- Clockwise: to increase run on time
- Anti-clockwise: to decrease run on time
On/Off switch unit
Units equipped with an adjustable hygrostat which can be varied from 60% to 90%
RH (Relative Humidity). The hygrostat automatically switches the unit on when the relative humidity in
the room exceeds the preset value. To adjust the required humidity level, remove the grille (1) and turn
the potenciometer (H) Fig. 6. These units also have a pull cord switch to override the hygrostat when the
humidity level is lower than the preset value.
