NOTE :
• Specications are based on the following conditions.
Cooling : Indoor temperature of 80°F (26.67°C) DB / 67°F (19.44°C) WB, and outdoor temperature of 95°F (35°C) DB / 75°F (23.9°C) WB. Heating : Indoor temperature of 70°F (21.11°C) DB / 59°F (15°C) WB, and outdoor temperature of 47°F (8.33°C) DB / 43°F (6.11°C) WB. Pipe length : 24ft.7in (7.5m), Height difference:0 m. (Outdoor unit-Indoor unit)
• The protective function might work when using it outside the operation range.

*2: Thes e are the measured values in the ma nufacturer’s ane choic ch amber.
Because of the sur roundin g sound env ironmen t, the soun d levels measured in ac tual inst allati on condi tions might be higher than the s pecied values here.

10-1. INDOOR UNIT (Setting by remote controller)

WALL MOUNTED TYPE RIWH18-36A
• 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 Custom Code
Use the following steps to select the custom 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 matching 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 custom codes through the normal process, refer to "REMOTE CONTROLLER
CUSTO M CODE".
1. Press the SET TEMP. ( ) ( ) 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.)
2. Press the TIMER MODE button and check that the indoor unit can receive signals
at the displayed custom code.
3. Press the MODE button to accept the custom code, and proceed to STEP 2.
WALL MOUNTED TYPE
RIWH18-36A
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
1. Press the SET TEMP. ( ) ( ) buttons to select the function
number.
(Press the MODE button to switch between the left and right
digits.)
2. Press the FAN button to proceed to setting the value.
Press the FAN button again to return to the function number
selection.)
3. Press the SET TEMP. ( ) ( ) buttons to select the setting
value.
(Press the MODE button to switch between the left and right
digits.)
4. Press the TIMER MODE button, and START/STOP button,
in the order listed to conrm the settings.
5. Press the RESET button to cancel the function setting
mode.
6. After completing the FUNCTION SETTING, be sure to turn
off the power and turn it on again.

REMOTE CONTROLLER CUSTOM CODE SETTING
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 custom code.)
1. Press the START/STOP button until only the clock is displayed on the remote
controller display.
2. Press the MODE button for at least ve seconds to display the current custom
code (initially set to ).
3. Press the SET TEMP. ( ) ( ) button to change the custom code between →
