Programming
A program consists of an ON time, an OFF time and the associated
ON and OFF days.
If you select "MON TO SUN" (Monday to Sunday), the days are
already assigned and you only need to set the ON and OFF times.
If you select "INDIVIDUAL", you can assign the ON and OFF times
to any desired days.
The programs are linked
to one another by logical OR.

C HRONO = the switching times
are indicated in

during the week.
INPUT = programs are indicated in the order in which they are entered.
Programming examples
The timer is to switch on at sunset on each day of the week and
switch off at sunrise.
The timer is to switch on at sunset on each day of the week and switch off at sunrise. In addition, it is to be switched off each night
between 23:00h and 5:00h. This requires the use of two programs.
Program 1: ON at sunset and OFF at 23:00h
Program 2: ON at 5:00h and OFF at sunrise.

Data key
or
• Load the programs of the time switch on to a data key (WRITE KEY)
Warning! all programs already existing on the data key will be overwritten.

Warning! all programs already programmed in the time switch will be overwritten.
1 h-test
When this function is activated, the outputs are switched on for one hour.
After one hour, the time switch returns automatically to the programmed mode.
Pincode (access protection)
A reset cancels any existing access protection.
Control input with delaytime
A control signal overrides all program settings (OR function). The output is switched on as long as the control signal is present.
When the control signal is switched off, the output is switched off after the programmed delaytime has elapsed, unless it is switched on by any
program. The control signal must be present at the control input for >100ms to initiate a switching command.
Setting the delaytime
0min ... 23h 59min
Operating-hours counter
This displays the total duration of the
ON times, from 0 to 65535 hours, and
the date on which this counter was
last reset.
Reset
Note!
A reset clears the entire memory,
which means that all previously set data will
be lost.
Press and hold all four keys together for
about 2 seconds, then release them.
After a reset, the language, time and date,
summertime, coordinates, time zone,
switching times and pin code must be set again.
