button to switch between the left and right digits.)
Press the FAN button to proceed to setting the value. 2. Press the FAN button again to return to the function number selection.)
Press the SET TEMP. (3. ) ( ) buttons to select the setting value. (Press the MODE button to switch between the left and right digits.)
Press the TIMER MODE button, and START/STOP button, in the 4. order listed to conrm the settings.
Press the RESET button to cancel the function setting mode.5.
After completing the FUNCTION SETTING, be sure to turn off 6. the power and turn it on again.

FEATURES
Peak cut operation
z
Peak cut mode
Suppresses maximum capacity to perform energy-saving operation, preventing breaker tripping. This function operates by setting a peak current value and reducing the power consumption.
* Performance drops by reducing the power consumption preferentially.
Level 1 ... Suppresses the power consumption to almost 0% by stopping the compressor. Level 2 ... Suppresses the power consumption to 50% of the rated power consumption value. Level 3 ... Suppresses the power consumption to 75% of the rated power consumption value. Level 4 ... Suppresses the power consumption to the rated power consumption value (100%).
