I am having an issue with a Conviron E7/2, Serial number 100301. This device consists of two growth chambers operated by the same controller, a CMP6050. For some reason, I cannot change program information for the lower chamber. When I have the top chamber selected on the controller, I am able to edit, delete, and create programs. However, when I have the bottom chamber selected, the buttons that would allow me to insert, sort, or delete are shaded out to indicate that I cannot use them (SEE PICTURE), and when I click on them, they beep at me and do nothing else. Therefore, I need to know what is wrong and why I am unable to change the settings of the lower growth chamber. Any help you can offer will be tremendously appreciated!
