  overview

If the air is at a relative humidity of 40%, then the dew-point 

temperature is only 43°F. 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 59°F.

● 

Avoid shutting off the heat completely when leaving the house for 

extended periods of time.

● 

Ventilate in all weather conditions, even if it’s raining. 

● 

Open the windows for a short time to air the room. A partially 

opened window does not have the desired effect, wastes heating 

energy and can even promote the formation of mold. 

● 

If the room air is too dry, particularly in the winter, then electrical 

air humidifiers are recommended, since airing at low temperatures 

will tend to decrease the humidity further. 

● 

When airing a room, a few minutes should be sufficient. Check 

the value indicated on your Mold Alert thermo-hygrometer.

1.  Select °F/°C and place the audio alarm switch on the back of the 

unit in “on” mode.

2.  Slide off front compartment and install 2 batteries 1.5V AA. Once 

these are in place, the frowning face on the display will light up 

briefly and the alarm will sound for 2 seconds. 

3.  Replace battery compartment cover.

4.  Remove the protection film on the display. 

5.  The unit is now ready to use.
