Hoval TopTronic E BACnet datapoints, use case 7 (heat generator, 3 circuits, hot water, buffer, ventilation) BACnet points list
Updated 12 November 2026
Hoval's "use case 7" signal file maps 58 read-only analog inputs for monitoring a larger TopTronic E system: heat generator temperatures, modulation, status, hours, cycles, thermal and electrical power, COP, energy totals and heat pump fault code, plus flow, setpoint, mode and pump status per heating circuit, hot water and buffer tank temperatures, and ventilation mode, VOC, temperature and humidity.

BMS integration notes: Hoval TopTronic E BACnet datapoints, use case 7 (heat generator, 3 circuits, hot water, buffer, ventilation)
Load the Hoval use-case project into the Intesis BACnet gateway connected to Hoval Connect over Modbus TCP, then trend the heat generator, circuit, hot water, buffer and ventilation values. Nothing is writable in this set.
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.

Integration notes
- The file is an Intesis MAPS signals export (Modbus master to BACnet server) that Hoval publishes for its BACnet gateway; the mapping can be edited on site, so treat this as the factory default.
- Object names are the Name column (German); descriptions here are English translations. WEZ = heat generator, HK = heating circuit, WW = domestic hot water.
- All objects are AIs with no write function (monitoring only). Status, mode and fault values are numeric codes.
- The file sets units code 62 (°C) on every object, including hours, counts, power and COP; units are kept here only on temperature objects.
- Project name in the file: IN-BAC-MBM_Testanlage (a test installation), Intesis MAPS 1.2.33.0. The "use case 3 and 4" file only has 3 objects and is not listed.
- The file does not say whether the gateway serves BACnet IP or BACnet MS/TP; check the gateway configuration.
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 TopTronic E BACnet datapoints, use case 7 (heat generator, 3 circuits, hot water, buffer, ventilation) 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.
