The CVT Select was designed by O Thompson for Millar. Some of the boards are no longer supported by Schindler but they are pretty easy to repair as long as the software is backed up. The few that I have seen out there in the field have used the DSD 412 Drive which is still fully supported from magnatek. This model in the picture has the mounted key board to program. I have also seen them with the tool port used for the MPH and Epoch series boards. You can use the same tool to program and the menu options are relatively the same as the Epoch 1. Good Luck!

I have some spare boards for this system if anyone needs them
