Chapter 12 Humidity control
Humidity control can be configured as Humidification, Dehumidification or both Humidification and
Dehumidification.
Two humidity sensors can be connected, a room sensor for control and an optional duct sensor for
maximum limiting. The limit sensor can be omitted.
The humidity control is handled by a PI-controller.
The humidity sensors must give 0…10 V DC for 0…100 % RH.
Humidity sensor room
Humidity room
Actual: 51.9% RH
Setp: 50.0% RH
Humidity sensor duct
Humidity duct
Actual: 72.2% RH
Max limit: 80.0% RH
Hyst: 20.0% RH
If the maximum limitation is 80 % RH and the hysteresis is 20 % RH, the controller output signal will
begin decreasing at 60 % RH. When halfway to 80 % RH (i.e. when at 70 % RH), half the output
signal will be damped. If the humidity in the duct still reaches 80 % RH, the entire output signal will
be damped.
