MDEH1

•  Rotary dial Dehumidistat
•  Multiple units can be used
•  We recommend setting the relative humidity above 80% 

during the summer

To avoid window condensation:  
•   It is not necessary to change 

the humidity control every 
day. Monitor the average 
weekly temperature or 
experiment with various 
settings until you find a level 
that is comfortable for you. 
Adjust the control when 
needed.

• 

   A dehumidistat is ideal for 

use in energy efficient 
houses where indoor 
humidity (during the 
heating season) is higher 
than outdoor levels. High 
humidity is a major cause 
of structure damage and 
IAQ problems such as mold 
and mildew.

*Maintain polarity
