Wildeboer WiVent-B decentralised ventilation unit, BACnet IP BACnet points list

Updated 12 November 2026

Short answer

The WiVent-B is a decentralised facade ventilation unit for classrooms and offices. Its Beckhoff CX9020 controller runs TwinCAT BACnet over BACnet IP and publishes a schedule and holiday calendar, command switches and push buttons as Binary Values, status and alarm flags as Binary Inputs, airflow and temperature settings as Analog Values, measurements for the master and up to five slave units as Analog Inputs, and operating mode, faults and warnings as multi-state objects.

This page lists 115 BACnet objects for the Wildeboer WiVent-B decentralised ventilation unit, BACnet IP — 39 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Wildeboer’s own free documentation, linked below.

BMS integration notes: Wildeboer WiVent-B decentralised ventilation unit, BACnet IP

Integration in brief

Command the operating mode with MSV 400 (or let the internal schedule run), keep the watchdog alive if it is enabled, and read the operating mode status, room temperature, CO2 and the fault and warning flags.

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

BV 201	WiVent_Takt_Watchdog	Watchdog pulse, toggle faster than every 10 s	Write

BI 260	WiVent_Warnung_1B	Warning with unit shutdown	Read
MV 460	WiVent_Warnung_System	System warning code (filters, schedule)	Read

Enable & remote start

MSV 400 sets the operating mode; BV 204 (external release) and BV 205 (external fault shutdown) put the unit into protection mode.

Heartbeat & communication loss

BV 200 enables a connection watchdog; BV 201 is the watchdog pulse and must change faster than every 10 s. The document does not say what the unit does when the pulse stops.

Network setup

BACnet IP on the Beckhoff CX9020 (TwinCAT BACnet, vendor ID 415); the PICS also lists MS/TP via an EL6861 terminal.
The full set of objects for a given installation is defined in its EDE files.

Watch out for

Filter test, filter drying, presence and fault acknowledge are push-button Binary Values; write active, not a held state.
State texts of the multi-states are German.

Integration notes

The interface description is in German; object names, state texts and Active/Inactive texts are kept as printed and descriptions are translated.
The table has no read/write column; Binary Values, Analog Values, the schedule, calendar and MSV 400 are listed as writable (settings, switches and buttons), inputs and status/fault multi-states as read-only.
Some names are printed in quotes ("WiVent_Betriebsart"); the quotes are dropped here.
Defaults and limits printed for the Analog Values can differ after system parameterisation.
Slave objects only report when slave units are connected (AI 378 = number of active slaves).

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 WiVent-B decentralised ventilation unit, BACnet IP and exports what it actually has to Excel — free.
