Setting times of the operating phases
In its standard version the dryer is delivered with a time-dependent control system. The
phase sequence occurs in a fi xed cycle.
With the optional dewpoint-sensing control, the dryer can also be operated at variable cycles
(depending on the dewpoint).
The following table provides information on the duration of the individual phases
