We had no real way to regulate the temperature on our new display refrigerator. The internal thermostat keeps the temperature at 39 degrees F no matter how you set the dial.

This controller will allow us to dial in the temperature to within 1 degree Celsius. We have ordered a controller that will control heat as well as cooling. When that one arrives, we will put it into this enclosure and move the current, cool only, controller to the kegerator.
We will add some kind of element to warm the fridge for those very few nights when the ambient temperature might bring the fridge temp to below our target. This is probably overkill, but temperature control is vital to good fermentation. Lagering is something we want to get good at too.
