COMFORT CONTROL – Thermo-Hygrometer
The electronic COMFORT CONTROL Thermo-Hygrometer is an ideal measuring instru-
ment for checking room ambient conditions.
Excessive room-air humidity can damage your health and promotes the formation of
damp patches and mould.
But excessively dry room air can also affect our well-being and health in various
respects. Skin, mucous membranes and airways are adversely affected and pets, house-
plants, wooden flooring and antique furniture may also suffer.
Active heating and ventilation can help achieve a comfortable and healthy living envi-
ronment and may even save you heating costs.
The interaction of temperature and air humidity:
If the room air is too humid, ventilation would at first appear nonsensical in the winter,
when the outside air is also cold, damp and just as humid.
Cold air however, can absorb little or no moisture. When this air enters the living areas
it becomes warmer. And then the air can absorb much more water vapour. After just a
few minutes of giving a room an airing, you can see on the digital display how the rela-
tive humidity goes down.
Dew-point:
This interdependency of temperature and relative humidity is expressed by means of the
dew-point:
If the air is cooled continuously at constant absolute humidity, then the relative
humidity will steadily increase up to a maximum of 100%. If the air is cooled further,
then the excess water vapour is separated out in the form of water droplets.
If the measuring unit indicates an air temperature of 20° C and a relative humidity of
65%, then the dew-point temperature will be 13.2° C. What does that mean? That the air,
for instance in your bedroom, will condense and form water droplets at all points on
walls and ceilings that are cooler than 13.2° C, and that this may later lead to patches of
mould or damp.
If the air is at a relative humidity of say 40%, then the dew-point temperature is only
6 °C. The walls and ceilings would therefore have to be significantly colder for the air to
reach its dew-point and for water droplets to form.
How to achieve the correct temperature and air humidity:
Tips for active heating and ventilation:
• Check the dew-point! Surfaces of walls should not fall below a temperature of 15° C!
• Do not turn the heating completely off when going out.
• Ventilate in all weather conditions, even if it's raining.
• Open the windows for a short time (room airing). A partially open window, for instance in
the tilted position, does not have the desired effect, wastes heating energy and can even
promote the formation of mould.
• If the room air is too dry, particularly in wintertime, then electrical air humidifiers are rec-
ommended, since airing at low outside temperatures will tend to decrease the humidity
further.
