Axioma Metering Qalcosonic E3 / E4 heat meter BACnet MS/TP module BACnet points list
Updated 12 November 2026Unofficial source
A plug-in BACnet MS/TP module for the Qalcosonic E3/E4 heat meter. It polls the meter (default every 300 s) and serves 14 read-only Analog Inputs: heat and cooling energy, tariff registers, volume, two pulse inputs, power, flow, flow/return/differential temperature and the meter info code.
This page lists 14 BACnet objects for the Axioma Metering Qalcosonic E3 / E4 heat meter BACnet MS/TP module — 0 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from a copy of Axioma Metering’s documentation hosted by AxFlow, not by Axioma Metering itself, so treat it as unofficial.

BMS integration notes: Axioma Metering Qalcosonic E3 / E4 heat meter BACnet MS/TP module
Read-only meter: poll heat energy, power, flow and the two temperatures, and alarm on the info code.
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 |
|---|---|---|---|
| AI 1 | Accumulated heat energy (E1) | Heat energy total | Read |
| AI 11 | Actual power | Thermal power | Read |
| AI 14 | Actual flow | Flow rate | Read |
| AI 19 | Flow temperature / Temperature 1 | Supply temperature | Read |
| AI 20 | Return temperature / Temperature 2 | Return temperature | Read |
| AI 30 | Info code (Error code) | Meter error / info code | Read |
Network setup
- MAC 1-127 follows the meter's M-Bus address; baud 9600-115200 (default 38400), 8E1.
- Data refresh interval defaults to 300 s (configurable).
- A RESET button restores module defaults after a bad configuration.
Watch out for
- Values update only at the module's polling interval, not continuously.

Integration notes
- Instances are sparse (AI 0-6, 8, 11, 14, 19-21, 30) as printed in the object table; the Object_List example on p4 numbers them differently, the table IDs are used here.
- Energy units follow the meter set-up (kWh or MWh); pulse inputs may be volume or energy.
- Vendor ID 1006. Device instance = last 5 digits of the meter serial number.
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 Qalcosonic E3 / E4 heat meter BACnet MS/TP module and exports what it actually has to Excel — free.
