✔️ BLDC Twin Rotary Compressor with pressure sensor: The outdoor Unit it uses an eccentric double rotor motor that balances internal centrifugal forces. By including an electronic sensor that continuously measures the pressure and the temperature of the R32 refrigerant gas, the algorithm optimizes the exact turns regime, reaching the desired temperature faster and decreasing consumption.

✔️ Blindaje Ocean Black End of High Durability: The heat exchanger of the outdoor Unit it is covered with a double layer of modified epoxy resin and a protective hydrophilic coating. This barrier neutralizes the accumulation of water droplets and avoids galvanic corrosion caused by salinity in coastal zones or urban pollution, drastically prolonging system life.

✔️ Smart home friendly ecosystem LG Thinq with AI: Every indoor Unit includes factory pre-installed a Wi-Fi receptor module within its own structure. By linking with the ThinQ application, it allows you to control the three areas independently, configure complex weekly timers, monitor instant energy use and activate artificial intelligence functions to adapt the air conditioning to your life habits.

✔️ Silent operation of 19 dB Sleep: By inclining the slats of the cross-flow fan and the use of a sinful continuous power motor, the split reduces the operating turbulence of air passage. When activating the night or low speed mode, it emits a slight imperceptible murmur of 19 decibels that ensures an unbeatable rest environment.

✔️ Active energy control and dual filter: The systems of LG they allow to limit the maximum consumption power of the compressor voluntarily through the remote control, optimizing spending. In addition indoor Unit it has a double action filtering system responsible for retaining floating fine dust particles.

How does Asymmetric Management work for stays with units of 2.5 kW and 3.5 kW?

Independence in air conditioning is total and is electronically coordinated by the expansion valves of the outdoor Unit. Each of the Comfort mural units has its own remote control and its own thermal reading probes. You can program the 3.5 kW unit in the main room in cold mode during the day while the 2,5 kW units of the bedrooms remain completely off or at a smooth setpoint temperature, adapting the outer compressor exactly to the defendant proportional expenditure.

Is it necessary to purchase any optional accessory for Wi-Fi control?

No, the mural units of the Confort Series incorporate the pre-installed wireless receptor module within the equipment's own chassis. It is not necessary to buy external domotic gateways or perform additional wiring. You only need to have an Internet wireless internet connection and download the official application for free LG Thinq on your Smartphone or Tablet.

What are the refrigeration distances and installation limitations of this set?

According to the official tab of LG, the outdoor Unit MU3R21 supports a maximum total length of pipes up to 50 meters by adding the three branches, with a maximum limit by individual branch of up to 25 meters. The maximum vertical rate allowed between the outdoor Unit and the indoor Unit further away is 15 meters, while the maximum rate between the internal units installed in the house is up to 7.5 meters, which gives a great geometric versatility of assembly.
