Supported heating systems

BSB-LAN supports heating systems that communicate using either the BSB (Boiler System Bus), the LPB (Local Process Bus) or the PPS (Punkt-zu-Punkt-Schnittstelle). These controllers are usually manufactured by Siemens, older controllers might still bear the company name "Landis & Stafea" or "Landis & Gyr".

We have compiled a list of working models from various heating system manufacturers who have been confirmed working with BSB-LAN, although there is no 100% guarantee that the manufacturers keep the model name but change the controller to a different system. So always make sure to double-check that the right connectors are available.

Here are a few examples from heating controllers and the connectors that are used to connect to BSB-LAN. Some connectors have three pins, some have two pins. If there are three pins, make sure you choose the correct two (CL+ and CL-) as the third von (G+) is to provide background lighting for the room unit. It won't harm BSB-LAN, but it might be misleading because BSB-LAN's LED will be on even though it's not connected to the right pin.
