Mitsubishi Electric offers a large range of controls to meet every need. Local controllers are available that can control 1 to 16 indoor units. Central controls and BMS systems are available that can control  up top 1000 indoor units. The unique Network control system makes it possible to link individual  systems to each other, these systems can then also be controlled from a central location. This allows easy upgradeable control for small to large buildings and gradual  expansion of  City Multi HVAC system.
