That's better.![fing25.gif fing25.gif](https://www.t6forum.com/data/attachments/60/60593-c5a76f6125dc0368bc7a391d0199c005.jpg)
So position 2 on the telestart should be correct and it is more likely that it is the incorrect telestart. It seems like some sort of signal is being transmitted with a click being noticed.
My next step would be to connect the pin 2 to the yellow at the red plug and see if anything happens then. If W-bus is output I would expect some sort of response from the heater but with it being tied into Lin-bus full control will not be possible.
