Mitsubishi DXK24ZRA-WF1-SET | 7.1kW Bronte Split System Air Conditioner | Built-in Wi-Fi R32 Reverse Cycle Inverter
The Mitsubishi Heavy Industries DXK24ZRA-WF1-SET is a 7.1kW reverse cycle split system air conditioner with built-in Wi-Fi, rated for single-phase 240V supply. The DXK24ZRA-WF1-SET delivers 7.1kW of cooling and 8.0kW of heating, sitting at the top of the Bronte WF1 range for medium to large rooms. It operates on R32 refrigerant pre-charged to 15 metres and pairs with the Smart M-Air application for remote operation. The unit meets AS/NZS 3823 for performance rating and supports AS4755 demand response.
Cooling a large open-plan living area or a busy commercial space often pushes an undersized unit beyond its capacity, leaving the far side of the room under-conditioned. The Bronte DXK24ZRA-WF1-SET answers this with 7.1kW cooling and 8.0kW heating and long-reach airflow up to 18 metres, so conditioned air reaches the back of wide rooms. Many installations are straight replacements for an ageing existing split that has grown noisy or inefficient, where the upgrade delivers quieter inverter operation and faster pull-down to temperature.
For the installer, built-in Wi-Fi removes the need to source and fit a separate adaptor, and the single-phase 240V supply keeps the electrical connection straightforward on a standard dedicated circuit. The factory R32 charge covers pipe runs up to 15 metres, so most domestic installations need no additional refrigerant at commissioning. The customer can then operate the unit from the Smart M-Air application, or by voice through Google Assistant or Amazon Alexa. The result is a clear capability upgrade over the previous wall controller.
Features
- 7.1kW cooling, 8.0kW heating — reverse cycle output sized for medium to large living areas, open-plan zones, and light commercial rooms.
- Built-in Wi-Fi — the DXK24ZRA-WF1-SET connects to home Wi-Fi out of the box, with no separate adaptor module to source or wire in.
- Smart M-Air app control — set temperature, mode, fan speed, and timers from a phone on iOS or Android, and view power usage remotely.
- Voice control ready — works with Google Assistant and Amazon Alexa through a compatible smart speaker, which is sold separately.
- NOVAShield PM2.5 filter — captures fine particles such as dust, pollen, and smoke, paired with the Allergen Clear filter for cleaner indoor air.
- Long-reach airflow to 18m — Jet Air fan blade design throws conditioned air across wide rooms in cooling mode.
- Inverter DC operation — varies compressor speed to hold temperature steadily and cut running noise compared with fixed-speed units.
- R32 refrigerant pre-charged to 15m — the outdoor unit ships gassed for pipe runs up to 15 metres, covering most domestic installs without a top-up.
- Single-phase 240V supply — runs on a standard single-phase dedicated circuit, with no three-phase connection required.
- LED brightness control — the indoor display can be dimmed at night to suit bedrooms and quiet spaces.
- AS4755 demand response — supports utility demand response signalling where a participating electricity network uses it.
- Professional install only — the DXK24ZRA-WF1-SET is not a DIY unit; refrigerant and electrical work must be carried out by licensed trades, and the manufacturer warranty is void without licensed installation.
Where to use
- Open-plan living and dining — the 7.1kW DXK24ZRA-WF1-SET suits large combined kitchen, lounge, and dining zones in modern homes.
- Large bedrooms and master suites — long-reach airflow and a dimmable display keep big sleeping areas comfortable and dark at night.
- Light commercial rooms — shops, salons, offices, and waiting rooms that need steady cooling and heating across the day.
- Home extensions and renovations — a single high-capacity head covers a newly opened-up space without multiple smaller units.
- Rooms needing remote control — holiday homes and rentals where owners start the DXK24ZRA-WF1-SET from the app before arrival.
- High-traffic family areas — rumpus rooms and media spaces where the unit runs long hours and quiet operation matters.
- Replacement of an ageing split — straight swaps for an older wall unit that no longer holds temperature or runs quietly.
The DXK24ZRA-WF1-SET is a single-room wall split and is not a ducted or multi-head system, so it conditions one zone rather than a whole house. It is sized for medium to large rooms, and pairing it with a small, well-sealed space can lead to short cycling. Voice control also depends on a separately purchased smart speaker, as no Google or Amazon device is included.
