Daikin Perfera 2x1 Air Conditioner with WiFi 2.5 kW 9000 BTU

The Daikin Perfera 2x1 multisplit air conditioner with WiFi, 2.5 kW + 2.5 kW offers an efficient climate control solution for cooling and heating two rooms using a single outdoor unit. This set combines two Daikin Perfera FTXM25B indoor units of 2.5 kW, commercially equivalent to 9000 BTU/h each, with a Daikin 2MXM40A9 outdoor unit with a nominal cooling capacity of 4.0 kW.

Thanks to Inverter technology, the heat pump with R-32 refrigerant and WiFi connectivity, it allows you to enjoy a comfortable temperature all year round, adapting operation to the needs of each room. The indoor units incorporate advanced air purification technologies, intelligent airflow distribution and quiet operation, distinctive features of the Daikin Perfera range.

The system allows the temperature and fan speed of each indoor unit to be adjusted independently, although both must operate in the same general cooling or heating mode.

Composition of the Daikin Perfera 2x1 air conditioner

This multisplit set is made up of the following units:

• 2 Daikin Perfera FTXM25B indoor units: wall-mounted 2.5 kW cooling class units each, approximately 9000 BTU/h, with WiFi control via Daikin Onecta, Flash Streamer technology and quiet operation.
• 1 Daikin 2MXM40A9 outdoor unit: Inverter multisplit unit with 4.0 kW nominal cooling capacity and 4.2 kW nominal heating capacity, with two independent refrigerant connections and R-32 refrigerant.
• 2 Daikin ARC466A93 wireless remote controls: one for each indoor unit to control their functions individually.

Installation with a single outdoor unit helps reduce the space occupied on facades, terraces and balconies, making it especially suitable for homes, apartments, bedrooms, offices and small workplaces.

Main advantages of the Daikin Perfera air conditioner

Smart WiFi control via Daikin Onecta

The Perfera FTXM25B indoor units feature WiFi connectivity so you can manage climate control from a smartphone or tablet using the Daikin Onecta app.

The app lets you turn the units on and off, change the temperature, select the operating mode, adjust ventilation and set schedules from anywhere with an Internet connection.

It is also possible to control the main functions using compatible voice assistants such as Amazon Alexa and Google Assistant.

Flash Streamer technology and air purification

The Daikin Perfera range incorporates Flash Streamer technology, designed to help reduce certain allergens and odours present in the air.

This technology is combined with several filtration elements:

• Silver allergen filter: helps capture allergens such as pollen and dust mites.
• Titanium apatite deodorising filter: helps reduce unpleasant odours.
• Dust filter: traps dust particles present in the air circulating through the unit.

Intelligent two-zone motion sensor

The two-zone presence sensor detects the position of people in the room and directs the airflow to another area, avoiding direct drafts on occupants.

If no presence is detected for a certain period, the unit can automatically activate energy-saving operation.

Even air distribution with Comfort+

The Daikin Comfort+ system improves temperature distribution through its double flaps, promoting homogeneous air circulation throughout the room.

In addition, the 3D automatic movement combines vertical and horizontal swing to distribute cold or warm air more evenly and improve comfort.

Quiet operation for bedrooms

Each Daikin FTXM25B indoor unit can operate with a minimum sound pressure of just 19 dB(A) in quiet cooling mode, a feature especially useful for bedrooms, children's rooms and rest areas.

It also includes weekly scheduling, night mode, Powerful mode for quickly reaching the desired temperature and Econo mode to limit electricity consumption.

Cooling and heating capacity of the set

Although each indoor unit belongs to the 2.5 kW class, the set uses an outdoor unit with a nominal cooling capacity of 4.0 kW. The available capacity is distributed between both indoor units depending on which ones are operating and the thermal demand.

According to Daikin capacity tables for the 25 + 25 combination with the 2MXM40A9 outdoor unit, the nominal reference values are:

• Total nominal cooling capacity: 4.0 kW, approximately 13,650 BTU/h.
• Minimum and maximum cooling capacity: 1.5 to 4.4 kW.
• Total nominal heating capacity: 4.2 kW, approximately 14,330 BTU/h.
• Minimum and maximum heating capacity: 1.3 to 4.7 kW.
• Nominal cooling capacity distributed between the indoor units: 2.0 + 2.0 kW when operating simultaneously under nominal conditions.
• Nominal heating capacity distributed: 2.1 + 2.1 kW.
• Nominal electrical consumption in cooling: 0.96 kW.
• Nominal electrical consumption in heating: 0.96 kW.

These values represent combined operation under nominal conditions. The capacity available in each room may vary depending on demand and environmental conditions.

Energy efficiency and consumption of the Daikin Perfera 2x1

The system features Inverter technology, which regulates compressor speed according to climate control needs to avoid unnecessary starts and stops, optimising electricity consumption.

The Daikin 2MXM40A9 multisplit range achieves energy efficiency class A+++ in cooling and A++ in heating, depending on the combination of indoor units installed.

As a reference, the Daikin 2026 catalogue publishes the following values for the 2MXM40A9 outdoor unit:

• Energy class in cooling: up to A+++.
• Energy class in heating: up to A++.
• Reference SEER: 8.53.
• Reference SCOP: 4.64 for average climate.
• Refrigerant: R-32.

SEER and SCOP indicators allow you to compare the seasonal efficiency of the equipment. The higher the value, the lower the electrical consumption required to provide a given amount of thermal energy under the corresponding test conditions.

Note: the energy classification and seasonal values may vary depending on the exact combination of indoor units. The above data correspond to catalogue references for the range and should be checked against the specific energy label for the FTXM25B + FTXM25B + 2MXM40A9 set.

Refrigerant connections and maximum pipe lengths

The Daikin Perfera 2x1 air conditioner has two independent refrigerant circuits that connect each indoor unit to the 2MXM40A9 outdoor unit.

Refrigerant connection diameters

• First FTXM25B indoor unit: 1/4" (6.4 mm) liquid pipe and 3/8" (9.5 mm) gas pipe.
• Second FTXM25B indoor unit: 1/4" (6.4 mm) liquid pipe and 3/8" (9.5 mm) gas pipe.
• 2MXM40A9 outdoor unit: 2 liquid connections of 1/4" and 2 gas connections of 3/8".

The connections of both indoor units are compatible with the two refrigerant ports of the outdoor unit, without the need for diameter reducers.

Maximum pipe length and permitted height differences

To ensure proper system operation, the installation must respect the maximum distances established by Daikin:

• Maximum pipe length per indoor unit: 20 metres.
• Total maximum pipe length: 30 metres, adding both refrigerant circuits.
• Minimum pipe length per indoor unit: 3 metres.
• Maximum height difference between outdoor and indoor units, with the outdoor unit above: 15 metres.
• Maximum height difference between outdoor and indoor units, with the outdoor unit below: 7.5 metres.
• Maximum height difference between indoor units: 7.5 or 15 metres, depending on the relative position of the units and the installation configuration.
• Total pipe length covered by the factory refrigerant charge: 20 metres.
• Additional refrigerant charge: 20 grams per additional metre when the total pipe length exceeds 20 metres, following Daikin manual instructions.

For example, an installation can be carried out with 10 metres of piping to the first indoor unit and 15 metres to the second, resulting in a total length of 25 metres. This distribution respects the length limits, although the height differences and other installation conditions must also be checked.

Installation and required materials
