Relative humidity is the ratio of the mass content of water vapor in the air to the maximum possible mass at the given temperature; relative humidity is measured in percent and is indicated, for example, as «45%».
Atmosphere air always contains water vapour, percentage of which depends on meteorological conditions; the higher the temperature, the more water vapour is contained in the air. When cold air is heated up to comfort temperature in winter, relative percentage of water vapour decreases, this is what relative humidity is.
To maintain comfortable room conditions, water or water vapor must be artificially added to the ambient air — this is what the air humidifier is necessary for.
Comfortable relative humidity for humans is «45-65%»; «40-55%» for preventive and medicinal purposes; for furniture, musical instruments and libraries it is recommended to maintain relative air humidity of «4060%».

Consequently press/touch the button (15) « » to set the desired level of relative humidity in the room within the range from 40% to 80% which will be shown with the symbols (22), the symbol « » will light up on the display in the operation mode icons row (19).
When the desired humidity level is reached, the air humidifier will be switched off, when the relative humidity level decreases, the air humidifier will switch on.
To switch the selected humidity maintenance mode off press/touch the button (15) « ****» until the flashing symbols «- -» (22) appear.
