Hello Alex! Eve Thermo works when hot water is always available. So while the boiler is off, the valve will work all the time trying to adjust the selected target temperature. What you could do to avoid ist use the function Schedule in the app Eve. Selecet the Comfort temperature for the time the boiler is on and 10 degrees while off. It will shut the valve then. Best regards, Volker
