The summer / winter heating limit is used to switch the heating on and off in the course
of the year, depending on temperature conditions. In Automatic mode, switching on / off
takes place automatically, so there is no need for the user to do this manually. By
changing the setting, the respective periods of time will be shortened or extended.
