3.3.1 Humidification
Climate/ Humidity/ Setpoints/ Humidification
Humidification increases the air humidity of the house by supplying atomized water to the air. It is important to
maintain certain air humidity, among other things to prevent dehydration of the animals’ mucous membranes.
DOL 53X increases humidification as long as the air humidity is below the Humidification setpoint.
Example 11: Humidity and humidification setpoint
Humidification/ ventilation %
When the inside temperature is below the Temperature setpoint, DOL 53X is factory preset to limit humidification.
Humidification will be disconnected if the inside temperature is 1° C below the Temperature setpoint. Humidification
could otherwise make the inside temperature drop further.
3.3.2 Humidity Control
If you want to regulate the relative air humidity in the house, you can either increase or decrease the ventilation
level, or increase or decrease the heat supply.
The warmer it is, the more water vapour can be contained in the air. The relative humidity will therefore fall
when the temperature rises, and conversely will rise when the temperature falls. For each 1°C the temperature
falls, the air humidity will increase by 5%. If the temperature falls so much that the relative air humidity
reaches 100%, the water vapour will start to condense (dew point).
Climate/ Humidity/ Active
When humidity control is disconnected, DOL 53X regulates ventilation
according to the inside temperature alone.
