So Far So Good, Works For Sous Vide Cooking ! While sold and advertised as a thermostat control for regulating cooling devices for projects like beer brewing and such, the Johnson Controls Digital Thermostat is also capable of a Heat Mode that regulates temps up to 212 Fahrenheit; this is great news for anyone that is interested in setting up their own water oven for sous vide cooking!In order to do so the unit must be set in Heat Mode (it is set to Cooling Mode by default, indicated by a small snowflake icon on the display when the unit is on), to set the thermostat into Heat Mode you are required to open the unit up with a screwdriver and rearrange 2 small pins from partially connected to fully connected.

I also have a second one that I plan on using to operate a HERMS device for my mashing system. You can set the controller to operate a heater or cooling device but you must reposition “jumpers” inside the unit (not difficult but a pain if you plan on doing it often). If you want a unit that switches automatically betweem cooling and heating, you are better off with the more expensive Ranco controller.This particular controller will allow you to set the target temperature (as either a closing or openning point), the number of degrees of variance from target before the unit turns on/off, a time delay before the unit is allowed to reactivate the device(great for extending the life of a freezer or fridge), power supply on/off option in the case of unit failure and options for using remote monitoring/controlling if you…
