suggestions for Placement of the unit

There is an opening on the back of the unit, which allows it to be easily 

hung from the wall. In addition, a base is provided for the unit to be 

placed on any surface in a standing position. 

Since the humidity level within rooms can vary greatly, the Mold 

Alert should be placed in an area most likely subject to mold growth. 

Problem areas are often basements, closets, surfaces near windows 

and exterior walls. Anywhere in a home that is damp or has suffered 

from water damage is also a prime location for mold growth.

Three values of measurement are displayed simultaneously.

The left column shows the indoor relative humidity (%), the middle 

column indicates room temperature (°C/°F), and the right column 

displays the dew point (Td).

The temperature can be displayed either in Fahrenheit or Celsius by 

adjusting the °C/°F switch on the back of the unit. The audio alarm can 

be activated using the “Al On / Al Off” switch on the back of the unit.

Risk of mold formation occurs at humidity levels exceeding 65%. When 

this point is reached, the frowning face icon on the display will light up. 

If the audio alarm is activated, it will also sound. An arrow pointing up 

will be flashing next to the relative humidity display. The audio alarm 

can be silenced by pressing any button.

When humidity levels are reduced below 65% the frowning face icon 

will stop flashing and the alarm (if activated) will be silenced. The arrow 

pointing up display will persist to indicate high humidity levels have 

occured in the past. The arrow pointing up display can be reset by 

pressing any button.
