5.6 Hygrostat control
The air dryers of the AD-series dispose of a hygrostat for setting the required
humidity value. This hygrostat is located in the operation panel. It makes that the air
dryer cuts in as soon as the ambient humidity exceeds the preset value. If the
humidity value falls below the set value, the hygrostat will switch off the unit.
