Daikin Applied MicroTech II Applied Rooftop Unit Controller BACnet points list

Updated 4 November 2026

Short answer

The older MicroTech II applied rooftop controller connects to BACnet IP or BACnet MS/TP through a plug-in communication module (LonWorks modules also exist). It exposes a fixed set of standard objects, mostly analog values carrying numbered enumerations, covering unit status, application mode, occupancy, temperatures, duct and building static pressure, fan capacities, zone and discharge setpoints, outdoor air damper, economizer, energy recovery, dehumidification, schedule and alarms.

This page lists 75 BACnet objects for the Daikin Applied MicroTech II Applied Rooftop Unit Controller — 37 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 Applied Rooftop Unit Controller

Integration in brief

Set switch S7 to AUTO and Control Mode to AUTO at the keypad. With Occupancy Mode left at Auto, the BMS commands occupancy through the Occupancy Scheduler Input BV at a priority higher than 15, turns the unit off with Application Mode or the Emergency Override flag, and writes setpoints at priority 16.

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

Put rocker switch S7 in AUTO and set Control Mode to AUTO at the keypad (password 4545). Leave Occupancy Mode (AV 3825) at Auto and command occupancy with the Occupancy Scheduler Input (BV 1455). Application Mode (AV 3605) = Off or Emergency Override Mode Flag (AV 3610) = Off shuts the unit down. For network setpoint control set Space Setpoint Type (AV 3615) to Keypad/Network.

Heartbeat & communication loss

No BACnet heartbeat point is given; the receive-heartbeat defaults in the doc apply to the LonWorks network variables. A BACnet value written to an out-of-service input (space, outdoor air temperature, building static pressure) is held at its last value if communication is lost.

Sensors & values from the BMS

Space Temperature (AI 100), Outdoor Air Temperature (AI 125) and Building Static Pressure (AI 1505) accept a BMS value once their Out_Of_Service property is set to TRUE; the controller keeps the last value written if communication is lost. Remote fan capacities are written to AV 3725 / AV 3740 when the matching control flag (AV 3720 / AV 3750) is set to Position.

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 Applied Rooftop Unit Controller and exports what it actually has to Excel — free.

Questions about the Daikin Applied MicroTech II Applied Rooftop Unit Controller

How many BACnet points does the Daikin Applied MicroTech II Applied Rooftop Unit Controller have?

This list has 75 BACnet objects: 8 analog inputs, 56 analog values, 1 binary input, 4 binary outputs, 4 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 Applied Rooftop Unit Controller BACnet points are writable?

37 of the 75 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 Applied Rooftop Unit Controller BACnet documentation?

The source is MicroTech II Applied Rooftop Unit Controller Protocol Information (ED 15060-13), revision 2012-05, published free by Daikin Applied at https://tahoeweb.daikinapplied.com/api/general/DownloadDocumentByName/media/ED15060-13.pdf/.

What are the minimum BACnet points to integrate the Daikin Applied MicroTech II Applied Rooftop Unit Controller?

Start with BV 1455 Occupancy Scheduler Input (Occupied (1) / unoccupied (0) command from the BMS); AV 3610 Emergency Override Mode Flag (Network shutdown: 1 = Off, 0 = Normal); AV 3605 Application Mode (0=Auto, 1=Off, 2=HeatOnly, 3=CoolOnly, 4=FanOnly); AV 3655 Occupied Cooling Setpoint (Occupied cooling setpoint); AV 3710 Occupied Heating Setpoint (Occupied heating setpoint); AV 3630 Discharge Air Cooling Setpoint (Discharge air cooling setpoint (DAC units)); AV 3810 Unit Status (Current operating state (enumerated)); AI 115 Discharge Air Temperature (Discharge air temperature); AV 3790 Duct Static Pressure (Duct static pressure, in. w.c); BV 4150 Alarm, Faults: Clear All (Fault alarm active; write 0 to clear).

How do I enable BMS control of the Daikin Applied MicroTech II Applied Rooftop Unit Controller?

Put rocker switch S7 in AUTO and set Control Mode to AUTO at the keypad (password 4545). Leave Occupancy Mode (AV 3825) at Auto and command occupancy with the Occupancy Scheduler Input (BV 1455). Application Mode (AV 3605) = Off or Emergency Override Mode Flag (AV 3610) = Off shuts the unit down. For network setpoint control set Space Setpoint Type (AV 3615) to Keypad/Network.

Does the Daikin Applied MicroTech II Applied Rooftop Unit Controller need a BACnet heartbeat or have a communication timeout?

No BACnet heartbeat point is given; the receive-heartbeat defaults in the doc apply to the LonWorks network variables. A BACnet value written to an out-of-service input (space, outdoor air temperature, building static pressure) is held at its last value if communication is lost.

Can the BMS supply sensor values to the Daikin Applied MicroTech II Applied Rooftop Unit Controller?

Space Temperature (AI 100), Outdoor Air Temperature (AI 125) and Building Static Pressure (AI 1505) accept a BMS value once their Out_Of_Service property is set to TRUE; the controller keeps the last value written if communication is lost. Remote fan capacities are written to AV 3725 / AV 3740 when the matching control flag (AV 3720 / AV 3750) is set to Position.

How do I check these points on the real MicroTech II Applied Rooftop Unit Controller?

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.
