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 does not star t. Operation starts and maintains the room •
temperature at 10°C when the temperature drops below 10°C.

FUNCTION SETTING12.
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 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 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 SELECTING THE REMOTE
CONTROLLER SIGNAL CODE.
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, 4.
in the order listed to conrm the settings.
Press the RESET button to cancel the function setting 5.
mode.
After completing the FUNCTION SETTING, be sure to turn 6.
off the power and turn it on again.

Press the MODE button again to return to the clock display. The signal code will 4.
be changed.
If no buttons are pressed within 30 seconds after the signal code is displayed, the system returns to the original
clock display. In this case, start again from step 1.
The air conditioner signal code is set to A prior to shipment.
Contact your retailer to change the signal code.
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

Wired remote
controller
UTY- RNNY M
Unit control is performed by
wired remote controller.
Apple-catechin
lter
UTR- FA13 -1
Fine dust, invisible mold
spores, and harmful
microorganisms are absorbed
onto the lter by static
electricity, and further growth
is inhibited and deactivated
by the polyphenol ingredient
extracted from apples.
Ion
deodorisation
lter
UTR- FA13 -2
The lter deodorizes by
powerfully decomposing
absorbed odors using the
oxidizing and reducing effects
of ions generated by the ultra
ne-particle ceramic.
External
connect kit
UTY-X W ZX
Use to connect with various
peripheral devices and air
conditioner PC board.
