This 24,000 BTU ducted central AC system delivers efficient cooling and heating with R-454B refrigerant and 18 SEER2 performance supported by inverter technology. The heat pump operates in temperatures as low as –5°F / –20°C, providing steady comfort through colder seasons.

A dual-stage inverter rotary compressor helps maintain stable indoor temperatures across bedrooms, living rooms, and multi-room layouts. With RS-485 and 24V control support, the unit integrates easily with different central AC configurations. High static pressure (200 Pa) and 7 fan speeds deliver strong, balanced airflow for multi-room or multi-floor spaces.

The system also offers optional upgrades, including a wired controller for fixed-location control and a 10kW heat kit for added heating support in extremely cold climates. These options provide more flexibility for your setup and local weather needs.

The indoor unit supports both vertical and horizontal installation to fit a variety of layouts. Note: Professional installation is required; not suitable for DIY. Electrical specs: Indoor unit max fuse 15A, outdoor unit max fuse 25A.
