Sontex BACnet MS/TP module for Supercal 531 / Superstatic 440 / Superstatic 449 BACnet points list
Updated 12 November 2026Unofficial source
The Sontex BACnet MS/TP module plugs into a Supercal 531 / Superstatic 449 integrator (or a Superstatic 440 meter) and serves its readings as read-only Analog Inputs: energy and volume totals and per-tariff values, two auxiliary pulse counters, flow and return temperatures, power, flow and running hours, plus the same totals stored on two set days. Units follow the meter's configuration.
This page lists 31 BACnet objects for the Sontex BACnet MS/TP module for Supercal 531 / Superstatic 440 / Superstatic 449 — 0 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from a copy of Sontex’s documentation hosted by BACnet International, not by Sontex itself, so treat it as unofficial.

BMS integration notes: Sontex BACnet MS/TP module for Supercal 531 / Superstatic 440 / Superstatic 449
Set a unique MS/TP MAC address with Prog531 / Prog449 (the default 255 is auto-MAC), read the device instance from the software, then read energy, power, flow and temperatures.
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 |

Network setup
- MS/TP master or slave, MAC 0-127; default MAC 255 (AutoMAC). Change it with Prog531 / Prog449.
- Baud 9600-115200 or auto baud.
- Bus termination by DIP switch S1.
Watch out for
- Energy and volume units depend on the meter configuration (MJ, GJ, Wh, kWh, MWh, BTU; m3 or US gallons).

Integration notes
- Object names carry the instance (e.g. 'AI-10-Power'); they are kept as printed.
- Both set-day date objects are printed as 'CA-0' (CA-0-Set-Day1 and CA-0-Set-Day2); they are listed as printed, so the second one clashes with the first. They hold a BACnet date (year, month, day). Check the second calendar's real instance with a device scan.
- Units are a list of allowed units; the one in use depends on the meter setup.
- The data sheet gives no read/write column; all objects are measurements and are listed read-only.
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 BACnet MS/TP module for Supercal 531 / Superstatic 440 / Superstatic 449 and exports what it actually has to Excel — free.

Questions about the Sontex BACnet MS/TP module for Supercal 531 / Superstatic 440 / Superstatic 449
How many BACnet points does the Sontex BACnet MS/TP module for Supercal 531 / Superstatic 440 / Superstatic 449 have?
This list has 31 BACnet objects: 29 analog inputs, 2 calendars. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Sontex BACnet MS/TP module for Supercal 531 / Superstatic 440 / Superstatic 449 BACnet points are writable?
None of the listed objects are marked writable in the source documentation. The source has no read/write column, so this is inferred from object type.
Where is the official Sontex BACnet MS/TP module for Supercal 531 / Superstatic 440 / Superstatic 449 BACnet documentation?
Sontex does not publish it on its own website. This list comes from BACnet MS/TP module for Sontex Thermal Energy Meters (data sheet with PICS), revision 28-10-2016, a copy hosted by BACnet International at https://www.bacnetinternational.net/catalog/manu/sontex%20sa/data_sheet_bacnet_ms-tp_module_en_28-10-2016.pdf. Ask Sontex or its representative for the current revision.
What are the minimum BACnet points to integrate the Sontex BACnet MS/TP module for Supercal 531 / Superstatic 440 / Superstatic 449?
Start with AI 0 AI-0-Energy (Energy total); AI 10 AI-10-Power (Thermal power, W or kW); AI 11 AI-11-Flow (Flow, m3/h); AI 8 AI-8–High-temperature (High (flow) temperature, °C); AI 9 AI-9–Low-temperature (Low (return) temperature, °C); AI 1 AI-1-Volume (Volume total).
How do I check these points on the real BACnet MS/TP module for Supercal 531 / Superstatic 440 / Superstatic 449?
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.
