Product Usage Instructions
Installation:
Ensure the gateway is mounted inside an enclosure. Take precautions to prevent electrostatic discharge when working outside the enclosure. Follow anti-static precautions before making any adjustments or setting switches.
Configuration:
Use the onboard DIP switches for interface configuration. Refer to the installation manual for detailed instructions on setting up the gateway.
Control and Monitoring:
Utilize BACnet MS/TP for total unit control and monitoring. Access internal variables, the running hours counter, and error indication through the interface.
Power:
Intesis IN485HIT001R000 VRF Systems to BACnet MS-TP Interface
The interface is powered directly from the AC unit, eliminating the need for an external power supply.
Occupancy Function:
Activate the occupancy function to enable energy savings. This feature helps reduce costs by optimizing HVAC system operation.
Remote Control:
You can control the AC unit using both the BACnet MS/TP interface and its own remote controller simultaneously.
Item number: IN485HIT001R000
INTRODUCTION
The Hitachi-BACnet interface allows full bidirectional communication between Hitachi VRF units and BACnet MS/TP networks. The interface enables BACnet communication via polling or subscription requests (COV), making the indoor unit available through independent BACnet objects. A wired remote controller can also be connected.
Features and benefits
- BAChet MS/TP and Modbus RTU supported
The interface supports both BACnet MS/TP and Modbus RTU protocols. - VAC unit data served as fixed BACnet Objects
Air conditioning unit properties and functionalities are abstracted into fixed BACnet Objects. - Total unit control and monitoring from BACnet
Through internal variables, running hours counter (for maintenance purposes), and error indication. - No external power required
The interface is powered directly from the AC unit, so no external power supply is required. - Configuration from onboard DIP switches
The interface configuration is carried out directly through its onboard DIP switches. - An occupancy function to allow energy savings
An occupancy function that helps reduce costs, as HVAC systems are one of the main energy consumers. - AC unit control by remote and BACnet MS/TP
The AC unit can simultaneously be controlled via BACnet MS/TP and its own remote controller.

Installation Conditions |
This gateway is designed to be mounted inside an enclosure. If the unit is mounted outside an enclosure, precautions should always be taken to prevent electrostatic discharge to the unit. When working inside an enclosure (e.g., making adjustments, setting switches, etc.), typical anti-static precautions should always be followed before touching the unit. |
