Hisense VRF BACnet Server (HS-AC-BAC, by Intesis) BACnet points list
Updated 6 November 2026
Intesis-made BACnet server for Hisense VRF, published by Hisense Italy. It connects to the H-Link bus at the outdoor unit and serves BACnet IP and BACnet MS/TP: gateway-wide commands, an outdoor-unit block at (OU address x 25) + 1000 and one indoor-unit block per MAPS index at (index x 100) with on/off, mode, setpoint, fan, vane, air and coil temperatures, error code, filter, remote-controller permissions and dehumidification.
This page lists 51 BACnet objects for the Hisense VRF BACnet Server (HS-AC-BAC, by Intesis) — 16 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Hisense’s own free documentation, linked below.

BMS integration notes: Hisense VRF BACnet Server (HS-AC-BAC, by Intesis)
Wire the H-Link (TB2) terminals of the outdoor unit to Port A (A3/A4, no polarity), configure the units in Intesis MAPS, send the project, then map each indoor unit's _C commands and _S status objects from its (index x 100) block.
Minimum points to map
The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.

Enable & remote start
No enable point is documented. Remote-controller permissions can be removed per unit with the Allow ... from RC_C objects (BO 102-105).
Network setup
- Default device instance 246; change it in Intesis MAPS.
- BACnet IP: default IP 192.168.100.246, DHCP enabled by default. BACnet MS/TP uses Port B.
- Indoor unit index (xxx) is the unit's index in MAPS, not its H-Link address.
Watch out for
- On/Off, Mode, FanSpeed, Vane and Setpoint at instances 0-2 act on all units at once.

Integration notes
- Indoor unit instance = (xxx x 100) + offset, xxx = unit index in Intesis MAPS; index 1 shown (100-111).
- Outdoor unit instance = (xx x 25) + 1000 + offset, xx = outdoor address 1-64; address 1 shown (1025-1031).
- Made by Intesis (HMS); the object table is the same as the Intesis Hitachi VRF BACnet server INBACHIT016O000/064O000 (listed separately), as Hisense VRF uses the same H-Link bus.
- The member table has no read/write column; access is inferred (outputs commandable, inputs read-only).
- Communication Status states are printed as 0-Not Exit, 1-Exist.
Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the Hisense VRF BACnet Server (HS-AC-BAC, by Intesis) and exports what it actually has to Excel — free.

Questions about the Hisense VRF BACnet Server (HS-AC-BAC, by Intesis)
How many BACnet points does the Hisense VRF BACnet Server (HS-AC-BAC, by Intesis) have?
This list has 51 BACnet objects: 19 analog inputs, 2 analog outputs, 10 binary inputs, 7 binary outputs, 6 multi-state inputs, 7 multi-state outputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Hisense VRF BACnet Server (HS-AC-BAC, by Intesis) BACnet points are writable?
16 of the 51 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done. The source has no read/write column, so this is inferred from object type.
Where is the official Hisense VRF BACnet Server (HS-AC-BAC, by Intesis) BACnet documentation?
The source is Intesis BACnet Server - Hisense VRF User's Manual (HS-AC-BAC), revision 04/2018 r1.0, published free by Hisense at https://www.hisense.it/wp-content/uploads/2022/08/UM_bacnet-intesis_201804.pdf.
What are the minimum BACnet points to integrate the Hisense VRF BACnet Server (HS-AC-BAC, by Intesis)?
Start with BO 100 OxxUxxOn/Off_C (Start/stop indoor unit); MO 100 OxxUxxMode_C (Mode command); AO 100 OxxUxxSetpoint_C (Setpoint command); MO 101 OxxUxxFanSpeed_C (Fan speed command (1 = auto)); BI 100 OxxUxxOn/Off_S (Run status); AI 100 OxxUxxSetpoint_S (Setpoint in use); AI 102 OxxUxxInlet Temp. (Return air temperature); BI 102 OxxUxxCommunication Status (Unit present on H-Link); AI 106 OxxUxxUnit Error code (Fault code).
How do I enable BMS control of the Hisense VRF BACnet Server (HS-AC-BAC, by Intesis)?
No enable point is documented. Remote-controller permissions can be removed per unit with the Allow ... from RC_C objects (BO 102-105).
How do I check these points on the real Hisense VRF BACnet Server (HS-AC-BAC, by Intesis)?
Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
