Description
Overview
The Tosot Aoraki 12,000 BTU wall-mounted ductless mini split is a complete single-zone heat pump system: indoor unit, inverter outdoor unit, remote and installation package. It is rated at 24.5 SEER2 and 9.5 HSPF2, runs on standard 115V household power and uses R32 refrigerant. Indoor unit finish: white.
Wall-mounted units are the most popular way to add heating and cooling to bedrooms, offices, additions, garages and other rooms without ductwork. This system is sized for up to about 750 sq. ft.
Key Features
- Up to 24.5 SEER2 / 9.5 HSPF2: ENERGY STAR certified and among the most efficient single-zone systems Tosot makes, with potential rebate eligibility.
- Ultra-quiet: Indoor sound as low as 19–20 dB(A); the outdoor unit drops to about 40 dB(A) in sleep mode.
- Smart humidity control: Set humidity from 30% to 80%; dry mode keeps removing moisture regardless of the weather.
- Mini-ERV ready: Works with the Tosot Mini-ERV to bring in filtered fresh air without opening windows (included on ERV packages).
- Auto Clean: A condensation, frosting, sterilization and defrost cycle cleans the indoor coil and reduces odors.
- Refrigerant leak sensor: Built-in sensor shuts the system down and raises an alarm if a leak is detected.
- Wide operating range: Cooling up to 122°F and heating down to about -20°F outdoor.
- 7 fan speeds and 45° airflow: Fine airflow control with wide air throw.
Performance & Efficiency
Rated capacity is 12,000 BTU/h cooling and 12,000 BTU/h heating, with an EER/COP of 3.81 / 3.81 W/W. The inverter compressor ramps up quickly to reach the setpoint, then slows down to hold it, which avoids the on/off cycling of single-speed equipment and cuts power use. The outdoor unit is rated to operate from -20 – 122°F.
Comfort & Control
Every indoor unit includes a wireless remote, and the TOSOT+ app adds Wi-Fi control, scheduling and voice control through Alexa or Google Home. Sleep, quiet and turbo modes, auto restart after a power outage and a dehumidification (dry) mode are built in. Aoraki adds adjustable humidity control (30%–80%), Auto Clean and a built-in refrigerant leak sensor.
