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 to 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. •
* Before turning on the power of the indoor units, make sure the piping air-tight test and vacuuming
have been conducted .
* 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 Signal Code
Use the following steps to select the signal code of the remote controller. (Note that
the air conditioner cannot receive a signal code if the air conditioner has not been set
for the signal code.) The signal codes that are set through this process are applicable
only to the signals in The Function Setting. For details on how to set the signal codes
through the normal process, refer to REMOTE CONTROLLER SIGNAL CODE
SETTING.
Press the SET TEMP. (1.
) ( ) button to change the signal code between →
→
→ Match the code on the display to the air conditioner signal code. (initially
set to
)
(If the signal 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 signal code.
Press the MODE button to accept the signal code, and proceed to STEP 2.3.
The air conditioner signal code is set to A prior to shipment.
The remote controller resets to signal code A when the batteries in the remote controller are replaced. If you use a
signal code other than signal code A, reset the signal code after replacing the batteries.
If you do not know the air conditioner signal code setting, try each of the signal 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 conrm the settings.
Press the RESET button to cancel the function setting mode.5.
After completing The Function Setting, be sure to turn off the 6.
power and turn it on again.

CONTENTS OF FUNCTION SETTING
Follow the instructions in the Local Setup Procedure, which is supplied with the remote control, in •
accordance with the installed condition.
After the power is turned on, perform the Function Setting on the remote control.
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. •
1) Filter sign
2) Ceiling height
3) Cooler room temperature correction
4) Heater room temperature correction
5) Auto restart
6) Indoor room temperature sensor switching function
7) Remote controller signal code
8) External input control
9) Indoor unit fan control for energy saving
1) Filter sign
