LG MultiSITE MS8350 Room Controller (fan coil) BACnet points list

Updated 4 November 2026

Short answer

The MS8350 is LG's MultiSITE touchscreen room controller for fan coil units. It is a BACnet MS/TP application specific controller (B-ASC) with about 280 objects: room and outdoor temperature, setpoints, system and fan mode, fan and universal outputs, alarms, display and configuration values, Wi-Fi status and paired ZigBee wireless sensor objects.

This page lists 281 BACnet objects for the LG MultiSITE MS8350 Room Controller (fan coil) — 205 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from LG’s own free documentation, linked below.

BMS integration notes: LG MultiSITE MS8350 Room Controller (fan coil)

Integration in brief

Command occupancy with MV 10, mode with MV 16 and fan mode with MV 17, and write the occupied setpoints AV 39/AV 40. Read AV 100 room temperature, MI 33 effective occupancy and MV 112 control status.

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
MV 10	Occupancy Command	BMS occupancy: local, occupied or unoccupied	Command
MV 16	System Mode	Off / auto / cool / heat	Command
MV 17	Fan Mode	Fan mode: on / auto / smart	Command
AV 39	Occ. Heat	Occupied heating setpoint	Command
AV 40	Occ. Cool	Occupied cooling setpoint	Command
MV 112	Control Status	Current state: off, cooling or heating	Command
MI 33	Effective Occupancy	Actual occupancy state	Read
AV 100	Room Temperature	Space temperature used for control	Command
BV 37	Service Alarm	Service alarm from an input set to Service	Command

Enable & remote start

The BMS writes MV 10 Occupancy Command (1 = Loc. occ; 2 = Occupied; 3 = Unocc.) and MV 16 System Mode. MV 110 chooses whether local occupancy follows motion or the schedule.

Sensors & values from the BMS

The guide does not describe feeding room temperature from the BMS. MV 145 selects the wired, internal or a paired ZigBee wireless sensor, and MI 312 Effective Temperature Sensor shows which one is in use. Writing an AI present value only works with Out_Of_Service set TRUE.

Network setup

BACnet MS/TP baud rate is MV 8 (9600, 19200, 38400, 57600, 76800, 115200 or Auto; default Auto). Max_Master is writable, 0-127, default 127.
AV 10 COM Address holds the MS/TP address. Device Object_Identifier and Object_Name are writable; no default device instance is printed.
MI 317 BACnet IP Status shows whether BACnet IP is enabled; separate Wi-Fi objects report the Wi-Fi module state.
The controller is a B-ASC with COV, time synchronization and an internal schedule (SCHED-I-B); it does not support segmented requests or responses.

Watch out for

For the MS8350 the guide says writes at some priority levels go to EEPROM (locked at the controller and kept through a power cycle until released at the same priority or by Restore Factory Default) and others to RAM (lost on a power cycle), but it does not print which priority numbers fall in each group.
On the MS8350 the relinquish default is the value set at the thermostat and it survives power cycles; on the MS8650 the relinquish default of AV 100 and above is read-only.
Keep Read Property Multiple requests small; segmentation is not supported.

Integration notes

Access follows the guide's object-property tables: AV, AO, BV, BO and MSV present values are commandable, CSVs writable, and AI/MSI present values only writable while Out_Of_Service is TRUE.
The guide gives no description column, only default, range and a units/state column; descriptions here show the printed default and range.
Some object names print the subscript 2 of CO2 out of place (e.g. 'CO level 2'); they are written as CO2 here (AV 106 'CO2 level').
Wireless Device objects only report data for paired ZigBee Pro sensors.
The guide mentions 10 program (PG) objects for LUA4RC scripts but does not list them.

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 MultiSITE MS8350 Room Controller (fan coil) 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 LG MultiSITE MS8350 Room Controller (fan coil)

How many BACnet points does the LG MultiSITE MS8350 Room Controller (fan coil) have?

This list has 281 BACnet objects: 30 analog inputs, 6 analog outputs, 68 analog values, 7 binary inputs, 9 binary outputs, 24 binary values, 39 multi-state inputs, 88 multi-state values, 10 characterstring values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which LG MultiSITE MS8350 Room Controller (fan coil) BACnet points are writable?

205 of the 281 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 LG MultiSITE MS8350 Room Controller (fan coil) BACnet documentation?

The source is MultiSITE MS8000 Series Room Controllers BACnet Integration Guide (MS8350 VUCQMS8350, MS8650 VUCQMS8650) (UM_MultiSITE_MS8000_Series_BACnet_Integration_05_20), revision 2020-05, published free by LG at https://media.us.lg.com/m/11d3a44fc9cab7aa/original/UM_MultiSITE_MS8000_Series_BACnet_Integration-pdf.pdf.

What are the minimum BACnet points to integrate the LG MultiSITE MS8350 Room Controller (fan coil)?

Start with MV 10 Occupancy Command (BMS occupancy: local, occupied or unoccupied); MV 16 System Mode (Off / auto / cool / heat); MV 17 Fan Mode (Fan mode: on / auto / smart); AV 39 Occ. Heat (Occupied heating setpoint); AV 40 Occ. Cool (Occupied cooling setpoint); MV 112 Control Status (Current state: off, cooling or heating); MI 33 Effective Occupancy (Actual occupancy state); AV 100 Room Temperature (Space temperature used for control); BV 37 Service Alarm (Service alarm from an input set to Service).

How do I enable BMS control of the LG MultiSITE MS8350 Room Controller (fan coil)?

The BMS writes MV 10 Occupancy Command (1 = Loc. occ; 2 = Occupied; 3 = Unocc.) and MV 16 System Mode. MV 110 chooses whether local occupancy follows motion or the schedule.

Can the BMS supply sensor values to the LG MultiSITE MS8350 Room Controller (fan coil)?

How do I check these points on the real MultiSITE MS8350 Room Controller (fan coil)?

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.
