Daikin Applied MicroTech II Vertical Self-Contained Unit Controller (SWP / SWT) BACnet points list

Updated 6 November 2026

Short answer

The MicroTech II controller on SWP and SWT vertical self-contained units talks BACnet IP or BACnet MS/TP through a communication module (LonWorks is the other option). The table covers unit status, application and occupancy commands, zone and discharge air setpoints, water and air temperatures, duct and building pressure, waterside and airside economizer data, SCC dehumidification, a keypad schedule and calendar, and alarm read and clear objects.

This page lists 67 BACnet objects for the Daikin Applied MicroTech II Vertical Self-Contained Unit Controller (SWP / SWT) — 30 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Daikin Applied’s own free documentation, linked below.

BMS integration notes: Daikin Applied MicroTech II Vertical Self-Contained Unit Controller (SWP / SWT)

Integration in brief

Set switch S7 to AUTO and Control Mode to AUTO at the keypad. Leave Occupancy Mode on Auto and command occupancy with the Occupancy Scheduler Input BV at a priority above 15 (e.g. 8). Use Application Mode for on/off, write setpoints as needed and read status, temperatures and the alarm notification values.

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.

Enable & remote start

Set rocker switch S7 to AUTO and the keypad Control Mode to AUTO (password 4545). Application Mode (AV 3715) then turns the unit off or selects heat/cool, heat only, cool only or fan only; Emergency Override Mode Flag (AV 3720) = 1 shuts it off from the network. Occupancy Mode (AV 3930) is an override and should stay Auto.

Heartbeat & communication loss

The guide's receive heartbeat (occupancy scheduler input, application mode, fan capacity, building static pressure, outdoor, return and space temperature, humidity) is a LonWorks feature with no BACnet equivalent. Over BACnet, an input written with Out_Of_Service TRUE keeps its last value if communication is lost.

Sensors & values from the BMS

Space temperature (AI 120), outdoor air temperature (AI 145) and building static pressure (AI 1425) accept BMS values after Out_Of_Service is set TRUE. Space Setpoint Type (AV 3725) must be Network for network setpoint control on SCC units.

Integration notes

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 MicroTech II Vertical Self-Contained Unit Controller (SWP / SWT) and exports what it actually has to Excel — free.

Questions about the Daikin Applied MicroTech II Vertical Self-Contained Unit Controller (SWP / SWT)

How many BACnet points does the Daikin Applied MicroTech II Vertical Self-Contained Unit Controller (SWP / SWT) have?

This list has 67 BACnet objects: 10 analog inputs, 45 analog values, 2 binary inputs, 8 binary values, 1 calendar, 1 schedule. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Daikin Applied MicroTech II Vertical Self-Contained Unit Controller (SWP / SWT) BACnet points are writable?

30 of the 67 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 Applied MicroTech II Vertical Self-Contained Unit Controller (SWP / SWT) BACnet documentation?

The source is MicroTech II Vertical Self-Contained Unit Controller Protocol Information, BACnet Networks, LonWorks Networks (ED 15061-6), revision 2012-05, published free by Daikin Applied at https://tahoeweb.daikinapplied.com/api/general/DownloadDocumentByName/media/ED15061-6.pdf.

What are the minimum BACnet points to integrate the Daikin Applied MicroTech II Vertical Self-Contained Unit Controller (SWP / SWT)?

Start with AV 3715 Application Mode (Off / heat-cool / heat only / cool only / fan only); BV 1380 Occupancy Scheduler Input (Occupied command; write at priority 8, not 15); AV 3720 Emergency Override Mode Flag (Network shutdown (1 = off)); AV 3765 Occupied Cooling Setpoint (Occupied cooling setpoint); AV 3820 Occupied Heating Setpoint (Occupied heating setpoint); AV 3840 Duct Static Pressure Setpoint (Duct static pressure setpoint (DAC units)); BV 4150 Alarm, Faults: Clear All (Fault alarm flag; write to clear faults); AV 3915 Unit Status (Unit operating state); AI 135 Discharge Air Temperature (Discharge air temperature); AV 5328 Alarms-Fault Individual Notification (Highest-priority active fault number).

How do I enable BMS control of the Daikin Applied MicroTech II Vertical Self-Contained Unit Controller (SWP / SWT)?

Set rocker switch S7 to AUTO and the keypad Control Mode to AUTO (password 4545). Application Mode (AV 3715) then turns the unit off or selects heat/cool, heat only, cool only or fan only; Emergency Override Mode Flag (AV 3720) = 1 shuts it off from the network. Occupancy Mode (AV 3930) is an override and should stay Auto.

Does the Daikin Applied MicroTech II Vertical Self-Contained Unit Controller (SWP / SWT) need a BACnet heartbeat or have a communication timeout?

The guide's receive heartbeat (occupancy scheduler input, application mode, fan capacity, building static pressure, outdoor, return and space temperature, humidity) is a LonWorks feature with no BACnet equivalent. Over BACnet, an input written with Out_Of_Service TRUE keeps its last value if communication is lost.

Can the BMS supply sensor values to the Daikin Applied MicroTech II Vertical Self-Contained Unit Controller (SWP / SWT)?

Space temperature (AI 120), outdoor air temperature (AI 145) and building static pressure (AI 1425) accept BMS values after Out_Of_Service is set TRUE. Space Setpoint Type (AV 3725) must be Network for network setpoint control on SCC units.

How do I check these points on the real MicroTech II Vertical Self-Contained Unit Controller (SWP / SWT)?

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.
