Features

No cold drafts

The WindFree 4‑Way 900 x 900 Cassette directs air through 15,700 micro‑holes in the panel. These micro‑holes are essential for creating a type of airflow called “Still Air”¹ which cools the room gradually and noticeably without drafts¹.

Optimised blades

The larger optimised blades² (84 mm WindFree 4-Way Cassette), facilitate a wider cooling range and improved air circulation within the room. This advanced technology also cools the space much faster leaving no zone untouched. These blades are detachable and can be washed easily with water to remove dust or debris that has collected on them, therefore allowing for optimal quality of airflow that in turn helps maintain a cleaner environment.

Self-Diagnosis

The WindFree 4‑Way Cassette’s Self‑Diagnosis function alerts you to malfunctions straight away, which means that you can quickly arrange a service repair visit. And an error code and LED light enable engineers to easily identify the cause of any failure, helping to reduce the time it takes to diagnose and fix the problem.

Remote Control with SmartThings

Your clients can control the temperature at home, anytime and anywhere. The SmartThings App³ enables users to remotely control their air conditioner. With just the touch of a button, users can turn the air conditioner on or off, select the cooling mode, schedule the air conditioner’s operation and monitor its power consumption.

SolarCell Remote Controller (Optional)

Samsung introduces the SolarCell Remote controller to its air conditioning line-up as an option. The new SolarCell remote controller focuses on innovative charging, slim design and easy usability features. The SolarCell remote controller does not need batteries; instead a solar panel is integrated on the back of the remote controller that allows charging by exposing it under direct light. A single, fully charged battery can last up to two years, making it an economical alternative to disposable batteries. In addition, there is also a USB-C port on the bottom of the remote control for fast charging. It has better grip, easier button controls, large OLED display and it is lightweight⁴.

2. Samsung testing compares the WindFree 4-Way and WindFree 4-Way 600 x 600 Cassette to a previous 4-Way Cassette type air conditioner.

3. A Wi-Fi connection with a Wifi Kit MIM-H04EN and Samsung SmartThings application account are required. Requires iOS 10.0 or later & Android 5.0 or later.

4. Compared to the conventional infrared remote controller for example, the AR-EH03.
