Viessmann Vitocrossal 200 CI2 (WAGO Automation Gateway) BACnet points list

Updated 28 October 2026

Short answer

Viessmann connects the Vitocrossal 200 CI2 to a BMS through a WAGO Automation Gateway that talks CAN to the boiler and exposes BACnet IP objects. The list covers external demand and operating-program commands for the boiler, DHW and four heating circuits, temperatures, burner modulation and hours, a second burner and O2 values, cascade sequence positions, fault codes and energy and gas statistics. Points must be selected in the gateway before they appear on BACnet.

This page lists 129 BACnet objects for the Viessmann Vitocrossal 200 CI2 (WAGO Automation Gateway) — 15 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Viessmann’s own free documentation, linked below.

BMS integration notes: Viessmann Vitocrossal 200 CI2 (WAGO Automation Gateway)

Integration in brief

Select the needed points in the gateway's web visualization and save, then set Heartbeat Monitoring. The BMS writes MV 3 for the heating program plus AV 2 (supply temperature) or AV 1 (modulation), and keeps rewriting MV 1 with 3 every 10 s so the boiler accepts them. Read flame, supply temperature, modulation, the fault flag and fault codes, and watch BI 1 for the gateway-to-boiler link.

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
MV 3	Boiler operating program: Target	Heating program: internal, modulation, supply temp, locked	Write
AV 2	Target supply temperature	Boiler supply temperature setpoint	Write
AV 1	Burner modulation, target value	Burner modulation command, 0-100 %; single boiler only	Write
MV 1	External demand	Write 3 (BACnet) every 10 s or BMS setpoints drop	Write
BI 2	Burner	Flame status; list prints 0 = On, 1 = Off	Read
AI 1	Supply temperature	Boiler supply water temperature	Read
AI 7	Burner modulation	Actual burner modulation, %	Read
BI 5	Faults	Any boiler fault present	Read
AI 14	Fault number 1	First active fault code	Read
BI 1	Connection to the boiler	Gateway-to-boiler link; 0 = no connection	Read

Enable & remote start

The BMS writes setpoints through the gateway's writable values: MV 3 picks the heating-mode program (internal value, target modulation, target supply temperature, target supply temperature exclusive, locked), AV 2 is the supply temperature target and AV 1 the modulation target. DHW uses MV 2 and AV 3; heating circuits 1-4 use MV 4-7 and AV 4-7. The boiler only accepts these while MV 1 External demand is written from the BMS (see heartbeat).

Heartbeat & communication loss

With Heartbeat Monitoring enabled (the gateway default, set in Project Settings), the BMS must write MV 1 External demand with 3 (BACnet) at least every 10 s. The gateway passes it to the boiler and resets MV 1 to 1; if the writes stop, the boiler goes back to its internal setpoints. With monitoring disabled MV 1 must still be written once, and the boiler keeps the last BMS setpoints after a communication loss.

Network setup

The gateway (WAGO PFC200 750-8212, BACnet IP, B-BC profile) ships with IP address 192.168.1.17; change it in Web-Based Management at https://<gateway-ip>/wbm.
No data points are published by default: in the web visualization (https://<gateway-ip>/webvisu/webvisu.htm) run Show data points, select the points the BMS needs, then save the project or the selection is lost on reboot.
The device instance, location and description are changed with the free WAGO BACnet Configurator; the device object name defaults to the gateway MAC address. The manual does not state a default instance.
Metric or imperial units and the data point language are chosen in Project Settings.
Cascaded devices mode handles up to eight boilers (CAN device IDs 70 for the master, 71-77 for the others); the master's objects use instances 1-1000 and each further boiler adds 1000.

Watch out for

The commissioning manual says to write 3 to MV 1 for BACnet, and that the gateway resets MV 1 to 1 after passing each write to the boiler. The point list numbers MV 1's states from 0 and lists BACnet as state 2.
When the gateway loses the CAN link to the boiler, the objects' Reliability changes to unreliable_other and their values stop updating.
BI 2 Burner is listed as 0 = On, 1 = Off, the opposite of BI 16 Flame burner 2 (0 = Off, 1 = On); confirm on site.
Once a configuration has been stored with the WAGO BACnet Configurator, point selection in the web visualization is greyed out; reset BACnet to factory settings to change it.
Command and setpoint points are not available on lag boilers in a cascade; the list marks which points apply to a single boiler, a cascade control unit and a lag boiler.

Integration notes

Applies to the WAGO Automation Gateway BACnet IP sold by Viessmann; the boiler connects to the gateway over CAN.
Only the BACnet IP objects are listed; the same document also gives Modbus TCP/RTU registers.
Temperatures follow the gateway's metric/imperial setting; the list gives ranges in both °F and °C.
Multistate states are shown as numbered in the list (from 0).
The list says the today gas counters (AI 36, AI 42) count in steps of 0.1 m³.
The list also has burner 2 and O2 probe points (AI 113-119, BI 16) and a hydraulic flap state (BI 15); the document does not say which boilers report them.

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 Vitocrossal 200 CI2 (WAGO Automation Gateway) 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 Viessmann Vitocrossal 200 CI2 (WAGO Automation Gateway)

How many BACnet points does the Viessmann Vitocrossal 200 CI2 (WAGO Automation Gateway) have?

This list has 129 BACnet objects: 85 analog inputs, 7 analog values, 16 binary inputs, 1 binary value, 13 multi-state inputs, 7 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Viessmann Vitocrossal 200 CI2 (WAGO Automation Gateway) BACnet points are writable?

15 of the 129 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.

Where is the official Viessmann Vitocrossal 200 CI2 (WAGO Automation Gateway) BACnet documentation?

The source is WAGO Gateway Data Points - Communication to a building management system (Vitocrossal 200 CI2) (6178 508-05), revision 01/2025, published free by Viessmann at https://www.viessmann-us.com/content/dam/public-brands/ca/pdfs/doc/wago/wago_gateway_vitocrossal_tdm.pdf/_jcr_content/renditions/original./wago_gateway_vitocrossal_tdm.pdf.
