NAMES AND FUNCTIONS OF REMOTE฀CONTROLLERREMOTE CONTROLLER
• This controls the operation of the indoor unit.
Signal range to reach air-conditioner is about 7 meters. If indoor lighting is controlled
electronically, the range of control may be shorter, in some cases, the control signal may not be
received.
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.
• Handle the remote controller with care.
Dropping it or getting it wet may compromise its signal transmission capability.

Set the desired FAN SPEED with the (FAN SPEED) button
(the display indicates the setting).
(AUTO) : The FAN SPEED is HI at first and varies to MED
(HI) : Economical as the room will become cool quickly.
(MED) : Quiet.
(LOW) : More quiet.
(SILENT) : Silent.
2
Set the desired room temperature with the TEMPERATURE
buttons (the display indicates the setting).
The temperature setting and the actual room temperature may
vary somewhat depending on conditions.
