The LG UHS150SPSET is a high static reverse cycle splittable ducted air conditioning system designed for very large homes, offices, and commercial spaces that require long duct runs, strong airflow, and easier installation in restricted roof spaces. Its splittable indoor unit design allows the system to be transported in sections and assembled on site, making it ideal for properties with difficult roof access or narrow ceiling cavities. It includes the indoor UHN150M4S unit, outdoor UU150WR2 unit, and PREMTB101 wired wall controller. With 15.2kW cooling and 18.0kW heating capacity, this model is ideal for very large open-plan homes, multi-room properties, offices, and commercial spaces around 70–110m² depending on insulation and layout. The system can modulate from approximately 6.0kW to 16.5kW in cooling mode and from 6.5kW to 19.5kW in heating mode, helping maintain stable temperatures while reducing energy use.

Key Features & Benefits

Splittable Indoor Unit Design

The indoor unit is designed in sections to simplify transport through tight roof spaces, narrow hallways, and difficult access points. This makes installation easier in homes and commercial spaces where a standard one-piece indoor unit may be difficult to position.

High Static Pressure Performance

The system supports external static pressure from approximately 49Pa to 196Pa, making it suitable for long duct runs, multiple outlets, and larger zoned ducted systems. Airflow ranges from approximately 450 litres per second up to 1,180 litres per second, helping maintain strong and even air distribution throughout the property.

Single-Phase Power Supply

This model operates on standard 220–240V single-phase power, making it suitable for larger residential properties without requiring a 3-phase electrical upgrade. Rated current is approximately 18 amps in cooling mode and 20 amps in heating mode, with a full load current of approximately 32 amps.

Energy Efficient Inverter Scroll Compressor

The system uses an inverter scroll compressor with a BLDC motor to provide smoother temperature control, quieter operation, and lower running costs than fixed-speed systems. It delivers an AEER of approximately 3.45 and an ACOP of approximately 3.85.

Strong Airflow Performance

This model is designed for very large homes and commercial spaces where strong airflow is essential. The larger duct connections and high static design help distribute conditioned air evenly across multiple rooms and long duct layouts.

Compact Indoor Unit Design

The indoor unit measures approximately 1250mm wide, 360mm high, and 820mm deep, while the outdoor unit measures approximately 950mm wide, 1380mm high, and 330mm deep. Despite its large capacity, the system remains compact enough for many residential and commercial roof spaces.

Quiet Operation

Indoor sound levels are approximately 46dBA on high fan speed, 44dBA on medium, and 42dBA on low fan speed. Outdoor sound pressure levels are approximately 54dBA in cooling mode and 55dBA in heating mode.

Long Pipe Run Capability

The system supports refrigerant pipe runs from 5 metres up to 85 metres, with a maximum height difference of 30 metres between indoor and outdoor units. This provides installers with greater flexibility for larger homes and more complex layouts.

Wide Operating Range

The unit can operate in outdoor temperatures from -15°C to 48°C in cooling mode and from -18°C to 18°C in heating mode, making it suitable for Australian climate conditions year-round.

R32 Refrigerant

The system uses modern R32 refrigerant for improved efficiency and lower environmental impact compared to older refrigerants. Refrigerant piping uses a 3/8-inch liquid line and 3/4-inch gas line.

Optional Wi-Fi Compatibility

The system is compatible with optional Wi-Fi control, allowing users to remotely manage temperature settings and operating modes through compatible LG smart control systems. It also supports zoning integration for improved comfort and energy savings.

PREMTB101 Controller Included

This system includes the LG PREMTB101 wired wall controller for easy temperature adjustment, operating mode selection, timer functions, and day-to-day system management.
