System Free Indoor Units

System free indoor units afford the widest freedom of choice in designing air conditioning systems. All indoor units are interchangeable and may be connected to any outdoor Commercial or Set Free unit. Control is centralised, via the HITACHI H-Link II communication bus. Combining different types of indoor units for an optimal air conditioning concept, this is the freedom afforded by System Free.
