The LG B70AWY-9L6 is a high static reverse cycle ducted air conditioning system designed for very large homes, offices, retail spaces, and commercial buildings that require strong airflow, long duct runs, and flexible zoning. Its high static pressure capability and large-capacity indoor unit make it ideal for demanding ducted installations across multiple rooms and larger open-plan areas. The system includes LG’s PREMTB001 backlit wired wall controller for simple day-to-day operation. With 20.0kW cooling and 22.6kW heating capacity, this model is ideal for very large homes, offices, retail spaces, and areas around 100–140m² depending on insulation and layout. It can modulate from approximately 8.0kW to 22.0kW in cooling mode and from 9.0kW to 24.9kW in heating mode, helping maintain more stable temperatures while reducing energy use.

Key Features & Benefits

High Static Pressure Performance

The system supports external static pressure from approximately 60Pa to 180Pa, making it suitable for long duct runs, multiple outlets, and larger zoned ducted systems. Airflow ranges from approximately 1,067 litres per second on low fan speed up to 1,333 litres per second on high fan speed, helping maintain strong and even air distribution throughout larger homes and commercial spaces.

3-Phase Power Supply

This model operates on 380–415V 3-phase power, making it suitable for larger homes and commercial properties with 3-phase electrical supply. The 3-phase configuration helps spread electrical load more evenly, making it ideal for larger capacity systems. Rated running current is approximately 10.9 amps in cooling mode and 10.5 amps in heating mode.

Energy Efficient Inverter Scroll Compressor

The system uses a hermetically sealed inverter scroll compressor to automatically adjust output based on room conditions. This helps provide more stable temperatures, quieter operation, and lower running costs compared to fixed-speed systems. It delivers an EER of approximately 3.09 and a COP of approximately 3.65.

Compact Indoor Unit Design

The indoor unit measures approximately 1563mm wide, 458mm high, and 791mm deep, while the outdoor unit is designed to fit larger residential and commercial installations. Despite its larger capacity, the system remains compact enough for many roof spaces and plant room applications.

Quiet Operation

Indoor sound levels are approximately 43dBA on high fan speed, 41dBA on medium, and 40dBA on low fan speed, helping maintain quieter day-to-day operation for a system of this size.

Zone Control Compatible

The system supports optional zoning for up to eight zones, allowing users to independently control airflow to different areas of the property. This can help improve comfort and reduce unnecessary energy use in unused rooms.

Wi-Fi Smart Control Compatible

The LG ThinQ® app allows remote control of the system through an optional Wi-Fi module, making it easy to adjust temperature, operating mode, and timers from a smartphone.

Backlit Controller Included

The included LG PREMTB001 wired wall controller features a backlit display, timer functions, fan speed adjustment, filter reminders, and simple operating controls for day-to-day use.

Long Pipe Run Capability

The system supports maximum pipe runs of up to 30 metres with a height difference of up to 30 metres between indoor and outdoor units, providing installers with flexibility for larger homes and commercial buildings.

5 Year Manufacturer Warranty

LG ducted systems include a 5-year manufacturer warranty when installed by a licensed technician in accordance with manufacturer guidelines.

Ideal Applications

• Very large homes
• Open-plan living areas
• Multi-room homes
• Offices
• Retail spaces
• Commercial buildings
• Homes with long duct runs
