York Roomtop RTC/RTH-L with YKN2Open BMS kit (BACnet IP) BACnet points list
Updated 4 November 2026
These European York packaged units use the YKN2Open control, which speaks JCI Metasys N2 on RS-485. The S606791244 BMS kit adds a FieldServer QuickServer that converts N2 to BACnet IP (a sister kit, S606791245, does Modbus TCP). One QuickServer serves up to five units, each shown as its own virtual BACnet device with temperatures, enthalpies, run hours, an error code, setpoints, mode, fan mode, on/off and override/release flags.
This page lists 50 BACnet objects for the York Roomtop RTC/RTH-L with YKN2Open BMS kit (BACnet IP) — 18 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 Roomtop RTC/RTH-L with YKN2Open BMS kit (BACnet IP)
Wire the YKN2Open boards on an RS-485 N2 bus to the QuickServer, give each board an N2 address (1-5) with the YKTool, then read each unit as virtual device 11-15. Write ON/OFF, Mode, the occupied setpoints and fan mode, and read temperatures, Error Code and Status.
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.

|---|---|---|---|

| AV 3 | Setpoint occupied heat | Occupied heating setpoint, 10-32 °C | Write |
| BV 1 | Fan Mode | 0 = fan auto, 1 = continuous | Write |
| AI 16 | Indoor Temperature | Room temperature | Read |

| BV 3 | Status | Gateway comms with this unit (Online/Offline) | Read |
Enable & remote start
Once the gateway is communicating, any analog or digital command written from the BMS takes over that function: it can no longer be changed from the thermostat or YKTool. ON/OFF (BV 2) is the run command; holding it at 0 keeps the unit off.
Heartbeat & communication loss
No heartbeat point is described. If N2 communication to a unit is lost, Status (BV 3) goes Offline and the other objects keep their last values.
Network setup
- Kit S606791244 = FieldServer QuickServer FS-QS-1010-0122 (BACnet IP to Metasys N2); S606791245 is the Modbus TCP version.
- Up to 5 units per QuickServer on RS-485 (Belden 9272 or equal, max 1000 m), wired to J12 terminals 1-2 on each YKN2Open board; 150 ohm resistor on the last board.
- N2 link: 9600 baud, 8 data bits, no parity, 1 stop bit; set each board's N2 address (1-5) in YKTool menu 7 > Configuration.
- Set the QuickServer IP address with the FieldServer Toolbox application.
- Virtual BACnet device IDs 11-15 match N2 addresses 1-5.
Watch out for
- To reset an alarm write ON/OFF to 0 and back to 1 after 5 seconds, once the cause has cleared; leaving it at 0 keeps the unit off.
- After the BMS writes a setpoint or command, local changes from the thermostat or YKTool for that variable are locked out.
- Values are metric (°C).
- Poll only the variables the unit actually has, to avoid slow N2 updates.

Integration notes
- The doc has no read/write column, so access is inferred. AV objects are marked In/Out (shown W); Fan Mode and ON/OFF are the unit's writable digital outputs; the Override and Release BVs are also shown W, but the doc doesn't say how they are used.
- Each unit appears as a separate virtual BACnet device (Virtual_Dev_11 to _15, device IDs 11-15) behind the QuickServer; the object list is the same on each.
- Status (BV 3) on each virtual device reads Online when the gateway is talking to that unit; other values hold their last reading when communication is lost.
- Error Code (AI 31) gives alarm numbers 11-46 for the YKN2Open board and 91-99 for thermostat/probe faults.
- Only map the points that exist on the unit's configuration and accessories; the doc warns extra variables slow the N2 polling.
- Names are printed as in the doc, including spelling (Suply, Outdor, Water Bomb = water pump).
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 Roomtop RTC/RTH-L with YKN2Open BMS kit (BACnet IP) and exports what it actually has to Excel — free.

Questions about the York Roomtop RTC/RTH-L with YKN2Open BMS kit (BACnet IP)
How many BACnet points does the York Roomtop RTC/RTH-L with YKN2Open BMS kit (BACnet IP) have?
This list has 50 BACnet objects: 31 analog inputs, 4 analog values, 15 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which York Roomtop RTC/RTH-L with YKN2Open BMS kit (BACnet IP) BACnet points are writable?
18 of the 50 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 Roomtop RTC/RTH-L with YKN2Open BMS kit (BACnet IP) BACnet documentation?
The source is YKN2Open BMS BACnet/IP and Modbus TCP/IP - Installation and user manual (N-40462_EN 0716), published free by York at https://docs.johnsoncontrols.com/bas/api/khub/documents/bdk7s53yQ5tftUD6MrJq9g/content.
What are the minimum BACnet points to integrate the York Roomtop RTC/RTH-L with YKN2Open BMS kit (BACnet IP)?
Start with BV 2 ON/OFF (Unit on (1) / forced off (0)); AV 8 Mode (0=Off, 1=Cool, 2=Heat, 3=Auto, 5=Emerg Heat); AV 2 Setpoint occupied cool (Occupied cooling setpoint, 10-32 °C); AV 3 Setpoint occupied heat (Occupied heating setpoint, 10-32 °C); BV 1 Fan Mode (0 = fan auto, 1 = continuous); AI 16 Indoor Temperature (Room temperature); AI 12 Suply air Temperature (Supply air temperature); AI 31 Error Code (Active alarm number, see alarm table); BV 3 Status (Gateway comms with this unit (Online/Offline)).
How do I enable BMS control of the York Roomtop RTC/RTH-L with YKN2Open BMS kit (BACnet IP)?
Once the gateway is communicating, any analog or digital command written from the BMS takes over that function: it can no longer be changed from the thermostat or YKTool. ON/OFF (BV 2) is the run command; holding it at 0 keeps the unit off.
Does the York Roomtop RTC/RTH-L with YKN2Open BMS kit (BACnet IP) need a BACnet heartbeat or have a communication timeout?
No heartbeat point is described. If N2 communication to a unit is lost, Status (BV 3) goes Offline and the other objects keep their last values.
How do I check these points on the real Roomtop RTC/RTH-L with YKN2Open BMS kit (BACnet IP)?
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.
