3-in-1 Air Conditioner with WiFi Daikin Perfera 2.0 kW 7000 BTU

The Daikin Perfera 3x1 multisplit air conditioner with WiFi, 2.0 kW + 2.0 kW + 2.0 kW is a climate control system designed to provide cooling and heating in three rooms using a single outdoor unit. This set is made up of three Daikin Perfera FTXM20B indoor units of 2.0 kW each, equivalent to approximately 7,000 commercial BTU/h per room, and a Daikin 3MXM52A8 outdoor unit with 5.2 kW of nominal cooling capacity.

Thanks to its Inverter technology, reversible heat pump with R-32 refrigerant and WiFi connectivity, it lets you enjoy a comfortable temperature all year round. Each indoor unit has independent temperature control, fan speed adjustment and scheduling, adapting to the needs of each room.

The Daikin Perfera range stands out for incorporating advanced comfort and air treatment technologies, such as Flash Streamer, two-zone intelligent motion sensor, Comfort+ and 3D airflow distribution. Its ultra-quiet operation, at just 19 dB(A) in the quietest cooling mode, makes this system especially suitable for bedrooms, children's rooms, studies and offices.

This multisplit configuration allows three rooms with similar thermal needs to be air conditioned using a single outdoor unit, reducing the space required on facades, balconies and terraces compared with installing three independent split systems.

Daikin Perfera 3x1 air conditioner composition

This multisplit set is made up of the following equipment:

• 3 Daikin Perfera FTXM20B indoor units: wall-mounted units with a cooling class of 2.0 kW each, equivalent to approximately 6,824 BTU/h per unit, commercially 7,000 BTU. They include WiFi connectivity, quiet operation, intelligent motion sensor and Flash Streamer technology.
• 1 Daikin 3MXM52A8 outdoor unit: Inverter multisplit heat pump with three independent refrigerant connections, R-32 refrigerant and a combined nominal reference capacity of 5.2 kW in cooling and 6.8 kW in heating.
• 3 Daikin ARC466A93 wireless remote controls: one for each indoor unit, allowing individual control of temperature and the main air conditioning functions.

The 3x1 multisplit configuration allows three rooms to be air conditioned using a single outdoor unit, while maintaining individual control of each room and reducing the space occupied by the installation.

Main advantages of the Daikin Perfera 3x1 air conditioner

Independent air conditioning for three rooms

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

For example, one 2.0 kW FTXM20B unit can be installed in the master bedroom, another in a second bedroom and the third in a study or children's room.

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.

In addition, only the indoor units in the rooms that need air conditioning can be used, avoiding running equipment in rooms that are not being used.

Smart WiFi control via Daikin Onecta

The three Daikin Perfera FTXM20B indoor units feature WiFi connectivity so you can manage the air conditioning from a smartphone or tablet using the Daikin Onecta app.

This app allows you to control each indoor unit individually from anywhere with an Internet connection, making climate management easier even when you are not at home.

Its main functions include:

• Independent on/off: allows each indoor unit to be switched on or off from the mobile device.
• Individual temperature control: makes it easy to set a different temperature in each room.
• Operating mode selection: cooling, heating, fan and dehumidification.
• Fan speed adjustment: allows the airflow to be adapted to the needs of each room.
• Weekly scheduling: makes it easy to set custom schedules.
• Energy management: provides access to energy monitoring and saving functions compatible with the app.
• Voice control: allows the main functions to be managed through compatible assistants such as Amazon Alexa and Google Assistant.

WiFi connectivity provides flexibility of use, as it allows operating schedules to be adapted to the occupants' routines and rooms to be prepared before arriving home.

Flash Streamer technology to improve air quality

The Daikin Perfera FTXM20B indoor units incorporate Flash Streamer technology, an air treatment system developed by Daikin that uses high-speed electron discharge to help reduce certain allergens and odours present in the environment.

This technology is complemented by different filtration elements:

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

The combination of these technologies helps improve indoor air quality and provides a more comfortable environment during operation.

To maintain the performance of the filtration system, it is recommended to clean and maintain the filters regularly according to the manufacturer's instructions.

Two-zone intelligent motion sensor

The Daikin Perfera indoor units include a two-zone intelligent motion sensor that detects where people are in the room and adjusts the direction of the airflow to reduce direct drafts on occupants.

When no presence is detected for a certain period, the unit can automatically activate an energy-saving setting that helps reduce electricity consumption.

This system improves thermal comfort and optimises air conditioner operation without the need to constantly adjust settings from the remote control.

Even air distribution with Comfort+ and 3D airflow

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

In cooling mode, the flaps can direct air towards the upper part of the room to reduce direct drafts. In heating mode, they adapt the distribution to promote comfortable circulation of warm air.

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

These technologies help reduce temperature differences and provide greater thermal comfort during operation.

Ultra-quiet operation at just 19 dB(A)

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

In heating mode, each unit can operate with a minimum sound pressure of 20 dB(A).

These levels make the system especially suitable for bedrooms, children's rooms, studies and other spaces where discreet air conditioning is desired.

The quiet mode reduces the indoor fan speed when rest or room tranquillity is the priority.

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, within the capacity limits of the multisplit system.
• Econo mode: limits the unit's maximum electricity consumption.
• Quiet mode: reduces fan speed to minimise operating noise.
• Night mode: adapts operation during rest hours.
• Dehumidification: helps reduce ambient humidity.
• Fan mode: allows room air to circulate without activating cooling or heating.
• Weekly scheduling: makes it easy to set custom schedules.
• Automatic restart: restores the settings after a power outage.
• Automatic fan control: adjusts the speed according to the air conditioning needs.
• Automatic swing: distributes air through flap movement.
• Energy saving in standby: a function that helps reduce consumption when the unit remains in standby mode, depending on the installation settings.

Cooling and heating capacity of the Daikin Perfera 3x1 set

The system combines three 2.0 kW class indoor units, whose sum of individual capacities is 6.0 kW. However, the combined nominal cooling capacity when the three indoor units operate simultaneously is 5.2 kW, determined by the performance of the Daikin 3MXM52A8 outdoor unit.

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

Cooling capacity

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

• Minimum cooling capacity: 1.8 kW.
• Nominal cooling capacity: 5.2 kW, approximately 17,740 BTU/h.
• Maximum cooling capacity: 6.5 kW, according to Spanish technical table 4D139804D.
• Minimum electrical consumption in cooling: 0.37 kW.
• Nominal electrical consumption in cooling: 1.07 kW.
• Maximum reference electrical consumption in cooling: 2.06 kW.
• Calculated nominal EER: approximately 4.86.

When the three indoor units operate simultaneously under nominal conditions, the cooling capacity distribution is:

• First FTXM20B 2.0 kW unit: 1.73 kW.
• Second FTXM20B 2.0 kW unit: 1.73 kW.
• Third FTXM20B 2.0 kW unit: 1.73 kW.

The manufacturer presents the individual capacities rounded, so the sum may differ slightly from the combined nominal capacity of 5.2 kW.

When only one or two indoor units are operating, the available capacity adapts to the demand of the rooms in use, always within the system limits.

Heating capacity

The reversible heat pump allows the system to be used during the colder months, with a combined nominal heating capacity of 6.8 kW.

According to Daikin's official technical table for the 20 + 20 + 20 classes, the values are:

• Minimum heating capacity: 1.3 kW.
• Nominal heating capacity: 6.8 kW, approximately 23,200 BTU/h.
• Maximum heating capacity: 8.0 kW.
• Minimum electrical consumption in heating: 0.32 kW.
• Nominal electrical consumption in heating: 1.39 kW.
• Maximum reference electrical consumption in heating: 2.13 kW.
• Calculated nominal COP: approximately 4.89.

The nominal distribution of heating capacity when the three indoor units operate simultaneously is:

• First FTXM20B 2.0 kW unit: 2.27 kW.
• Second FTXM20B 2.0 kW unit: 2.27 kW.
• Third FTXM20B 2.0 kW unit: 2.27 kW.

The capacity and consumption data above come from Daikin's official tables for the 20 + 20 + 20 combination with the 3MXM52A8 outdoor unit. The values correspond to standardised conditions and may vary depending 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 the air conditioning needs, avoiding unnecessary starts and stops and promoting efficient electricity consumption.

As an efficiency reference, Daikin's official multisplit combination tables published in November 2025 indicate for the 20 + 20 + 20 combination with the 3MXM52A8 outdoor unit a classification of A+++ in cooling and A++ in heating for average climate.

The reference seasonal values published for this combination are:

• Reference energy class in cooling: A+++.
• Reference energy class in heating for average climate: A++.
• Reference SEER: 8.51.
• Reference SCOP for average climate: 4.61.
• Design capacity in cooling (Pdesignc): 5.2 kW.
• Design capacity in heating for average climate (Pdesignh): 5.0 kW.
• Normalised annual reference consumption in cooling: 214 kWh/year.
• Normalised annual reference consumption in heating: 1,516 kWh/year.

SEER and SCOP indicators express the seasonal energy performance of air conditioning equipment. The higher the value, the greater the amount of thermal energy provided per unit of electrical energy consumed under standardised calculation conditions.

The annual consumption figures indicated are standardised values used to compare equipment and do not represent the guaranteed actual consumption of a home. This will depend on insulation, selected temperatures, operating hours and climate conditions.

Important regarding energy efficiency: the A+++, A++, SEER 8.51 and SCOP 4.61 values come from Daikin's official documentation for the 20 + 20 + 20 combination with the 3MXM52A8 outdoor unit, but the tables do not expressly identify the FTXM-B generation indoor units. For this reason, they should be considered reference values until the certified energy label for the three FTXM20B units in this set is available.

Refrigerant connections of the Daikin Perfera 3x1

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

Indoor unit connection diameters

The three FTXM20B indoor units have the same refrigerant connection diameters:

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

Outdoor unit connection diameters

The Daikin 3MXM52A8 outdoor unit has three refrigerant ports with the following diameters:

• 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 FTXM20B indoor units have 3/8" gas connections, while ports B and C on the outdoor unit have a diameter of 1/2". For this reason, the corresponding refrigerant reducers will be required to adapt the 1/2" gas connections to 3/8" piping.

The distribution planned by Daikin's manual for three class 20 indoor units is as follows:

• Port A: one FTXM20B unit, with 3/8" gas piping and 1/4" liquid piping, without the need for reduction.
• Port B: one FTXM20B unit, using reducers 2 and 4 to adapt the 1/2" gas connection to 3/8".
• Port C: one FTXM20B unit, using reducers 2 and 4 to adapt the 1/2" gas connection to 3/8".

Daikin includes a reducer set among the standard accessories of the outdoor unit. The installer must check that all the necessary adapters are available to correctly complete the two circuits that require reduction.

It will also be necessary to respect the correspondence between the refrigerant and electrical connections of each indoor unit, following the manufacturer's official connection diagram.

Maximum pipe lengths and permitted height differences

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

• Maximum pipe length per indoor unit: 25 metres.
• Total maximum 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 above: 15 metres.
• Maximum height difference between indoor units when the outdoor unit is above: 7.5 metres.
• Maximum height difference between outdoor and indoor units when the outdoor unit is below: 7.5 metres.
• Maximum height difference between indoor units when the outdoor unit is below: 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 the calculation and rounding procedure established by Daikin.
• Maximum total refrigerant charge allowed: 2.2 kg.

For example, an installation can be designed with refrigerant runs of 10, 15 and 20 metres, giving a total length of 45 metres. This layout complies with Daikin's maximum length limits, although the height differences and the rest of the technical conditions must also be checked.

When the 30 metres covered by the factory charge are exceeded, 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 additional grams, following the procedure established by the manufacturer.

The refrigerant length is calculated by taking the liquid pipe outbound run between the units as the reference, without counting the gas pipe length of the same circuit again.

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 piping: minimum insulation thickness of 10 mm.
• 3/8" gas piping: minimum insulation thickness of 13 mm.
• 1/2" gas connections when used: minimum insulation thickness of 13 mm.
• Material: polyethylene foam suitable for refrigeration installations, with a minimum thermal resistance of 120 °C.
• Refrigerant piping: seamless copper, phosphorus deoxidised and suitable for R-32 refrigerant.
• Minimum wall thickness for 1/4", 3/8" and 1/2" piping: 0.8 mm, subject to applicable regulatory and pressure requirements.

When the ambient temperature exceeds 30 °C and relative humidity is above 80%, Daikin specifies a minimum insulation thickness of 20 mm to prevent surface condensation.

The installer must also check the condition of the refrigerant piping, condensate drainage, electrical supply and the necessary clearances around the outdoor unit.

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

The Daikin Perfera 3x1 multisplit with three 2.0 kW units and 7,000 commercial BTU each is especially suitable for homes and offices that need to air condition three rooms with similar thermal requirements.

A typical layout may consist of installing one FTXM20B unit in the master bedroom, another in a second bedroom and the third in a study, children's room or homework area.

As a commercial guideline, each 2.0 kW class unit may be suitable for rooms of approximately 12 to 20 m², depending on the building conditions and air conditioning needs.

These areas are indicative and do not replace a thermal load calculation. The actual air conditioning capacity will depend on insulation, orientation, ceiling height, glazed surfaces, occupancy and climate conditions.

It is also important to bear in mind that, when the three indoor units operate simultaneously, the available capacity is distributed according to the system's total capacity, 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 composition of this Daikin Perfera 3x1 set includes three FTXM20B 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 stated composition of the set. Depending on the characteristics of each home or premises, it will be necessary to have copper refrigerant piping, insulation, electrical and interconnection wiring, condensate drain piping, trunking, outdoor unit supports and fixing elements.

It will also be necessary to check the availability of the refrigerant reducers needed to adapt the gas connections of ports B and C on the outdoor unit, as well as verify the correspondence between the refrigerant and electrical circuits of the three indoor units.

The installation must comply with the maximum pipe lengths, height differences, power supply conditions and start-up instructions established by Daikin.
