LG ACP BACnet gateway - AHU kit objects (PQNFB17C0 / PQNFB17C1) BACnet points list
Updated 7 November 2026Unofficial source
The ACP BACnet gateway serves each LG AHU on its LG-NET as a fixed block of 53 BACnet IP objects on the gateway's AHU device (Device ID + 2). Besides on/off, mode, setpoint and alarm, the AHU block carries humidity control, supply, outdoor and mixed air readings, CO2, fan and heater status and per-mode damper positions. The same manual's indoor, ventilation and outdoor tables are in the separate ACP BACnet entry.
This page lists 53 BACnet objects for the LG ACP BACnet gateway - AHU kit objects (PQNFB17C0 / PQNFB17C1) — 18 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from a copy of LG’s documentation hosted by SupplyHouse.com, not by LG itself, so treat it as unofficial.

BMS integration notes: LG ACP BACnet gateway - AHU kit objects (PQNFB17C0 / PQNFB17C1)
Give the ACP BACnet an IP address and Device ID, let it find the AHU on LG-NET, then read the AHU device (Device ID + 2) at 131072 + address x 256. Map on/off, mode and setpoint, then room, supply and outdoor readings and the alarm.
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.

Network setup
- Default Device ID 9000; the AHU device is Device ID + 2.
- Device ID and network settings are set from the ACP's front-panel menu.
- Wire the AHU RS-485 line to CH5 on the ACP BACnet (indoor-unit lines use CH1-CH4).
Watch out for
- The on/off command is sent to the unit whatever its current state.
- Mode commands are ignored by a unit that does not hold the mode-select right.

Integration notes
- Instance = 2 x 65536 + unit address x 256 + point number (product type 2 = AHU). Instances here are for address 00, so point 1 = BO 131073; AHU address 01 point 1 = 131329.
- AHU objects sit on their own BACnet device: the gateway Device ID (default 9000) + 2.
- Point numbers 9-12, 17 and 18 are unused in the AHU table.
- Temperature and humidity readings are printed with ranges only (-127 to 127, 30-90) and no units. CO2 reads in tens of ppm (20 = 200 ppm).
- Damper points carry a 0-90 range with no unit stated.
- The manual has no read/write column: access is inferred from the object type and the Setting/Status labels.
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 ACP BACnet gateway - AHU kit objects (PQNFB17C0 / PQNFB17C1) and exports what it actually has to Excel — free.

Questions about the LG ACP BACnet gateway - AHU kit objects (PQNFB17C0 / PQNFB17C1)
How many BACnet points does the LG ACP BACnet gateway - AHU kit objects (PQNFB17C0 / PQNFB17C1) have?
This list has 53 BACnet objects: 23 analog inputs, 11 analog values, 11 binary inputs, 5 binary outputs, 1 binary value, 1 multi-state input, 1 multi-state output. The exact set on a given unit depends on its firmware, installed options and configuration.
Which LG ACP BACnet gateway - AHU kit objects (PQNFB17C0 / PQNFB17C1) BACnet points are writable?
18 of the 53 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 LG ACP BACnet gateway - AHU kit objects (PQNFB17C0 / PQNFB17C1) BACnet documentation?
LG does not publish it on its own website. This list comes from BACnet Gateway (ACP BACnet) Installation/User Manual (MFL67709501), revision 2014 (copyright date), a copy hosted by SupplyHouse.com at https://s3.amazonaws.com/s3.supplyhouse.com/product_files/LG-PQNFB17C1-Install-Instructions.pdf. Ask LG or its representative for the current revision.
What are the minimum BACnet points to integrate the LG ACP BACnet gateway - AHU kit objects (PQNFB17C0 / PQNFB17C1)?
Start with BO 131073 StartStopCommand_XXX (On/off (131073 + AHU address x 256)); MO 131079 ModeCommand_XXX (1 Cool, 2 Dry, 3 Fan, 4 Heat); AV 131085 SetRoomTemp_XXX (Room temperature setpoint); BI 131074 StartStopStatus_XXX (Running status); AI 131086 RoomTemp_XXX (Room temperature); AI 131100 SupplyTempStatus_XXX (Supply air temperature); BI 131087 Alarm_XXX (Unit alarm); AI 131088 MalfunctionCode_XXX (LG error code).
How do I check these points on the real ACP BACnet gateway - AHU kit objects (PQNFB17C0 / PQNFB17C1)?
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.
