With the Grainfather Digital Temperature Controller, you can control the heating and the cooling (if you have the Grainfather Glycol Chiller) of your fermenter by dialing in a temperature or even setting a temperature schedule (can set up to 5 stages). This snaps on easily via magnets and pogo pins with no extra cords or clutter.
This upgrade kit allows you to get the most out of your Grainfather fermenter. The new controller enables you to control the fermentation remotely – to an exceptional degree of accuracy. With the upgraded Wi-Fi controller, you can easily connect to the Grainfather app and adjust the temperature wherever you are.
