Has anyone used an optional printer module as a dignostic tool on a UCP2 chiller? I remember it being talked about at the LaCrosse and Pueblo factory courses. You could temporarily hook up the printer module on a chiller that was having nuisance trips and it would save the last 15 minutes of operating parameters in it's buffer prior to the diagnostic, which you could then print out. Just wondering how well it works and can it be easily moved from chiller to chiller and is it easy to set up? Thanks
