  • Page 5: Cooling Operation

    1. COOLING OPERATION 1-1 COOLING CAPACITY CONTROL A sensor (room temperature thermistor) built in the indoor unit body will usually perceive difference or variation between a set temperature and present room temperature, and controls the operation frequency of the compressor. * If the room temperature is 6°C higher than a set temperature, the compressor operation frequency will attain to maximum performance.
  • Page 6: Heating Operation

    2. HEATING OPERATION 2-1 HEATING CAPACITY CONTROL A sensor (room temperature thermistor) built in the indoor unit body will usually perceive difference or variation between a set temperature and present room temperature, and controls the operation frequency of the compressor. * If the room temperature is lower by 6°C than a set temperature, the compressor operation frequency will attain to maximum performance.

  • Page 18: Human Sensor

    20. HUMAN SENSOR The Human sensor functions by pressing SENSO R  button on the remote controller. When the sensor detects that there is no one in the room for 20 minutes or more,  it automatically changes the operation as below s ettings. When someone comes back into the room, the human sensor will detect this, and automatically revert to the original settings. (Table 16) Mode Cooling/ Dry  Heating Target temperature     Setting temp.+2℃    Setting temp.- 4℃ ( Application range )   Vertical angle 90°(Side view) Horizontal angl e 100°(Top view)  7 m 7 m 90° 50° 50° The sensor unit should detect when the human body (estimate: 100cmX30cm) or the object  °C which has more than 4  temp, difference from the background and are crossed with  1.0m/s speed in front of the sensor unit. 21.
