NAMES AND FUNCTIONS OF REMOTE CONTROL UNIT

REMOTE CONTROLLER
This controls the operation of the indoor unit. Signal range to reach indoor unit is about 7 meters. If inverter lamp is used, the range of control may be shorter. This unit can be fixed on a wall using the fixture provided. Before fixing it, make sure the indoor unit can be controlled from the remote controller.

COOLING OPERATION

Use the device for cooling when the outdoor temperature is 21 ~ 43°C. If indoors humidity is very high (over 80%), some dew may form on the air outlet grille of the indoor unit.

NOTE
HI fan speed mode selected
When unit has been operating for a long period of time and the difference between remote controller setting temperature and actual room temperature is continuously large, the fan speed may increase causing higher air blow sound. During the time, cooling capacity will be maximized. If the air blow sound causes any discomfort, please select “AUTO” or other than “HI” fan speed.

SILENT OPERATION

NOTE:
Under SILENT mode operation and quiet environment, phenomena like flowing noise of refrigerant in the refrigerating cycle may occur, but this is normal for the operation.
