Split Systems Feature Glossary

Energy-saving Features

Dual-fans

Creates a comfortable environment with Hybrid Airflow, which combines air currents and velocities of different temperatures.

Human sensor (Energy Saving)

The air conditioner switches to operate on reduced power when it detects no human movement in the room.

Human sensor for saving/stop modes

The air conditioner switches to operate on reduced power or switches off when it detects no human movement in the room.

Economy mode

A thermostat setting is adjusted automatically according to the room temperature to avoid unnecessary cooling or heating.

Setting temperature range limitation

Sets the minimum and maximum limits on room temperature to establish the right balance between energy saving and comfortable environment.

Set temperature auto return

The set temperature automatically returns to the previous level.

Features for Comfort

Powerful heating

Maintains the rated heating capacity even when the outdoor temperature drops to -7°C.

Power diffuser

An additional louver is activated based on feedback from the monitoring sensors to quickly cool or warm the room.

Ideal for use in a server room

Connect 2 indoor units to make them operate in tandem in cooling mode even when the outdoor temperature is low.

Powerful mode

The air conditioner operates at the maximum airflow level and compressor speed to cool or warm the room quickly.

10ºC heating operation

The room temperature can be set to not go below 10°C so that the room will not become too cold when unoccupied.

Low noise mode

Reduces the noise level of an outdoor unit.

Auto changeover

The unit automatically switches between heating and cooling operations based on the set temperature and room temperature.

Vertical swing louver

The louver automatically swings up and down.

Automatic double swings

Activates complex swing action of the louver in both horizontal and vertical directions.

Automatic fan speed

Microprocessor automatically adjusts the fan speed and airflow according to changes in room temperature.

Auto restart

The unit automatically restarts in the previous operation mode when power returns after an outage.

Connectable fresh air duct

Takes in outside air by attaching a supplied duct to the fresh air knockout and an optional part.

Fresh air intake

Fresh air can be taken in from outside by a fan connected to an external control unit.

Connectable distributing duct

Supplied branch ducts can be attached to better distribute airflow.

Individual airflow direction control

Each louver of a 4-way cassette air conditioner can be controlled individually to provide comfortable airflow.

Cooling operation at 52°C

High cooling capacity is maintained even at an outdoor temperature of 52℃.

PM 2.5 filter

Equipped with a high-quality membrane filter designed to capture minuscule particulates.

Convenience Features

Auto-off timer

The unit automatically switches off when a predetermined time has elapsed after the timer is activated.

Sleep timer

Gradually changes the room temperature to maintain a comfortable sleeping environment.

Program timer

Sets the time for 1 of the following 4 options: On, Off, from On to Off, and from Off to On

Weekly timer

Sets different On/Off times for each day of the week.

Weekly & Temperature setback timer

Sets temperature for two sets of On/Off times and for each day of the week.

Filter sign

Indicates when the filter should be cleaned.

External error output

External On/Off input

Wireless LAN control

The optional Wireless LAN Adapter enables a smartphone or tablet to operate the air conditioner from anywhere inside or outside the house or building.

Clean Features

Plasma air clean

The electrostatic precipitator removes pollen and house dust from the air. The precipitator can be washed to keep it clean.

Filter auto clean

Dust collected by the air filter is automatically discarded. Routine disposal of dust stored in the dust box is required.

Ion deodorization filter

Deodorizes the air by decomposing absorbed odors using the oxidizing and odor-reducing effects of ions generated by ultra-fine-particle ceramic.

Apple-catechin filter

The Apple-catechin filter uses static electricity to remove fine particles and dust in the air.

Washable panel

The front panel can be removed easily and cleaned.

Installation

Automatic airflow adjustment

Determines the airflow level required in each application and adjusts the airflow volume automatically.

Drain pump equipped as standard

Blue fin

All-DC model
