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 the temperature, fan speed and operating schedules according to the needs of each room.

For example, the two 2.0 kW FTXM20B units can be installed in small bedrooms, children's rooms or home offices, while the 3.5 kW FTXM35B unit is intended for a larger bedroom or a living 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 and FTXM35B indoor units feature built-in WiFi connectivity for managing 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.
• Fan speed adjustment.
• Scheduling and weekly programming.
• Control of the main functions through compatible voice assistants, such as Amazon Alexa and Google Assistant.

WiFi control makes it easier to adapt operation to the daily habits of occupants and avoid unnecessary energy use 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 odors present in indoor air.

This technology is complemented by different filtration elements:

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

The combination of these technologies helps improve indoor air quality and provide a more comfortable environment in the conditioned rooms.

Two-zone intelligent motion sensor

The indoor units include a two-zone intelligent presence sensor that detects the location of people within 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 system can automatically activate energy-saving operation, helping reduce electricity consumption.

Even air distribution with Comfort+ and 3D airflow

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

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

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

Ultra-quiet operation of only 19 dB(A)

One of the main features of the Daikin Perfera range is its quiet operation. Both FTXM20B indoor units and the FTXM35B unit achieve a minimum sound pressure of 19 dB(A) in silent 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, home 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 output to reach the selected temperature more quickly.
• Econo mode: limits the unit's maximum power consumption.
• Silent mode: reduces fan speed to minimize 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 personalized operating schedules.
• Automatic restart: restores settings after a power outage.
• Temperature limitation: allows setting regulation limits to avoid excessively high or low temperatures.

Cooling and heating capacity of the Daikin Perfera 3x1 set

The system combines two 2.0 kW class indoor units and one 3.5 kW class unit, whose sum of individual capacities is 7.5 kW. However, the combined nominal cooling capacity when the three indoor units operate simultaneously is 5.2 kW, determined by the performance of the 3MXM52A8 outdoor unit.

The available power is distributed among the indoor units depending on which ones are operating, the thermal demand 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 two FTXM20B indoor units and the FTXM35B unit to the 3MXM52A8 outdoor unit.

Connection diameters of the indoor units

All three indoor units have the same refrigerant connection diameters:

• First FTXM20B 2.0 kW unit: 1/4" liquid connection (6.4 mm) and 3/8" gas connection (9.5 mm).
• Second FTXM20B 2.0 kW unit: 1/4" liquid connection (6.4 mm) and 3/8" gas connection (9.5 mm).
• FTXM35B 3.5 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 on 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.

Daikin's manual identifies reducers 2 and 4 to adapt the 1/2" connections to 3/8" gas piping. The outdoor unit includes a reducer set among its standard accessories, but the installer must verify that all necessary adapters are available for the installation.

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

Maximum pipe length and permitted height differences

To ensure 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 meters.
• Maximum total refrigerant piping length: 50 meters, adding the three runs together.
• Minimum pipe length per indoor unit: 3 meters.
• Maximum height difference between outdoor and indoor units when the outdoor unit is above: 15 meters.
• Maximum height difference between indoor units when the outdoor unit is above: 7.5 meters.
• Maximum height difference between outdoor and indoor units when the outdoor unit is below: 7.5 meters.
• Maximum height difference between indoor units when the outdoor unit is below: 15 meters.
• Total length covered by the factory refrigerant charge: 30 meters of liquid piping.
• Additional refrigerant charge: 20 grams per additional meter when the total length exceeds 30 meters, applying the calculation and rounding procedure indicated by Daikin.
• Maximum permitted total refrigerant charge: 2.2 kg.

For example, an installation can be carried out with refrigerant runs of 10, 15 and 20 meters, resulting in a total length of 45 meters. This distribution complies with the maximum lengths established by the manufacturer, although the height differences and other technical conditions must also be checked.

When exceeding the 30 meters 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 meters, the calculation would be 300 grams additional, following the procedure established in the Daikin manual.

Refrigerant length refers to the one-way run of the liquid pipe between the units, without adding again the length of the gas pipe in the same circuit.

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: insulation with a minimum thickness of 10 mm.
• 3/8" gas pipes: insulation with a minimum thickness of 13 mm.
• Material: polyethylene foam suitable for refrigeration installations, with thermal resistance of at least 120 °C.
• Copper pipes: seamless copper, phosphorus deoxidized 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 an insulation thickness of at least 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 + 3.5 kW recommended for?

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

A common layout may consist of installing the two 2.0 kW FTXM20B units in small bedrooms, children's rooms or offices, while the 3.5 kW FTXM35B unit is used in a living room, dining room or larger bedroom.

As a commercial guideline, the 2.0 kW units may be suitable for rooms of approximately 12 to 20 m², while the 3.5 kW unit can be used in rooms of approximately 25 to 35 m².

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

It is also important to bear in mind that, when the three indoor units operate simultaneously, the available power 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 Daikin Perfera 3x1 set consists of two FTXM20B indoor units, one FTXM35B indoor unit 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 pipes, trunking, outdoor unit supports and fixing elements will be required.

It will also be necessary to check the correct use of the refrigerant reducers 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 connections of each indoor unit.

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