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

The VRV II-S system offers least limitations to where it may be installed. The operating temperature range for heating goes all the way down to -20 °C, while cooling can be performed with outdoor temperatures as high as 46 °C. Both these achievements are due to the employment of a high-pressure dome-type ccompressor.
