10°C HEAT Operation



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 HE AT” operation does not start. 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. •

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 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

find 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
number.
(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 4.
the order listed to confirm the settings.

Press the RESET button to cancel the function setting mode.5.

After completing the FUNCTION SETTING, be sure to turn 6.
