11.1| Control sequences
Parameter U01 is used to enable humidity control and defines the probe used for control, i.e. supply humidity “SHU
– Sup. Humidity” (U01=SUP) and return “RHU – Ret. Humidity” (U01=REt).
The humidification and dehumidification process is controlled by the selected probe with PID logic based on the
following setpoint: minimum setpoint HUM, maximum setpoint DEH.

11.2| Humidifier control
The software can handle both ON/OFF and modulating humidifiers, respectively using the digital output “HUM
– Humidifier” and the analog output “HUA – Humidifier”.
Is possible to manage also a pump with the digital output “HUP – HumidPump”.
