FEATURES

Energy saving rank A

European energy ranking rank A achieved by all DCization and optimization of the refrigerant cycle

Quiet operation

Air flow mode can be set in 4 steps and more detailed air flow setting is possible  18 type: 32 dB / 24 type: 36 dB at operation in the Quiet mode

Filter sign

Dirtying of filter is detected by air conditioner operating time and the user is informed

ECONOMY operation

Operation that suppresses maximum power consumption is performed

Wired/wireless simultaneous use possible

Wired remote controller and wireless remote controller can be simultaneously used.

Flexible installation

FLOOR

CEILING

Double auto swing

Combination of up/down and right/left air direction swing allows three-dimensional air direction control. Since up/down air direction flaps operate automatically, according to the operating mode of the unit, it is possible to set the air direction based on the operating mode.

FLOOR / CEILING TYPE

AB A18-24L

Ceiling height (standard/high ceiling)

Air conditioner operation capacity (air flow) switching is possible as response to height of installation ceiling.

Cooling room temperature correction (Standard/low control)

Air conditioner control temperature can be switched to a little low as response to installation conditions.

Heating room temperature correction (Standard/low/slightly high/high control)

Air conditioning control temperature can be slightly adjusted as response to installation conditions.

Auto restart (ON/OFF)

ON/OFF of the function which automatically resets operation to the operation state before the power interruption at power recovery when there was a power interruption during operation can be selected.

Room temperature sensing function (ON/OFF) only at wired remote controller connection

Sensor which controls the room temperature can be selected in two types: "Indoor sensor only" or "Indoor sensor or wired remote controller sensor can be switched by remote controller operation".
