Trying to update the color controller to version 2, have followed the procedure correctly. when buttons A and B are released the screen turns blue but prepare update does not show. Ironically the controller downloaded a data file to the SD card. Also I have a brand new 150 / 100 can version regulator, the color controller will not display the data even though its in the device list. The other controllers are 150/85 older units which the data is displayed.
