Daikin Emura is a wall-mounted R32 family for room heating and cooling. It has five current single-split pairs. The final indoor suffix selects matt white (W), silver (S) or matt black (B) without changing the paired capacity class.
Current single-split pairs
| Class | Indoor code before finish suffix | Outdoor unit | Nominal cooling / heating | SEER / SCOP | Cooling / heating class |
|---|---|---|---|---|---|
| 20 | FTXJ20A2V1B |
RXJ20A5V1B |
2.0 / 2.5 kW | 8.75 / 5.15 | A+++ / A+++ |
| 25 | FTXJ25A2V1B |
RXJ25A5V1B |
2.5 / 2.8 kW | 8.74 / 5.15 | A+++ / A+++ |
| 35 | FTXJ35A2V1B |
RXJ35A5V1B |
3.4 / 4.0 kW | 8.73 / 5.15 | A+++ / A+++ |
| 42 | FTXJ42A2V1B |
RXJ42A2V1B |
4.2 / 5.4 kW | 7.50 / 4.60 | A++ / A++ |
| 50 | FTXJ50A2V1B |
RXJ50A2V1B |
5.0 / 5.8 kW | 7.33 / 4.60 | A++ / A++ |
For example, the complete white class-25 indoor code is FTXJ25A2V1BW; silver ends S and black ends B. No functional meanings are defined for the A2V1B and A5V1B segments, so each remains intact.
Cabinet, sound and installation differences
Every indoor unit is 900 × 305 × 212 mm. Cooling sound pressure in silent/high modes rises from 19/39 dB(A) on class 20 to 24/46 dB(A) on class 50.
Classes 20, 25 and 35 use an 840 × 552 × 350 mm outdoor cabinet and allow 20 m of pipe with a 15 m level difference. Classes 42 and 50 use a 954 × 734 × 408 mm cabinet and extend those limits to 30 m and 20 m. The manufacturer maximum fuse size is 10 A for class 20 and 13 A for the other four.
Controls and multi-split use
The current family supports Onecta control. Compatible multi-split equipment can connect up to five indoor units, but that is a separate system schedule with its own outdoor code and permitted combinations. The five rows above are single-split pairs.
