–HVAC integration for Building Management Systems (BMS)
Connect Hitachi HVAC units to your BMS/BEMS* via our range of gateways to synchronise cooling/heating operation with other building equipment.


– Wide building size & protocol compatibility
Our gateways matches the most popular protocols in the market, such as BacNetTM, LonWorks®, KNX® and ModBus® to establish seamless communication between the Hitachi cooling systems and the BEMS interface.
With diverse connection capacities, our gateways can complement the existing systems of different sizes of buildings.

– Adjust comfort to suit each room’s needs
From their BEMS, facility manager can modify at any time the operation of the desired AC units. They can optimize the temperature and fan speed to ensure that each room receives the cooling/heating required. To optimize energy savings, the AC can be synchronized with other equipment to automatically power off when the room is unoccupied, reducing unnecessary cooling or heating.

– Building Management Systems are easy to install thanks to H-Link
Connect the Gateway on Hitachi H-LINK wiring. H-LINK is particularly flexible. The connection can be established at any point, so installers can opt for the fastest route. Hitachi VRF systems are directly based on H-LINK. Other Commercial AC Systems - like PRIMAIRY can be added with a H-LINK adapter[1].

– Combine with airCloud Pro for cloud-based control
Depending on your organization’s routine, facility managers can combine BEMS with airCloud Pro cloud-based management tool, to receive AC error event information on their phone 24/7.
– Additional Benefits

Certified compatibility[2]
Certified compatibility with key network protocols, plus partnerships with BMS gateway manufacturers ensures you can confidently plan integration of Hitachi HVAC equipment with BMS and BEMS systems.

Error codes
Display Hitachi AC error codes in the BMS: enabling equipment managers to diagnose faults more quickly

Scheduling[2]
Program the AC operation from within the BMS system, so buildings can be pre-cooled or pre-heated before regular opening hours

Set restrictions[2]
Restrict the temperature setpoint range from within the BMS system to prevent excessive cooling or heating temperatures
