York YR Screw Chiller (OptiView, SC-EQ) BACnet points list
Updated 4 November 2026
YR screw chillers with OptiView controls reach a BAS through the SC-EQ communication card on BACnet MS/TP (or Modbus RTU / N2). The BAS can run/stop the chiller and write the leaving chilled liquid setpoint and motor current limit. Read-only points cover water temperatures, refrigerant and oil pressures, slide valve position, solid-state starter values, and multistate operation, safety, cycling and warning codes.
This page lists 43 BACnet objects for the York YR Screw Chiller (OptiView, 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 YR Screw Chiller (OptiView, 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 motor current limit (AV 2). Read MV 1, BV 5, the leaving water temperature and % FLA, and MV 2/MV 3 for shutdowns.
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.

| 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, Analog, Digital, Modem); 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.

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.
- Starter values (AV 13-18) only report with a solid-state starter (SSS).
- The doc notes that AV 25's label is off: the value is the refrigerant level position.
- Status-code MVs (MV 1-4) are the printed code + 1, as the doc's status code tables say. MV 5 and MV 65001 are shown as printed, from 0; BACnet multistate values start at 1, so the card may report the printed number + 1. Confirm by discovery.
- 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 YR Screw Chiller (OptiView, SC-EQ) and exports what it actually has to Excel — free. New to BACnet?

Questions about the York YR Screw Chiller (OptiView, SC-EQ)
How many BACnet points does the York YR Screw Chiller (OptiView, SC-EQ) have?
This list has 43 BACnet objects: 29 analog values, 8 binary values, 6 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which York YR Screw Chiller (OptiView, SC-EQ) BACnet points are writable?
4 of the 43 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 YR Screw Chiller (OptiView, SC-EQ) BACnet documentation?
The source is YR (OptiView) SC-EQ BAS Points List, revision Rev 1.2, 2021-12-15, published free by York at https://docs.johnsoncontrols.com/chillers/api/khub/documents/ISru5gO~hseNJRaG8uHiHg/content.
What are the minimum BACnet points to integrate the York YR Screw Chiller (OptiView, 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 MOTOR CURRENT REMOTE SP (Remote motor 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 12 MOTOR CURRENT PCT FLA (Motor 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 YR Screw Chiller (OptiView, 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, Analog, Digital, Modem); it should read ISN for BAS control. The points list has no write-enable point.
How do I check these points on the real YR Screw Chiller (OptiView, 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.
