Intesis IN485MIT001I000 (Mitsubishi Electric gateway, BACnet MS/TP) BACnet points list

Updated 11 November 2026

Short answer

One-unit Intesis interface that plugs into the CN105 socket of a Mitsubishi Electric indoor unit and exposes it on BACnet MS/TP as 31 fixed objects. Each function has a _command object to write and a _status object to read back. It includes left/right vane control, occupancy logic, a remote-controller lock and a virtual-temperature function that uses a BMS room sensor.

This page lists 31 BACnet objects for the Intesis IN485MIT001I000 (Mitsubishi Electric gateway, BACnet MS/TP) — 16 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Intesis’s own free documentation, linked below.

BMS integration notes: Intesis IN485MIT001I000 (Mitsubishi Electric gateway, BACnet MS/TP)

Integration in brief

Plug the gateway into the indoor unit's CN105 socket (CN92 on some units), set the MS/TP MAC address and baud rate on the DIP switches, then write the _command objects (on/off, mode, setpoint, fan, vanes) and read the matching _status objects. One gateway serves one indoor unit.

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; the gateway accepts commands as soon as it talks to the unit. BV 2 LockRemoteControl can lock out the wired remote.

Sensors & values from the BMS

Write the BMS room temperature to AO 1 RoomTemperature_command and the setpoint to AO 0. The gateway then runs its Virtual Temperature function and recalculates the setpoint it sends to the unit; BI 14 VirtualTempActive shows it is active and AI 17 UserSetPoint_status shows the BMS setpoint.

Integration notes

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 IN485MIT001I000 (Mitsubishi Electric gateway, BACnet MS/TP) and exports what it actually has to Excel — free.

Questions about the Intesis IN485MIT001I000 (Mitsubishi Electric gateway, BACnet MS/TP)

How many BACnet points does the Intesis IN485MIT001I000 (Mitsubishi Electric gateway, BACnet MS/TP) have?

This list has 31 BACnet objects: 7 analog inputs, 2 analog outputs, 5 analog values, 3 binary inputs, 1 binary output, 3 binary values, 5 multi-state inputs, 4 multi-state outputs, 1 multi-state value. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Intesis IN485MIT001I000 (Mitsubishi Electric gateway, BACnet MS/TP) BACnet points are writable?

16 of the 31 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.

Where is the official Intesis IN485MIT001I000 (Mitsubishi Electric gateway, BACnet MS/TP) BACnet documentation?

The source is IN485MIT001I000 Gateway - Mitsubishi Electric Residential, Mr. Slim, and City Multi Systems to BACnet MS/TP - User Manual, revision 2024-09-17 v1.2.7, published free by Intesis at https://www.hms-networks.com/docs/default-source/products/intesis/manuals-and-guides---manuals/user_manual_in485mit001i000.pdf.

What are the minimum BACnet points to integrate the Intesis IN485MIT001I000 (Mitsubishi Electric gateway, BACnet MS/TP)?

Start with BO 0 OnOff_command (Start/stop the indoor unit); MO 0 Mode_command (Heat/cool/fan/dry/auto selection); AO 0 SetPoint_command (Temperature setpoint from the BMS); MO 1 FanSpeed_command (Fan speed selection); BI 0 OnOff_status (Confirm the unit is running); AI 0 SetPoint_status (Setpoint the unit is really using); AI 1 RoomTemperature_status (Room/return temperature for trending); BI 1 ErrorActive (Unit alarm); AI 2 ErrorCode (Which fault is active).

How do I enable BMS control of the Intesis IN485MIT001I000 (Mitsubishi Electric gateway, BACnet MS/TP)?

No enable point is documented; the gateway accepts commands as soon as it talks to the unit. BV 2 LockRemoteControl can lock out the wired remote.

Can the BMS supply sensor values to the Intesis IN485MIT001I000 (Mitsubishi Electric gateway, BACnet MS/TP)?

Write the BMS room temperature to AO 1 RoomTemperature_command and the setpoint to AO 0. The gateway then runs its Virtual Temperature function and recalculates the setpoint it sends to the unit; BI 14 VirtualTempActive shows it is active and AI 17 UserSetPoint_status shows the BMS setpoint.

How do I check these points on the real IN485MIT001I000 (Mitsubishi Electric gateway, BACnet MS/TP)?

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.
