The LG UHS100SPLSET is a high static reverse cycle splittable ducted air conditioning system designed for larger homes, offices, and commercial spaces that require long duct runs, strong airflow, and easier installation in tight roof spaces. Its splittable indoor unit design allows the unit to be transported in sections and assembled on site, making it ideal for restricted roof access and narrow ceiling spaces. It includes the indoor UHN100M2S unit, outdoor UU100WR3L unit, and PREMTB101 wired wall controller. With 10.5kW cooling and 13.0kW heating capacity, this model is ideal for large open-plan homes, offices, and multi-room properties around 45–75m² depending on insulation and layout. The system can modulate from 4.2kW to 13.0kW in cooling mode and from 5.2kW to 13.9kW 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 39Pa to 137Pa, making it suitable for longer duct runs, multiple outlets, and larger zoned ducted systems. Airflow ranges from approximately 377 litres per second up to 893 litres per second, helping maintain strong and even air distribution throughout the property.

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. Rated current is approximately 4.3 amps in cooling mode and 4.9 amps in heating mode, with a full load current of approximately 14 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 3.75 and an ACOP of approximately 4.0.

Compact Indoor Unit Design

The indoor unit measures approximately 1250mm wide, 270mm 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 45dBA on high fan speed, 43dBA on medium, and 41dBA on low fan speed. Outdoor sound pressure levels are approximately 50dBA in both cooling and heating modes.

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. It uses a 3/8-inch liquid line and 5/8-inch gas line for refrigerant piping.

Optional Wi-Fi Compatibility

The system is compatible with optional Wi-Fi control, allowing users to remotely control temperature settings and operating modes through compatible LG smart control systems.

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.

Ideal Applications

• Large homes
• Open-plan living areas
• Multi-room homes
• Offices
• Commercial spaces
• Homes with long duct runs
• Zoned ducted systems
• Properties with difficult roof access
