IN485HIT001R000

The Hitachi-BACnet gateway allows fully bi-directional communication between Hitachi VRF units and BACnet MS/TP networks.

The IN485HIT001R000 gateway is wired directly to the indoor unit. This allows not only the control of the main AC functions such as operating mode, fan speed, temperature setpoint…but the monitoring of errors, alarms and some internal variables.The IN485HIT001R000 can be installed and set up in a really short time. It’s only a matter of wiring the gateway to the AC unit and configure the DIP-SW accordingly. No configuration software and no power supply are required.

Features:

• BTL mark ensures full interoperability with BACnet devices
• Support only BACnet MS/TP
• Configuration from onboard DIP-switches
• Quick and easy installation (plug and set the DP-SW)
• External power not required
• Simultaneous control of the AC unit by the manufacturer’s remote controller and BACnet MS/TP
• Reduced dimensions 93 x 53 x 58 mm
• Mountable on DIN rail, wall, or even inside the indoor unit in some models of AC
• Abstraction of Air Conditioning unit properties and functionalities as fixed BACnet Objects
• Occupancy function allows energy savings. Costs related to HVAC systems in a building are one of the highest and this type of functions allow to reduce them
• Total control and monitoring of the AC unit from BACnet, including AC unit’s internal variables, running hours counter (for filter maintenance control) and error indication
