9.6.2. Cooling Operation1. Automatic Fan SpeedOdour Cut Control makes fan stop temporarily for 40 seconds at the beginning of unit operation or Thermostat-ON in order towash away odour ingredients from heat exchanger with dehumidifying water. Fan operation is repeated every 20 seconds at aspeed of "SLo" (Refer to the “Indoor Fan Control” chapter.) as the graph shown below.2. PowerfulUnit is automatically operated in Quick Cooling (Fan speed "SHi": Refer to the "Indoor Fan Control” chapter.) in the initial 5minutes of the operation and after that, switched to Chilly Cooling according to the symmetrical areas.3. Low noise controlAt setting of Fan Speed: "AUTO" (Refer to the “Indoor Fan Control” chapter.), if room temperature reaches a settingtemperature, fan speed will be reduced for the fan noise reduction.4. Dew Condensation Prevention ControlThe maximum frequency for Indoor Unit is decided by the Dew Condensation Prevention Control according to elapsedoperating times. Condition: Indoor unit fan speed is "Me-" or less.CS-HE9DKE CS-HE12DKEMax. Frequency (A) (Hz) 35 54Max. Frequency (B) (Hz) 35 42Max.
