Thermokon WRF04 BACnet MS/TP RS485 room operating unit BACnet points list

Updated 6 November 2026

Short answer

WRF04 is a wall-mounted room unit with BACnet MS/TP. The interface description lists 26 objects including the device object: room temperature, setpoint potentiometer, button, digital inputs and rotary switch, two 0-10 V outputs, offsets, setpoint scaling and LED behaviour.

This page lists 25 BACnet objects for the Thermokon WRF04 BACnet MS/TP RS485 room operating unit — 19 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Thermokon’s own free documentation, linked below.

BMS integration notes: Thermokon WRF04 BACnet MS/TP RS485 room operating unit

Integration in brief

Read the temperature, the setpoint potentiometer and the button/digital inputs; the BMS can drive the two 0-10 V outputs and the LED.

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.

Thermokon WRF04 BACnet MS/TP RS485 room operating unit BACnet objects

Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.

Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.

Integration notes

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 WRF04 BACnet MS/TP RS485 room operating unit and exports what it actually has to Excel — free.

Questions about the Thermokon WRF04 BACnet MS/TP RS485 room operating unit

How many BACnet points does the Thermokon WRF04 BACnet MS/TP RS485 room operating unit have?

This list has 25 BACnet objects: 2 analog inputs, 2 analog outputs, 10 analog values, 3 binary inputs, 7 binary values, 1 multi-state input. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Thermokon WRF04 BACnet MS/TP RS485 room operating unit BACnet points are writable?

19 of the 25 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 Thermokon WRF04 BACnet MS/TP RS485 room operating unit BACnet documentation?

The source is Interface Description WRF04/FTW04 BACnet MS/TP, revision Rev. A, 17.05.2013, published free by Thermokon at https://www.thermokon.de/downloads/Software/Schnittstellenbeschreibung/BACnet/WRF04_FTW04-RS485_BACnet_InterfaceDescription.zip.

What are the minimum BACnet points to integrate the Thermokon WRF04 BACnet MS/TP RS485 room operating unit?

Start with AI 0 Temperature (Room temperature); AI 1 Set point (Setpoint potentiometer value); BI 0 Button (Button state); MI 0 RotarySwitch (Rotary switch position 1-5).

How do I check these points on the real WRF04 BACnet MS/TP RS485 room operating unit?

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.
