LG introduces radio-frequency remote controller
New from LG for end-user benefit is a radio-frequency remote controller and receiver kit. This allows ducted indoor air-conditioning units to be controlled through any type of ceiling — wirelessly and without the need for a receiver to be fitted inside the room. Each controller has an adjustable frequency range from 432.92 to 434.92 MHz, so units can be controlled separately or multiple units can be set to work from one controller. Transmission distance is up to 20 m, and the unit may be operated from anywhere within this range regardless of obstacles such as walls or floors.
