York YD Dual-Compressor Centrifugal Chiller - OptiView E-Link (YorkTalk 3) BACnet points list
Updated 6 November 2026
The E-Link gateway reads the YD OptiView microboard over YorkTalk 3 and serves BACnet, N2, LON and Modbus objects: remote setpoint, current limit, compressor operation mode and lockout, run/stop, water temperatures and pressures, per-compressor oil and motor values and the status codes.
This page lists 109 BACnet objects for the York YD Dual-Compressor Centrifugal Chiller - OptiView E-Link (YorkTalk 3) — 5 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 YD Dual-Compressor Centrifugal Chiller - OptiView E-Link (YorkTalk 3)
Put the chiller in remote/ISN control at the panel, then start and stop it with the E-Link remote run/stop object and write the remote setpoint and current limit. Read the operating, safety and warning codes, run status and water temperatures.
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
The E-Link remote slots (AV 1-4, BV 1-4) are the BMS commands; the chiller panel must be set for remote (ISN/BAS) control for them to take effect.
Network setup
- The E-Link gateway talks to the chiller microboard over YorkTalk 3 and serves BACnet, N2, LON and Modbus; BACnet addressing is set on the E-Link.
- Check the chiller program version against the sheet's version table; availability codes (S/O/N) are per version.
Watch out for
- Status codes are multistate values offset by 1 from the printed code tables.
- Points marked optional (O) on the sheet report only on units with that option or program version.

Integration notes
- Every YorkTalk 3 E-Link sheet uses the same slot skeleton (P03 = AV 1 and so on); only the slots this chiller populates are listed, and slots marked not available on every program version are left out.
- Object names are the E-Link names printed on the sheet; the sheet also gives LON, N2 and Modbus addresses, not reproduced here.
- Access follows the sheet's Modbus function note: the remote slots AV 1-4 and BV 1-4 accept writes; the rest are read-only.
- Status code objects (MV) use the code tables in the sheet; it notes that BACnet multistate values are the printed code + 1. Printed states are shown from 0.
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 YD Dual-Compressor Centrifugal Chiller - OptiView E-Link (YorkTalk 3) 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 YD Dual-Compressor Centrifugal Chiller - OptiView E-Link (YorkTalk 3)
How many BACnet points does the York YD Dual-Compressor Centrifugal Chiller - OptiView E-Link (YorkTalk 3) have?
This list has 109 BACnet objects: 75 analog values, 26 binary values, 8 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which York YD Dual-Compressor Centrifugal Chiller - OptiView E-Link (YorkTalk 3) BACnet points are writable?
5 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.
Where is the official York YD Dual-Compressor Centrifugal Chiller - OptiView E-Link (YorkTalk 3) BACnet documentation?
The source is YD OptiView BAS E-Link points list, revision 2018-02-27 (Rev K_06f), published free by York at https://docs.johnsoncontrols.com/chillers/api/khub/documents/l7pWhFILYevobk9HZKrdBw/content.
What are the minimum BACnet points to integrate the York YD Dual-Compressor Centrifugal Chiller - OptiView E-Link (YorkTalk 3)?
Start with BV 1 REM RUN STOP CMD (Remote start/stop (1 = run)); AV 1 REM LEAVING CH LIQ TEMP SP (Remote leaving chilled liquid setpoint); AV 2 REM MOTOR CURRENT SP (Remote current limit, %); MV 8 UNIT CONTROL SOURCE (Must read ISN (BAS) for BMS control); MV 1 UNIT OPERATION CODE (Unit operating status code); BV 5 COMPR MOTOR STATUS 1 (Chiller running); AV 5 LEAVING CH LIQ TEMP (Leaving chilled liquid temperature); AV 6 ENTERING CH LIQ TEMP (Entering chilled liquid temperature); MV 2 UNIT SAFETY FAULT CODE (Safety (shutdown) fault code); MV 4 UNIT WARNING CODE (Active warning code).
How do I enable BMS control of the York YD Dual-Compressor Centrifugal Chiller - OptiView E-Link (YorkTalk 3)?
The E-Link remote slots (AV 1-4, BV 1-4) are the BMS commands; the chiller panel must be set for remote (ISN/BAS) control for them to take effect.
How do I check these points on the real YD Dual-Compressor Centrifugal Chiller - OptiView E-Link (YorkTalk 3)?
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.
