Hello WoMo Friends I would have asked the following question about my Trumatic SL 3002. Now that the cold period is beginning so slowly, I looked a little closer at the heating installed in my WoMo and wanted to check it for functionality. Since I have the WoMo only recently, I wanted to see if everything is going as it should. In doing so, I noticed that it has a so-called Pietzo ignition and therefore my question: How is the function of the same and where does it relate to as I have seen in the net, it should actually have a battery compartment and this is not available with me talk heating. Therefore my question.!! So who could please explain this to me, I would be grateful to him. Thank you Walter
