Connection to Webasto AirTOP EVo 5500


Norwegian buyer here, and I’m new to VanPI and new to this forum. Bought a complete unit with relay board to test out in my boat, and to get remote access to my Webasto heater. I also bought the Webasto cable.

But there is no documentation on how this should be connected? What colors in the Webasto cable loom should I connect this to? I will run the VanPI from my 12v system in the boat, but the Webasto heater is on 24v, if that changes anything. Both 12v and 24v have common negative/ground.

Would appretiate some help! :slight_smile:

Hey Andersh.

you can find the instruction here:

The adapter should also work with 24V Signal.
