Webasto Thermotop V
I have been given Shocked a Webasto Thermotop V because my friend couldn't get it to work. I have done some research and found that it is the same as fitted to Discovery 3's. It is not controlled in the same way as the C (by applying 12v to [pin 2?]) But via W-bus signal.

Basically I'm looking for help from someone who is much cleverer than me to help me write some code to run it with an arduino or microcontroller.

I can handle the physical fitting (although any pointers are greatly accepted)

There is a video on YouTube of a guy who has an arduino running one but I want to simplify his code to work without all the LCD screen and buttons. If there is an off the shelf solution to this problem then I would much rather that!

The quicker I can get it running on the bench the quicker I can have pre heated loveliness and faster warm up times Mr. Green

Any help or pointers would be greatly appreciated Thumbs Up 2002 90 Td5 Station Wagon

If you've not seen it, have a look at www.disco3.co.uk/fbh

I've got lots of wiring parts for the TTV: http://www.defender2.net/shop/webasto-wiring-parts-c15.html

Also look at the Webasto section of DISCO3 forum: https://www.disco3.co.uk/forum/webasto-fue...-vf96.html

There are a few off-the-shelf controllers available (Altox, BAS, etc)  1988 90 Td5 NAS soft top

After a fair bit of googling I've found this. Does it look up to the job?
