This is the latest controller box that replaces the old style relay model. Controller box is used in Webasto DBW-2010 Burner Head Aqua-Hot, Hydro-Hot RV Hydronic Heating Systems.
Note: There is “A” plug built in (not used in Aqua-Hot application. The A plug is for a Webasto stand alone unit that requires a head fuse) The bracket for mounting on the Webasto burner is built onto the controller.
This controller is for 12-volt systems ONLY.
Operation of “Diesel” light inside coach is different than the older boxes. On heating systems with an electronic board the switch light illuminates when burner is operation.
*Due to this part being an electrical component, it is a non-returnable item.*
