Reset
Simultaneously pressing all buttons for more than 2 seconds deletes all
data. Language, date/time, summer time (daylight saving time) and
switch times must be set again.
Data key
If the supply voltage is switched on, the "KEY – READ – WRITE" menu
item is automatically opened when a data key is inserted. "WRITE":
Program data is written from the time switch to the key. Caution: Any data
present on the key will be overwritten. "READ": Program data is written
from the key to the time switch; any switching programs on the time switch
are overwritten. Only one master switching program, which consists of
multiple switching programs, can be saved on the time switch or on the
key at a time. If the supply voltage is not connected, the "KEY – READ
– WRITE" menu item is not automatically opened when a data key is
inserted. The "KEY" function can still be selected from the
menu even if the supply voltage is not connected.
PC programming
In addition to the easy, text-guided programming directly on
the time switch, switching programs can also be created on a
PC with the software program from Legrand and transferred to the time
switch using a data key. A data transfer device (Cat.No : 4128 73) is
required to transfer switching programs created on a PC to the data
key. The device is connected to the PC using the USB plug. In addition
to the data transfer device, we also o er a CD with the software and the
necessary drivers. PC system requirements: USB port;
