• 2 Daikin ARC466A93 wireless remote controls: one for each indoor unit, allowing individual control of temperature and the main air conditioning functions.

This configuration allows two rooms to be conditioned using a single outdoor unit, reducing the space occupied on façades, balconies and terraces compared with installing two independent split systems.

Main advantages of the Daikin Perfera 2x1 air conditioner

Independent climate control for two rooms

The Daikin Perfera multisplit system allows the two 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 bedroom or office, while the 5.0 kW FTXM50B unit is intended for a living room, dining room or larger space.

Both 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 the other.

This configuration makes it possible to take advantage of the outdoor unit capacity to condition two areas of the home without giving up individual control of each room.

Smart WiFi control via Daikin Onecta

The Daikin Perfera FTXM20B and FTXM50B indoor units feature WiFi connectivity so you can manage the air conditioning from a smartphone or tablet using the Daikin Onecta app.

The app allows each indoor unit to be controlled individually from anywhere with an Internet connection, making temperature management easier even when you are not at home.

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.
• Management of energy functions available from the app.
• Control of the main functions via compatible voice assistants such as Amazon Alexa and Google Assistant.

WiFi control makes it possible to adapt operation 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 indoor 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.

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

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

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 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 reduce electricity consumption.

This technology improves comfort and optimises air conditioner operation without the need to constantly adjust the temperature from the remote control.

Even air distribution with Comfort+ and 3D airflow

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

In addition, the 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 within the room and provide greater thermal comfort during operation.

Quiet operation for bedrooms and rest areas

The Daikin Perfera range is designed to offer quiet operation. However, sound levels depend on the size of each indoor unit and the selected speed.

• Daikin FTXM20B 2.0 kW: minimum sound pressure of 19 dB(A) in cooling and 20 dB(A) in heating.
• Daikin FTXM50B 5.0 kW: minimum sound pressure of 27 dB(A) in cooling and 31 dB(A) in heating.

The FTXM20B is especially suitable for bedrooms and spaces where very quiet operation is desired. The FTXM50B, on the other hand, offers greater airflow and air conditioning capacity, adapting to larger rooms.

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 air to circulate in the room without activating cooling or heating.
• Weekly programming: makes it easy to set customised schedules.
• Auto restart: restores previous settings after a power interruption.
• Temperature limit: allows regulation limits to be set to avoid excessively high or low temperatures.
• Energy saving in standby: helps reduce consumption when the system remains in standby mode, depending on the installation configuration.

Cooling and heating capacity of the Daikin Perfera 2x1 set

The system combines a 2.0 kW class indoor unit and a 5.0 kW class indoor unit, whose sum of individual capacities is 7.0 kW. However, the combined nominal cooling capacity when both units operate simultaneously is 5.0 kW, determined by the performance of the Daikin 2MXM50A8 outdoor unit.

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

• Maximum cooling capacity: 5.5 kW.
• Minimum cooling power input: 0.33 kW.
• Nominal cooling power input: 1.22 kW.
• Maximum reference cooling power input: 1.44 kW.
• Calculated nominal EER: approximately 4.10.

When both indoor units operate simultaneously under nominal conditions, the cooling capacity split is:

• FTXM20B 2.0 kW unit: 1.43 kW.
• FTXM50B 5.0 kW unit: 3.57 kW.

When only one indoor unit is operating, the available capacity can adapt to the demand of that room within the unit's limits. The FTXM50B has a capacity class of 5.0 kW, but when both units operate at the same time its capacity is distributed according to the outdoor unit performance.

Heating capacity

The reversible heat pump allows the system to be used during the colder months, with a combined nominal heating capacity of 5.6 kW.

• Minimum heating capacity: 1.2 kW.
• Nominal heating capacity: 5.6 kW, approximately 19,110 BTU/h.
• Maximum heating capacity: 6.2 kW.
• Minimum heating power input: 0.25 kW.
• Nominal heating power input: 1.35 kW.
• Maximum reference heating power input: 1.50 kW.
• Calculated nominal COP: approximately 4.15.

The nominal heating capacity split when both indoor units operate simultaneously is:

• FTXM20B 2.0 kW unit: 1.60 kW.
• FTXM50B 5.0 kW unit: 4.00 kW.

These values come from Daikin's official tables for the 20 + 50 class combination with the 2MXM50A8 outdoor unit. Capacities and consumption correspond to standard test conditions and may vary depending on outdoor temperature, thermal demand and installation characteristics.

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

The Daikin 2MXM-A8 outdoor range achieves energy ratings of up to A+++ in cooling and A++ in heating, depending on the indoor unit combinations evaluated by the manufacturer.

Its main energy features include:

• Maximum reference energy class of the range in cooling: A+++.
• Maximum reference energy class of the range in heating: A++.
• Reference nominal cooling capacity of the 20 + 50 combination: 5.0 kW.
• Reference nominal heating capacity of the combination: 5.6 kW.
• Reference nominal cooling power input: 1.22 kW.
• Reference nominal heating power input: 1.35 kW.
• Technology: Inverter with Swing compressor.
• Refrigerant: R-32.
• Individual control: allows you to use only the room that needs air conditioning.
• Econo mode: helps limit maximum electricity consumption.

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

Important: the A+++ and A++ ratings correspond to the maximum reference values published for the outdoor range, not to a specific energy label for the FTXM20B + FTXM50B + 2MXM50A8 combination. The final SEER, SCOP and energy class values must be confirmed using the official documentation corresponding to these exact references.

Refrigerant connections of the Daikin Perfera 2x1

The Daikin Perfera 2x1 multisplit air conditioner has two independent refrigerant circuits to connect the FTXM20B and FTXM50B indoor units to the 2MXM50A8 outdoor unit.

Connection diameters of the indoor units

• Daikin FTXM20B 2.0 kW unit: 1/4" (6.4 mm) liquid connection and 3/8" (9.5 mm) gas connection.
• Daikin FTXM50B 5.0 kW unit: 1/4" (6.4 mm) liquid connection and 1/2" (12.7 mm) gas connection.

Connection diameters of the outdoor unit

The Daikin 2MXM50A8 outdoor unit has two refrigerant ports with the following diameters:

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

For this combination, the refrigerant connection distribution indicated by the capacity classes and the manufacturer's diameters is:

• Port A: FTXM20B 2.0 kW indoor unit, with 3/8" gas piping and 1/4" liquid piping.
• Port B: FTXM50B 5.0 kW indoor unit, with 1/2" gas piping and 1/4" liquid piping.

Installation advantage: the refrigerant connections of these two indoor units match the diameters of the respective ports on the 2MXM50A8 outdoor unit. Therefore, no refrigerant reducers are required in this arrangement.

The installer must respect the correspondence between the refrigerant circuits and the room wiring, following Daikin's connection diagram.

Maximum pipe lengths and permitted height differences

To ensure correct operation of the Daikin Perfera 2x1 system, the installation must respect the maximum refrigerant pipe lengths and height differences established by Daikin.

• Maximum pipe length per indoor unit: 20 metres.
• Maximum total refrigerant pipe length: 30 metres, adding both 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: 20 metres of liquid piping.
• Additional refrigerant charge: 20 grams per additional metre when the total run exceeds 20 metres, applying Daikin's specified calculation and rounding procedure.

For example, an installation can be designed with a 10-metre refrigerant run to the FTXM20B unit and another 15-metre run to the FTXM50B unit, resulting in a total length of 25 metres. This arrangement respects the maximum length limits, although the height differences and other technical conditions must also be checked.

In this example, the theoretical additional refrigerant calculation would be 100 grams of R-32, following the manufacturer's instructions.

Refrigerant length is calculated by taking the one-way run of the liquid pipe 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 from forming.

• 1/4" liquid pipes: minimum insulation thickness of 10 mm.
• 3/8" gas pipe of the FTXM20B: minimum insulation thickness of 13 mm.
• 1/2" gas pipe of the FTXM50B: 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" 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 specifies a minimum insulation thickness of 20 mm to prevent surface condensation.

The installer must also check the correct condensate drainage, electrical supply and the necessary clearances around the outdoor unit.
