DetailsThe first dual-mode digital temperature controller to go from -50°F to 300°F—and back again—with the flip of a switch. Forget the Ready, its low-profile, ultra-mountable design is Set and Go. With a responsive dual-color LED display and modular probe that eliminates the need for a thermowell, perfect homebrew has never been so effortless.
No longer is an advanced degree in electrical engineering required to achieve flexibility in fermentation temperature control. ThermoStar® is the only temperature controller that you'll never need to disassemble or re-wire for perfect performance. With ThermoStar®, switching from heating to cooling is not only easier than ever with the simple push of a button, it is instantly recognizable with an LED screen that displays the target temperature in blue when the unit is in cooling mode and red when it is in heating mode.
A low-profile design outfitted with multiple mounting options—everything from magnetic to suction to nail hooks—ThermoStar® delivers superb, reliable control even in the smallest of fermentation spaces.
Upgrade the modular stainless steel probe to our longer 12” model and monitor the actual internal fermentation temperature of your wort without the need for a thermowell.

4.8 / 5.06 ReviewsThermostar Digital ControllerGreat addition to the arsenal of homebrew equipment. Brewing in the heat of the Florida Keys provides numerous challenges (e.g., cooling water, fermentation, bugs flying into wort) and perhaps the largest was fermenting anywhere near optimal temperatures. With the help of a retired chest freezer and the Thermostar I have been able to make a couple of batches of ales where you can really taste the difference that fermenting at 65 versus room temperature (77) makes. I currently have an Octoberfest lager in its second month of cold fermenting (37 degrees), something that, down here, would be impossible without temperature control. Awesome product for a world without basements or seasons to help regulate the ambient air temperature.August 4, 2016ExcellentI brew in my basement which is very cold during winter months and was affecting my ale fermentation. The ThermoStar has elevated that issue.February 25, 2016Works Great!In the past I've used the analog Johnson control, but this controller is well worth the extra money. I've paired it with a chest freezer and have loved the results. My Johnson never seems to keep the correct temp, but the Thermostar holds the temp within a few degrees consistently. Add in the ability to switch to a heater and I can use it to keep an area warm on those cold winter nights. Works great!August 12, 2014Great ProductMake sure to check your settings. My default was plus or minus 3.7 degrees. Easy enough to change. I have a Johnson controller on my keezer and got this to try out on my fermentation chamber. So far I like it much better. It is very easy to change into heating mode, it has a great display, the modular probe is great, and it has a built in magnet that sticks right to the fridge. No complaints so far. 5 stars.January 18, 2015totes perf.Great value! Thing works perfectly.July 31, 2016Nice UnitI bought this when they offered a free 12" probe with purchase. The setup with a 12" probe works really good in my better bottle using a standard carboy cap. The only issue I had was with the original settings. The directions indicate that the temperature differential factory setting was 2, however, my unit was set at 3.7 degrees. Fortunately I was around for the day during my initial test, so I caught it and was able to change it to 2. I am currently fermenting an IPA in a 50 degree room, using the temp controller with a heat belt. I set the temp at 68 and it kicks the heat back on when it drops to 66. Very happy with this unit.December 10, 2014

Browse 4 questions Browse 4 questions and 4 answersTo follow up to the answer of Rob's question, will this work in a 6 gallon carboy if I get a solid stopper and drill it to the proper size to insert the probe and wire?BEST ANSWER: Yes, that would be fine to do, as long as only the probe is in the liquid. The long probe is of course best for this use. -Mike W, Midwest SuppliesCan I order the original temp probe it comes with?BEST ANSWER: Unfortunately, we do not sell the standard probes by themselvesCan I program a profile into it, for set datsomething for temperature increases or decreases ahead of time?BEST ANSWER: This controller does not use programmable profiles. You would need to set the temps manually.Does the probe fit into a thermowell? I think the one on my fast ferment is 1/4"BEST ANSWER: Unfortunately not! At least it does not fit the thermowell we currently carry, and yours may be similar. It can be used with a solid stopper that you drill out to the proper size, though. -Mike W, Midwest Supplies
