 HOW TO OPERATE

<WIRELESS REMOTE CONTROL>

Press           MODE button.

The  range  of  operation  mode  is  displayed  according  to  the 
model of indoor unit.
Fresh  Air  DX  Assembly  (SAF-DX),  operation  in  dehumidifying 
mode is not possible.
Setting to dehumidifying mode will perform operation in cooling 
mode.
Every  time  the  button  is  pressed,  the  display  changes  in  the

(The  automatic  operation  can  be  selected  in  case  of  the  heat 
recovery system KXR only. The automatic operation cannot be 
selected in case of heat pump system KX.)

With  auto  operation, 
heating  and  cooling  is 
automatically  changed 
depending on difference 
between  the  setting 
temperature  and  room  
temperature.*

IN case of FDU-F
The  setting  temperature  of  the  remote  controller  indicates 
the  outdoor  temperature  while  operating  thermostat 
ON/OFF.

For the outdoor unit with Duct connected -High static pressure 
outdoor air processing unit (FDU-F) and Fresh Air DX Assembly 
(SAF-DX), operation in dehumidifying mode is not possible.
Setting to dehumidifying mode will perform operation in cooling 
mode.

The air filter uses the filter of the total heat exchanger.
Follow the instructions in the User’s Manual for the total heat exchanger.

This User’s manual addresses only a topic particular to this unit (more specifically, the 
underlined section).
For any other contents, refer to the User’s manual attached to the outdoor unit.
