FEATURES

Energy saving (AO A24LACL, AO A24LALL connection model)

High energy saving was realized by making the indoor unit and outdoor unit fan motor and compressor all DC and optimal design of the refrigerant cycle. Rank A was achieved in European energy rank.

Slim & compact design

In the case of bottom suction type, as seen from lower rear part.

Control Box united with main unit

One-touch operating and easy-to-install long-life filter (optional)

In addition to the slim height of 270 mm which is our sales point, further com-pactification is attained by reducing 65 mm from the width with the flanking control box embedded inside the chassis.

FUNCTION SETTING

Static pressure mode setting

Air flow, noise, etc. can be used under the optimum conditions by selecting the static pressure mode matched to the installation conditions.

Room temperature adjustment correction

Suitable room temperature control is performed by changing the room temperature correction value by simple remote control operation to match the conditions under which the air conditioner is installed.

Auto restart

The units restart automatically when the current was returned even when there was a power interruption during operation.
