When using the wireless remote controller, point it towards the receiver on the indoor unit.
If the remote controller is operated within approximately 2 minutes after power is supplied to
the indoor unit, the indoor unit may beep twice as the unit is performing the initial automatic
check.
The indoor unit beeps to confirm that the signal transmitted from the remote controller has
been received. Signals can be received up to approximately 7 meters in a direct line from the
indoor unit in an area 45° to the left and right of the unit. However, illumination such as fluores-
cent lights and strong light can affect the ability of the indoor unit to receive signals.
If the operation lamp near the receiver on the indoor unit is blinking, the unit needs to be in-
spected. Consult your dealer for service.
Handle the remote controller carefully! Do not drop the remote controller or subject it to strong
shocks. In addition, do not get the remote controller wet or leave it in a location with high hu-
midity.
To avoid misplacing the remote controller, install the holder included with the remote controller
on a wall and be sure to always place the remote controller in the holder after use.
Two AAA batteries
Insert the negative (–)
end of each battery first.
Install the batteries in
the correct directions

ŶAccording to a set temperature, cooling operation starts if the room
temperature is too hot and heating operation starts if the room
temperature is too cold.
ŶDuring automatic operation, if the room temperature changes and
remains 1.5 °C or more above the set temperature for 3 minutes, the
air conditioner switches to cool mode. In the same way, if the room
temperature remains 1.5 °C or more below the set temperature for
3 minutes, the air conditioner switches to heat mode.
Cool mode 3 minutes (switches
from heating to cooling)
Set temperature +1.5°C

Set temperature -1.5°C

ŶBecause the room temperature is automatically adjusted in order to
maintain a fixed effective temperature, cooling operation is performed
a few degrees warmer and heating operation is performed a few
degrees cooler than the set room temperature once the temperature is
reached (automatic energy-saving operation).
