24 Review(s)

Like the #7051, our Digital Temp Controller operates by overriding the internal thermostat in a refrigerator or freezer and gives the brewer greater control over the fermentation. Unlike the #7051, however, the digital controller has a digital display with adjustable differential. It can be used to heat or cool a fermentation environment - when hooked up to a refrigerator, it turns the compressor on when the ambient temperature rises above your programmed temperature; when hooked up to a heater, it activates when the temperature drops too low. A sensor probe monitors the temperature inside while the readout displays it in either Fahrenheit or Celsius. This is the ideal choice for lager brewers who include a diacetyl rest in their fermentations or for ales like altbier or Kolsch that require fermentation temperatures in the low end of the ale range.

Features a wide setpoint temperature range (-30° F to 220° F) and differential adjustment (1° F to 3° F). The temperature sensor is a 1.94 inch thermistor on an 8 foot cable.

Brew system revolves around this. Review by Doug

Rating

Compared to all other brew system investments this digital temp controller has become the center-piece of the whole 4 to 6 week process. Everything else can be executed perfectly, but temp control for weeks on end will help protect your results of time and money spent...not to mention better control of flavors. My first controller (and not my last) has been working flawlessly for 6 months and it is easy to use. (Posted on 5/11/12)

Good product Review by brandon

This is great and easy t figure out, i thought you could actually make a freezer heat, but i don't think you can. I just put a small heater in the freezer, took the cover off the unit and moved the jumpers to jump and works great. changed and took the jumpers off for some lagers and still works great. that was with the freezer hooked up on cooling mode. THIS IS A MUST HAVE if your interested in making consistent brews. (Posted on 3/12/12)

Excellent Product Review by strizzlenuri

Awesome! Well worth the $80 if you are a home brewer. There are many settings which are explained in the directions.

I used this product with a mini fridge that I "modified" to be able to fit a 5 gallon carboy with an airlock into.

No wire splicing. Just plug the Johnson Control unit wire into a 110 outlet and your fridge into the control unit... good to go. Set it and forget it... for about a month to 6. Worked perfectly for my Oktoberfest Lager. (Posted on 2/21/12)

trouble free set-up Review by amblansman@yahoo.com

I'm using it in a chest freezer to provide me a place to cure pork and brew lagers. It is trouble free to set up as long as you have a good way of getting the thermistor inside the freezer. (Posted on 11/27/11)

Great Control Review by Ryan

Rating

Very easy to use, all the above reviews are spot on. I am continually impressed with how little stress this places on the freezer it's controlling. The unit cycles on once every 20 min or so to maintain temps within a +/- 1 deg variance. Great product. (Posted on 10/26/11)

Couldn't be better Review by RJohnson

Rating

I've used this for two years, not just for brewing but also for a concessions business. As the description notes, there's a digital display of my unit's internal temperature, which is handy. It even remembers its previous setting when left unplugged for months. After a time, I drilled the freezer wall and inserted the probe through it rather than closing it in the door. A little plumbers' putty and it's all good. (Posted on 10/20/11)

Hot in Florida Review by John

Rating

Works great. South Florida is always warm and I have my freezer outside beside the bar. When the air temp is in the 90's it keeps my fermentarium at 65. You can't go wrong if you are having a problem controlling the brewing temp. (Posted on 8/28/11)

Easy to use and a must have. Review by Jerry

Rating

Just finished a doppelbock and a Munich dark lager in my chest freezer. This controller never missed a beat and was very simple to set up and use. I had an ale fermenting on a counter in my basement and the daytime temps were a degree or two higher then I wanted. I brewed a few more ales and put all three carboys in the chest freeser and now my temps are perfect. Save yourself a lot of hassle and buy one of these. You will not be disappointed.

Excellent Investment Review by MJG

Fantastic addition to my brewing equipment. Easy to operate, anyone can follow the directions and set this up. Good control over the temperature has turned my spare fridge into the perfect lagering control center! I can't wait for my Oktoberfest this fall (Posted on 7/3/11)

Okay I bought two more over the winter. Review by Matthew

Rating

I bought two more of these and attached heating lamps. Now I have 4, two for cooling and two for warming. I use them with my two fermentation refrigerators.

We had a colder than normal winter in Texas. Two more controllers worked great for when my unheated brew room was dropping below optimal fermentation temperatures. I have gotten all of them dialed in so I am always within plus or minus 2 degrees of my target temperature.

Summer is here so now my other two used for cooling are kicking in.
