JULABO F25-ME 4.5L REFRIGERATED/HEATING CIRCULATOR

Description

Unit powers up, runs, pump works, however I am unable to navigate menu to test cooling. I run into an endless stream of # of runs, start stop temp etc. Heating Cooling light never comes on. I believe it is a fully functioning unit purchased as working from reliable seller. Selling for parts because of inability to test cooling. Some sediments inside as shown in photos
