COMFORTCONTROL Thermo-Hygrometer
Features:
• Room temperature
• Indoor relative air humidity
• Maximum
and minimum
values
• Dew point
• Acoustic and optical alarm function in case of risk of
mould
The electronic COMFORT CONTROL Thermo-Hygrometer is
an ideal measuring instrument for checking room ambient
conditions.

Excessiv
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 variousrespects.Skin,mucousmembranesand
airways are adversely affected and pets, house-plants, woo-
den flooring and antique furniture mayalso suffer.
Active heating and ventilation can help achieve a comfort-
able and healthy living environment and may even saveyou
heating costs.
The interaction
of temperature
and air humidity:
If the room
air is too
humid,
ventilation
would
appear nonsensical in the winter, when the outside air is also
cold, dampandjust ashumid.
Cold air however, can absorb little or no moisture.
air enters the living areasit becomeswarmer.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 digi-
tal displayhow the relative humidity goesdown.
Dew-point:
This interdependency of temperature and relative humidity
is expressed by meansof the dew-point:
8
If the air is cooled continuously at constant absolute humi-
dity, then the relative humidity will steadily increaseup 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 indicatesan air temperatureof 200C
and a relativehumidity of 65%,then the dew-point tempe-
rature will be 13.20C.What does that mean?That the air, for
instance in your bedroom, will condense and form water
dropletsat all points on wallsand ceilingsthat are cooler
than 13.20C, and that this may later lead to patchesof
mould or damp.
If the air is at a relativehumidityof say40%,then the dew-
point temperature is only 6 oc.Thewallsand ceilingswould
therefore have to be significantly colder for the air to reach
its dew-point and for water droplets to form.
Howto achieve thecorrecttemperature a ndair humidity:
Tipsfor active heating and ventilation:
• Check the dew-point! Surfacesof walls should not fall
below a temperature of 150C!
• Donot turn the heatingcompletely off whengoing out.
at first
• Ventilatein all weatherconditions,evenif it's raining.
• Openthe windowsfor a short time (roomairing).A parti-
ally openwindow,for instance in the tilted position,does
not have the desiredeffect, wastesheating energyand
When this
can even promote the formation of mould.
• If the room air is too dry, particularly in wintertime, then
electrical a ir humidifiersarerecommended, sinceairing at
low outside temperatures will tend to decreasethe humi-
dity further.
Duration of airing:
• A few minutes are mostly sufficient. Checkthe value indi-
cated on your COMFORTCONTROL!
