Flexit ProNordic with CS2500 controller (SP85 BACnet IP module) BACnet points list
Updated 12 November 2026
Flexit's overview spreadsheet of the BACnet objects in a ProNordic unit (CS2500 controller with the SP85 BACnet IP module). It has 79 objects: the BMS mode command, operating mode status, temperatures and setpoints, valve and pump outputs, five fan steps per fan, fan readings, filter pressures, fire damper status and A/B/C alarms. Many objects only exist when the matching accessory or configuration is present (marked S, C or A in the list).
This page lists 79 BACnet objects for the Flexit ProNordic with CS2500 controller (SP85 BACnet IP module) — 21 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Flexit’s own free documentation, linked below.

BMS integration notes: Flexit ProNordic with CS2500 controller (SP85 BACnet IP module)
Write MV 32040 BMS Regulation to run the unit from the BMS (Auto, Off, or Economy/Comfort steps 1-3). Adjust the comfort and economy heating setpoints if needed. Read MV 6080 for the actual operating mode, the outdoor/supply/extract temperatures, the fan values and the A/B/C alarm MVs; MV 19 resets alarms.
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
MV 32040 BMS Regulation selects Auto (unit follows its own schedule), Off, or a fixed Economy or Comfort fan step from the BMS.
Network setup
- BACnet IP needs the SP85 communication module on the CS2500 controller.
Watch out for
- MV 56125 temperature regulation mode is status only; Flexit says not to change it.
- Several instances are printed twice for different points; confirm against the live unit's object list.

Integration notes
- The spreadsheet has no read/write column. Access here is inferred: the BMS mode command, the alarm reset and the setpoint/fan-step AVs are marked W, everything else R.
- Printed instance clashes are kept as printed: AI 40895 is listed for both exhaust temperature and return water temperature, and MV 38643 for both B-alarm and C-alarm. AV 30463 and AO 30463 are different object types.
- BV 32321 Status AHU is printed as a Binary Value but with 17 state texts (2-18); check the type on the live unit.
- State texts follow the Norwegian sheet where the English sheet differs: MV 30094 1=Off/2=On and BO 5714 0=Normal/1=Alarm (the English sheet prints them the other way or 1/2).
- Fan step and fan value AVs are in Pa (pressure accessory), m3/h (standard) or l/s (by configuration).
- The file also has Norwegian and Swedish sheets with the same instances; names here are from the English sheet, typos included.
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 ProNordic with CS2500 controller (SP85 BACnet IP module) 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 Flexit ProNordic with CS2500 controller (SP85 BACnet IP module)
How many BACnet points does the Flexit ProNordic with CS2500 controller (SP85 BACnet IP module) have?
This list has 79 BACnet objects: 10 analog inputs, 8 analog outputs, 37 analog values, 5 binary inputs, 7 binary outputs, 1 binary value, 11 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Flexit ProNordic with CS2500 controller (SP85 BACnet IP module) BACnet points are writable?
21 of the 79 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 Flexit ProNordic with CS2500 controller (SP85 BACnet IP module) BACnet documentation?
The source is Overview Bacnet-object Flexit ProNordic (BACnet Flexit CS2500), revision 2024-09, published free by Flexit at https://flexitwebsiteprodstorage.blob.core.windows.net/product-documents/10670.
What are the minimum BACnet points to integrate the Flexit ProNordic with CS2500 controller (SP85 BACnet IP module)?
Start with MV 32040 BMS Regulation (Mode command: 1 Auto, 2 Off, 3-8 Economy/Comfort steps); AV 22817 Setpoint Komfort Heating (Comfort heating setpoint); AV 35713 Setpoint Economi Heating (Economy heating setpoint); MV 19 Reset Alarm (A,B,C) (Alarm reset); MV 6080 Operating mode Operation Aggregate (Actual operating mode (off, comfort, economy, start)); AI 45150 Supply temperature (Supply air temperature); AI 53218 Outdoor temperature (Outdoor air temperature); AI 28256 Extract temperature (Extract air temperature); MV 46769 A-Alarm Danger (A alarm active when 2); MV 38643 B-Alarm (B alarm active when 2).
How do I enable BMS control of the Flexit ProNordic with CS2500 controller (SP85 BACnet IP module)?
MV 32040 BMS Regulation selects Auto (unit follows its own schedule), Off, or a fixed Economy or Comfort fan step from the BMS.
How do I check these points on the real ProNordic with CS2500 controller (SP85 BACnet IP module)?
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.
