How to use the heating to control too high humidity?



 Answer 


The setting for humidity control is: "circuit pipe minimum".
With this setting it is possible to heat up the pipes when the relative humidity (RH) is too high or the humidity deficit (HD) is too low.




Example 1: RH control



The pipes start to heat up if the relative humidity is 10% higher than the set RH (in greenhouse climate settings).
If the RH is 15% higher than the set RH the pipes are at 40 °C.

For example when the set RH is 75%

Example 2: HD control



The pipes start to heat up if the humidity deficit is 1,5 g/m3 lower than the set HD (in greenhouse climate settings).
If the HD is 2,5 g/m3 lower than the set HD the pipes are at 40 °C.

For example when the set HD is 3,5 g/m3
 measured HD (g/m3)
pipe temperature (°C)
