@merlingolf1 Hi - any particular parts of the app?
@merlingolf1 OK I cannot help you on that cos I have a combi boiler so have control over heating only. Sure someone will be along to help.
@merlingolf1 Click on the Hot Water tile and you get a pop-up. Click on the word Off and it changes to a toggle switch. Toggle it up and down to switch the hot water on and off. Click on the tick symbol in the top right hand corner and then set the duration for manual control.
