ronandsue74 Report post Posted August 11, 2021 My Saur Danfoss fan controller has been erratic and non operational for most of the time I have owned my 2005 Country Coach. A few years ago I began to develop an option to the Saur Danfoss controller. The Saur Danfoss controller gets it input from my ECM (electronic control module). It then controls the fan speed by regulating voltage to a electro magnetic valve. I concluded that if I could control the voltage going to the magnetically controlled valve I would be able to set my fan speed to an optimal highway rpm. I have been using the attached setup for the last three years with great success. I would like to share my relatively simple and inexpensive solution with those who may be experiencing problems with their Saur Danfoss controller.
