Product Identification
Bonaire Optima Series III MK2 7.2kW Split System – STH072S1AI / STH072S1AE
Indoor unit: STH072S1AI |
Outdoor unit: STH072S1AE |
System type: Reverse cycle wall-mounted split system
Product Overview
The Bonaire 7.2kW split system is a high-capacity reverse cycle air conditioner designed to provide powerful heating and cooling for larger living rooms, family areas and open-plan residential spaces. This complete system combines the STH072S1AI indoor unit with the matching STH072S1AE outdoor unit, supplying both components as one properly matched air conditioning system.
With 7.2kW rated cooling capacity and 7.1kW rated heating capacity, this model provides substantial performance for rooms requiring more output than a standard bedroom air conditioner. Reverse cycle operation allows the same system to cool the space during Melbourne’s warmer weather and provide efficient heating during colder periods.
The Bonaire Optima Series III MK2 range includes inverter technology, smart Wi-Fi control, R32 refrigerant, 3D airflow, self-cleaning functionality, dehumidification and an “I Feel” temperature-sensing function. These features combine convenient control with practical everyday comfort.
This system is also supported by Bonaire’s industry-leading seven-year parts and labour warranty for eligible installations. Current warranty terms, registration requirements, professional installation conditions and servicing obligations should be reviewed before purchase.

Why Choose the Bonaire 7.2kW Split System?
The Bonaire STH072S1AI 7.2kW split system is designed for residential spaces that require substantial cooling and heating capacity. Its higher output makes it a practical option for family rooms, larger lounge areas and suitable open-plan layouts where a smaller air conditioner may struggle to maintain the selected temperature.
Inverter technology allows the compressor to vary its output according to the room’s heating or cooling demand. When the room approaches the selected temperature, the system can reduce its output instead of continually operating at maximum capacity. This supports steadier comfort and can reduce unnecessary energy use.
The system has a cooling operating range of approximately 1.5kW to 7.7kW and a heating operating range of approximately 1.3kW to 7.5kW. This variable operation allows the air conditioner to respond to changing indoor and outdoor conditions.
Actual performance, power consumption and running costs will depend on room size, insulation, ceiling height, windows, sunlight exposure, outdoor temperature, selected settings and installation quality. A professional assessment is recommended before choosing a high-capacity system.
Key Features
Powerful Reverse Cycle Operation
The system provides 7.2kW rated cooling and 7.1kW rated heating, making it suitable for larger areas requiring year-round temperature control.
Smart Wi-Fi Control
Compatible functions can be accessed through a suitable smartphone or tablet after the system has been connected and configured correctly. Users may adjust settings, create schedules and manage operation remotely.
Inverter Technology
Inverter operation allows the system to adjust its output based on room conditions rather than operating continuously at one fixed capacity.
R32 Refrigerant
The system uses R32 refrigerant, which is commonly used in modern residential split systems. Refrigerant handling and installation must be completed by an appropriately licensed professional.
3D Airflow
The 3D airflow function assists with distributing conditioned air around a larger room, supporting more balanced comfort across the occupied area.
“I Feel” Temperature Sensing
The “I Feel” function can help the system respond to conditions around the sensing location instead of relying only on the temperature measured at the wall-mounted unit.
Dehumidification Mode
Dehumidification can help reduce excess indoor moisture during humid conditions, improving comfort without always requiring maximum cooling output.
Self-Cleaning Function
Self-cleaning technology supports the ongoing care of the indoor unit. This function does not replace regular filter cleaning, inspection or professional maintenance.
Gold Fin Coating
Gold Fin coating provides additional corrosion resistance for the outdoor heat exchanger. Correct installation positioning and routine maintenance remain essential.
DRED Enabled
Demand Response Enabling Device compatibility allows the system to support applicable demand-response programs when the necessary equipment and services are available.
Industry-Leading 7-Year Warranty
Bonaire promotes a seven-year parts and labour warranty for eligible Series 3 systems. Warranty eligibility may depend on professional installation, registration, proof of purchase, servicing requirements and compliance with the manufacturer’s current warranty terms. Customers should retain their purchase, installation and servicing documentation.
Ideal Applications
- Larger family living rooms
- Open-plan lounge and dining areas
- Large residential rooms
- Apartments and townhouses with larger shared spaces
- Rooms with higher heating or cooling requirements
- Replacement of an older, similar-capacity split system
The 7.2kW capacity does not automatically make this model suitable for every large room. Open-plan spaces can have different heat loads depending on their layout, connected areas, insulation and glazing. A professional load assessment can help prevent selecting a system that is either undersized or unnecessarily large.
