Humidity control Select the type of humidity control
Humidity cut-in Set-point for the humidity control.
At humidifier control, the humidifier is started when
the humidity has dropped to the set-point.
At dehumidifier control, the dehumidifier is stopped,
when the humidity has dropped to the set-point
Humidity differen- Differential for humidity control.
tial At humidifier control, the humidifier is stopped when
the humidity has increased with the set differential
above the set-point.
At dehumidifier control, the dehumidifier is started,
when the humidity has increased with the set differ-
ential above the set-point
