The 3x1 multisplit configuration allows three rooms to be air-conditioned using a single outdoor unit, reducing the space required on facades, balconies and terraces compared with installing three independent air conditioning systems.

Main advantages of the Daikin Perfera 3x1 air conditioner

Independent climate control for three rooms

The Daikin Perfera multisplit system allows the three indoor units to be controlled separately, adjusting temperature, fan speed and operating schedules according to the needs of each room.

For example, the 2.0 kW FTXM20B unit can be installed in a small bedroom or office, while the two 2.5 kW FTXM25B units can be used in larger bedrooms or other rooms with greater thermal requirements.

The three units can operate simultaneously, although they must work in the same general cooling or heating mode. It is not possible to cool one room while heating another.

Smart WiFi control via Daikin Onecta

The Daikin Perfera FTXM20B and FTXM25B indoor units feature WiFi connectivity so you can manage climate control from a smartphone or tablet using the Daikin Onecta app.

The app allows you to control each indoor unit individually from anywhere with an Internet connection.

Its main functions include:

• Individual on/off control of each indoor unit.
• Independent temperature adjustment for each room.
• Selection of cooling, heating, fan and dehumidification modes.
• Adjustment of fan speed and airflow distribution.
• Setting schedules and weekly programming.
• Control of the main functions through compatible voice assistants, such as Amazon Alexa and Google Assistant.

WiFi control makes it possible to adapt the air conditioner to the daily habits of the occupants and avoid unnecessary consumption in rooms that are not being used.

Flash Streamer technology to improve air quality

The Daikin Perfera indoor units incorporate Flash Streamer technology, designed to help reduce certain allergens and odours present in the air.

This technology is complemented by different filtration elements:

• Silver particle filter: helps capture certain allergens, such as pollen.
• Titanium apatite deodorising filter: helps reduce unpleasant odours.
• Air filter: traps dust particles present in the air circulating through the unit.

These technologies help improve indoor air quality and provide a more comfortable environment in air-conditioned rooms.

Two-zone intelligent motion sensor

The indoor units incorporate a two-zone intelligent presence sensor that detects the location of people within the room and adapts the direction of the airflow to avoid direct drafts on occupants.

When no presence is detected for a certain period, the system can automatically activate energy-saving operation, helping to reduce electricity consumption.

Even air distribution with Comfort+ and 3D airflow

Daikin's Comfort+ technology uses dual flaps to improve air distribution in the room and promote a more even temperature.

In addition, 3D airflow combines automatic vertical and horizontal movement to distribute cool or warm air throughout different areas of the room.

These functions help reduce temperature differences within the room and provide greater thermal comfort during operation.

Ultra-quiet operation at only 19 dB(A)

One of the main features of the Daikin Perfera range is its quiet operation. Both the FTXM20B indoor unit and the two FTXM25B units achieve a minimum sound pressure of 19 dB(A) in quiet cooling mode.

In heating mode, the three units can operate with a minimum sound pressure of 20 dB(A).

These sound levels make them especially suitable for bedrooms, children's rooms, offices and other spaces where discreet climate control is desired.

Comfort and energy-saving functions

The Daikin Perfera indoor units include different modes to adapt operation to the needs of each moment:

• Powerful mode: temporarily increases performance to reach the selected temperature more quickly.
• Econo mode: limits the unit's maximum electrical consumption.
• Quiet mode: reduces fan speed to minimise noise.
• Night mode: adapts operation during rest hours.
• Dehumidification: helps reduce ambient humidity.
• Fan mode: allows air to circulate in the room without activating cooling or heating.
• Weekly timer: makes it easy to set personalised operating schedules.

Cooling and heating capacity of the Daikin Perfera 3x1 set

The system combines one 2.0 kW class indoor unit and two 2.5 kW units, whose sum of individual capacities is 7.0 kW. However, the nominal combined cooling capacity when the three indoor units operate simultaneously is 5.2 kW, determined by the capacity of the 3MXM52A8 outdoor unit.

The available capacity is distributed among the indoor units depending on which ones are operating, the thermal demand and the environmental conditions.

Cooling capacity

According to Daikin's official tables for the 3MXM52A8 outdoor unit and the 2.0 + 2.5 + 2.5 kW class combination, the nominal reference values are:

• First FTXM25B 2.5 kW unit: 2.43 kW.
• Second FTXM25B 2.5 kW unit: 2.43 kW.

These values come from Daikin's official technical combination tables by power class for the 3MXM52A8 outdoor unit. The distributed capacities are shown rounded and actual performance will depend on indoor and outdoor temperatures, installation conditions and simultaneous operation.

Energy efficiency of the Daikin Perfera 3x1 air conditioner

The system uses Inverter technology to regulate compressor speed according to climate control needs, avoiding unnecessary starts and stops and promoting efficient electricity consumption.

The Daikin 3MXM-A8 multisplit range achieves energy efficiency classes of up to A+++ in cooling and A++ in heating, depending on the combination of indoor units installed and the manufacturer's commercial documentation.

Its main energy features include:

• Reference energy class of the range in cooling: up to A+++.
• Reference energy class of the range in heating: up to A++.
• Nominal cooling capacity of the set: 5.2 kW.
• Nominal heating capacity of the set: 6.8 kW.
• Technology: Inverter with Swing compressor.
• Refrigerant: R-32.
• Independent control: allows you to use only the rooms that need climate control.
• Econo mode: helps limit maximum electrical consumption.

SEER and SCOP indicators express the seasonal energy performance of the units. The higher their value, the greater the amount of thermal energy supplied per unit of electrical energy consumed under standardised calculation conditions.

Important: the final SEER, SCOP and energy class values depend on the exact combination of indoor units. The official documentation consulted does not provide a specific energy label for FTXM20B + FTXM25B + FTXM25B + 3MXM52A8, so the range efficiency values indicated above should not be interpreted as an energy certification for this set.

Refrigerant connections of the Daikin Perfera 3x1

The Daikin Perfera 3x1 multisplit air conditioner has three independent refrigerant circuits that connect the FTXM20B and FTXM25B indoor units to the 3MXM52A8 outdoor unit.

Connection diameters of the indoor units

The three indoor units have the same refrigerant connection diameters:

• FTXM20B 2.0 kW unit: 1/4" liquid connection (6.4 mm) and 3/8" gas connection (9.5 mm).
• First FTXM25B 2.5 kW unit: 1/4" liquid connection (6.4 mm) and 3/8" gas connection (9.5 mm).
• Second FTXM25B 2.5 kW unit: 1/4" liquid connection (6.4 mm) and 3/8" gas connection (9.5 mm).

Connection diameters of the outdoor unit

The Daikin 3MXM52A8 outdoor unit has three 1/4" liquid refrigerant ports, while the gas connection diameters are as follows:

• Port A: 1/4" liquid (6.4 mm) and 3/8" gas (9.5 mm).
• Port B: 1/4" liquid (6.4 mm) and 1/2" gas (12.7 mm).
• Port C: 1/4" liquid (6.4 mm) and 1/2" gas (12.7 mm).

Important about the connections: the three indoor units in this set have 3/8" gas connections, while ports B and C of the outdoor unit have a 1/2" diameter. For this reason, the corresponding 1/2" to 3/8" refrigerant reducers will be required to connect these two circuits correctly.

The outdoor unit includes a reducer set among its standard accessories, but the installer must check the availability of the necessary adapters and follow Daikin's established connection diagram.

Maximum pipe lengths and permitted height differences

To ensure proper operation of the Daikin Perfera 3x1 system, the installation must respect the maximum refrigerant pipe lengths and height differences established by Daikin.

• Maximum pipe length per indoor unit: 25 metres.
• Maximum total refrigerant pipe length: 50 metres, adding the three runs together.
• Minimum pipe length per indoor unit: 3 metres.
• Maximum height difference between outdoor and indoor units when the outdoor unit is installed higher: 15 metres.
• Maximum height difference between indoor units when the outdoor unit is installed higher: 7.5 metres.
• Maximum height difference between outdoor and indoor units when the outdoor unit is installed lower: 7.5 metres.
• Maximum height difference between indoor units when the outdoor unit is installed lower: 15 metres.
• Total length covered by the factory refrigerant charge: 30 metres of liquid piping.
• Additional refrigerant charge: 20 grams per additional metre when the total run exceeds 30 metres, applying Daikin's indicated calculation and rounding procedure.
• Maximum total refrigerant charge: 2.2 kg.

For example, it is possible to carry out an installation with refrigerant runs of 10, 15 and 20 metres, obtaining a total length of 45 metres. This distribution complies with the maximum lengths established by the manufacturer, although the height differences and the rest of the technical conditions must also be checked.

When exceeding the 30 metres covered by the factory charge, it will be necessary to calculate and add the corresponding amount of R-32 refrigerant. For a total length of 45 metres, the theoretical calculation would be 300 grams additional, before applying the manufacturer's rounding instructions.

Insulation of refrigerant piping

Daikin establishes specific requirements for the thermal insulation of refrigerant piping, in order to reduce energy losses and prevent condensation from forming.

• 1/4" liquid pipes: suitable insulation for cooling, with a recommended minimum thickness of 10 mm.
• 3/8" gas pipes: suitable insulation for cooling, with a recommended minimum thickness of 13 mm.
• Material: insulating foam suitable for refrigeration installations and the unit's operating temperatures.

The final insulation thickness must be determined according to environmental conditions and the specifications of the corresponding technical manual. In especially warm and humid environments, greater thicknesses may be necessary to prevent surface condensation.

What spaces is the Daikin Perfera 3x1 2.0 + 2.5 + 2.5 kW recommended for?

The Daikin Perfera 3x1 multisplit 2.0 + 2.5 + 2.5 kW is especially interesting for homes and offices that need to air-condition three rooms with different thermal demands.

A common layout may consist of installing the 2.0 kW FTXM20B unit in a small bedroom or office and the two 2.5 kW FTXM25B units in larger bedrooms.

As a commercial guideline, the 2.0 kW unit may be suitable for rooms of approximately 12 to 20 m², while the 2.5 kW units can be used in rooms of approximately 15 to 25 m². These areas are indicative and do not replace a thermal load calculation.

The actual area each unit can condition will depend on insulation, orientation, ceiling height, glazing area, occupancy and climatic conditions.

It should also be noted that when the three indoor units operate simultaneously, the available capacity is distributed according to the total system output, 5.2 kW in cooling and 6.8 kW in heating.

To ensure proper sizing, it is recommended that a professional calculate the cooling and heating needs of each room before installation.

Installation and required materials

The Daikin Perfera 3x1 set consists of one FTXM20B indoor unit, two FTXM25B indoor units and one 3MXM52A8 outdoor unit, together with their corresponding remote controls and the standard accessories supplied by the manufacturer.

The materials required for installation are not included in the set. Depending on the characteristics of each home or premises, copper refrigerant piping, insulation, electrical and interconnection wiring, condensate drain piping, trunking, outdoor unit supports and fixing elements will be required.

It will also be necessary to check the correct use of refrigerant reducers to adapt the gas connections of ports B and C of the outdoor unit and verify the correspondence between the refrigerant and electrical connections of each indoor unit.

The installation must respect the maximum pipe lengths, height differences, refrigerant connections and power supply conditions established by Daikin.

The installation must be carried out by qualified professionals certified to work with air conditioning equipment using fluorinated gases, in compliance with current regulations and the manufacturer's official technical instructions.
