Hitachi Air Conditioning Management System H-LINK
Hitachi Global Life Solutions
Hitachi's unique air conditioning management system H-LINK, designed with high flexibility due to the use of non-polar 2-core wiring.
H-LINK is a unique high-function transmission method developed by Hitachi, which connects outdoor units to indoor units, as well as centralized control devices to indoor or outdoor units, using a non-polarized two-core wiring method. If all outdoor and indoor units to be controlled are connected, there are fewer restrictions on wiring routes, allowing for greater design flexibility. *Loop wiring is not allowed. Flexible Wiring Configuration There are no restrictions on the order of connected units or the number of wiring branches, allowing for free wiring according to the installation locations of the units. By standardizing control functions and wiring methods, it is possible to mix building multi-air conditioners with store and office air conditioners within the same system without using adapters or dedicated connectors. Similar compatibility is also possible with packaged air conditioners for equipment (excluding certain models such as those for computers). The coexistence of store and office air conditioners, building multi-air conditioners, and room air conditioners is possible. For further details, please contact us.
