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.
