The BTU XT app is designed to provide the storage manager with a simple and easy human machine interface (HMI) to view and control the environment in multiple agriculture storages. This is a secure interface using a user name and password. Once logged in, the app will display the status and main parameters of all authorized units on a main summary page. Each unit can then be selected and multiple displays will show all data and status of equipment. Pages are selected by swiping sideways. A single touch will bring back the summary page at any time. This app allows the user to make changes to any of the control panel parameters. When making parameter changes, a second login unique to the selected panel must be verified for security. All screens in this app are identical to the local HMI so the user will be familiar with the operation.
