Control Systems
41
Up to 64 groups of indoor units (128 units) can be centrally controlled.
Optional controllers for centralised control can be combined freely, and
system can be designed in accordance with building scale and purpose.
System integration with various air-conditioning peripheral
equipment, such as a Heat Reclaim Ventilator, is easy.
Wiring can be run up to a total length of 2 km, and adapts easily to
large-scale system expansion.
