Hello Graham! When using the app Home from Apple the difference is weather Eve Thermos is heating in this moment to reach the target temperature you set or if it is reached. At the end of the heating season I set Mode and Schedule to Off in the app Eve. The valve is closed then.
Eve Thermo requires hot water to be available all the time to operate, a boiler can't be controlled, sorry. Best regards, Volker
