Here you can find the installation scheme, which will be updated every 5 minutes, when my PC is online. This update is done by the great program SolStat, which is a solution of J.M. software solutions GmbH.  With this nice program you don't have to walk downstairs to your controller to read your temperatures. And further on it displays the graphs of the logfiles. 

I produced this scheme with MS Visio. It will be used as background and SolStat puts the values read to the positions you determine.

I used two unused wires of our telehone system which I connected to the UVR1611 controller in the cellar and to the data logger D-LOG/USB which is connected to my PC in the attic. The data logger from Technischen Alternative is provided with each BUSO installation.
