2x1 Air Conditioner with WiFi Daikin Perfera 2.5 kW + 4.2 kW

The Daikin Perfera 2x1 multisplit air conditioner with WiFi 2.5 kW + 4.2 kW is a high-efficiency climate control solution designed to keep two rooms comfortable using a single outdoor unit. This set combines Daikin Inverter technology, advanced air purification functions, and smart mobile control to provide cooling in summer and heating in winter.

The system includes two Daikin Perfera wall-mounted indoor units FTXM25B and FTXM42B, connected to a Daikin 2MXM50A8 multisplit outdoor unit. Each room can be regulated independently, allowing the temperature and fan speed to be adjusted to the needs of its occupants. Both units can operate simultaneously, always in the same cooling or heating mode.

What does the Daikin Perfera 2x1 air conditioner include?

This set is made up of the following equipment and control accessories:

• 1 Daikin Perfera FTXM25B indoor unit: wall-mounted unit with a 2.5 kW cooling class, equivalent to approximately 8,530 BTU/h. Ideal for bedrooms, offices, and small to medium-sized rooms.
• 1 Daikin Perfera FTXM42B indoor unit: wall-mounted unit with a 4.2 kW cooling class, equivalent to approximately 14,330 BTU/h. Recommended for living rooms, dining rooms, or spaces with greater climate control needs.
• 1 Daikin 2MXM50A8 outdoor unit: Inverter multisplit heat pump with R-32 refrigerant, ready to connect two indoor units, with a nominal system capacity of 5.0 kW in cooling and 5.6 kW in heating.
• 2 Daikin wireless remote controls: one for each indoor unit, reference ARC466A93, allowing individual management of temperature and climate control functions.
• WiFi control: connectivity to manage the indoor units from a smartphone or tablet via the Daikin Onecta app.

Important: the 2.5 kW and 4.2 kW figures identify the capacity classes of the indoor units. The power available when both operate simultaneously depends on the capacity of the outdoor unit and operating conditions. It should not be interpreted that the set provides 6.7 kW of simultaneous nominal cooling.

Advantages of the Daikin Perfera multisplit air conditioner

Independent climate control for two rooms

Thanks to its 2x1 multisplit configuration, this unit allows you to climate control two spaces with a single outdoor unit, optimizing available space on balconies, terraces, or façades.

The two indoor units feature independent temperature, ventilation, and scheduling control. This makes it possible to adapt comfort to each room without needing two completely separate air conditioning systems.

WiFi control with the Daikin Onecta app

The Daikin Perfera units offer smart control via WiFi and the Daikin Onecta app, available for compatible mobile devices.

From the app, you can turn the air conditioner on or off, adjust the temperature, select operating modes, and set schedules, even when you are away from home.

The range also allows control of the main functions through compatible voice assistants such as Amazon Alexa and Google Assistant.

Flash Streamer technology to improve air quality

The Perfera indoor units incorporate Daikin Flash Streamer technology, designed to help reduce certain allergens and odors present in the air.

The filtration system includes dust retention filters, a titanium apatite deodorizing filter, and a silver particle filter that helps capture certain allergens such as pollen.

Two-zone motion sensor

The smart presence sensor detects the location of people within the room to direct airflow toward another area, reducing direct drafts on occupants.

When no presence is detected, the unit can automatically activate a more energy-saving operation, helping reduce consumption without sacrificing comfort.

Uniform air distribution and quiet operation

The units feature three-dimensional air distribution, combining automatic vertical and horizontal movement to promote a homogeneous temperature throughout the room.

They also offer especially quiet operation, with minimum sound pressure levels of 19 dB(A) on the FTXM25B and 21 dB(A) on the FTXM42B during cooling in silent mode.

Refrigerant connections and maximum installation distances

The Daikin Perfera 2x1 multisplit air conditioner has two refrigerant connection circuits, one for each indoor unit. To ensure performance and safety, the installation must respect the pipe diameters, lengths, and height differences established by the manufacturer.

Connection diameters of the indoor units

• Daikin FTXM25B: liquid 1/4" (6.4 mm) and gas 3/8" (9.5 mm).
• Daikin FTXM42B: liquid 1/4" (6.4 mm) and gas 3/8" (9.5 mm).

The 2MXM50A8 outdoor unit has one 3/8" gas port and one 1/2" gas port. Therefore, to connect the FTXM42B 3/8" circuit to the outdoor 1/2" port, the corresponding reducer must be checked according to Daikin documentation. The outdoor unit includes a reducer set among its standard accessories.

Maximum lengths and permitted height differences

• Maximum pipe length per indoor unit: 20 meters.
• Maximum total pipe length: 30 meters, adding both refrigerant runs.
• 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 outdoor and indoor units when the outdoor unit is below: 7.5 meters.
• Maximum height difference between indoor units: 7.5 or 15 meters depending on the layout of the units and the conditions indicated in the manual.
• Total length covered by the factory refrigerant charge: 20 meters of liquid piping.
• Additional refrigerant charge: 20 grams per meter of piping exceeding the total 20 meters, following the manufacturer’s procedure.

For example, it is possible to design an installation with a 12-meter refrigerant run to one indoor unit and another 15-meter run to the second, since the total is 27 meters and neither run exceeds 20 meters. The height limits and other installation conditions must also be respected.

Installation of the Daikin multisplit 2x1 air conditioner

This system is suitable for homes, apartments, offices, and other spaces that need two areas to be climate controlled independently without installing two outdoor units.

Before installation, a professional must check the thermal needs of each room, the location of the units, the pipe runs, and the ventilation conditions of the outdoor unit. They must also verify the refrigerant connections, electrical supply, condensate drains, and compliance with the manufacturer’s requirements.

Important regarding supply and installation: this set includes the two indoor units, the outdoor unit, and the remote controls supplied with the units. It does not include the materials needed for installation, such as copper piping, refrigerant insulation, trunking, wiring, outdoor brackets, additional fixing elements, drains, or any other mounting accessories that may be required.

Installation must be carried out by qualified and accredited professionals authorized to work with air conditioning equipment containing fluorinated gases, in compliance with current regulations and Daikin’s official technical instructions.

With its combination of two-room climate control, WiFi control, quiet operation, and air treatment technologies, the Daikin Perfera multisplit 2x1 FTXM25B + FTXM42B + 2MXM50A8 is a high-comfort solution for those seeking efficient cooling and heating all year round.
