York Competitive Retrofit Chiller Panel (SC-EQ) BACnet points list
Updated 4 November 2026
This is the SC-EQ points list for chillers converted to Johnson Controls retrofit controls. The SC-EQ card serves BACnet MS/TP (or Modbus RTU / N2). The BAS can start/stop the chiller, write the leaving chilled liquid setpoint and current limit, and select VSD fixed speed. Read-only points cover water temperatures, pressures, starter and VSD values, adaptive capacity control (surge) data, motor winding and bearing temperatures, and operation, safety, cycling, warning and inhibit codes as MV objects with AV copies.
This page lists 80 BACnet objects for the York Competitive Retrofit Chiller Panel (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 Competitive Retrofit Chiller Panel (SC-EQ)
Wire the BAS to the SC-EQ RS-485 port and set the MAC address; the card detects BACnet MS/TP. Start/stop the chiller with BV 1 and write the leaving chilled liquid setpoint (AV 1) and 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 panel 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.

Enable & remote start
BV 1 REM START STOP CMD (0 = Stop, 1 = Start) is the BAS start/stop and AV 1-2 the remote setpoints. MV 5 shows the control source (Local, ISN (BAS), 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).
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.
- Starter type changes what AV 13-15, AV 35 and AV 36 mean; check the starter before trending them.

Integration notes
- Access is inferred: the sheet has no read/write column. The remote block (AV 1-2, BV 1, BV 3) is treated as commandable; everything else as read-only.
- Some instances depend on the starter: AV 13-15 carry VSD currents on VSD units and solid-state starter currents on SSS units; AV 35 and AV 36 carry VSD values on VSD units and solid-state or electro-mechanical starter values otherwise. AV 7 and AV 8 are printed twice, in PSIG and PSIA. These are merged into one row each.
- VSD-only points (AV 32-43, AV 110-115, BV 17-21) only report on chillers with a variable speed drive.
- 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 is shown as printed, from 0; the card may report the printed number + 1. Confirm by discovery.
- This list has no MV 65001 Units object. Units shown are the IP units.
- 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 Competitive Retrofit Chiller Panel (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 Competitive Retrofit Chiller Panel (SC-EQ)
How many BACnet points does the York Competitive Retrofit Chiller Panel (SC-EQ) have?
This list has 80 BACnet objects: 59 analog values, 13 binary values, 8 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which York Competitive Retrofit Chiller Panel (SC-EQ) BACnet points are writable?
4 of the 80 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 Competitive Retrofit Chiller Panel (SC-EQ) BACnet documentation?
The source is Competitive Retrofits SC-EQ BAS Points List, revision Rev 1.3, 2020-12-18, published free by York at https://docs.johnsoncontrols.com/chillers/api/khub/documents/BIOPM0nRZnUk75tsUSvUTA/content.
What are the minimum BACnet points to integrate the York Competitive Retrofit Chiller Panel (SC-EQ)?
Start with BV 1 REM START STOP CMD (Remote start/stop (1 = start)); AV 1 REM LEAVING CHL TEMP SP (Remote leaving chilled liquid setpoint); AV 2 REMOTE CURRENT 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 Competitive Retrofit Chiller Panel (SC-EQ)?
BV 1 REM START STOP CMD (0 = Stop, 1 = Start) is the BAS start/stop and AV 1-2 the remote setpoints. MV 5 shows the control source (Local, ISN (BAS), 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 Competitive Retrofit Chiller Panel (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.
