The STC-1000 is a very popular homebrewing temperature controller. You could use this to control the temperature in the kegerator/keezer or to control fermentation temperature. It is dual stage, meaning that it can control a cooling and/or a heating source. It’s digital. At $19.99 shipped it’s also an amazing deal.
Some feedback on this controller from HBF Readers…
Jason says: Great controller! Love mine.
Jon says: I’ve built two controllers with these units. They work great.
Chris says: Mine works great.
It’s worth noting a couple of caveats on this controller. First, it is unwired. You’ll need to do some basic wiring to get this up and going. If you must have a pre-wired unit, check out our temp controller roundup post. Second, these are available through several sources. Make sure to get an appropriate voltage model. I would say the majority of these are solidly 220v. That model won’t work great for most of our readers. Third, to my knowledge, all versions of this read in Celsius only.
