Good video. I have a Thermo Top C from a 2004 Range Rover, do you know if this unit is analog, and if not what is the best way to tell, since as you say pinouts are hard to find?
Brilliant video very informative..iv got a webasto air top evo marine 3900..iv spent hours looking for the pin to do a diagnostic test ect..iv tryed all the pins and get 12v dc readings..I was expecting 5v on pin 12 or pin 10 (no wire or plug pin installed) any help or advice would be much appreciated..thanks justin
I have a similar but not identical thermo top c/z controller from BMW, it uses the same circuits shown in the clip and the same connections 1=communication, 2 Can Hight, 3 Can Low
Hello ! I have a factory made heater in my mercedes w203 ( c270) . And i installed it back with my factory cabels . but its only just spinning the air fan, and i cant controll it from my cars menu . What you think this can be the same issue ? anyway theres no blue wire micro soldered in my electric board.
Hi, i have tried to find the Pinout for my ThermonTop C out of a Mercedes. Was not succesful so far. Can you help me out how to find it ? Is WTT able to communicate trough the Can high and low ? I know them Pins.
No! wtt uses "W-Bus" or "webasto diagnostic bus". Think of the board as two systems in one! one system is merc and can, the other is webasto and there diagnostic bus. So can is only for the merc! W-bus is k-line! this is pin 1 or 2 with k-line adaptor and wtt. hope that helps
@@robinsonlabs okay i have checked pin 1 (plug) to pin 6 on the L9637 and had a match ... hooked up my adapter and software and choose W-Bus ... it automatically worked and has shown all the options opened when connected. made a quick testrun and almost shit my pants in happiness :D thanks mate !!! you really helped me out there !

so sorry for the late reply, you can find anything for your heater here www.butlertechnik.com/technical_library/air-top-evo-3900-d23
the source will be powered and will provide 5 volts, only when pin 3 is put to ground (Can Low)

Sounds like a supercharger circuit fault! by all means pop over to the website and book an inspection/repair www.robinsonlabs.co.uk
@@robinsonlabs It would be great but im living in the other side of europe :)
