York L-Series LSWU / LSWD / LSWF Water-Cooled Self-Contained Unit, 25-105 ton (IPU2, native BACnet MS/TP) BACnet points list
Updated 6 November 2026
The IPU2 controller of the L-Series water-cooled self-contained units speaks BACnet MS/TP on Port 1 (Modbus is also offered). The table lists about 170 objects: air and condenser water temperatures, refrigerant pressures, compressor and heat stage status, condenser water and waterside economizer valves, duct static and supply fan VFD values, setpoints and limits, BAS inputs, and BAS commands for occupancy, unit stop, morning warm-up, ventilation and heating.
This page lists 167 BACnet objects for the York L-Series LSWU / LSWD / LSWF Water-Cooled Self-Contained Unit, 25-105 ton (IPU2, native BACnet MS/TP) — 57 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 L-Series LSWU / LSWD / LSWF Water-Cooled Self-Contained Unit, 25-105 ton (IPU2, native BACnet MS/TP)
Connect to Port 1 of the IPU2 control board on BACnet MS/TP. Command occupancy with OCCUPNCY_CMD (BV 12), stop or release the unit with UNIT_STOP (BV 17) and write the occupied zone setpoints; read supply air, zone and condenser water temperatures, supply fan status, unit mode and the alarm input.
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
OCCUPNCY_CMD (BV 12) puts the unit in occupied (1) or unoccupied (0) mode and UNIT_STOP (BV 17) stops it (1) or returns it to normal operation (0). SYSTEM_STOP (AV 35) can turn off individual compressor systems.
Sensors & values from the BMS
ZONE_TMP_BAS (AV 40) lets the BAS supply zone temperature on a constant volume unit; OAT_CURR_BAS (AV 49) and OA_RH_BAS (AV 50) supply outdoor temperature and humidity when the airside economizer is selected; UND_TEMP_BAS / UND_HUMD_BAS (AV 37/36) feed under-floor values on FlexSys units.
Network setup
- BACnet MS/TP must use Port 1 of the IPU2 board; Port 2 is the RS-232 terminal port.
- Set the MAC address (1-127) with the SW2 DIP switches (switch 8 always ON) or the SERVICE key; the default device instance is 23000 plus the MAC address.
- A different device instance is set with DE MODIFIER ADDRESS x 100 + DE MODIFIER OFFSET; to keep the automatic instance, DE MODIFIER OFFSET must be -1.
- Cycle unit power after changing the MAC address or the port settings.
Watch out for
- Setpoints, limits and enable values are setup values; don't write them cyclically.
- Many points only exist on FlexSys, VAV or constant volume units, or with options such as the waterside economizer.

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.
- The table prints ACT_SLAB_CTL (Modbus 1102) as AI 5 and COMFORT_VENT (Modbus 1103) as AI 2, the same IDs as the pressure points AV_PRS_A_SUC and AV_PRS_DIS; those two writable on/off rows are left out because their real object IDs cannot be told from the doc.
- The economizer method selector appears twice as AV 6 (ECONO_METHOD and ECON_METHOD); it is listed once. Ten on/off settings and commands (ECONO_INSTAL, FLSYS_REHEAT, HEAT_ENABLE, HEAT_VACTION, MORN_WARM_UP, MORN_WUP_CMD, NIGHT_SETBAC, OCCUPNCY_CMD, UNIT_STOP, VENT_ENABLE) are printed with both a BV and an AV ID (AV 81-95); they are listed by the BV ID.
- Multistate status codes (unit mode, system status, compressor status) are published as AIs; the code lists are in the table description column and are not repeated here.
- Units are taken from the description column where it states them. The Modbus register addresses in the same table are not reproduced.
- The older Versecon YSWU/YSWD IPU (IPU1) IOM 145.05-NOM3 prints a largely overlapping list.
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 L-Series LSWU / LSWD / LSWF Water-Cooled Self-Contained Unit, 25-105 ton (IPU2, native BACnet MS/TP) and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.
Questions about the York L-Series LSWU / LSWD / LSWF Water-Cooled Self-Contained Unit, 25-105 ton (IPU2, native BACnet MS/TP)
How many BACnet points does the York L-Series LSWU / LSWD / LSWF Water-Cooled Self-Contained Unit, 25-105 ton (IPU2, native BACnet MS/TP) have?
This list has 167 BACnet objects: 70 analog inputs, 45 analog values, 41 binary inputs, 11 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which York L-Series LSWU / LSWD / LSWF Water-Cooled Self-Contained Unit, 25-105 ton (IPU2, native BACnet MS/TP) BACnet points are writable?
57 of the 167 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.

What are the minimum BACnet points to integrate the York L-Series LSWU / LSWD / LSWF Water-Cooled Self-Contained Unit, 25-105 ton (IPU2, native BACnet MS/TP)?
Start with BV 12 OCCUPNCY_CMD (Occupancy command (1 = occupied)); BV 17 UNIT_STOP (Unit stop (1 = stopped, 0 = normal)); AV 21 OCC_ZN_COOL (Occupied zone cooling setpoint, °F); AV 22 OCC_ZN_HEAT (Occupied zone heating setpoint, °F); AI 58 UNIT_MODE (Current operating mode index); BI 59 SUPPLY_FAN (Supply fan on/off); AI 46 SUP_AIR_TEMP (Supply air temperature, °F); AI 60 ZONE_TEMP (Zone temperature, °F); AI 90 WTR_TEMP_ENT (Entering condenser water temperature); BI 2 ALARM (Unit alarm (FLT = faulted)).
How do I enable BMS control of the York L-Series LSWU / LSWD / LSWF Water-Cooled Self-Contained Unit, 25-105 ton (IPU2, native BACnet MS/TP)?
OCCUPNCY_CMD (BV 12) puts the unit in occupied (1) or unoccupied (0) mode and UNIT_STOP (BV 17) stops it (1) or returns it to normal operation (0). SYSTEM_STOP (AV 35) can turn off individual compressor systems.
Can the BMS supply sensor values to the York L-Series LSWU / LSWD / LSWF Water-Cooled Self-Contained Unit, 25-105 ton (IPU2, native BACnet MS/TP)?
ZONE_TMP_BAS (AV 40) lets the BAS supply zone temperature on a constant volume unit; OAT_CURR_BAS (AV 49) and OA_RH_BAS (AV 50) supply outdoor temperature and humidity when the airside economizer is selected; UND_TEMP_BAS / UND_HUMD_BAS (AV 37/36) feed under-floor values on FlexSys units.
How do I check these points on the real L-Series LSWU / LSWD / LSWF Water-Cooled Self-Contained Unit, 25-105 ton (IPU2, native 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.
