Summertime: ± 1 hour
Europe: Factory set
SPECIAL: The switchover to/from
summertime can be freely programmed by entering a start date and
end date and is then executed each year on the same day of the
week, e.g. Sunday
3Programming
A program consists of an ON time, OFF time and associated on and off days.
Programs with predefined on/off days (Mon to Sun, Mon to Fri and Sat and Sun): for these programs, you only need to set the switching times.
With the „INDIVIDUAL” option, you can allocate switching times to specific days of your choice.
The programs of a channel are combined with a logical OR.

CHRONO = All switch commands are executed in chronological order in a week

Example
Expert mode

Some additional functions are available in Expert mode:
• Power grid synchronisation to improve the accuracy
• Cycle function
Note: Upon switching from ACTIVE to PASSIVE the additional menu items are hidden again and all the Expert mode settings are cancelled.
After re-activating, Expert mode will operate again with the basic settings.
Holiday

After activation the holiday program is executed between 0:00h on the start date and 24:00h on the end date (Constant ON/OFF). After the holi-
day program has run once, it must be reactivated.
Activating and deactivating grid synchronisation
Only available in EXPERT mode.
The default setting is PASSIVE. In order to improve the long-term accuracy, it is advisable to activate synchronisation if the time switch is
supplied from a on 50/60 Hz grid with frequency adjustment.


Cycle function
Only available in EXPERT mode
For cyclical switch commands the switching on time is set by logical “OR“ of programs of all types. A fixed cycle of ON and OFF time then ope-
rates within those limits. The cycle always starts with the ON time.
The cycle duration and the ON time within the cycle are the same length for all switching times. The cycle duration and the ON time can be set
independently in one-second increments. If the switching time is shorter than the cycle duration, the cycle will be shortened accordingly. The
ON time will remain unchanged. If the switching time is actually shorter than the ON time, the ON time will be shortened accordingly.
