Samsung WindFree mini cassette · updated October 26, 2026

The WindFree mini cassette: one ceiling tile, no drafts.

Q: What ceiling does it need?

A standard 2 × 2 ft drop-ceiling grid, at least 2.5 m off the floor as a rule, with room for a 9 13/16 in tall body above it. The opening is 580 to 585 mm square, per Samsung.

Q: Does it have WindFree mode?

Yes, in cooling only: the louvers close and air comes through thousands of micro-holes, at under 0.15 m/s, per Samsung. A humidity sensor in the panel limits the mode when the air is very humid.

Q: For a business?

Yes, if the drop ceiling is at least 2.5 m above the floor. It takes one 2 × 2 ft tile, blows four ways, and Samsung offers an optional occupancy sensor, the MCR-SMDU.

Q: How cold can it heat?

Down to -25 °C (-13 °F), per Samsung, with high heating capacity at -20 °C (-4 °F). At -25 °C, NEEP lists up to 6,400, 7,000 and 15,400 BTU/h for the 9,000, 12,000 and 18,000.

Q: Can fresh air be connected to it?

Yes: the body has a knock-out for outside air, with a booster fan, per Samsung. Samsung publishes neither its size nor the airflow. A duct to another room, on the other hand, does not apply to WindFree models.

Q: Is a remote included?

No. Samsung sells the controls separately: a wired wall control, or a wireless remote. The panel already has the display and the infrared receiver, and the remote is also used to set up Wi-Fi.

Q: Can it go on a multi-zone?

Yes: Samsung lists it among the heads compatible with FJM Premium multi-zone. The LogisVert amount then goes to the system. We confirm the combination in the quote.

Q: Is Wi-Fi included?

Per the submittal, the Wi-Fi adapter is built into the PC4SUFMUNW panel, for the SmartThings app; Samsung’s web page still mentions an adapter sold separately. We confirm it for your unit in the quote.

Q: Is a cassette under an attic eligible for LogisVert?

Hydro-Québec excludes indoor units installed outside the insulation envelope, for example in the attic or roof space. If the cassette body ends up in an unheated attic, the install falls in that case: we check the location during the visit.

Q: Why does the 9,000 get no LogisVert when it heats well?

Hydro-Québec first requires 12,000 BTU/h in cooling. ENERGY STAR certifies the 9,000 cassette at 9,100 BTU/h: it is not on the list, even though it gives 9,700 BTU/h at -8 °C, more than the other CAC 9,000s.

It takes the place of one 2 × 2 ft tile in a drop ceiling 2.5 m up or more, per Samsung. Its panel holds the display, the Wi-Fi and a humidity sensor; in cooling, WindFree mode blows at under 0.15 m/s. The best SEER2 of Samsung’s three CAC formats, at every size. LogisVert: $1,284 (12,000) and $1,872 (18,000).

01 · Which size?

The 9,000 delivers 9,700 BTU/h at -8 °C, yet no LogisVert.

For Hydro-Québec, what counts first is cooling: 12,000 BTU/h minimum. The 9,000 falls short, even though it heats well. Pick a size: models, AHRI number, certified heat and the math.

02 · Where it goes

One tile, four directions, and the best SEER2 of the three.

2 × 2 ft format

Designed for a standard drop-ceiling grid, without getting in the way of the tiles next to it, per Samsung. 620 mm (24 3/8 in) square panel.

The family’s best SEER2

22.00 on the 9,000 and 12,000, per ENERGY STAR: the highest of Samsung’s three CAC Premium units.

Four directions

Air leaves all four sides of the panel: a good option in the middle of an open room or a shop.

WindFree in summer

In cooling, air leaves at under 0.15 m/s in WindFree mode, per Samsung. The mode is not used in heating.

03 · From tile to panel

One tile, a 580 mm opening, and 2.5 m to the ceiling.

As a rule, Samsung doesn’t allow the mini cassette less than 2.5 m above the floor. Slide to your ceiling height, then follow the install, from tile to panel.

Ceiling height: 2.70 m

2.0 kgRoom size and R-32

Above 1.836 kg of R-32 in the system, Samsung sets a minimum room area: at a 2.5 m height, 5.23 m² at 2.0 kg and 6.27 m² at 2.4 kg. Only the 18,000 gets there, past 16.5 m of line (our math).

Fresh airYes, through a knock-out

A knock-out takes outside air, with a booster fan, per Samsung. A duct to another room does not apply to WindFree models.

Not allowedNo boat, no vehicle

The manual rules out a ship or a vehicle, such as a campervan.

Simplified illustration.

05 · Four directions

Set the blades one by one. Or switch to WindFree.

The mini cassette blows in four directions, and each blade has its own angle. Switch to WindFree, in cooling: air then comes through the panel’s micro-holes.

Mode

Blade

Blade angle: 45°

Samsung: four outlets, with blades set one by one, at the same or different angles, between 32° and 65°. In WindFree mode, offered in cooling only, the blades close and air comes through thousands of micro-holes in the panel, at under 0.15 m/s.

Source: samsunghvac.com, WindFree Mini 4-Way Cassette page (32-65° blades, cooling only); submittal 02132025A (thousands of micro-holes, 0.15 m/s). Arrow length: illustration, not a measured throw.

06 · Summer humidity

Very humid air: the cassette holds WindFree back.

In WindFree mode, the louvers close and air seeps out through the micro-holes. When the air is very humid, a sensor in the panel limits that mode to prevent condensation, per Samsung. Pick the mode and the weather.

The mode

The room air

WindFree: running

Louvers closed: air seeps out through thousands of micro-holes in the panel, under 0.15 m/s.

WindFree: held back by the sensor

The panel’s humidity sensor limits WindFree mode to prevent condensation. Samsung does not publish the humidity threshold.

WindFree: cooling only

In heating, the cassette blows through its open louvers: WindFree mode exists in cooling only, per Samsung.

Did you know: below 0.15 m/s, air counts as “still air” under ASHRAE 55-2013, Samsung notes. With its humidity sensor, the cassette also sets its coil temperature by the dew point, the Samsung submittal says.

Source: Samsung WindFree Mini 4-Way Cassette page: “WindFree™* operation is available in cooling mode only”, panel humidity sensor that restricts WindFree in high humidity, 0.15 m/s and ASHRAE 55-2013; submittal 02132025A (louvers closed, thousands of micro-holes; coil set by the dew point). Humidity threshold: not published by Samsung.

07 · Option: occupancy sensor

Nobody in the room? With its sensor, the cassette knows.

Samsung offers an occupancy sensor for the mini cassette, the MCR-SMDU, sold separately. Depending on who’s there, it turns the unit off or changes its set point. Watch a day go by, or tap an hour.

Example: an office day (made-up schedule)

Per Samsung, the sensor also learns your occupancy patterns, to cut run time between occupied and unoccupied periods.

Did you know: of Samsung’s three CAC Premium units, only the mini cassette has an occupancy sensor in its accessory list. Samsung publishes neither its range, its delay nor the set-point change.

Source: Samsung WindFree Mini 4-Way Cassette page: the “Motion Detection Sensor (MDS)” turns the unit off or changes its set point by occupancy and learns occupancy patterns; “Use of MDS is optional (sensor sold separately)”; submittal 02132025A (MCR-SMDU); Slim Duct and Console submittals (no occupancy sensor in their accessories). Schedule: made-up example.
