Using Humidity Control - Dräger 8000 IC Instructions For Use Manual

Using humidity control

It is possible to control air temperature and relative
humidity in both automatic and manual modes.
In the automatic mode the set value for humidity is
calculated and adjusted automatically by the system,
depending on the air temperature set value, see
