York YSAA Air-Cooled Screw Chiller - BAS (ISN) E-Link (YorkTalk 2) BACnet points list
Updated 6 November 2026
The E-Link gateway reads the YSAA board over YorkTalk 2 (4800 baud) and serves BACnet, N2, LON and Modbus objects named by YorkTalk page: remote setpoint and start/stop, chilled liquid and per-system refrigerant temperatures and pressures, run hours and timers, and status codes.
This page lists 67 BACnet objects for the York YSAA Air-Cooled Screw Chiller - BAS (ISN) E-Link (YorkTalk 2) — 3 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 YSAA Air-Cooled Screw Chiller - BAS (ISN) E-Link (YorkTalk 2)
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 2 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
- Points marked optional (O) on the sheet report only on units with that option or program version.

Integration notes
- This is a YorkTalk 2 E-Link sheet; objects are named by YorkTalk page (YT2_S01_P03 and so on), and only populated slots not marked unavailable on every version are listed.
- 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.
- Multistate states are shown as printed (from 0); this sheet does not say whether the BACnet value adds 1, so confirm by discovery (read the state text).
- Some slots carry a second meaning for other unit types (for example SP units); only the meaning available on this sheet's versions is kept.
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 YSAA Air-Cooled Screw Chiller - BAS (ISN) E-Link (YorkTalk 2) and exports what it actually has to Excel — free.

Questions about the York YSAA Air-Cooled Screw Chiller - BAS (ISN) E-Link (YorkTalk 2)
How many BACnet points does the York YSAA Air-Cooled Screw Chiller - BAS (ISN) E-Link (YorkTalk 2) have?
This list has 67 BACnet objects: 33 analog values, 28 binary values, 6 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which York YSAA Air-Cooled Screw Chiller - BAS (ISN) E-Link (YorkTalk 2) BACnet points are writable?
3 of the 67 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 YSAA Air-Cooled Screw Chiller - BAS (ISN) E-Link (YorkTalk 2) BACnet documentation?
The source is YSAA BAS (ISN) E-Link points list, revision 2018-01-12, published free by York at https://docs.johnsoncontrols.com/chillers/api/khub/documents/xvSi0e3Kwnf7B~5daaWaOw/content.
What are the minimum BACnet points to integrate the York YSAA Air-Cooled Screw Chiller - BAS (ISN) E-Link (YorkTalk 2)?
Start with BV 1 YT2_S01_P07 (Remote start/stop (1 = run)); AV 1 YT2_S01_P03 (Remote leaving chilled liquid setpoint); BV 21 YT2_S01_P52 (Must read Remote (1) for BMS control); MV 1 YT2_S01_P56 (System 1 operating code); AV 5 YT2_S01_P11 (Leaving chilled liquid temperature); AV 6 YT2_S01_P12 (Entering chilled liquid temperature); MV 2 YT2_S01_P57 (System 1 fault code); BV 5 YT2_S01_P36 (System 1 alarm (1 = alarm)).
How do I enable BMS control of the York YSAA Air-Cooled Screw Chiller - BAS (ISN) E-Link (YorkTalk 2)?
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 YSAA Air-Cooled Screw Chiller - BAS (ISN) E-Link (YorkTalk 2)?
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.
