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, the 2.5 kW FTXM25B unit in a larger bedroom and the 3.5 kW FTXM35B unit in a living room or dining 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.

Smart WiFi control via Daikin Onecta

The Daikin Perfera FTXM20B, FTXM25B and FTXM35B 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.
• Access to the energy control functions available in the app.
• Control of the main functions through compatible voice assistants, such as Amazon Alexa and Google Assistant.

WiFi control allows the system to be adapted to the daily habits of the occupants, avoiding 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, which uses high-speed electron discharge to help reduce certain allergens and odours present in indoor air.

This technology is complemented by different filtration systems:

• Silver particle filter: helps capture certain allergens, 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 unit.

The combination of these technologies helps improve indoor air quality and provides a more comfortable environment in the 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 reduce direct drafts on occupants.

When no presence is detected for a certain period, the unit 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 from just 19 dB(A)

One of the main features of the Daikin Perfera range is its quiet operation. The FTXM20B, FTXM25B and FTXM35B indoor 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 a suitable option 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 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 air to circulate in the room without activating cooling or heating.
• Weekly programming: makes it easy to set personalised operating schedules.
• Auto restart: restores the settings after a power outage.
• Temperature limitation: allows regulation limits to be set to avoid excessively high or low temperatures.

Cooling and heating capacity of the Daikin Perfera 3x1 set

The system combines three indoor units of 2.0, 2.5 and 3.5 kW class, whose sum of individual capacities is 8.0 kW. However, the combined nominal cooling capacity when the three indoor units operate simultaneously is 6.8 kW, determined by the performance of the 3MXM68A8 outdoor unit.

Refrigerant connections of the Daikin Perfera 3x1

The Daikin Perfera 3x1 multisplit air conditioner has three independent refrigerant circuits connecting the FTXM20B, FTXM25B and FTXM35B indoor units to the 3MXM68A8 outdoor unit.

Connection diameters of the indoor units

All three indoor units have the same refrigerant connection diameters:

• Daikin FTXM20B 2.0 kW: 1/4" liquid connection (6.4 mm) and 3/8" gas connection (9.5 mm).
• Daikin FTXM25B 2.5 kW: 1/4" liquid connection (6.4 mm) and 3/8" gas connection (9.5 mm).
• Daikin FTXM35B 3.5 kW: 1/4" liquid connection (6.4 mm) and 3/8" gas connection (9.5 mm).

Connection diameters of the outdoor unit

The Daikin 3MXM68A8 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 on the outdoor unit have a 1/2" diameter. For this reason, 1/2" to 3/8" refrigerant reducers will be required to connect these two circuits correctly.

The Daikin manual identifies reducers 2 and 4 to adapt the 1/2" gas connections to 3/8" piping.

The outdoor unit includes a reducer set among its standard accessories. The installer must check that the necessary adapters are available and respect the correspondence between the refrigerant and electrical connections of each indoor unit.

Maximum pipe length and permitted height differences

To ensure the correct 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.
• 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 Daikin's calculation and rounding procedure.
• Maximum permitted total 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 respects the maximum pipe limits established by the manufacturer, although the height differences and other 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, following the procedure established by Daikin.

The refrigerant length is measured by taking the liquid pipe run between the units as a reference, without adding 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.

• 1/4" liquid pipes: thermal insulation suitable for cooling.
• 3/8" gas pipes: thermal insulation suitable for cooling.
• Recommended material: polyethylene foam with a thermal resistance of at least 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" diameters: 0.8 mm, subject to applicable regulatory and pressure requirements.

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

The installer must check the insulation of each circuit according to the environmental conditions, as well as the correct condensate drainage and the necessary clearances around the outdoor unit.

Which spaces is the Daikin Perfera 3x1 2.0 + 2.5 + 3.5 kW recommended for?

The Daikin Perfera 3x1 multisplit 2.0 + 2.5 + 3.5 kW is especially interesting for homes and offices that need to condition three rooms with different thermal requirements.

A common layout may consist of installing the 2.0 kW FTXM20B unit in a small bedroom or office, the 2.5 kW FTXM25B in a medium-sized bedroom and the 3.5 kW FTXM35B in a living room, dining room or large bedroom.

As a commercial guideline, the 2.0 kW unit may be suitable for rooms of approximately 12 to 20 m², the 2.5 kW unit for rooms of around 15 to 25 m² and the 3.5 kW unit for spaces of approximately 25 to 35 m².

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

It should also be noted 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 advisable for a professional to 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, one FTXM25B indoor unit, one FTXM35B indoor unit 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 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 availability of refrigerant reducers to adapt the gas connections of ports B and C, as well as verify the correspondence between the refrigerant and electrical connections of each indoor unit.

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

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

With its ability to condition three rooms, independent WiFi control, Inverter technology, quiet operation and advanced air treatment technologies, the Daikin Perfera 3x1 multisplit air conditioner FTXM20B + FTXM25B + FTXM35B + 3MXM68A8 offers a versatile climate control solution for enjoying cooling and heating all year round.
