6 Simple and rapid installation
6-10 Sequential start - VRVII & VRV-WII
Up to 3 outdoor units can be connected to 1 power supply and can be turned on sequentially. This allows the number of breakers and their capacities
to remain small and simplifies wiring (for models of 10Hp or less).
6-11 Self diagnosis - VRVII & VRV-WII
Detects malfunctions in major locations of the system and displays the type of malfunction and location, which in turn allows servicing and maintenance
to be performed more efficiently.
6-12 Crosswiring check - VRVII & VRV-WII
The cross wiring check facility available on the VRVII is the first of its type in the industy to warn operatives of connection errors in interunit wiring and
piping. This function identifies and alerts system errors by means of on/off LEDs on the outdoor unit's PC boards.
6-13 Simplified wiring - VRVII & VRV-WII
• A simple 2-wire non-shielded multiplex transmission system links each outdoor unit to multiple indoor units using one 2-core wire, thus simplifying
the wiring operation.
• Furthermore, outdoor units have power connection outlets on side and front, resulting in easier installation and maintenance and saving space when
rows of units are connected together.
6-14 "Super Wiring" system - VRVII & VRV-WII
• A Super Wiring system is used to enable the shared use of wiring between indoor units, outdoor units and the centralised remote control.
• This system makes it easy for the user to retrofit the existing system with a centralised remote control, simply by connecting it to the outdoor units.
• Thanks to a non polarity wiring system, incorrect connections become impossible and installation time is reduced.
