Product Information:
- Inverter Technology: LG's heat pump systems are designed with efficient inverter technology. An electronic expansion valve and a variable speed compressor carefully regulate the refrigerant flow, reducing energy consumption and allowing for consistent, accurate temperatures.
- Built-In Wi-Fi: The KNSAE121A has built-in Wi-Fi, enabling the control of your LG air conditioner with smart enabled devices. Simply download the SmartThinQ® app on your smart device to get started.
- Gold Fin Protection: To ensure the reliability and longevity of the KUSAE121A's heat exchanger, LG employs a Gold Fin coating that prevents corrosion and improves durability.
- Quiet Design: The KNSAE121A indoor unit features a cross flow fan that restricts the pressure of air flow and lowers sound levels. Both the outdoor and indoor units enjoy reduced electrical and mechanical sound thanks to their brushless direct current fan motors.
- Self-Cleaning Coil: The KNSAE121A features a self-cleaning heat exchanger coil that automatically removes dirt and moisture. This helps to prevent unpleasant odors and to combat the formation of mold.
- Jet Temperature Control: Quickly get your zone comfortable with the Jet Heat and Jet Cool modes. With the press of a button, your system will temporarily adjust the set point and fan speed to provide rapid heating or cooling.
- Sleep Mode: With the Sleep Mode and Timer functions, you can set the indoor unit to save energy at night. Sleep Mode will incrementally adjust temperature for an hour before the Timer function automatically deactivates the unit.
- Dehumidify: LG's indoor units include a dehumidifying operation mode. In this mode, the unit's internal sensors monitor temperature and modify the set point and fan speed to remove moisture from the air.
- Improved Air Quality: The KNSAE121A uses a dual filtration system to keep your air clean. A washable anti-fungal filter protects against dust and bacteria, while a 3M Micro Protection Filter captures microscopic irritants for pristine air quality.
