Want to brew lagers year round? Then the Refrigerator Thermostat Control, manufactured by Johnson Controls, is for you. Hook one of these up to that extra refrigerator and you're all set. This unit has a metal probe that you place inside the refrigerator or freezer. The probe reads the inside temperature, and adjusts to within 3.5 degrees of the temperature you set on the analog dial. This unit can be set between 20 and 80° F in one degree increments. Many brewers have found old refrigerators in the paper for 20 bucks, or even free. Add this unit and you'll be lagering in no time.

i was a little skeptical but this thing works real nice i was given an old freezer and i needed a beer fridge this worked great set the dial put the temp bulb in a neutral position , and plug it in
Installed in my basement in December and it works great!
So far so good. I opened it up and dropped it right out the box lol and it still works perfect. I used it for the first time on a java stout and it held the temp in my full sized refrigerator within 2 degrees
I am using this temperature on a dorm-style mini fridge. So far it works great. I have 2 thermometers in the fridge and the thermostat is accurate to within a degree or so and does not waver. Great product!
This is a great solution if you don't need the ability to heat and cool. I have it connected to a chest freezer. I monitored the temperature of my fermenter and the temperature inside the freezer with a thermometer in a bottle of water. After lots of observation and monitoring, here is the bottom line: The temperature of a bottle of water stays almost exactly at the temperature set on the controller. It is very accurate. The fermenter runs a little warmer during the first 2-3 days, due to high activity. It ran about 5 degrees above the temperature inside the freezer. Then it settled down to the same temperature as the freezer. This controller works great if all you need to do is cool. I live in a warm climate, so it works great for me. I highly recommend this. It isn't digital, but it is very accurate and works great.
