General
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.
Humidification
An analogue output is used to control a humidifier. The output will increase on
decreasing humidity. A digital output can also be used to start a humidifier.
Maximum limitation function using duct humidity sensor:
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.
