17. Humidification / dehumidification system
The cabinet is equipped with a capacitive humidity sensor. This results in a control accuracy of up to +/- 3
% r.H. of the set point.
Temperature and humidity control were optimized to a working point 21 °C /
69.8 °F
and 65% r.H.
The temperature-humidity diagrams below show the possible working ranges for humidity.
•
In the “setpoints” menu you can turn humidity control (humidification and dehumidification) on or off
with the setting “Control on/off” (chap. 6.3).
With humidity control turned off, the humidification module cools down. After activation it will take up to
20 minutes until the humidification function is fully available again. This setting is required when
operating the cabinet without a water connection in order to avoid humidity alarms.
•
Operation line “Humidity off” serves to turn off the humidification / dehumidification system in Fixed
value operation (chap. 7.3, time program operation (chap. 9.7.3) and week program operation (chap.
10.6.5). This allows configuring the disconnection for individual program sections.
When the humidification / dehumidification system is turned off via operation line it remain on standby
(filled and heated). Therefore it is immediately available after turning on.
The preset temperature and humidity values should be situated within the optimum range
(hatched range in the diagram below). Only within this area will the cabinet not be exposed to
excessive moisture due to condensation.
In the short-term set points outside the optimum range can also be targeted. The control accu-
racies of +/- 3 % r.H., however, cannot be guaranteed in this case.
