How do I update the firmware manually on my Grainfather Conical Fermenter Controller?

To update the firmware on your GF30 Conical Fermenter, please follow the below steps:

If the unit is connected to Wi-Fi, it will prompt you when an update is available on the main screen. If this does not happen, do the following: 

1. Press the set button
2. Scroll down to 'about', and press set again
3. An option for checking for updates will appear
4. Tap this option, the controller will then check if an update is available if so, the controller will update as required.
