Manual Corrigo Ventilation, revision R Chapter 12 Humidity control 65Chapter 12 Humidity controlHumidity control can be configured as Humidification, Dehumidification or both Humidificationand Dehumidification.Two humidity sensors can be connected, a room sensor for control and an optional duct sensor formaximum 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 roomHumidity roomActual: 51.9% RHSetp: 50.0% RHHumidity sensor ductHumidity ductActual: 72.2% RHMax limit: 80.0% RHHyst.: 20.0% RHIf the maximum limitation is 80 % RH and the hysteresis is 20 % RH, the controller output signalwill begin decreasing at 60 % RH. When halfway to 80 % RH (i.e. when at 70 % RH), half theoutput signal will be damped. If the humidity in the duct still reaches 80 % RH, the entire outputsignal will be damped.
