Three heads: is your trio in Samsung’s table?

Pick each room’s head. The tool looks the trio up in all four units’ tables. With three heads, when a unit refuses, it’s because the total is too high.

One head per room: pick each size
Room 1
Room 2
Room 3

Sizes come from the load calculation for each room, done at the visit. Here you see what Samsung’s combination table accepts, unit by unit.

The bigger the living room head, the smaller the bedrooms must be, except on the 36,000, which has room up to 48,000 BTU/h of heads. With a 24,000 living room head, the 30,000 leaves the bedrooms only 7,000 + 7,000 or 7,000 + 9,000; the 36,000 offers eight. The plan cycles on its own; tap a pair to see it. Exact sizes come from each room’s load calculation, at the visit.

Source: three-head tables in Samsung FJM Premium submittals (02142025A): each pair is a table row where the living room head is the biggest of the three. Head widths: FJM technical data book Ver. 1.2. Illustrative plan.

04 · 3 ports, 3 heads

The 20,000 has three ports. Here, it fills them all.

The AJ020DXS3CG is the only three-port FJM Premium. With three heads it’s full: five combinations in the table, with heads from 7,000 to 12,000. Pick a trio.

With three heads on the 20,000, the heads never add up to less than the unit’s index: 21,000 to 27,000 BTU/h, for an index of 21. The percentages are our math; Samsung publishes none.

05 · The heads

Three rooms, three ways to deliver air: wall, console, cassette.

With three heads, each room can have its own family. For example: a 7,000 wall head in a bedroom, a 9,000 console under a window, a 9,000 mini cassette in a drop ceiling. 7,000 + 9,000 + 9,000 = 25,000: that total is in all four units’ tables. Samsung notes that restrictions apply by head type, so we confirm it in the quote.

Source: Samsung FJM Premium submittals (02142025A), compatibility matrix (“** Restrictions apply”); Samsung model lists by family; slim duct manual DB68-12926A (one room only).

06 · The layout

Three heads, three lines, one outdoor unit.

Three lines leave the same unit. Switch between wall heads and a mix of families: each room keeps its own line and setting.

Illustration. Ports and limits: Samsung FJM Premium submittals (02142025A); start-up: installation manual DB68-13175A (“Pipe Checking Operation”, automatic addressing). Restrictions apply by head type: we check it in the quote.

07 · 230 ft for three

Three lines, 230 ft in all: the third one gets what’s left.

Each head can sit 82 ft from the outdoor unit. But three times 82 is 246 ft, and Samsung caps the total at 230. Slide the three lengths.

With three heads, the limit that matters isn’t just the farthest head any more: it’s the sum. Three times 82 ft is 246 ft; with two lines at 82 ft, the third stops at 66 ft (20 m), our math. At least 10 ft per head, against noise and vibration, per Samsung. We measure all three runs at the visit. The example plays on its own until you touch a slider.

Source: Samsung FJM Premium submittals (02142025A): “Max. Individual Line Set Length 82 ft”, “Max. Line Set Length (total) 230 ft”; installation manual DB68-13175A (10 ft minimum; do not add refrigerant).

08 · Basement, main floor, upstairs

One head per floor, basement to upstairs: 25 ft apart at most.

One head in the basement, one on the main floor, one upstairs: it works as long as the highest and lowest stay within 25 ft (7.5 m) of each other. Set the floor-to-floor height and how high each head goes.

Grade

The main floor doesn’t count toward the gap: only the highest and lowest heads do. With one head per level at the same height, floors must be 12.3 ft apart or less (our math). Samsung asks to mount heads 5.9 ft or more off the floor. Illustrative house: main floor at grade, main-floor head at 7 ft.

09 · R-32 and bedroom size

Three bedrooms, one R-32 charge: each needs at least 117 to 125 sq ft.

Samsung’s manual sets a minimum floor area for any room that holds an R-32 unit, based on the system’s charge. An FJM Premium holds 3.1 kg for all its heads: for a wall head, the table gives 117 sq ft at 3.0 kg and 125 sq ft at 3.2 kg. Slide your bedrooms’ dimensions.

Dashed: 125 sq ft (11.6 m²), the table’s 3.2 kg row for a wall head. Drawn to scale.

Bedroom 2

Bedroom 3

Samsung’s table is “Calculated in accordance with UL 60335-2-40 Annex GG”; the charge that counts is the whole system’s, 109.3 oz (3.1 kg) on every FJM Premium. Samsung doesn’t say whether the heads’ leak detector changes the area required, and local rules may add to it. The same table asks for 352 to 375 sq ft for a floor console, and 84.4 to 90.1 sq ft for a ceiling head at 2.5 m. For comparison, a Max Heat 9,000 single-zone holds 34.0 oz (0.96 kg), under the 1.836 kg “no restriction” row.

One triple-zone, one AHRI number: $1,584 to $2,760.

Hydro-Québec’s math starts from the installed combination’s certified capacity at -8 °C. Three heads or two, a multi-zone has one outdoor unit and one AHRI number: one amount for the system. Pick a unit.

16 · Frequently asked questions

What people ask about Samsung triple-zones.

7,000 × 3 and 9,000 × 3: all four units. 12,000 × 3: the 30,000 and 36,000. 15,000 × 3: the 36,000 only. 18,000 × 3 (54,000): not in any table.

No. With two 7,000s that’s 29,000 BTU/h of heads, and the 20,000 stops at 27,000. You need at least the 24,000 (7,000 + 7,000 + 15,000 or 7,000 + 9,000 + 15,000).

On the 24,000, 30,000 and 36,000, yes: four ports for three heads. The 20,000 has three ports, all in use.

Yes, per the R-32 table in Samsung’s manual. For a wall head it gives 117 sq ft (10.9 m²) at 3.0 kg of refrigerant and 125 sq ft (11.6 m²) at 3.2 kg; the FJM holds 3.1 kg, however many heads it has. Samsung doesn’t say how to read 3.1 kg: we measure each room at the visit.

No. 3 × 82 = 246 ft, and Samsung allows 230 ft in total. With two lines at 82 ft, the third stops at 66 ft (20 m), our math.

Yes, as long as the highest and lowest heads stay within 25 ft (7.5 m) of each other, and within 49 ft (15 m) of the outdoor unit, per Samsung.

No. The math uses the system’s AHRI number, and a multi-zone has only one: $1,584 (20,000) to $2,760 (36,000) with wall heads, per Hydro-Québec’s list.

One room on its own? A wall unit or a console.

One more room, off the multi-zone circuit: a single-zone Samsung wall unit or console. And for a house with ducts, the Hylex central system.
