Price Industries UMC3 underfloor controller BACnet points list
Updated 6 November 2026
UMC3 is Price's controller for underfloor air terminals on BACnet MS/TP. The points list has 38 objects: room and supply air temperatures, 0-10 V heat/cool inputs, setpoints and limits, damper and LFGH damper positions, PI load, auxiliary output settings and BMS override values for setpoint, room temperature, occupancy and lights.
This page lists 38 BACnet objects for the Price Industries UMC3 underfloor controller — 22 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Price Industries’s own free documentation, linked below.

BMS integration notes: Price Industries UMC3 underfloor controller
Use AV 30 Net Occupancy, AV 28 Net Setpoint and, if needed, AV 29 to drive the controller from the BMS; read AV 2 Occupancy, AI 1 room temperature, AV 14 room load and AV 18 damper position.
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 |
|---|---|---|---|
| AV 30 | Net Occupancy | BMS occupancy: 0 normal, 1 occupied, 2 unoccupied | Write |
| AV 28 | Net Setpoint | BMS setpoint override, 0 = none | Write |
| AV 29 | Net Room Temperature | BMS room temperature, 0 = none | Write |
| AV 2 | Occupancy | Current occupancy: 0 unocc, 1 occ | Read |
| AI 1 | Room Temperature | Room temperature | Read |

| AV 14 | Controller Status | Room load: + heating, - cooling, % | Read |
| AV 18 | Current Damper Position | Damper position, % (999 = calibrating) | Read |
Enable & remote start
AV 30 Net Occupancy: 0 = normal operation, 1 = force occupied, 2 = force unoccupied. AV 1 selects thermostat/network control or the 0-10 V heat/cool input signals.
Sensors & values from the BMS
AV 28 Net Setpoint and AV 29 Net Room Temp override the thermostat setpoint and room temperature from the BMS (0 = normal operation, no override); AV 30 Net Occupancy forces occupied (1) or unoccupied (2).
Network setup
- BACnet MS/TP; Price default baud rate is 76800.

Integration notes
- Instances named N/A in the list (unused: AI 2, AI 6, AI 7) are left out.
- Several AV objects carry coded values; the codes are listed in the states field.
- The list also marks which values are retained after a power failure.
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 UMC3 underfloor controller and exports what it actually has to Excel — free. New to BACnet?

Questions about the Price Industries UMC3 underfloor controller
How many BACnet points does the Price Industries UMC3 underfloor controller have?
This list has 38 BACnet objects: 5 analog inputs, 33 analog values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Price Industries UMC3 underfloor controller BACnet points are writable?
22 of the 38 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 Price Industries UMC3 underfloor controller BACnet documentation?
The source is BACnet points list for UMC3 firmware v1.19.0, revision Rev 0, published free by Price Industries at https://priceindustries.com/wp-content/uploads/BACnet-points-list-v1.19.0-UMC3-Rev-0.pdf.
What are the minimum BACnet points to integrate the Price Industries UMC3 underfloor controller?
Start with AV 30 Net Occupancy (BMS occupancy: 0 normal, 1 occupied, 2 unoccupied); AV 28 Net Setpoint (BMS setpoint override, 0 = none); AV 29 Net Room Temperature (BMS room temperature, 0 = none); AV 2 Occupancy (Current occupancy: 0 unocc, 1 occ); AI 1 Room Temperature (Room temperature); AV 6 Room Setpoint (Current room setpoint); AV 14 Controller Status (Room load: + heating, - cooling, %); AV 18 Current Damper Position (Damper position, % (999 = calibrating)).
How do I enable BMS control of the Price Industries UMC3 underfloor controller?
AV 30 Net Occupancy: 0 = normal operation, 1 = force occupied, 2 = force unoccupied. AV 1 selects thermostat/network control or the 0-10 V heat/cool input signals.
Can the BMS supply sensor values to the Price Industries UMC3 underfloor controller?
AV 28 Net Setpoint and AV 29 Net Room Temp override the thermostat setpoint and room temperature from the BMS (0 = normal operation, no override); AV 30 Net Occupancy forces occupied (1) or unoccupied (2).
How do I check these points on the real UMC3 underfloor 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.
