Alright, I need to create a selling description for the Sit 503 EFD 0.503.501 topochny avtomat. Let's start by understanding the product. It's a furnace controller, so the main features would relate to safety, efficiency, and ease of use. The user wants me to use the fields Name, Description, and Characteristics.
