Easy wiring

A new type of printed circuit board has been adopted that is easy to see and wire during installation.

Automatic test operation

Simply press the test operation button and the unit performs an automatic system check, including wiring, shutoff valves, sensors, and refrigerant volume. The results are returned automatically after the check finishes.

Simple wiring and piping connection

Unique piping and wiring systems make it possible to install a VRV III-S system quickly and easily.

Super wiring system

A super wiring system is used to enable shared use of the wiring between indoor and outdoor units and the central control wiring, with a relatively simple wiring operation. The DIII-NET communication system is employed to enable the use of advanced control systems.

REFNET piping system

Daikin's advanced REFNET piping system makes installation easy. Only two main refrigerant lines are required in any one system. REFNET greatly reduces the imbalances in refrigerant flow between units, while using small-diameter piping.
