The button "Single boost" only appears in hot water operating modes if the function for
ensuring a minimum temperature is activated. Actuating the button starts a once-only
boost backup mode. This can also be deactivated while it is in operation.
If the boost backup is actuated automatically based on the day of the week, time of day or
temperature, it cannot be deactivated by using the button.
