   Operates in the designated human absence operating mode. 

   When setting the temperature for a shipment, energy 

saving operation continues under controlled temperature. 

   (For absence operating mode, see “NOTE” on page 10.)

*  If human is detected in absence operation mode, 

the operation condition is resumed depending on 

the amount of human activity.

Do not use ECONAVI function when only a disabled person or infant staying at home.

If a small movement of human body continues for a long time, Panel for cassette (ECONAVI type) 

recognizes human absence and air conditioner may sometimes stop operating. 

●

  

When setting the ECONAVI function, it is necessary to use the remote controller provided with the ECONAVI 

function.

●

  

ON / OFF setting of the ECONAVI function is available by the remote controller.

●

  

The time between the absence detected by the Human Detection Sensor and the start of absence operation can be 

set by the remote controller (At shipment: 1 hour or every 30 minutes between 30 min and 180 min can be available 

to change).

●

  

It is possible to choose from 4 types of absence operating mode by the remote controller.

  (1) Without setting 

Energy saving operation under controlled temperature continues.

   

 

 

 When a human is detected, the operation returns depending on the amount of human 

activity. (At shipment)

  (2) Standby mode 

Cooling, dry and heating operation are stopped and only fan (breeze) is operated.

   

 

 

 When a human is detected, the operation returns depending on the amount of human 

activity. 

  (3) Stop mode (No restart) 

 Operation is stopped. After stopped, no operation is restarted although human is 

detected.

  (4) Stop mode (Restart) 

 Operation is stopped. After stopped and when human is detected, the operation is 

restarted depending on the amount of human activity. 

●

  

Even though the targeted temperature is changed by the ECONAVI function, the set temperature displayed on the 

remote controller will not be changed.

●

  

Even though the operation is changed to fan operation mode due to the absence operation (standby mode), the 

operation mode displayed on the remote controller will not be changed.

●

  

When operating the multiple indoor units, the effect of energy saving will be decreased according to the room 

condition.

●

  

As for the setting method of the ECONAVI function, refer to the Operating Instructions of the remote controller.    

The Human Detection Sensor can detect the human presence and perform the Direct Airfl ow or Indirect Airfl ow 
function when the human is present within the detection area.

●

  

  Human presence: The air fl ow swings up and down around the human body in cooling/heating mode.

  Human absence: The air fl ow is directed to the fl oor according to the direction setup.
●

  

  Human presence: The fl ap is set in horizontal direction and the air fl ow is not directed toward the human body.

  Human absence: The air fl ow is directed to the fl oor according to the direction setup.

Airflow function is required.

● When only the ECONAVI function switched on, Direct Airflow / Indirect Airflow function can be operated. 

●  The setting of the Direct Airflow / Indirect Airflow function can be made by the remote controller according to each 

flap of the indoor unit.

●  This function does not guarantee that the air flow will direct toward the human body or not.

●  As for the setting method of the Direct Airflow / Indirect Airflow function, refer to the Operating Instructions of the 

remote controller.     

When the low fl oor temperature is detected by Floor Temperature Sensor in heating mode or high fl oor temperature is 
detected in cooling mode, the circulation function is operated in order to reduce the temperature irregularity between 
the surroundings of ceiling and fl oor. The circulation function is operated although the unit is in preparation for heating 
in the single split system. 

●  The circulation operation while heating is operated as 

shown below.

  • The air fl ow is automatically changed.
  • 

  is displayed on the remote controller.    

●  When the air conditioner detects human absence, 

set the air fl ow downward in cooling and heating 
mode. Then the unit starts reducing the temperature 
irregularity in a whole room.

  • 

  is displayed on the remote controller.    

●  When circulation operation fi nished or interrupted, 

the following operations are carried out.

  • The fan speed responds to the setting of fan speed.
  •  The air flow responds to the setting of air flow 

direction.    

  • 

  is not displayed on the remote controller.      

●  The circulation operation in preparing for heating 

(thermostat off) is operated as shown below.

  • Flap is positioned in horizontal.
  • 

  is displayed on the remote controller.    

●  When setting the circulation function, the remote controller provided with the circulation function is required.

● When only the circulation function switched on, the circulation function can be operated.

● ON/OFF setting of the circulation function can be made by the remote controller according to each indoor unit.

● If the operation mode/fan speed/air flow is changed during circulation operation, the circulation will be interrupted.

  The cases listed below will not carry out the circulation in heating mode.

   <When Human Detection Sensor is detecting human presence>

   •  When the air flow is not directed toward the human body (When setting the indirect airflow or airflow horizontally, 

etc.)

  • When the individual air flow is made at immobilized setting

  • When the specific operation mode setting is made (Defrosting or low discharge temperature) 

  • When setting the changes of the fan speed and air flow are prohibited by central control system

   • When the fan speed is fixed (No automatic air flow setting is made.)

  • When the auto flap setting is made

  <When Human Detection Sensor is not detecting human presence>

  • When the auto flap setting is made

● As for the setting method of the circulation function, refer to the Operating Instructions of the remote controller.
