Easy maintenance and always clean. Troublesome maintenance has been made easy.
Since the front panel is easy to remove, maintenance is also easy.
10°C HEAT Operation
z
The room temperature can be set to go no lower than 10 °C,
thus ensuring that the room does not get too cold when not occupied
Caution)
When the room temperature is higher than 10 °C, “10°C HEAT” operation will not start. Operation starts and maintains the room •
temperature at 10 °C when the temperature drops below 10 °C.

FUNCTION SETTINGS12.
INDOOR UNIT (Setting by remote controller)12-1.
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.
•
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 custom code if the air conditioner has not
been set for the custom 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 custum 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
