The STC-1000 is versatile digital temperature controller. It’s manufactured by a number of manufacturers
Specifications can very but you can generally speaking these are dual stage temperature controllers that you can use to help control temperature of your kegerator, fermentation chamber or as part of your brew system. Dual Stage means this can control a heating and cooling device. Alternatively, it can control a heating or a cooling device. Note that these are unwired controllers and will require some work to implement in your project.
STC-1000 vs ITC-1000
The STC-1000 is a great controller, arguably the best value in temperature controllers, especially if you’re on the handy side. The ITC-1000 from Inkbird is what I would call and upgrade to the STC-1000. The big upgrade is that the ITC-1000 display ins deg F and deg C, where most versions of the STC-1000 were deg C display only. Beyond there, it’s my understanding that there are some usability improvements in the ITC-1000.

Some things to consider when buying an STC/ITC 1000 controller
- Input voltage. These can be powered by DC and AC 120 to 240
- Readout capabilities. Many STC-1000 controllers read in Celsius only. Some have the ability to read in Celsius or Fahrenheit.
The American Homebrewers Association has a great write up on a step by step build out of an STC-1000/ITC-1000 Temperature Controller Build. It includes a parts list, pictures and diagrams along with a step by step how to for getting this going.
How to Build a Temperature Controller for the AHA
by Duncan Bryant
This dual-stage temperature controller is perfect for managing temperatures of your kegerator, fermentation chamber or keezer. It allows for a hot and a cool trigger to be individually controlled, so you could have your fermentation refrigerator hooked up to the cold trigger and a heat source to the hot trigger. If the temperature falls below the target value, the heating device will be turned on, and vice versa.
Note: this project deals with electrical current and DIY’ers should pursue the build at their own discretion. Read through the directions entirely to have a full understanding of the build before diving in. If you are unsure of your abilities, consult with someone well versed in electrical wiring.
Make sure the components you use are compatible and rated for your intended application. Contact manufacturer with questions about suitability or a specific application. Always read and follow manufacturer directions.
