I have a Jobo CPE2 Plus drum processor with lift that has the temperature control locked at 99 F; at least, that is where my thermometer indicates the tempering bath stabilizes.
Now, I have had this unit for several years, got it in an auction but never have used it, and don't remember if this was the way it has always been, but am suspecting it was adjustable in the past.
Anyone ever heard of locking the thermostat on a CPP2? Would 99-100 degrees F make sense? Can you lock and unlock the unit?
I just recently washed the unit when I my darkroom was finished about 6 months ago; any chance it has rusted in place?
