Regin RegioArdo two-room controller (dampers, chilled beams, radiators) BACnet points list

Updated 4 November 2026

Short answer

RegioArdo is a ceiling-void or DIN-rail room controller that can run two rooms independently, with heating, cooling, VAV, CO2, lighting, blinds and underfloor-heating functions. It talks EXOline, Modbus or BACnet MS/TP on its two RS485 ports and BACnet IP on Ethernet. The BACnet list is fixed and large because every function and both rooms have their own objects.

This page lists 455 BACnet objects for the Regin RegioArdo two-room controller (dampers, chilled beams, radiators) — 239 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 RegioArdo two-room controller (dampers, chilled beams, radiators)

Integration in brief

Select BACnet on the RS485 port (or BACnet IP on the Ethernet port) in Application tool, then command the unit state with RegioControllerStateRemote (MV 30010) and set the comfort setpoints. If the communication heartbeat is enabled, the BMS must keep writing RegioCommFailsafe (BV 10009). Read RegioControlState, RegioRoomTemp and the sum alarm for status. Room 2 has its own set of ...Zone2 objects.

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

RegioControllerStateRemote (MV 30010) forces off, unoccupied, standby or occupied; 6 = no remote control hands control back to the controller's own logic.

Heartbeat & communication loss

Optional communication heartbeat: when enabled (RegioEnableCommFailsafe, BV 10010) the BMS must set RegioCommFailsafe (BV 10009) to 1 within the failsafe time (default 10 min). If it doesn't, the controller goes to the configured failsafe state (RegioFailsafeState, MV 30182; default Off), raises an alarm and shows RegioCommFailsafeActive (BV 20099).

Sensors & values from the BMS

In the BACnet list only the underfloor temperature can come from the network: set RegioRemoteUnderfloorTempSelect (BV 10012) and write RegioRemoteUnderfloortemp (AV 30202). The BMS can also shift the setpoint with RegioSetPOffsetRemote (AV 30009).

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 RegioArdo two-room controller (dampers, chilled beams, radiators) 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 RegioArdo two-room controller (dampers, chilled beams, radiators)

How many BACnet points does the Regin RegioArdo two-room controller (dampers, chilled beams, radiators) have?

This list has 455 BACnet objects: 235 analog values, 121 binary values, 99 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Regin RegioArdo two-room controller (dampers, chilled beams, radiators) BACnet points are writable?

239 of the 455 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 RegioArdo two-room controller (dampers, chilled beams, radiators) BACnet documentation?

The source is RegioArdo manual (MA30003), revision Rev. H, 2023-09-19, published free by Regin at https://www.regincontrols.com/globalassets/pimmediafiles/documents/regio_ardo_ma30003_en.pdf.

What are the minimum BACnet points to integrate the Regin RegioArdo two-room controller (dampers, chilled beams, radiators)?

Start with MV 30010 RegioControllerStateRemote (Unit state command: off, unoccupied, standby, occupied); AV 30001 RegioHeatSetPointOccupied (Occupied heating setpoint); AV 30002 RegioCoolSetPointOccupied (Occupied cooling setpoint); MV 30118 RegioFanSelect (Fan speed command: off, speed 1-3 or auto); BV 10009 RegioCommFailsafe (Heartbeat; write 1 to reset the failsafe timer); MV 40027 RegioControlState (Current unit state); AV 40026 RegioRoomTemp (Room temperature (internal or external sensor)); BV 20033 RegioSumAlarm (Sum alarm); BV 20042 RegioRoomTempSensorAlarm (Room sensor fault).

How do I enable BMS control of the Regin RegioArdo two-room controller (dampers, chilled beams, radiators)?

RegioControllerStateRemote (MV 30010) forces off, unoccupied, standby or occupied; 6 = no remote control hands control back to the controller's own logic.

Does the Regin RegioArdo two-room controller (dampers, chilled beams, radiators) need a BACnet heartbeat or have a communication timeout?

Optional communication heartbeat: when enabled (RegioEnableCommFailsafe, BV 10010) the BMS must set RegioCommFailsafe (BV 10009) to 1 within the failsafe time (default 10 min). If it doesn't, the controller goes to the configured failsafe state (RegioFailsafeState, MV 30182; default Off), raises an alarm and shows RegioCommFailsafeActive (BV 20099).

Can the BMS supply sensor values to the Regin RegioArdo two-room controller (dampers, chilled beams, radiators)?

In the BACnet list only the underfloor temperature can come from the network: set RegioRemoteUnderfloorTempSelect (BV 10012) and write RegioRemoteUnderfloortemp (AV 30202). The BMS can also shift the setpoint with RegioSetPOffsetRemote (AV 30009).

How do I check these points on the real RegioArdo two-room controller (dampers, chilled beams, radiators)?

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.
