Intesis IN485MIT001A000 (Mitsubishi Electric Ecodan gateway, BACnet MS/TP) BACnet points list
Updated 4 November 2026
Intesis interface for one Mitsubishi Electric Ecodan air-to-water system, plugged into CN105 and speaking BACnet MS/TP (default) or Modbus RTU. It exposes 115 objects: system and zone on/off, heat/cool mode, zone 1 and zone 2 setpoints with limits and water temperatures, DHW control (eco, boost, legionella), holiday mode, compressor, pump and backup-heater status, flow and energy counters.
This page lists 115 BACnet objects for the Intesis IN485MIT001A000 (Mitsubishi Electric Ecodan gateway, BACnet MS/TP) — 27 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 IN485MIT001A000 (Mitsubishi Electric Ecodan gateway, BACnet MS/TP)
Plug the gateway into CN105 on the Ecodan board, leave SW1 position 5 OFF for BACnet MS/TP and set the MAC address on SW2. Turn the system on with OnOff_command, set heat or cool with ZonesMode_command (both zones follow), and write zone and DHW setpoints to their _command objects.
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.
| Object | Name | Why | Access |
|---|---|---|---|
| BO 4 | OnOff_command | Turn the Ecodan system on/off | Command |
| MO 0 | ZonesMode_command | Heat or cool for both zones | Command |
| BO 15 | DHWOnOff_command | Domestic hot water on/off | Command |
| AO 3 | Zone1TempSetpoint_command | Zone 1 setpoint from the BMS | Command |
| AO 24 | DHWTempSetpoint_command | DHW tank setpoint | Command |
| BI 5 | OnOff_status | Confirms the system is on | Read |
| AI 74 | TempOutletWaterRef_status | Flow water temperature | Read |
| BI 1 | ErrorFlag_status | Unit alarm | Read |
| AI 2 | ErrorCode_status | Which fault is active | Read |
Enable & remote start
BO 3 RemoteControlLock_command = 1 lets only the BMS control the unit; remote-controller commands are then ignored.
Sensors & values from the BMS
Write a BMS room temperature to AO 8 Zone1TempBACnetRoomThermAmbientRef_command (AO 22 for zone 2). Once a valid value is written, the gateway's Virtual Temperature function uses it to offset the setpoint.
Network setup
- SW1 P5: OFF = BACnet MS/TP (default), ON = Modbus RTU; SW1 P6-P8 baud rate, autobaud by default.
- MS/TP MAC address on SW2 P1-P7; SW2 P8 selects °C (default) or °F.
- Default device instance 246000; in automatic mode it is 246000 + the MAC address. Writing Object_Identifier switches to manual addressing until a factory reset.
- DIP switch changes take effect after a reboot.
Watch out for
- Write the _command object and read the matching _status object; they have different object types and instance numbers.
- Custom setpoint limits cannot go past the unit's own limits (the Unit...Limit objects); the Applied...Limit objects show the range in force.
- Write 0 to CompressorOperatingTime_command or CirculationPumpOperatingTime_command to reset that run-hour counter.

Integration notes
- The manual's object table has no read/write column. Access is inferred: AO/BO/MO command objects as commandable, inputs as read-only.
- Footnote numbers printed after some object names in the table (for example ErrorCode_status2) are not part of the name and were removed.
- ErrorCode_status (AI 2) shows the code as a Mitsubishi centralized controller shows it; ErrorSubCode_status (AI 3) shows it as the Ecodan unit shows it.
- Run-hour and flow counters roll back to 0 at 720896; energy counters at 2147483647 kWh.
- Temperatures follow the °C/°F setting on DIP switch SW2 position 8.
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 IN485MIT001A000 (Mitsubishi Electric Ecodan gateway, BACnet MS/TP) and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.
Questions about the Intesis IN485MIT001A000 (Mitsubishi Electric Ecodan gateway, BACnet MS/TP)
How many BACnet points does the Intesis IN485MIT001A000 (Mitsubishi Electric Ecodan gateway, BACnet MS/TP) have?
This list has 115 BACnet objects: 58 analog inputs, 18 analog outputs, 27 binary inputs, 6 binary outputs, 3 multi-state inputs, 3 multi-state outputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Intesis IN485MIT001A000 (Mitsubishi Electric Ecodan gateway, BACnet MS/TP) BACnet points are writable?
27 of the 115 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 Intesis IN485MIT001A000 (Mitsubishi Electric Ecodan gateway, BACnet MS/TP) BACnet documentation?
The source is IN485MIT001A000 User Manual - Mitsubishi Electric Ecodan Air-to-Water Units to BACnet MS/TP and Modbus RTU, revision 2025-12-02 v1.0.3, published free by Intesis at https://www.hms-networks.com/docs/default-source/products/intesis/manuals-and-guides---manuals/user-manual-in485mit001a000.pdf.
What are the minimum BACnet points to integrate the Intesis IN485MIT001A000 (Mitsubishi Electric Ecodan gateway, BACnet MS/TP)?
Start with BO 4 OnOff_command (Turn the Ecodan system on/off); MO 0 ZonesMode_command (Heat or cool for both zones); BO 15 DHWOnOff_command (Domestic hot water on/off); AO 3 Zone1TempSetpoint_command (Zone 1 setpoint from the BMS); AO 24 DHWTempSetpoint_command (DHW tank setpoint); BI 5 OnOff_status (Confirms the system is on); AI 74 TempOutletWaterRef_status (Flow water temperature); BI 1 ErrorFlag_status (Unit alarm); AI 2 ErrorCode_status (Which fault is active).
How do I enable BMS control of the Intesis IN485MIT001A000 (Mitsubishi Electric Ecodan gateway, BACnet MS/TP)?
BO 3 RemoteControlLock_command = 1 lets only the BMS control the unit; remote-controller commands are then ignored.
Can the BMS supply sensor values to the Intesis IN485MIT001A000 (Mitsubishi Electric Ecodan gateway, BACnet MS/TP)?
Write a BMS room temperature to AO 8 Zone1TempBACnetRoomThermAmbientRef_command (AO 22 for zone 2). Once a valid value is written, the gateway's Virtual Temperature function uses it to offset the setpoint.
How do I check these points on the real IN485MIT001A000 (Mitsubishi Electric Ecodan 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.
