12.10   Cooling Overload Control 

  Pipe temperature limitation / restriction. 

o

  Detects the outdoor pipe temperature and carry out restriction / limitation below (Limit the compressor 

operation frequency) 

o

  The compressor stops if outdoor pipe temperature exceeds 61°C. 

o

  If the compressor stops 4 times in 20 minutes, Timer LED blinks (“F95” indicated: Outdoor high pressure rise 

protection) 

12.11   Freeze Prevention Control 

  When indoor heat exchanger temperature is lower than 0°C continuously for 6 minutes, compressor will stops 

operation. 

  Compressor will resume its operation 3 minutes after the indoor heat exchanger is higher than 13°C. 

  At the same time, indoor fan speed will be higher than during its normal operation. 

  If the indoor heat exchanger temperature is higher than 13°C for 5 minutes, the fan speed will return to its normal 

operation. 

12.12   Freeze Prevention Control 2

o

  Timer LED blinks and “H99” indicated 

12.13   Dew Prevention Control 

  To prevent dew formation at indoor unit discharge area. 

  This control will be activated if: 

o

  Cooling mode or Quiet mode is activated. 

o

  Remote control setting temperature is less than 25°C. 

o

  Fan Speed is at CLo or QLo. 

o

  Room temperature is constant (±1°C) for 30 minutes. 

o

  Compressor is continuously running. 

  Fan speed will be adjusted accordingly in this control. 

o

  Fan speed will be increased slowly if the unit is in quiet mode but no change in normal cooling mode.
