Intesis IN770AIR***O000 for Midea commercial and VRF (700 Series Air Gateway) BACnet points list

Updated 6 November 2026

Short answer

Intesis 700 Series multi-protocol gateway set up for BACnet IP or BACnet MS/TP on a Midea commercial/VRF system. It publishes gateway-wide commands, outdoor-unit error objects at (OU x 10000) and one block per indoor unit at (unit index x 100): on/off, mode, setpoint, standard and extended fan speed, swing and vane positions, room temperature, error codes, remote and per-mode locks, operating-mode force and energy consumption.

This page lists 51 BACnet objects for the Intesis IN770AIR***O000 for Midea commercial and VRF (700 Series Air Gateway) — 23 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 IN770AIR***O000 for Midea commercial and VRF (700 Series Air Gateway)

Integration in brief

Connect the Midea bus to the gateway, pick BACnet IP or BACnet MS/TP in Intesis MAPS, configure the units, 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.

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 IN770AIR***O000 for Midea commercial and VRF (700 Series Air Gateway) and exports what it actually has to Excel — free.

Questions about the Intesis IN770AIR***O000 for Midea commercial and VRF (700 Series Air Gateway)

How many BACnet points does the Intesis IN770AIR***O000 for Midea commercial and VRF (700 Series Air Gateway) have?

This list has 51 BACnet objects: 14 analog inputs, 2 analog outputs, 9 binary inputs, 11 binary outputs, 5 multi-state inputs, 10 multi-state outputs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Intesis IN770AIR***O000 for Midea commercial and VRF (700 Series Air Gateway) BACnet points are writable?

23 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 Intesis IN770AIR***O000 for Midea commercial and VRF (700 Series Air Gateway) BACnet documentation?

The source is 700 Series Air Gateway IN770AIR***O000 - Midea Commercial and VRF Systems to Modbus, KNX, BACnet, MQTT and Home Automation - User Manual, revision 2025-12-09 v1.0.22, published free by Intesis at https://www.hms-networks.com/docs/default-source/products/intesis/manuals-and-guides---manuals/user-manual-in770midxxxo000.pdf.

What are the minimum BACnet points to integrate the Intesis IN770AIR***O000 for Midea commercial and VRF (700 Series Air Gateway)?

Start with BO 100 UXX_On/Off_C (Start/stop indoor unit); MO 100 UXX_Mode_C (Mode command); AO 100 UXX_Setpoint_C (Setpoint command); MO 101 UXX_FanSpeed_C (Fan speed command (1 = auto)); BI 100 UXX_On/Off_S (Run status); AI 100 UXX_Setpoint_S (Setpoint in use); AI 101 UXX_Room Temperature (Indoor unit room temperature, °C); BI 102 UXX_Communication Error IU (Unit offline on the Midea bus); AI 102 UXX_Unit Error Code (Fault code (0 = no error)).

How do I enable BMS control of the Intesis IN770AIR***O000 for Midea commercial and VRF (700 Series Air Gateway)?

No enable point is documented. UXX_Remote control lock_C (BO 102) locks the remote controller of that unit.

How do I check these points on the real IN770AIR***O000 for Midea commercial and VRF (700 Series Air Gateway)?

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.
