Siemens BSB Boiler System Bus Protocol

[ameliaamelia]

I just installed an heat pump equipped with the controller of SIEMENS RVS61.843/160.
The comunication with the controller is obtained through the BSB connector.
My goal is to control the heat pump through my home automation system.
Does anyone know this protocol ?

Thanks.

Hello amalia,
Just finished some of the same work on my Waterstage with RVS56.183 controller. The BSB is a Boilers System Bus for control between heating en thermostat etc. There is also a LPB bus (Local Process Bus) for connecting other apparatus for controlling the RVS.
In my case i bought a OZW672.01 webserver (in Greece!) to parameterize the heatingcontroller. There is a nice webinterface, but for controlling by means of external programs, you have to implement your own program and use the ajax.asp from the webserver.
see also http://www.ip-symcon.de/forum/f52/php-x ... gen-16098/
I have done (not quite finished) my programming in ASP.

You can see some of the data from the OZW672/RVS41 here: http://veldzicht.org/solar/siemens/rvs.asp
All data from OZW/RVS can be viewed and some parameters can be changed in the webinterface from the OZW.
There is fault history, but there is no logging of any data, so i have to build that myself on my homeserver.
I will post some sourcecode later (in ASP)
