The humidity adjusted at the hygrostat does not become achieved and/or the 

device does not switch off automatic.

- Is the hygrostat adjusted on a value lower than 40 – 45% r.h.? Humidity values  

with a minimum of 40 % - 45 % r.h. can be achieved with a condensation dryer. 
Adjust the hygrostat to a reachable value. 

-  Is the unit with enough capacity for your application? The air changing, number of 

the persons in the room and open water surfaces decide on the humidity burden 
in the room. Let calculate the necessary capacity from your dealer 

-  Is there a lot of water in the walls or the floor? In that case the dryer needs some 

time to remove that water and to achieve an acceptable humidity in that room.
