Cooling Operation

1. Automatic Fan Speed
Odour Cut Control makes fan stop temporarily for 40 seconds at the beginning of unit operation or Thermostat-ON in order to
wash away odour ingredients from heat exchanger with dehumidifying water. Fan operation is repeated every 20 seconds at a
speed of "SLo" (Refer to the "Indoor Fan Control" chapter.) as the graph shown below.
2. Powerful
Unit is automatically operated in Quick Cooling (Fan speed "SHi": Refer to the "Indoor Fan Control" chapter.) in the initial 5
minutes of the operation and after that, switched to Chilly Cooling according to the symmetrical areas.
3. Low noise control
At setting of Fan Speed: "AUTO" (Refer to the "Indoor Fan Control" chapter.), if room temperature reaches a setting
temperature, fan speed will be reduced for the fan noise reduction.
4. Dew Condensation Prevention Control
The maximum frequency for Indoor Unit is decided by the Dew Condensation Prevention Control according to elapsed
operating times. Condition: Indoor unit fan speed is "Me-" or less.
Conditions resolutive
When remote controller setting temperature or fan speed setting is changed:
When 420 minutes elapsed:
5. Forced Cooling Operation
Fan speed will be "Hi" (Refer to the "Indoor Fan Control" chapter.) when the units is operated at Forced operation mode.

Dry Operation

In the cooling mode area, fan speed is the same as cooling operation mode. In the dry mode area, it is switched to "SLo". (Refer
to the "Indoor Fan Control" chapter.) In the Thermostat-OFF, fan stops 5.5 minutes and after that, operates at a speed of "SLo"
(Refer to the "Indoor Fan Control" chapter.). (At manual fan speed) At automatic fan speed operation, fan operates repeatedly
between 90-second stop and 20-second "SLo". At the beginning of unit operation and Thermostat-ON, fan stops 40 seconds.

Heating Operation

1. Hot Start and Cold Draft
At the beginning of unit operation, when indoor heat exchanger temperature is low, fan will be stopped. When the temperature
is getting high, the unit will be prevented from Cold Draft by increasing fan speed.
2. Automatic fan speed
At automatic fan speed setting, when the heat exchanger temperature is getting high, the unit will be prevented from Cold draft
by increasing fan speed as well as manual fan speed setting. In a fixed fan speed area, fan speed will be controlled to discharge
