6-6 Simple and rapid installation
6-6-9 Downsizing refrigerant piping
• Reduced piping diameters
Use of high efficiency R-410A enables the VRV II to operate on a smaller refrigerant charge to be used, leading to a reduction in liquid and gas pipe
diameters.
• Reduced piping costs thanks to modular design
Smaller diameter liquid and gas piping contributes to a reduction in installation space and installation costs.
6-6-10 Sequential start
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).
6-6-11 Self diagnosis
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.
