OverviewIntroducing the 4‑Way Cassette FCU WindFree™, a ceiling cassette unit designed for concealed installation in commercial and residential interiors. The unit provides gradual, draft‑free conditioning and a low‑profile finish suitable for restaurants, offices, shops and living areas.
Features- WindFree™ Technology — The WindFree 4‑Way 900 x 900 cassette distributes air through 15,700 micro‑holes in the panel to produce 'Still Air', cooling spaces gradually without cold drafts.
- Optimised blades — Larger 84 mm blades extend the effective cooling range and improve air circulation for more uniform temperature distribution. Blades are detachable and washable for simplified maintenance and consistent airflow quality.
- Self‑Diagnosis — Integrated self‑diagnosis provides error codes and LED indicators to speed up fault identification and reduce service time.
Controls- Remote control with SmartThings — Remote operation via the SmartThings app enables on/off, mode selection, scheduling and energy monitoring (requires Wi‑Fi kit and compatible SmartThings account/app).
- SolarCell Remote Controller (optional) — Optional SolarCell remote charges via an integrated solar panel (no disposable batteries), offers USB‑C fast charging, a large OLED display and improved ergonomics.
Available capacities & powerAvailable cooling capacities: 6.0 kW, 7.2 kW, 9.0 kW, 10.0 kW. Power supply: Single phase (220–240 V, 50/60 Hz).
Disclaimers- 'Still Air' is defined as air movement below 0.15 m/s (no cold drafts).
- Comparative performance references relate to previous 4‑Way Cassette models.
- SmartThings control requires a Wi‑Fi kit and compatible mobile OS versions.
