3.4 Gateways for building management systems (BMS)

3.4.1 HC-A(8/64)MB

HC-A8MB and HC-A64MB are the new interfaces which allow an easy integration of HITACHI Air Conditioning installations
to a MODBUS BMS by providing full management control of Air Conditioning installation to the BMS controllers.
• HC-A8MB and HC-A64MB include new parameters compared with current HC-A32MB:
- Gas pipe temperature reading
- Liquid pipe temperature reading
- Compressor stop cause
- Indoor unit expansion valve opening
- Ambient temperature
- Remote control switch temperature
Remote sensor temperature
-
• Two different available gateways for small and medium installations (nº. of indoor units):
- HC-A8MB: max. 8 indoor units
- HC-A64MB: max 64 indoor units (max. indoor units quantity increased from 32 units in previous version)
• Only 1 HC-A(8/64)MB can be connected to an H-LINK system.
• Many BMS Systems have gateways to MODBUS system. Therefore, HC-A(8/64)MB can be used to connect to differ-
ent BMS.
• Easy installation: HC-A(8/64)MB is provided with a DIN rail 35 mm structure for a faster assembly.
• Connectable ports:
- RS485 Modbus
- Modbus/TCP (Ethernet)
