The All DC Inverter Mini VRF system offers the convenience of automatic address setting for indoor units by the outdoor unit. This automated process reduces the occurrence of human errors and minimizes the need for manual configuration.

Additionally, the system features a wireless controller that allows for easy inquiry and modification of the address for each indoor unit. This wireless functionality simplifies the management and adjustment of indoor unit addresses, providing greater flexibility and convenience for users and installers alike.

Smart Electronic Control Design

The All DC Inverter Mini VRF system utilizes seamless aluminum panels for its radiation fin, providing superior cooling for the IPM compared to air cooling. With a PFC module, the system achieves a high power factor of 98%, resulting in increased efficiency.

Easy Piping Connection

The All DC Inverter Mini VRF system offers versatile installation options with four directions available for connecting pipes and wirings. This flexibility ensures compatibility with various installation requirements and configurations.

Additionally, the system includes a protective cover for the valves. This cover safeguards the valves from potential damage or external factors, promoting the longevity and reliability of the system.

Easy Installation

The All DC Inverter Mini VRF system offers the convenience of being easily transported via elevator, greatly simplifying the installation process. This feature saves time and labor, thanks to its compact size.

The Mini VRF units are designed to be more compact compared to other systems, resulting in substantial savings in installation space. This makes them particularly suitable for small-scale applications such as offices, villas, shops, and similar settings. The smaller footprint of the Mini VRF units allows for greater flexibility in installation, enabling them to be seamlessly integrated into a variety of spaces.

Easy Maintenance

The All DC Inverter Mini VRF system incorporates a forced cooling button that enables the outdoor unit to run in cooling mode regardless of the prevailing conditions. This feature simplifies the refrigerant charging process when necessary.

The system also includes a self-diagnosis function that detects malfunctions in key system components and displays detailed information about the type and location of the malfunction.
