York YVWA Water-Cooled Variable-Speed Screw Chiller (SC-EQ) BACnet points list
Updated 4 November 2026
YVWA chillers connect to a BAS through the SC-EQ communication card on BACnet MS/TP (or Modbus RTU / N2). The BAS can start/stop the unit, write the chilled liquid setpoint, current limit and heating setpoint, and switch between chiller and heat pump mode. Read-only points cover chilled and condenser liquid temperatures, per-system pressures, % FLA, hours and starts, VSD values, valve positions and multistate operational and fault codes per system.
This page lists 76 BACnet objects for the York YVWA Water-Cooled Variable-Speed Screw Chiller (SC-EQ) — 6 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 YVWA Water-Cooled Variable-Speed Screw Chiller (SC-EQ)
Put the chiller in remote control (BV 20 reads Remote), then start/stop it with BV 1 and write the chilled liquid setpoint (AV 1) and current limit (AV 2); heat pump units also take BV 3 (mode) and AV 4 (heating setpoint). Read BV 5 for chiller run, the leaving chilled liquid temperature, VSD frequency and BV 6 for the chiller alarm; the fault code MVs give the cause.
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 |
|---|---|---|---|
| BV 1 | REM START STOP CMD | Remote start/stop (1 = run) | Command |
| AV 1 | REM CHILLED LIQ SETPOINT | Remote chilled liquid setpoint | Command |
| AV 2 | REM CURRENT LIMIT SETP | Remote current limit, % | Command |
| BV 5 | CHILLER RUN | Chiller running | Read |
| BV 20 | LOCAL REMOTE CONTROL MODE | Must read Remote (1) for BMS control | Read |
| AV 5 | LEAVING CHILLED LIQ TEMP | Leaving chilled liquid temperature | Read |
| AV 27 | VSD OUTPUT FREQUENCY | Compressor VSD frequency (load indication) | Read |
| BV 6 | CHILLER ALARM | Chiller alarm active | Read |
| MV 2 | SYS 1 FAULT CODE / FAULT CODE | Fault/inhibit code, Sys 1 or unit (1 = none) | Read |
Enable & remote start
BV 20 shows Local or Remote control mode. The points list gives no point to change it and no write-enable point. On heat pump units BV 3 selects chiller or heat pump operation.
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).
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.
- The fault code table differs between one- and two-compressor units; check the compressor count before decoding MV 2.

Integration notes
- Access is inferred: the sheet has no read/write column. The remote block (AV 1, AV 2, AV 4, BV 1, BV 3, BV 4) is treated as commandable; everything else as read-only.
- System 2 points only report on two-compressor units. MV 2 / AV 502 are printed twice: Sys 1 fault code on two-compressor units and the unit fault code on one-compressor units, each with its own code table; they are merged here and both tables are given.
- Operational and fault code MVs are the printed code + 1, as the doc's status code tables say; the AV copies (AV 501-504) carry the raw code. Binary states are as printed.
- This list has no MV 65001 Units object. Units shown are the IP units.
- Spare and reserved objects 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 YVWA Water-Cooled Variable-Speed Screw Chiller (SC-EQ) 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 YVWA Water-Cooled Variable-Speed Screw Chiller (SC-EQ)
How many BACnet points does the York YVWA Water-Cooled Variable-Speed Screw Chiller (SC-EQ) have?
This list has 76 BACnet objects: 45 analog values, 27 binary values, 4 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which York YVWA Water-Cooled Variable-Speed Screw Chiller (SC-EQ) BACnet points are writable?
6 of the 76 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 YVWA Water-Cooled Variable-Speed Screw Chiller (SC-EQ) BACnet documentation?
The source is YVWA SC-EQ BAS Points List, revision Rev 2.1, 2019-11-05, published free by York at https://docs.johnsoncontrols.com/chillers/api/khub/documents/GBppk5iQWBiKzUyxqfeOFA/content.
What are the minimum BACnet points to integrate the York YVWA Water-Cooled Variable-Speed Screw Chiller (SC-EQ)?
Start with BV 1 REM START STOP CMD (Remote start/stop (1 = run)); AV 1 REM CHILLED LIQ SETPOINT (Remote chilled liquid setpoint); AV 2 REM CURRENT LIMIT SETP (Remote current limit, %); BV 5 CHILLER RUN (Chiller running); BV 20 LOCAL REMOTE CONTROL MODE (Must read Remote (1) for BMS control); AV 5 LEAVING CHILLED LIQ TEMP (Leaving chilled liquid temperature); AV 27 VSD OUTPUT FREQUENCY (Compressor VSD frequency (load indication)); BV 6 CHILLER ALARM (Chiller alarm active); MV 2 SYS 1 FAULT CODE / FAULT CODE (Fault/inhibit code, Sys 1 or unit (1 = none)).
How do I enable BMS control of the York YVWA Water-Cooled Variable-Speed Screw Chiller (SC-EQ)?
BV 20 shows Local or Remote control mode. The points list gives no point to change it and no write-enable point. On heat pump units BV 3 selects chiller or heat pump operation.
How do I check these points on the real YVWA Water-Cooled Variable-Speed Screw 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.
