York YVAM Air-Cooled Magnetic-Bearing Centrifugal Chiller (SC-EQ) BACnet points list
Updated 4 November 2026
The YVAM's SC-EQ card puts the chiller on a BACnet MS/TP trunk (it also speaks Modbus RTU and N2). The BAS can run/stop the chiller and write the leaving chilled liquid setpoint and input current limit. Read-only points cover chilled liquid and ambient temperatures, refrigerant pressures, compressor VSD values and harmonics, magnetic bearing (MBC) status, condenser fan VSD speeds and faults, and operation, fault, warning and inhibit codes as MV objects with AV copies.
This page lists 109 BACnet objects for the York YVAM Air-Cooled Magnetic-Bearing Centrifugal Chiller (SC-EQ) — 4 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 YVAM Air-Cooled Magnetic-Bearing Centrifugal Chiller (SC-EQ)
Wire the BAS to the SC-EQ J12 RS-485 port and set the MAC address; the card detects BACnet MS/TP. Run/stop the chiller with BV 1 and write the leaving chilled liquid setpoint (AV 1) and input current limit (AV 2). Read MV 1, BV 5, the leaving water temperature and % FLA, and MV 2/MV 3 for shutdowns. MV 5 shows whether the chiller is under ISN (BAS) control.
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 1 | REM LEAVING CHL TEMP SP | Remote leaving chilled liquid setpoint | Command |

| BV 5 | COMPR MOTOR STATUS | Compressor motor running | Read |
| MV 5 | UNIT CONTROL SOURCE | Control source; ISN (BAS) for BMS control | Read |
| AV 5 | LEAVING CH LIQ TEMP | Leaving chilled liquid temperature | Read |
| AV 24 | INPUT CURRENT PCT FLA | Input current, % FLA (load indication) | Read |

| MV 3 | UNIT CYCLING FAULT CODE | Cycling shutdown code (1 = none) | Read |
Enable & remote start
BV 1 REM RUN STOP CMD (0 = Stop, 1 = Run) is the BAS run/stop and AV 1-2 the remote setpoints. MV 5 shows the control source (Local, ISN (BAS), Analog, Digital, Modem, Remote); it should read ISN for BAS control. The points list has no write-enable point.
Network setup
- The BAS connects to the SC-EQ J12 port (RS-485: +, -, COM/REF, SHLD). The card detects BACnet MS/TP, Modbus RTU or N2 and the baud rate by itself; allow up to 120 seconds after power-up.
- The MAC address (1-127) is set on DIP switch SW1 (switch 8 unused). Cycle the card's power after changing it.
- The device instance defaults to 5000 + the MAC address (MAC 6 gives 5006). To use another number, set Device Instance Mode to Manual and enter the instance with the SC-AP / MAP tool, or write BV 65000 (mode) and AV 65000 (instance ID).
- MV 65001 Units sets whether the BAS sees IP or SI values, independent of the chiller display; set it to match the chiller.
Watch out for
- The remote (commandable) setpoints read as unreliable until the BAS writes them the first time.
- The SC-EQ only exposes the points that apply to the chiller it detects; if it replaces an E-Link, re-discover the device so old non-applicable points don't sit offline.
- Code points come in pairs: the MV state is the code + 1, and the AV copy (AV 401-408) carries the raw code.

Integration notes
- Access is inferred: the sheet has no read/write column. The remote block (AV 1-2, BV 1) is treated as commandable and MV 65001 as writable; everything else as read-only.
- Status-code MVs (MV 1-4, MV 6-8) are the printed code + 1, as the doc's status code tables say; the AV copies (AV 401-408) carry the raw code. MV 5 and MV 65001 are shown as printed, from 0; the card may report the printed number + 1. Confirm by discovery.
- Input kWh and operating hours are also split into low/offset AVs (AV 121-124): total = offset x 10,000 + low.
- Units shown are the IP units; with MV 65001 set to SI the card reports °C, kPa and so on.
- Spare objects and empty rows are left out.
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 YVAM Air-Cooled Magnetic-Bearing Centrifugal Chiller (SC-EQ) and exports what it actually has to Excel — free.

Questions about the York YVAM Air-Cooled Magnetic-Bearing Centrifugal Chiller (SC-EQ)
How many BACnet points does the York YVAM Air-Cooled Magnetic-Bearing Centrifugal Chiller (SC-EQ) have?
This list has 109 BACnet objects: 85 analog values, 15 binary values, 9 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which York YVAM Air-Cooled Magnetic-Bearing Centrifugal Chiller (SC-EQ) BACnet points are writable?
4 of the 109 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. The source has no read/write column, so this is inferred from object type.
Where is the official York YVAM Air-Cooled Magnetic-Bearing Centrifugal Chiller (SC-EQ) BACnet documentation?
The source is YVAM SC-EQ BAS Points List, revision Rev 1.5, 2022-09-20, published free by York at https://docs.johnsoncontrols.com/chillers/api/khub/documents/QO052Dm251t6v1FTiH8_iQ/content.
What are the minimum BACnet points to integrate the York YVAM Air-Cooled Magnetic-Bearing Centrifugal Chiller (SC-EQ)?
Start with BV 1 REM RUN STOP CMD (Remote run/stop (1 = run)); AV 1 REM LEAVING CHL TEMP SP (Remote leaving chilled liquid setpoint); AV 2 REMOTE INPUT CURRENT SP (Remote input current limit, %); MV 1 UNIT OPERATION CODE (Operating state (stopped, starting, running)); BV 5 COMPR MOTOR STATUS (Compressor motor running); MV 5 UNIT CONTROL SOURCE (Control source; ISN (BAS) for BMS control); AV 5 LEAVING CH LIQ TEMP (Leaving chilled liquid temperature); AV 24 INPUT CURRENT PCT FLA (Input current, % FLA (load indication)); MV 2 UNIT SAFETY FAULT CODE (Safety shutdown code (1 = none)); MV 3 UNIT CYCLING FAULT CODE (Cycling shutdown code (1 = none)).
How do I enable BMS control of the York YVAM Air-Cooled Magnetic-Bearing Centrifugal Chiller (SC-EQ)?
BV 1 REM RUN STOP CMD (0 = Stop, 1 = Run) is the BAS run/stop and AV 1-2 the remote setpoints. MV 5 shows the control source (Local, ISN (BAS), Analog, Digital, Modem, Remote); it should read ISN for BAS control. The points list has no write-enable point.
How do I check these points on the real YVAM Air-Cooled Magnetic-Bearing Centrifugal Chiller (SC-EQ)?
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.
