Vitogate 200 KNX + Vitodens200-W B2HB + Vitotronic 200 HO2C

[BMSEC-Solutions]

Dear sir,

First off all I would like to apologize if I ask something that is already documented, but I do not understand German, and I did not manage to find an answer. I also asked support form local (Romania) Viessmann representatives but they could not help me.

I am a certified KNX integrator and have to integrate a Viessmann boiler, but have no knowledge what so ever about Viessmann boilers.

The given boiler is: Vitodens200-W B2HB sn 7570779805688111
The automation used is: Vitotronic 200 HO2C sn 7743905867989116
And I have a Vitogate 200 type KNX connected.

My first issue is that I do not know what control unit to add under the Vitogate configuration because I can find an suitable combination.

Technical support from Romaina has no idea what to do. They suggested to try HO1 unit. So I tried VScotHO1_200_11, but **bleep** loading the configuration the Boiler display indicates error: E0: LON subscriber fault 98

Please assist.

Hello BMSEC-Solutions,

you have to choose VScotHO1_72. But if you have questions about that, please send us an email to customer-care@viessmann.com. We will forward it to our competent colleagues, so they can contact you directly.

Hello,
I have tried to add control unit VScotHO1_72 but it indicates that: The control unit is not present in the system or it has different system or subscriber number.
For the previously selected VScotHO1_200_11 it did not indicate this error.

[BMSEC-Solutions]

**bleep** discussing with the specialists, it turned out that VScotHO1_200_11 was the correct choice.
The error was due to the LON module in the Vitodens. The Lon module has been changed by Viesmann and the error disappeared.
