Webasto auxiliary heater

Since I no longer have access to a garage in 2015, I had a Webasto auxiliary heater installed. I got the Thermo Top C with the TC3 SMS module. I don't find a timer particularly aesthetically pleasing in the interior. In 2025, I modified the emergency stop button by adding a fuse. I also installed two SMS modules, allowing me to control multiple devices via SMS; however, this remains a trade secret.
