LG LT-B3020HL is a cassette-type ceiling air conditioner designed for both cooling and heating purposes. It features an anti-biofilter for cleaner air, a compact design for easy installation in tight spaces, and quiet operation for a more comfortable environment. The dual timer allows for programming the air conditioner to turn on or off automatically, while the soft dry operation mode dehumidifies the air without overcooling. Additionally, the unit automatically restarts after a power failure for added convenience.
