Daikin DKN Plus Interface AZAI6WSPDKC (BACnet MS/TP) BACnet points list
Updated 4 November 2026
The DKN Plus Interface is a Wi-Fi controller that wires to a single Daikin indoor unit (P1P2 or S21 connection) and also acts as a BACnet MS/TP slave on its RS-485 port. It exposes 12 objects: on/off, setpoint, room and return temperature, mode, fan speed, louvers and error status. The manual carries Airzone branding and its PICS names the vendor as ALTRA S.L.; the BACnet address is set from the DKN Cloud NA app.
This page lists 12 BACnet objects for the Daikin DKN Plus Interface AZAI6WSPDKC (BACnet MS/TP) — 6 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 DKN Plus Interface AZAI6WSPDKC (BACnet MS/TP)
Give the interface its MS/TP address from the DKN Cloud NA app, then write On/Off (BV 0), Modes (MV 0), Setpoint (AV 0) and Speeds (MV 1). Read Localtemp and the IU communication and error objects for status. Ignore any object whose Out_Of_Service is TRUE.
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 |
|---|---|---|---|
| BV 0 | On/Off | Indoor unit on/off (1 = on) | Write |
| MV 0 | Modes | Operating mode; codes differ in the manual | Write |
| AV 0 | Setpoint | Indoor unit setpoint | Write |
| MV 1 | Speeds | Fan speed: 0 auto, 1-3 speed | Write |
| AV 1 | Localtemp | Room temperature | Write |
| BI 0 | IU communication | 0 = no communication with indoor unit | Read |
| BI 1 | IU error | Indoor unit error active | Read |
| CSV 1 | Errors | Indoor unit error code | Read |
Sensors & values from the BMS
On a P1P2 connection the BMS can write the room temperature to Localtemp (AV 1); on S21 it is read only and equals the return temperature.
Network setup
- The MS/TP slave address is entered in the DKN Cloud NA app (Configure Units > Communication protocol > BACnet).
- RS-485 port: 300 to 115200 bps, 8 data bits, even parity, 1 stop bit.
Watch out for
- Mode codes in the object list and the detailed description do not match; verify by reading MV 0 while changing mode at the unit.
- Objects not supported by the connected unit stay Out_Of_Service; their values are invalid.

Object ID lookup: Daikin DKN Plus Interface point IDs by name
Integration notes
- Object availability depends on the connected unit; an object whose Out_Of_Service is TRUE is not present on that system and its value is not valid.
- The object list gives Modes (MV 0) as 1 Auto, 2 Cooling, 3 Heating, 4 Fan, 5 Dry, but the detailed description lists 0 Stop, 2 Cooling, 3 Heating, 4 Dry, 6 Ventilation. Check on site.
- The object list marks Speeds (MV 1) R/W, while the detailed description calls fan speed read only.
- Localtemp (AV 1) is writable only on a P1P2 connection; on S21 it equals the return temperature.
- Temperature units are not stated in the object list.
- The PICS in the same document names the product 'DZK Plus Interface' and the vendor ALTRA S.L.
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 DKN Plus Interface AZAI6WSPDKC (BACnet MS/TP) and exports what it actually has to Excel — free.

Questions about the Daikin DKN Plus Interface AZAI6WSPDKC (BACnet MS/TP)
How many BACnet points does the Daikin DKN Plus Interface AZAI6WSPDKC (BACnet MS/TP) have?
This list has 12 BACnet objects: 1 analog input, 2 analog values, 3 binary inputs, 1 binary output, 1 binary value, 3 multi-state values, 1 characterstring value. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Daikin DKN Plus Interface AZAI6WSPDKC (BACnet MS/TP) BACnet points are writable?
6 of the 12 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 DKN Plus Interface AZAI6WSPDKC (BACnet MS/TP) BACnet documentation?
The source is DKN Plus Interface AZAI6WSPDKC Integration manual (BACnet) (AZAI6WSPDKC), revision 2021-02 (PICS date), published free by Daikin at https://daikincomfort.com/docs/default-source/dkn-plus-interface/om-om_bacnet_azai6wspdkc_10202.pdf.
What are the minimum BACnet points to integrate the Daikin DKN Plus Interface AZAI6WSPDKC (BACnet MS/TP)?
Start with BV 0 On/Off (Indoor unit on/off (1 = on)); MV 0 Modes (Operating mode; codes differ in the manual); AV 0 Setpoint (Indoor unit setpoint); MV 1 Speeds (Fan speed: 0 auto, 1-3 speed); AV 1 Localtemp (Room temperature); BI 0 IU communication (0 = no communication with indoor unit); BI 1 IU error (Indoor unit error active); CSV 1 Errors (Indoor unit error code).
Can the BMS supply sensor values to the Daikin DKN Plus Interface AZAI6WSPDKC (BACnet MS/TP)?
On a P1P2 connection the BMS can write the room temperature to Localtemp (AV 1); on S21 it is read only and equals the return temperature.
How do I check these points on the real DKN Plus Interface AZAI6WSPDKC (BACnet MS/TP)?
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.
