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

Overview of operating and control elements
ON/OFF switch
The ON/OFF switch (2) is located to the side of the switchbox and above the mains plug (1,
see fi gure):
◊ If it is set to 0, the power supply is disconnected and the dryer is switched off. The expan-
sion valves are normally closed.
◊ If the switch is set to I, the dryer is switched
on and begins to operate in fi xed cycle mode
(i.e. time-controlled).
◊ If the switch is set to position II, the dryer is
switched on and begins to operate
— with compressor synchronisation
— in variable cycle mode (i.e. dew-point-cont-
rolled).
Position II is only relevant for operation with
the optional compressor synchronisation and/
or dewpoint-sensing control
