Dramatic Reduction of Wiring Saves Time and Labor When Installing

With the existing VRV H Series, the transmission wiring between indoor and outdoor units and central
transmission line for when using a central remote controller are run separately. The VRV PLUS Series
takes maximum advantage of our exclusively developed DIII-NET which boasts high speed and high
performance to realize the use of an super wiring system which enables transmission signals of
transmission wiring between indoor and outdoor units (on/off, cool/heat mode, preset temperature, current
indoor/outdoor temperature, malfunction signals, etc.) to be used with transmission signals on the central
transmission line. The dramatic reduction in wiring realized by doing so reduces wiring cost, facilitates
connection, and reduces the possibility of incorrect connection in the field. Even if wires are incorrectly
connected, the system is equipped with a wiring mistake check function which improves reliability of the
system as a whole. Because the VRV PLUS Series uses an improved wiring system, you can connect
optional controllers for centralized control anywhere on the transmission wiring between indoor and
outdoor units. The system also provides flexibility for situations that may arise when designing or installing.
The double-core, no-polarity wiring doesn't require special care when connecting, so you run wiring without
having to worry about polarity.
