Regin RCF fan coil room controllers (RCF-230CD, RCF-230CAD, RCF-230CTD, RCF-230CTD-EC) BACnet points list
Updated 4 November 2026
The RCF is a wall-mounted fan coil controller for heating, cooling and change-over with a three-speed or EC fan. Models with a C in the name have an RS485 port that runs EXOline, Modbus or BACnet MS/TP; BACnet is selected with parameter 57. All communicating models share one object list; objects for functions a model lacks stay unused.
This page lists 48 BACnet objects for the Regin RCF fan coil room controllers (RCF-230CD, RCF-230CAD, RCF-230CTD, RCF-230CTD-EC) — 23 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Regin’s own free documentation, linked below.

BMS integration notes: Regin RCF fan coil room controllers (RCF-230CD, RCF-230CAD, RCF-230CTD, RCF-230CTD-EC)
Set parameter 57 to BACnet MS/TP, then the MAC address and device ID (parameters 58-60). Command the unit state with RegioRemoteState (MV 5), adjust the basic setpoint (AV 33) and fan mode, and read room temperature, running mode, control mode and fan speed.
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
RegioRemoteState (MV 5) forces off, economy/standby or comfort; 6 = no remote control returns control to the buttons. RegioShutDown (BV 10) forces shutdown, and RegioFireAlarmStop (BV 9) blocks the unit until it is written back to 0.
Sensors & values from the BMS
RegioRoomTempRemote (AV 15) takes the room temperature from the network when the controller is configured for remote room temperature.
Network setup
- Parameter 57 = 1 selects BACnet MS/TP (0 = automatic EXOline/Modbus).
- MAC address 0-127 (parameter 58); device ID is set as the 4 lowest digits (59) and 3 highest digits (60). Max master is parameter 61 (default 127).
- Speeds 9600, 19200, 38400 or 76800 bit/s (76800 only for BACnet).
- Once switched to BACnet, the protocol can only be switched back from the display.
Watch out for
- RegioFireAlarmStop (BV 9) keeps the unit off and locks the On/Off button until the BMS writes 0.
- RegioBlockConfig (BV 12) locks the parameter menu and can only be released over the network.
- Value objects have no priority array; the last write wins.

Integration notes
- Object list from chapter 19 of the RCF manual (rev 3.2, May 2021), pages 52-56.
- Rows printed as 'Not used in this model' (AV 7-8, AV 11, AV 17-26, BI 1, BI 4-6, BV 0, BV 5-6, BV 8, MI 0, MV 3) are left out. BV 11 is not listed at all.
- Value objects are not commandable (no priority array).
- RegioMinECFanSpeed and RegioMaxFanSpeed (AV 27-28) only apply to the RCF-230CTD-EC.
- EDE files for the BACnet objects come with the Regio tool installation.
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 RCF fan coil room controllers (RCF-230CD, RCF-230CAD, RCF-230CTD, RCF-230CTD-EC) 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 Regin RCF fan coil room controllers (RCF-230CD, RCF-230CAD, RCF-230CTD, RCF-230CTD-EC)
How many BACnet points does the Regin RCF fan coil room controllers (RCF-230CD, RCF-230CAD, RCF-230CTD, RCF-230CTD-EC) have?
This list has 48 BACnet objects: 5 analog inputs, 22 analog values, 3 binary inputs, 8 binary values, 1 loop, 3 multi-state inputs, 6 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Regin RCF fan coil room controllers (RCF-230CD, RCF-230CAD, RCF-230CTD, RCF-230CTD-EC) BACnet points are writable?
23 of the 48 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 Regin RCF fan coil room controllers (RCF-230CD, RCF-230CAD, RCF-230CTD, RCF-230CTD-EC) BACnet documentation?
The source is RCF manual, revision Rev. 3.2, May 2021, published free by Regin at https://www.regincontrols.com/globalassets/pimmediafiles/documents/rcf_manu_en.pdf.
What are the minimum BACnet points to integrate the Regin RCF fan coil room controllers (RCF-230CD, RCF-230CAD, RCF-230CTD, RCF-230CTD-EC)?
Start with MV 5 RC_Setp_X.RegioRemoteState (Unit state command: off, economy/standby or comfort); BV 10 RC_Setp_L.RegioShutDown (Force the unit into shutdown); AV 33 RC_SetpExt_R.RegioRCFSetPoint (Basic room setpoint); MV 2 RC_Setp_X.RegioFanSelect (Fan mode: off, manual speed 1-3 or auto); MI 1 RC_Actual_X.RegioUnitState (Current running mode); MI 2 RC_Actual_X.RegioControllerState (Off, heating or cooling); MI 3 RC_Actual_X.RegioFanSpeed (Current fan speed); AI 0 RC_Actual_R.RegioRoomTemp (Room temperature); AV 3 RC_Actual_R.RegioPIDSetP (Active controller setpoint).
How do I enable BMS control of the Regin RCF fan coil room controllers (RCF-230CD, RCF-230CAD, RCF-230CTD, RCF-230CTD-EC)?
RegioRemoteState (MV 5) forces off, economy/standby or comfort; 6 = no remote control returns control to the buttons. RegioShutDown (BV 10) forces shutdown, and RegioFireAlarmStop (BV 9) blocks the unit until it is written back to 0.
Can the BMS supply sensor values to the Regin RCF fan coil room controllers (RCF-230CD, RCF-230CAD, RCF-230CTD, RCF-230CTD-EC)?
RegioRoomTempRemote (AV 15) takes the room temperature from the network when the controller is configured for remote room temperature.
How do I check these points on the real RCF fan coil room controllers (RCF-230CD, RCF-230CAD, RCF-230CTD, RCF-230CTD-EC)?
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.
