Accurate Temperature Control

Temperature precision within 0.5 degree Celcius. Read external air temperatures or actual beer temperatures with a submersible thermowell.

Predictive Control

The Fermostat® predicts future temperature fluctuations based on previously collected data and adjusts the relay output accordingly, minimizing temperature overshoot and oscillations.

Straight-forward User Interface

A graphic LCD screen and scroll wheel with center button make interaction with the Fermostat® simple and intuitive.


Can be used to control a refrigerator, freezer, or even your own personally built contraption! Capable of withstanding a wide variety of environments. (Within reason... please don't submerse it in your bathtub.)

Internal Storage

Onboard memory stores all of your created programs as well as historical temperature and control data.

Removable Media

A microSD Card slot allows the transfer of data logs and programs to an external PC.

Dual Control

Simultaneously control both a cooling and heating unit to allow fermenting in a wide range of external temperatures.

Programmable Automation

With the Fermostat®, you no longer have to worry about having to fine tune and adjust the temperature of your fermentation/beer storage appliance.

Ease of Use

Out of the box functionality. Plug it in and it's ready to go! No electrician's expertise nor programming required for immediate use.

Cleverly Sophisticated

Use factory installed programs, or create your own programs to adapt to your particular recipes and methods; intricate or elementary, it's your choice.

Great Product
Very excited about this controller. Sturdy plastic case with hex headed screws to remove the cover. 6'6" cable to a 2" temperature probe. Scroll wheel control is easy to use. The menu is very intuitive and easy to use. So many options! Comes loaded with a lager program as well as an ale program that includes a cold crash. This is a very sophisticated piece of technology, and very well put together.

Great product so far!
Just started using this temp controller. Love that you can program it for just about anything. Rising temps. Free rise. Hold temps. Heat and cool at the same time. Whatever you need. Mine is working great right now raising the temp on some Belgian beer.

I was a little skeptical about this product but now I must say, where have you been all my life! Fully programmable for temp, rise, drop and hold. Well worth the money.
