Floor Temperature Sensor

  Detects average temperature 

of fl oor surface.

Human Detection Sensor

   Detects human movement. 

●

  

Since the Human Detection Sensor enables to detect the heat transfer, it can not only detect human but it can 

detect coexisting high-temperature objects.

  (For example, movement of animals, swinging head freestanding type infrared heater, etc.)
●

 

 The

 

Human Detection Sensor cannot detect human presence in some cases listed below.

 

• 

In case of less human movement

 

• 

In case of less exposure of the skin

 

• 

In case of more than 30°C of room temperature

 

• 

In case of greasy dirt, soot, dust, scratches adhered to a surface of Human Detection Sensor

●

  

Since the Floor Temperature Sensor measures the average temperature of the fl oor surface in the detection area, 

there is a possibility that the sensor is infl uenced by a heat source existed in the range of the detection area. When 
taking advantage of the function with the infl uence of the fl oor temperature (circulate function), pay attention to the 
placement of a heat source. 

Criteria of human detection sensor area

•  Installation height of indoor unit 2.7 m : Approx. ø7 m 

•  Installation height of indoor unit 4 m : Approx. ø8 m 

• Installation height of indoor unit 5 m : Approx. ø9 m 

Approx. ø7 - 9 m

Detection area of 

Human Detection 

Sensor

1 m above fl oor visual range

Installation 

height: 

2.7 - 5 m

Detection area of Floor Temperature Sensor

●  The further human is away from the Human Detection Sensor, the larger the movement of human body is required 

to be detected.

●  A place where the blind angle of the Human Detection Sensor cannot detect human.

●  If there is a heat source or cooling unit in the detection area, the sensor cannot occasionally detect properly.

●  The Floor Temperature Senor detects within the sensor area of the Human Detection Sensor.

If the Operating Instructions supplied with the remote controller in use does not give descriptions of the ECONAVI 

function, direct airflow / indirect airflow function, circulation function and external device interlock function, the in-use 

remote controller is not available to these functions.
