The air conditioner starts the operation in the Demo mode as described below when 2 minutes have elapsed after the 
protection control was started subsequent to the confirmation of communication error.  
(At this time, a strong warning sound is emitted for 3 minutes if the test run memory is “incomplete”.) 
 
Condition to stop the mode 
The operation is stopped by turning off the air conditioner on the remote control or pressing the EMERGENCY 
OPERATON switch during the Demo mode. 
(“TIMER” LED flashes.)

1  Conditions to start the mode 

The infrared sensor check mode starts when all of the following conditions are met: 

o 

The infrared sensor error is not being detected. 

o 

Not in Demo mode. 

o 

An error of Error Level 20 or higher is not present. 

o 

The signal for infrared sensor check is received. (Long-press the “AUTO COMFORT” button on the 
remote control for 10 seconds) 

 

2  Conditions to end the mode 

The infrared sensor check mode ends when any of the following conditions is met: 

o 

A signal other than the signal for infrared sensor check is received; or the Auto OFF/ON button is 
pressed → The signal received is followed. 

o 

5 minutes have elapsed since the signal for infrared sensor check was received → The mode is stopped. 

o 

The infrared sensor error is confirmed → The mode is stopped. 

o 

An error of Error Level 20 or higher has occurred → Follow the processing of each error.

3  Descriptions of the mode 

Every time the signal for infrared sensor check is received, the fixed detection is performed at a different 
human activity sensor angle. The result is displayed on LED every 3 seconds. 

 

Operation mode

Panel 

Ordinary operating position (It opens even if the mode signal received is “OFF”) 
Every time the signal for infrared sensor check is received, the position is shifted in the sequence of 
“Front   Left  Right  Front …” 
It starts operation from the front position when the check mode starts.

 Conditions in which detection is not allowed 

o  For 65 seconds after the infrared sensor is powered ON. 
o  While the human detection sensor STM is in operation and for 10 seconds after the human activity sensor 

STM turns off.

 Operation command by HA and ON timer is not valid during check mode. 

(OFF mode continues even after the check mode stops at the expiry time.) 

  During ECONAVI operation, the sunlight sensor detects sunlight intensity coming through windows and 

differentiates between sunny and cloudy or night to further optimize energy saving by adjusting the temperature. 

  Sunlight judgment is as following. 
 

 

  The sunlight intensity will to reset to zero (no sunlight condition) when 

o  Each time ECONAVI is activated. 
o  Setting temperature is changed. 
o  Operation mode is changed (exception interchanging COOL ↔ DRY). 
o  Open the Front Panel (Front Panel switch open).

  Based on sunlight sensor output voltage, the sunlight intensity value will be computed and logged to sunlight 

intensity database. 

  The sunlight sensor sensitivity could be adjusted: 
 

 

 

  Function MENU button: 

1  Selection of installation location. 
2  Selection of indicators’ brightness. 
3 ECONAVI 

indicator 

OFF. 

4  Selection of Contrast of LCD on remote. 

  According to sunlight intensity over a period of time, the system will analyze the ambient condition is sunny, 

cloudy or night. 

 

 

52 

  Operation details (to check, press ECONAVI button for 10 sec). 

o  The sunlight sensor check mode will be operated for 5 minutes. 
o  During check mode, the ON and OFF timer will be memorized but it operation be ignored. 
o  During check mode, if the sunlight sensor check code is retransmitted, the 5 minutes counter will be reset. 
o  During check mode, if sunlight sensor detected the sunlight intensity value above minimum level, the 

ECONAVI indicator turns ON. Else if sunlight sensor detected sunlight intensity value below minimum level, 
the ECONAVI indicator is OFF. 

  To disable sunlight sensor check mode 

o  After check mode is ended (5 minutes counter elapsed), press AUTO OFF/ON button at indoor unit. 
o  If the sunlight sensor detected sunlight intensity is at abnormal range, the check mode will be ended. 

Please check for error code. 

 Abnormality 

detection: 

o  When ECONAVI is ON, if the sunlight intensity value below minimum level continuously for 24 hours, the 

sunlight sensor disconnection error counter will increase by 1 time. If the ECONAVI is OFF, the 24 hours 
timer will be reset, but the sunlight sensor disconnection error counter will not be reset. 

  Error Code judgment 

o  When sunlight sensor disconnection error counter reached 15 times. H70 occurred. 
o  No TIMER indicator or ECONAVI indicator blink. 

  When error code happened, the unit is able to operate without sunlight sensor.
