TROX TITAN FCU403 fan coil controller (config FCU403 TRX) BACnet points list
Updated 6 November 2026
This BACnet MS/TP technical reference, hosted by TROX, covers the Titan Products FCU4 fan coil controller with firmware 4.9 and the TROX configuration FCU403 TRX. It lists 138 objects: thermistor and universal inputs, 0-10 V and triac outputs, setpoint, deadband and PID settings, fan, occupancy and flush functions, and group master/slave objects.
This page lists 138 BACnet objects for the TROX TITAN FCU403 fan coil controller (config FCU403 TRX) — 114 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from TROX’s own free documentation, linked below.

BMS integration notes: TROX TITAN FCU403 fan coil controller (config FCU403 TRX)
Set the device instance, MAC address and baud rate on the RDU first. Then write AV 300 Set Point and MV 605 User Fan, write AV 700 Ext Temp if the BMS supplies the outdoor temperature, and read MV 602 Active Mode, AI 700 RDU Temp, the valve positions and BV 603 Fan Alarm.
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 |
|---|---|---|---|
| MV 602 | Active Mode | Operating mode (Off, Normal, Eco1, Eco2, Occ OR...) | Write |
| MV 618 | Heat Cool Cycle | Heat, Off or Cool under manual control | Write |
| MV 605 | User Fan | Fan setting: Auto or speed 0-10 | Write |
| AV 300 | Set Point | Control setpoint, °C | Write |
| AI 700 | RDU Temp | Room display unit temperature | Read |
| MV 603 | Active Fan | Current fan setting | Read |
| AV 222 | Heating % | Heating valve position (TPC/PWM only) | Read |
| AV 232 | Cooling % | Cooling valve position (TPC/PWM only) | Read |
| BV 603 | Fan Alarm | Fan proving alarm | Read |
Enable & remote start
MV 602 Active Mode is writable depending on BV 600 Off Selector (off signal from the RDU or a digital input). MV 600 Off Mode sets what runs while the unit is Off.
Sensors & values from the BMS
AV 700 Ext Temp takes an external temperature written over BACnet or from an analog input. Inputs (AI/BI) can be overridden only by setting Out_Of_Service True first.
Network setup
- Device instance, MAC address (1-127) and baud rate (9600, 19200, 38400, 76800) are set on the RDU or programming tool by pressing all four buttons together.
- With the default Device Object ID 0000000 the unit works on the local MS/TP network but does not send I-Am; enter a valid ID (1-4194302).
- Group operation: one Group_Master sends setpoint, fan, occupancy and input values to Group_Slaves with the same group number (MSV 1000/1001).
Watch out for
- Write BV 0 Flash Store only when you want current values kept after a reboot.
- User Fan (MV 605) states depend on MSV 609 Fan Speeds and BV 602 Auto Fan Enable.
- In a group, slaves use the grouped input only when their local input is out of service.

Integration notes
- The controller is made by Titan Products Ltd (PICS vendor name); TROX hosts this document for its FCU403 TRX configuration.
- Objects marked *1 in the document only exist with certain configurations; AV 220/221/222 and 230/231/232 change name with the valve type (TPC or PWM, heat, cool or combined).
- Inputs (AI/BI) are writable only when Out_Of_Service is True, so they are listed as read-only here.
- Outputs (AO/BO/MO) can be written above the controller priority 15 and are listed as commandable.
- AV 608 is named "Offset Cool" in the function table and "Offset Heat" in the range table; the function-table name is used.
- Analog input units and ranges depend on the input profile chosen in the engineer menu, so none are given.
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 TITAN FCU403 fan coil controller (config FCU403 TRX) 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 TROX TITAN FCU403 fan coil controller (config FCU403 TRX)
How many BACnet points does the TROX TITAN FCU403 fan coil controller (config FCU403 TRX) have?
This list has 138 BACnet objects: 8 analog inputs, 3 analog outputs, 63 analog values, 6 binary inputs, 4 binary outputs, 22 binary values, 1 file, 1 multi-state output, 2 notification classs, 28 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which TROX TITAN FCU403 fan coil controller (config FCU403 TRX) BACnet points are writable?
114 of the 138 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 TROX TITAN FCU403 fan coil controller (config FCU403 TRX) BACnet documentation?
The source is TITAN FCU403 (Firmware v4.9, Config. FCU403 TRX) / Graphical RDU (V2) - BACnet Technical Reference, revision 2020-02, published free by TROX at https://cdn.trox.de/b0d9ce11f7cbaedf/b57cbc9c9289/BACnet-Manual--Firmware-4.9-FCU403-TRX--02-2020.pdf.
What are the minimum BACnet points to integrate the TROX TITAN FCU403 fan coil controller (config FCU403 TRX)?
Start with MV 602 Active Mode (Operating mode (Off, Normal, Eco1, Eco2, Occ OR...)); MV 618 Heat Cool Cycle (Heat, Off or Cool under manual control); MV 605 User Fan (Fan setting: Auto or speed 0-10); AV 300 Set Point (Control setpoint, °C); AI 700 RDU Temp (Room display unit temperature); MV 603 Active Fan (Current fan setting); AV 222 Heating % (Heating valve position (TPC/PWM only)); AV 232 Cooling % (Cooling valve position (TPC/PWM only)); BV 603 Fan Alarm (Fan proving alarm).
How do I enable BMS control of the TROX TITAN FCU403 fan coil controller (config FCU403 TRX)?
MV 602 Active Mode is writable depending on BV 600 Off Selector (off signal from the RDU or a digital input). MV 600 Off Mode sets what runs while the unit is Off.
Can the BMS supply sensor values to the TROX TITAN FCU403 fan coil controller (config FCU403 TRX)?
AV 700 Ext Temp takes an external temperature written over BACnet or from an analog input. Inputs (AI/BI) can be overridden only by setting Out_Of_Service True first.
How do I check these points on the real TITAN FCU403 fan coil controller (config FCU403 TRX)?
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.
