LG ACP BACnet gateway - AWHP (air-to-water heat pump) objects (PQNFB17C0 / PQNFB17C1) BACnet points list
Updated 7 November 2026Unofficial source
The ACP BACnet gateway serves each LG air-to-water heat pump on its LG-NET as a fixed block of 23 BACnet IP objects on the gateway's AWHP device (Device ID + 4). The block has run/stop, mode, room, hot water and leaving water setpoints, hot water on/off, water and tank temperatures, alarm and error code.
This page lists 23 BACnet objects for the LG ACP BACnet gateway - AWHP (air-to-water heat pump) objects (PQNFB17C0 / PQNFB17C1) — 7 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 - AWHP (air-to-water heat pump) objects (PQNFB17C0 / PQNFB17C1)
Give the ACP BACnet an IP address and Device ID, let it find the heat pump on LG-NET, then read the AWHP device (Device ID + 4) at 262144 + address x 256. Map run/stop, mode and the setpoint the unit controls on (air or water, see AirWaterFlag), then hot water and alarms.
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 AWHP device is Device ID + 4.
- Device ID and network settings are set from the ACP's front-panel menu.
Watch out for
- AirWaterFlag shows whether the unit controls on room air or water temperature; write the matching setpoint.

Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.
Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.

Integration notes
- Instance = 4 x 65536 + unit address x 256 + point number (product type 4 = AWHP). Instances here are for address 00, so point 1 = BO 262145.
- AWHP objects sit on their own BACnet device: the gateway Device ID (default 9000) + 4.
- The AWHP table prints no units, and no state texts for the hot water on/off points (18, 19).
- 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 - AWHP (air-to-water heat pump) objects (PQNFB17C0 / PQNFB17C1) and exports what it actually has to Excel — free.

Questions about the LG ACP BACnet gateway - AWHP (air-to-water heat pump) objects (PQNFB17C0 / PQNFB17C1)
How many BACnet points does the LG ACP BACnet gateway - AWHP (air-to-water heat pump) objects (PQNFB17C0 / PQNFB17C1) have?
This list has 23 BACnet objects: 9 analog inputs, 3 analog outputs, 6 binary inputs, 3 binary outputs, 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 - AWHP (air-to-water heat pump) objects (PQNFB17C0 / PQNFB17C1) BACnet points are writable?
7 of the 23 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 - AWHP (air-to-water heat pump) 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 - AWHP (air-to-water heat pump) objects (PQNFB17C0 / PQNFB17C1)?
Start with BO 262145 StartStopCommand_XXX (Run/stop (262145 + AWHP address x 256)); BO 262162 HotWaterCommand_XXX (Hot water on/off); MO 262149 ModeCommand_XXX (1 Cool, 2 Heat, 3 Auto); AO 262151 SetRoomTempCommand_XXX (Room temperature setpoint); AO 262155 SetPipeOutWaterTempCommand_XXX (Leaving water setpoint); AO 262153 SetHotWaterTempCommand_XXX (Hot water setpoint); BI 262146 StartStopStatus_XXX (Running status); AI 262165 TankTempStatus_XXX (Water tank temperature); BI 262160 Alarm_XXX (Unit alarm); AI 262161 MalfunctionCode_XXX (LG error code).
How do I check these points on the real ACP BACnet gateway - AWHP (air-to-water heat pump) 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.
