  • Page 45: Operation And Control

    12 Operation and Control 12.1. Basic Function Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating mode, the microcomputer maintains the set temperature by measuring the temperature of the environment and performing temperature shifting.
  • Page 46 12.1.5. Automatic Operation • This mode can be set using remote control and the operation is decided by remote control setting temperature, remote control operation mode, indoor intake air temperature and outdoor air temperature. • During operation mode judgment, indoor fan motor (with speed of Lo-) and outdoor fan motor are running for 30 seconds to detect the indoor intake and outdoor air temperature.

  • Page 47: Quiet Operation (Cooling Mode/Cooling Area Of Soft Dry Mode)

    B. Feedback control • Immediately after the fan motor started, feedback control is performed once every second. • During fan motor on, if fan motor feedback 2550 rpm or < 50 rpm continue for 10 seconds, then fan motor error counter increase, fan motor is then stop and restart.
