Ranco ETC (Electronic Temperature Controller) model 111000.  Single stage digital temp controller,

• Use as an overriding thermostat to control your compatible kegerator chest freezer, refrigerator or fermentation chamber.  I believe this is an unwired unit.  If that’s the case, you need to manually wire it yourself.
• Why would you choose this over something like the Inkbird Dual Stage Temp Controller?  The Ranco is generally more expensive and offers fewer features when compared to the ITC-308.  In my opinion, the advantage that the Ranco does have is ruggedness.  These are built for commercial applications.  This question in my mind is… do you need a rugged commercial quality unit?  If yes, then this is a controller you may want to look at.
