Carrier 42WKN Chilled Water Cassette (microprocessor controller) BACnet points list
Updated 7 November 2026
The 42WKN cassette controller has a built-in RS-485 port that runs BACnet MS/TP or Modbus RTU, chosen with DIP switch SW3.8 (on = BACnet). The object list has 105 objects: sensor inputs, valve and fan outputs, setpoints, mode, fan speed, occupancy and PID/fan-speed tuning values, and binary values for on/off, keypad locks and input polarity.
This page lists 105 BACnet objects for the Carrier 42WKN Chilled Water Cassette (microprocessor controller) — 93 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Carrier’s own free documentation, linked below.

BMS integration notes: Carrier 42WKN Chilled Water Cassette (microprocessor controller)
Set SW3.8 on (BACnet MS/TP), give each cassette a unique address 0-63 on SW1, and the device instance becomes 315000 plus that address. From the BMS, turn the unit on/off with BV 0, write the mode (AV 4), fan speed (AV 6) and cooling/heating setpoints, and read the effective mode, fan, setpoint and return air temperature.
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.
| Object | Name | Why | Access |
|---|---|---|---|
| BV 0 | OnOff | Unit on/off command (1=On) | Write |
| AV 4 | Mode | Mode: 0=Fan only, 1=Cool, 2=Heat, 3=Auto | Write |

| AV 7 | FanEffective | Effective fan speed | Read |
| AV 3 | ReturnAirSensorEffective | Return air temperature in use | Read |
| BI 0 | DI_1 | Alarm relay input: 1 = fault, outputs off | Read |
Enable & remote start
No separate enable; the BMS writes On/Off (BV 0), mode and setpoints directly. Keypad lock BVs (BV 3-6) stop local changes at the touchscreen thermostat.
Network setup
- SW3.8 on = BACnet MS/TP (default), off = Modbus.
- MAC address 0-63 is set on DIP switches SW1.1-SW1.6.
- MS/TP baud rate 9600, 19200, 38400 or 76800; no parity, 8 data bits, 1 stop bit.
- Device instance = 315000 + MAC address.
Watch out for
- BV 13 RestoreDefault resets the controller to factory settings; do not write it.
- Mode, fan speed and occupancy are analog values with numeric codes, not multistate objects.

Integration notes
- Objects are printed as 'Analog Value #0' style references; the number after # is the object instance.
- Mode, fan speed and occupancy points are analog values whose numeric codes are given in the Value column (e.g. 0-Fan only, 1-Cool, 2-Heat, 3-Auto); those codes are kept in the states field.
- For analog objects the printed range is kept in the description; temperatures are shown in °F with °C in brackets.
- AV 113 ModbusBaudRate is marked not in use.
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 42WKN Chilled Water Cassette (microprocessor controller) and exports what it actually has to Excel — free.

Questions about the Carrier 42WKN Chilled Water Cassette (microprocessor controller)
How many BACnet points does the Carrier 42WKN Chilled Water Cassette (microprocessor controller) have?
This list has 105 BACnet objects: 3 analog inputs, 3 analog outputs, 64 analog values, 4 binary inputs, 9 binary outputs, 22 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Carrier 42WKN Chilled Water Cassette (microprocessor controller) BACnet points are writable?
93 of the 105 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 Carrier 42WKN Chilled Water Cassette (microprocessor controller) BACnet documentation?
The source is Microprocessor Controls Manual for Chilled Water Cassettes, Models 42WKN - Controls Operation and Troubleshooting (Table 21, BACnet Points List) (42WKN-1T), revision 2026-10, published free by Carrier at https://brandportal.carrier.com/asset/113fdae2-3fa6-4fd8-8f2f-52d362b2df24/42WKN-1T.pdf.
What are the minimum BACnet points to integrate the Carrier 42WKN Chilled Water Cassette (microprocessor controller)?
Start with BV 0 OnOff (Unit on/off command (1=On)); AV 4 Mode (Mode: 0=Fan only, 1=Cool, 2=Heat, 3=Auto); AV 6 FanSpeed (Fan speed: 0=Auto, 1=Low, 2=Medium, 3=High); AV 0 SetPoint_SetPointCool (Cooling setpoint); AV 1 SetPointHeat (Heating setpoint); BV 16 UnoccupiedByNetwork (Network unoccupied command (1=Unoccupied)); AV 5 ModeEffective (Effective mode (4=Off)); AV 7 FanEffective (Effective fan speed); AV 3 ReturnAirSensorEffective (Return air temperature in use); BI 0 DI_1 (Alarm relay input: 1 = fault, outputs off).
How do I enable BMS control of the Carrier 42WKN Chilled Water Cassette (microprocessor controller)?
No separate enable; the BMS writes On/Off (BV 0), mode and setpoints directly. Keypad lock BVs (BV 3-6) stop local changes at the touchscreen thermostat.
How do I check these points on the real 42WKN Chilled Water Cassette (microprocessor controller)?
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.
