The thermostat is indeed digital.
Short answer is cooled CCD/CMOS cameras do not like water vapour in their chambers as it can show up as ice on a sensor when cooled below freezing.
Desiccant chamber plugs are one fix for that problem.
But...when 'de plug is full of water, it needs drying out...or replacing. (read $$)
Water boils at room temperature in a good vacuum. Place the plug in a heated vacuum....Voila!
Problem solved
