✔️ Intelligent substitution without works: The interior units of the series LG Infinity have been specifically designed to facilitate the renewal of old equipment. Its internal architecture allows you to connect to the pre-existing copper pipelines in the housing in a clean and efficient way, minimizing complications in installation and despecurs.

✔️ Intelligent ecosystem LG Thinq with integrated Wi-Fi: Every indoor Unit includes factory pre-installed a wireless receiver module. By linking with the ThinQ application on your smartphone, it allows you to control the three zones in a totally independent way, configure complex weekly timers, monitor instant energy use and activate automated functions for artificial intelligence.

✔️ BLDC compressor Twin Rotary High efficiency: The outdoor Unit it uses an eccentric double rotor motor that balances the mechanical forces of internal rotation. By including an electronic sensor that continuously measures the pressure and temperature of the R32 refrigerant gas, the algorithm of LG it optimizes the exact returns, reducing the electrical consumption to the indispensable minimum.

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

✔️ Silent operation of 19 dB Sleep: By optimizing the lamas of the cross-flow fan and the use of a brushless direct current motor, the split significantly reduces the operating turbulence of air passage. When activating night mode, it emits a slight murmur of 19 decibels that ensures an unbeatable rest environment.

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

Independence in the air conditioning of the three stays is total and is electronically coordinated by the expansion valves of the outdoor Unit. Each of the Units of the Infinity series 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 soft sticker temperature, adapting the exterior compressor exactly to instant proportional expense Respondent to avoid more consumption.

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

No, the mural units of the series LG Infinity incorporate the factory pre-installed wireless receiver module within the chassis of the equipment. 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.
