Daikin Perfera 3x1 Air Conditioner with WiFi 2.5 kW 9000 BTU

The Daikin Perfera 3x1 multisplit air conditioner with WiFi, 2.5 kW + 2.5 kW + 2.5 kW is an HVAC system designed to provide cooling and heating in three rooms using a single outdoor unit. This set is made up of three Daikin Perfera FTXM25B indoor units of 2.5 kW each and one Daikin 3MXM68A8 outdoor unit with 6.8 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 and scheduling, adapting to the needs of each room.

The Daikin Perfera range stands out for incorporating advanced 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 an especially attractive option for bedrooms, children's rooms, studies and offices.

This multisplit configuration allows you to air condition three rooms with similar thermal needs, using a single outdoor unit while maintaining individual control of each space.

Daikin Perfera 3x1 air conditioner composition

This multisplit set is made up of the following equipment:

• 3 Daikin Perfera FTXM25B indoor units: wall-mounted units with a cooling class of 2.5 kW each, equivalent to approximately 8,530 BTU/h per unit, commercially 9000 BTU. They feature WiFi, quiet operation, intelligent motion sensor and Flash Streamer technology.
• 1 Daikin 3MXM68A8 outdoor unit: Inverter multisplit heat pump with three independent refrigerant connections, R-32 refrigerant and a nominal capacity of 6.8 kW in cooling and 8.6 kW in heating for the 25 + 25 + 25 class combination.
• 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 reduces the space required on façades, balconies and terraces compared with installing three independent split systems, as it uses a single outdoor unit to supply the three indoor units.

Main advantages of the Daikin Perfera 3x1 air conditioner

Independent climate control for three rooms

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

For example, one 2.5 kW FTXM25B unit can be installed in the master bedroom, another in a second room 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 climate control can be switched on, avoiding the operation of units in rooms that are not being used.

Smart WiFi control via Daikin Onecta

The three Daikin Perfera FTXM25B indoor units feature WiFi connectivity so you can manage climate control 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 you to turn each indoor unit on or off from your mobile device.
• Individual temperature control: makes it easy to select a different temperature in each room.
• Operating mode selection: cooling, heating, fan and dehumidification.
• Fan speed adjustment: allows you to adapt the airflow 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 you to manage the main functions through compatible assistants such as Amazon Alexa and Google Assistant.

WiFi connectivity provides flexibility, as it allows you to adapt operating schedules to the occupants' routines and prepare the rooms before arriving home.

Flash Streamer technology to improve air quality

The Daikin Perfera FTXM25B indoor units incorporate Flash Streamer technology, an air treatment system developed by Daikin and designed 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.
• 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 systems helps improve indoor air quality and provides a more comfortable environment during operation.

To maintain filtration performance, it is recommended to clean the filters regularly and follow the manufacturer's maintenance instructions.

Two-zone intelligent motion sensor

The Daikin Perfera indoor units include a two-zone intelligent motion sensor that detects the location of people 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 even temperature throughout the room.

In cooling mode, the unit can direct air towards the upper part of the room to reduce direct drafts. In heating mode, it adapts the airflow to promote a comfortable distribution 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 within the room and provide greater 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 FTXM25B 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 climate control is desired.

In addition, 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 electrical 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 air to circulate in the room without activating cooling or heating.
• Weekly scheduling: makes it easy to set custom schedules.
• Auto restart: restores the settings after a power outage.
• Automatic fan control: adjusts the speed according to climate control needs.
• Automatic swing: distributes air through flap movement.

Cooling and heating capacity of the Daikin Perfera 3x1 set

The system combines three 2.5 kW indoor units, whose individual capacities add up to 7.5 kW. However, the combined nominal cooling capacity when the three indoor units operate simultaneously is 6.8 kW, determined by the performance of the Daikin 3MXM68A8 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.

Refrigerant connections of the Daikin Perfera 3x1

The Daikin Perfera 3x1 multisplit air conditioner has three independent refrigerant circuits that connect the FTXM25B indoor units to the 3MXM68A8 outdoor unit.

Indoor unit connection diameters

The three FTXM25B indoor units have the same refrigerant connection diameters:

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

Outdoor unit connection diameters

The Daikin 3MXM68A8 outdoor unit has three refrigerant ports with the following diameters:

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

Important about the connections: the three FTXM25B indoor units have 3/8" gas connections, while ports B and C on the outdoor unit have a 1/2" diameter. For this reason, the corresponding refrigerant reducers will be required to adapt the 1/2" gas connections to 3/8" piping.

The port distribution provided in Daikin's manual for three class 25 indoor units is as follows:

• Port A: one FTXM25B unit, with 3/8" gas piping and 1/4" liquid piping, without the need for reduction.
• Port B: one FTXM25B unit, using reducers 2 and 4 to adapt the 1/2" gas connection to 3/8".
• Port C: one FTXM25B 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 for 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 length and permitted height differences

To ensure 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.
• Maximum total refrigerant piping 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 length exceeds 30 metres, applying Daikin's specified calculation and rounding procedure.
• Maximum total permitted refrigerant charge: 2.4 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 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 calculation would be 300 additional grams, following the manufacturer's procedure.

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

Insulation of refrigerant piping

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

• 1/4" liquid pipes: minimum insulation thickness of 10 mm.
• 3/8" gas pipes: 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 of 1/4" and 3/8" pipes: 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 refrigerant piping conditions, condensate drainage, electrical supply and the necessary clearances around the outdoor unit.

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

The Daikin Perfera 3x1 multisplit with three 2.5 kW units and 9000 BTU commercial rating 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 FTXM25B unit in the master bedroom, another in a second bedroom and the third in a study, children's room or study area.

As a commercial guideline, each 2.5 kW class unit may be suitable for rooms of approximately 15 to 25 m², depending on the property's conditions and the simultaneous use of the other units.

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

It is also important to note that when the three indoor units operate simultaneously, the available power is distributed according to the system's total capacity, 6.8 kW in cooling and 8.6 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 proposed composition for this Daikin Perfera 3x1 set consists of three FTXM25B indoor units and one 3MXM68A8 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, copper refrigerant piping, insulation, electrical and interconnection wiring, condensate drainage piping, trunking, outdoor unit supports and fixing elements will be required.

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.

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

Installation must be carried out by qualified professionals accredited to work with climate control equipment using fluorinated gases, in compliance with current regulations and the manufacturer's official technical instructions.
