- The following drawing explains the principle of fan speed control for cooling 46
- Within this range the airflow rate is automatically controlled when the fan setting button is set to automatic 46
- In case of inverter units the microcomputer automatically sets the temperature and fan settings the difference between the room temperature at startup and the temperature set by the microcomputer is divided into two zones then the unit operates in the dry mode with an appropriate capacity for each zone to maintain the temperature and humidity at a comfortable level 47
- Programme dry function 47
- Programme dry function removes humidity while preventing the room temperature from lowering since the microcomputer controls both the temperature and air flow volume the temperature adjustment and fan adjustment buttons are inoperable in this mode 47
- Automatic operation 48
- Night set mode 49
- A microcomputer in an indoor unit carries out a sampling every 20 msec and if it detects 10 cycles of the wave in one second in total corresponding to 20msec 10 100msec it judges human is in the room as the motion signal is on 50

- Intelligent eye 50
- Processing 1 detection method by intelligent eye 50
- Si04 306 main functions 50
- The motions for example in cooling 50
- This is the function that detects existence of humans in the room by a human motion sensor intelligent eye and reduces the capacity when there is no human in the room in order to save electricity 50
- This sensor detects human motion by receiving infrared rays and displays the pulse wave output 50
- When a microcomputer doesn t have a signal from the sensor in 20 minutes it judges that nobody is in the room and operates the unit in temperature sifted 2 c from the set temperature cooling 2 c higher dry 1 c higher and auto according to the operation mode at that time 50
