The time switch switches on at the calculated sunset time and off at
the calculated sunrise time.
By setting an offset, you can shift the switching times by up to ±120
minutes with respect to the calculated sunrise and sunset times.
Example: If you set the offset to +30 minutes, the time switch will
switch 30 minutes after sunrise and 30 minutes after
sunset. If you set the offset to -30 minutes, the time
switch will switch 30 minutes before sunrise and 30

PROGRAM / WEEK
This menu item is provided for the simple input of programs which are to be repeated weekly (such as switching of lights and boilers).
A weekly program consists of an ON time, an OFF time and the associated ON and OFF days.
• MON TO SUN: the days of the week are already assigned and you only need to set the ON and OFF times.
This is used where the same program is to be executed on every day of the week.
• INDIVIDUAL: you can assign the ON and OFF times to any desired days. This is used where the same
program is to be executed only on certain days of the week or different programs are to be executed on
the various days.

PROGRAM / YEAR
This menu item permits the input of (additional) annual programs which are to be executed only during a
specified period. These programs and the weekly programs of the same channel are ORed together as
described above.
The period during which a program is to be executed is defined by entering a start date and an end date.
• The option EVERY YEAR should be selected if the additional program is to be executed during the same
period of each year (e.g. Christmas, national holidays, birthdays, etc.).
• The option ONCE should be selected if the additional program is to be executed only during a single
period (e.g. vacation period), but the start and end dates of this period are different in each year.
• The option MOVABLE should be selected if additional switching times are to be performed on movable
public holidays/special days. (e.g. Easter, Whitsun, etc.). Entry is always for the current year. In the years
that follow, the switch always takes place on the selected movable public holidays/special days.
Default is Easter Sunday of the current year. →

PROGRAM / EXCEPTION
The weekly and annual programs defined are not executed as long as an extra program is active.
However, other exception programs will be executed while an exception program is active.
The various exception programs are ORed together as described above. (see OR function 3a)
• The option EVERY YEAR should be selected if the exception program is to be activated for the same
period in each year (e.g. Christmas, national holidays, birthdays, etc.).
• The option ONCE should be selected if the exception program is to be activated only during a single
period (e.g. vacation period), but the start and end dates of this period are different in each year.
The option MOVABLE should be selected if additional switching times are to be performed on movable
public holidays/special days. (e.g. Easter, Whitsun, etc.). Entry is always for the current year. In the years
that follow, the switch always takes place on the selected movable public holidays/special days.
Default is Easter Sunday of the current year. → 3D
• Option MON TO SUN: the exception program is active from 00:00 hours on the start date to 24:00 hours
on the end date. During this period, the time switch switches only as defined in the exception program.
• Option INDIVIDUAL: the exception program is active from 00:00 hours on the start date to 24:00 hours on
the end date. During this period, the switching is only as only as defined in the exception program.
• Option PROG ON: the exception program is active from the ON time on the start date to OFF time on the
end date. During this period, the output is permanently on.
• Option PROG OFF: the exception program is active from the ON time on the start date to OFF time on the

Movable public holidays/special days
3D
The clock calculates movable public holidays which are dependent on the liturgical* Easter date according
to the rule of Gauß and therefore takes into account the annual shift of the Easter date. The movable
public holidays align with the shift; they are always realised with
a certain number of differential days to Easter.
* Note: In some years, there is a difference between the liturgical and orthodox Easter date.

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.
Page 28
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 operates 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.

On each day during a specific period of a specified year, an exception
program is to completely replace any existing weekly or annual program.
Example: during the Christmas holidays of the year 2012, the heating
in an apartment is to be switched each day from 7:00:00 to 23:00:00,
instead of in the normal cycle. This exception period is to begin on 24
December 2012 and end on 06 January 2013.
On certain weekdays during a specific period of a specific year, an
exception program is to completely replace any existing weekly or annual
program.
Example: in December 2012, the heating system of a department store is
to be switched on from 8:00:00 to 18:00:00 each Sunday, because the
store opens on Sundays in the period 4 December 2012
to 18 December 2012.
A channel is to be switched on continuously from the ON time on the
START date to the OFF time on the END date of a specific year. This
exception program is to completely replace any existing weekly or annual
program for this channel.
Example: the alarm system of an office building is to be switched on continuously during the vacation period 19:00:00 on 15 July 2012 to 06:00:00
on 7 August 2012.
A channel is to be switched off continuously from the ON time on the
START date to the OFF time on the END date of a specific year. This
exception program is to completely replace any existing weekly or annual
program for this channel.
Example: in 2012, the normal recess gong in a school is to be switched
off during the summer holidays 00:00:00 on 28 July 2012 to 24:00:00 on

Et undtagelsesprogram skal hvert år erstatte et allerede
eksisterende årsprogram på en forskydelig helligdag.
F.eks. i en kirke skal belysningen tændes og slukkes
anderledes på de liturgiske helligdage end med det daglige
omskiftningsprogram.
Et undtagelsesprogram skal hvert år på tirsdagen efter
pinse udføre en omskiftningscyklus.
f.eks. skal porten til et fabriksområde ikke åbnes hvert år
på tirsdagen efter pinse.
Hvert år skal der være tændt permanent til påske. Dette
undtagelsesprogram skal helt erstatte
andre eventuelt eksisterende uge- eller årsprogrammer.
Eksempel: I modsætning til en kirkes normale, daglige
belysningstider skal lyses tændes hvert år til påske fra kl.
17:00:00 til kl. 24:00:00.
Hvert år skal der permanent slukkes fra tændingstidspunktet på startdatoen til slukningstidspunktet på slutdatoen.
Dette undtagelsesprogram skal inden for datointervallet
helt erstatte andre eventuelt eksisterende uge- eller årsprogrammer.
Eksempel: Energiforsyningen til bestemte anlæg i en
virksomhed skal i stedet for det normale forløb slukkes kl.
6:00:00 i påskeferien hvert år.
