I talked to a tunnel operator who is having an issue with this controller. He has the tire shine programmed for only two of the washes, but it comes on every wash. He has called DRB and the people who installed it and everyone is scratching their collective heads. (Actually the installers told him they would fix it if he bought more tire shine. The place is 16 months old.) I'll be going there in a couple days and wanted to get some ideas first. Any thoughts?
