York Millennium / Series 40 Packaged Rooftop Units 25-40 Ton with IPU Control BACnet points list
Updated 7 November 2026
The IPU controller in YORK Millennium / Series 40 25-40 ton rooftop units serves BACnet MS/TP (BACnet IP through an optional FieldServer gateway) and Modbus. The BAS can command occupancy, unit stop, fan, ventilation, heating and the Y1/Y2/W1/W2 calls, and write zone, supply air, duct static, building pressure and economizer setpoints and a BAS zone temperature. Read-only points cover temperatures, humidity, CO2, static pressures, damper and VFD outputs, compressor and heat stage status, run hours, faults and the unit mode.
This page lists 146 BACnet objects for the York Millennium / Series 40 Packaged Rooftop Units 25-40 Ton with IPU Control — 61 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from York’s own free documentation, linked below.

BMS integration notes: York Millennium / Series 40 Packaged Rooftop Units 25-40 Ton with IPU Control
Set the MAC address on the IPU (the device instance follows as 23000 + MAC), then command occupancy (AV 88) and write the zone or supply air setpoints. Use UNIT_STOP (AV 93) for a BAS shutdown, and read supply fan status, supply and zone temperatures, the unit mode and the fault flags.
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.

| AV 93 | UNIT_STOP | Unit stop (1 = stopped, 0 = normal) | Write |

Enable & remote start
OCCUPNCY_CMD (AV 88) sets occupied/unoccupied from the BAS and UNIT_STOP (AV 93) shuts the unit down (0 = normal, 1 = stopped). OCC_MODE (BI 35) shows the resulting occupancy.
Sensors & values from the BMS
ZONE_TMP_BAS (AV 40) takes the zone temperature from the BAS when the control method is set to Comm Zone Temp. CO2 inside (AV 43), under-floor temperature and humidity (AV 36/37) and the duct static and supply air resets (AV 5, AV 28) are also BAS inputs; several must be enabled with the Service key first.
Network setup
- The default device instance is 23000 plus the MAC address (MAC 10 gives 23010); a DE modifier address and offset can set another instance.
- The MAC address is set with the IPU MAC switches or the P1 Manual MAC Address parameter (0-127); P1 baud rate 1200 to 76800.
- BACnet IP needs the FieldServer FS-B2010-02-01Y gateway.
Watch out for
- BAS-enabled inputs such as CO2 inside and under-floor values only take effect after they are enabled with the Service key.
- HEAT_ENABLE (AV 83) is inverted: 0 = enabled, 1 = disabled.

Integration notes
- Access is from the READ/WRITE column; descriptions are the user interface names from the table. Points marked FlexSys, VAV or CV only exist on those units.
- Rows the table marks "this feature is not available on this unit" (43 objects, for example 3rd-stage compressors, condenser fans and suction sensors) are left out.
- Fifteen on/off BAS commands (comfort and continuous ventilation, fan G, heating enable and valve action, morning warm-up, smoke purge 1-3, ventilation control, W1/W2 and Y1/Y2 calls) are printed as AV(BV) nn; they are listed here as AV nn.
- The smoke purge BAS commands (AV 90-92) are described as 0 = off, 1 = off in the table; the state text is left blank.
- The Series 40 IOM (LD14136) prints the same table; both documents point to this list.
- Same IPU object map as the Series 100 YPAL lists in this library: every instance here also appears there, but this table drops the objects not available on 25-40 ton units and spells some names differently (for example C02_INSIDE, ZONE_TMP_BAS).
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 Millennium / Series 40 Packaged Rooftop Units 25-40 Ton with IPU Control and exports what it actually has to Excel — free.

Questions about the York Millennium / Series 40 Packaged Rooftop Units 25-40 Ton with IPU Control
How many BACnet points does the York Millennium / Series 40 Packaged Rooftop Units 25-40 Ton with IPU Control have?
This list has 146 BACnet objects: 38 analog inputs, 61 analog values, 47 binary inputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which York Millennium / Series 40 Packaged Rooftop Units 25-40 Ton with IPU Control BACnet points are writable?
61 of the 146 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 York Millennium / Series 40 Packaged Rooftop Units 25-40 Ton with IPU Control BACnet documentation?
The source is Millenium Packaged Rooftop Units 25-40 Tons with IPU Control - Installation, Operation and Maintenance (Table 6-12, BACnet MS/TP, Modbus, BACnet IP) (Form 100.50-NOM8 (409)), revision 2009-04, published free by York at https://docs.johnsoncontrols.com/ductedsystems/api/khub/documents/jHl7DLBfzBwL8EpKbeMhag/content.
What are the minimum BACnet points to integrate the York Millennium / Series 40 Packaged Rooftop Units 25-40 Ton with IPU Control?
Start with AV 88 OCCUPNCY_CMD (Occupancy command (1 = occupied)); AV 93 UNIT_STOP (Unit stop (1 = stopped, 0 = normal)); AV 21 OCC_ZN_COOL (Occupied zone cooling setpoint); AV 22 OCC_ZN_HEAT (Occupied zone heating setpoint); AI 58 UNIT_MODE (Unit mode index); BI 59 SUPPLY_FAN (Supply fan on/off); AI 46 SUP_AIR_TEMP (Supply air temperature); AI 60 ZONE_TEMP (Zone temperature); BI 2 COL_HEAT_FLT (Cooling/heating fault (1 = faulted)); BI 54 SEN_MSC_FLT (Sensor/misc fault (1 = fault)).
How do I enable BMS control of the York Millennium / Series 40 Packaged Rooftop Units 25-40 Ton with IPU Control?
OCCUPNCY_CMD (AV 88) sets occupied/unoccupied from the BAS and UNIT_STOP (AV 93) shuts the unit down (0 = normal, 1 = stopped). OCC_MODE (BI 35) shows the resulting occupancy.
Can the BMS supply sensor values to the York Millennium / Series 40 Packaged Rooftop Units 25-40 Ton with IPU Control?
ZONE_TMP_BAS (AV 40) takes the zone temperature from the BAS when the control method is set to Comm Zone Temp. CO2 inside (AV 43), under-floor temperature and humidity (AV 36/37) and the duct static and supply air resets (AV 5, AV 28) are also BAS inputs; several must be enabled with the Service key first.
How do I check these points on the real Millennium / Series 40 Packaged Rooftop Units 25-40 Ton with IPU Control?
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.
