Advanced technologies for high efficiency
Large propeller fan
A large propeller fan with an optimized blade angle achieves both high performance and low-noise operation.
DC inverter control
The use of a new active filter module improves efficiency.
DC fan motor
A small, multi-stage DC fan motor contributes to highly efficient, low noise operation.
Large heat exchanger
The use of a large 3-row heat exchanger substantially improves heat-exchanging performance.
Subcooling heat exchanger
The use of a dual-tube heat exchanger improves cooling performance.
DC twin-rotary compressor
High efficiency is achieved across compressor loads. Particularly high efficiency is gained in the low- to medium-load range.
Long piping length
Our advanced refrigerant control technology extends the maximum allowable length of refrigerant piping to 180 m. This provides greater flexibility in system design.
Nonstop operation during oil recovery
The air conditioner maintains uninterrupted cooling or heating operation during oil-recovery mode and keeps the room comfortable.
Easy installation
- Confirmation of correct connection
- Correct wiring connection and address settings can be confirmed by running a quick check.
- Displays the number of each connected indoor unit.
- Displays a duplicate address number assigned to an indoor unit.
