Daikin iLINQ DDC Controller (BACnet MS/TP and BACnet IP) BACnet points list

Updated 6 November 2026

Short answer

The iLINQ DDC controller on Daikin light commercial packaged units talks BACnet MS/TP (port J25 BMS2) or BACnet IP (Ethernet) without extra hardware. Its object list covers space, supply and outdoor conditions, refrigerant pressures, setpoints, blower and economizer settings, network sensor inputs, relay status, individual alarm flags and multistate schedule, mode and configuration objects.

This page lists 215 BACnet objects for the Daikin iLINQ DDC Controller (BACnet MS/TP and BACnet IP) — 76 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Daikin’s own free documentation, linked below.

BMS integration notes: Daikin iLINQ DDC Controller (BACnet MS/TP and BACnet IP)

Integration in brief

Pick MS/TP or IP in the communication settings, set the instance ID (and MAC/baud for MS/TP) and set Update to Yes. Command occupancy by writing ScheduleSource (MV 0) and write OccCoolSP / OccHeatSP; read space and supply air temperature, HVAC mode, blower status and AlarmDO.

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 0	ScheduleSource	3 = Force Occupied, 4 = Force Unoccupied from the BAS	Write
AV 17	OccCoolSP	Occupied cooling setpoint, °F	Write
AV 18	OccHeatSP	Occupied heating setpoint, °F	Write
MV 2	HVACMode_BacMsv	Current HVAC mode	Read
BV 6	BlowerStage1	Blower stage 1 relay on/off	Read
AI 0	SpaceTemp	Space temperature, °F	Read
AI 1	SupplyAirTemp	Supply air temperature, °F	Read
BV 20	AlarmDO	Any alarm active	Read

Enable & remote start

To schedule from the BAS, write 3 (Force Occupied) or 4 (Force Unoccupied) to ScheduleSource (MV 0); the onboard schedule and optimal start/stop are then ignored. If PushButtonOvrDuration (AV 79) is above 0, the space sensor button or the Remote Start Stop input can still give a temporary override.

Sensors & values from the BMS

Space temperature, space humidity, outdoor temperature, outdoor humidity and space CO2 can come from the BAS through AV 12-16 once each source is set to Network at the LCD or web interface (the source objects MV 9-13 are read-only over BACnet).

Network setup

Communication type defaults to BACnet MS/TP; MS/TP wires to terminal J25 BMS2, BACnet IP uses either Ethernet port.
Defaults: instance ID 15000, baud 38400 (9600-76800), MAC address 1, Max Master 127.
Settings take effect when Update is set to Yes, which restarts the controller.
COV subscriptions are supported; COV increments of AIs and AVs can be changed from the BACnet client.

Watch out for

The active setpoints (AV 6/7) are read-only and include local adjustment, load shedding and unoccupied offsets; write OccCoolSP / OccHeatSP instead.
UnitOccupiedStartDelay (AV 78) can stagger start-up when many units are commanded occupied together.
Offsets, bands, delays and calibration AVs are setup values; don't write them cyclically.

Integration notes

Access is from the R/W column. Many writable AVs are setup values (offsets, bands, delays, calibration).
Temperature offsets, bands and calibration values are temperature differences (printed as ∆°F); they are shown here as °F.
AV 93-100 mirror the software revision and installed equipment counts.
Binary values 27-68 are individual alarm flags; AlarmDO (BV 20) is true when any alarm is active.
The sensor source selectors (MV 9-13) are read-only over BACnet; set them at the LCD or web interface.
The table prints state 7 of HVACMode_BacMsv as "Force"; the rest of the text is not shown.

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 Daikin iLINQ DDC Controller (BACnet MS/TP and BACnet IP) and exports what it actually has to Excel — free.

Questions about the Daikin iLINQ DDC Controller (BACnet MS/TP and BACnet IP)

How many BACnet points does the Daikin iLINQ DDC Controller (BACnet MS/TP and BACnet IP) have?

This list has 215 BACnet objects: 12 analog inputs, 101 analog values, 19 binary inputs, 69 binary values, 14 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Daikin iLINQ DDC Controller (BACnet MS/TP and BACnet IP) BACnet points are writable?

76 of the 215 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 Daikin iLINQ DDC Controller (BACnet MS/TP and BACnet IP) BACnet documentation?

The source is Daikin iLINQ BACnet Design Guide (BDG-ILINQA), published free by Daikin at https://daikincomfort.com/docs/default-source/daikin-ilinq-controller/bdg-ilinq.pdf.

What are the minimum BACnet points to integrate the Daikin iLINQ DDC Controller (BACnet MS/TP and BACnet IP)?

Start with MV 0 ScheduleSource (3 = Force Occupied, 4 = Force Unoccupied from the BAS); AV 17 OccCoolSP (Occupied cooling setpoint, °F); AV 18 OccHeatSP (Occupied heating setpoint, °F); MV 2 HVACMode_BacMsv (Current HVAC mode); BV 6 BlowerStage1 (Blower stage 1 relay on/off); AI 0 SpaceTemp (Space temperature, °F); AI 1 SupplyAirTemp (Supply air temperature, °F); BV 20 AlarmDO (Any alarm active).

How do I enable BMS control of the Daikin iLINQ DDC Controller (BACnet MS/TP and BACnet IP)?

Can the BMS supply sensor values to the Daikin iLINQ DDC Controller (BACnet MS/TP and BACnet IP)?

How do I check these points on the real Daikin iLINQ DDC Controller (BACnet MS/TP and BACnet IP)?

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.
