Main advantages of the Daikin Perfera 2x1 air conditioner

Independent climate control for two rooms

The Daikin Perfera 2x1 system allows the two indoor units to be controlled independently, adjusting the temperature and airflow of each room according to the preferences of its occupants.

For example, the 2.0 kW FTXM20B unit can be installed in a bedroom or study and the 3.5 kW FTXM35B unit in a living room or a larger room.

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.

Smart WiFi control with Daikin Onecta

The Daikin Perfera FTXM20B and FTXM35B indoor units feature WiFi connectivity so you can manage the air conditioner from a smartphone or tablet using the Daikin Onecta app.

Its functions include:

• Individual on/off control of each indoor unit from anywhere with an Internet connection.
• Independent temperature adjustment for each room.
• Selection of cooling, heating, fan and dehumidification modes.
• Adjustment of fan speed and airflow distribution.
• Schedule and timer programming.
• Control of the main functions through compatible voice assistants such as Amazon Alexa and Google Assistant.

WiFi connectivity makes it possible to adapt the operation of each unit to daily routines, avoiding unnecessary air conditioning in unused rooms and helping save energy.

Flash Streamer technology to improve air quality

The Daikin Perfera indoor units incorporate Flash Streamer technology, which uses high-speed electrons to help reduce certain allergens and odours present in the 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.
• Dust filter: traps particles present in the air circulating through the indoor unit.

These features help maintain a more comfortable indoor environment and better air quality in the air-conditioned rooms.

Two-zone intelligent motion sensor

The two-zone intelligent presence sensor detects the location of people within the room and adjusts the direction of the airflow to avoid direct drafts on occupants.

When no presence is detected for a certain period, the unit can automatically activate an energy-saving mode, reducing consumption without the need to manually switch off the air conditioner.

Even air distribution with Comfort+ and 3D airflow

Daikin's Comfort+ technology uses dual flaps that optimise airflow direction to achieve a more even temperature distribution.

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

These technologies help reduce temperature differences within the room and provide greater thermal comfort.

Ultra-quiet operation of just 19 dB(A)

One of the most notable features of the Daikin Perfera range is its quiet operation. Both the FTXM20B and FTXM35B indoor units achieve a minimum sound pressure of 19 dB(A) in quiet cooling mode.

In heating mode, both units can operate with a minimum sound pressure of 20 dB(A).

These noise levels make them a suitable option for bedrooms, children's rooms, studies and other spaces where discreet climate control is desired.

Powerful, Econo and weekly scheduling functions

The indoor units include different modes to adapt their operation to the needs of each moment:

• Powerful mode: temporarily increases performance to quickly reach the desired temperature.
• Econo mode: limits the unit's maximum electrical consumption.
• Quiet mode: reduces fan speed to minimise 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 scheduling: makes it easy to set different operating times.
