Program mode (daily)
In this mode it is possible to set the “pattern” of time segments, which define the ON time of the 11-14
output contact. This “pattern” will be the same for all days of the week (daily).
Entering Programming mode (from Display mode) with a short press to takes the digital time to
00:00 (and any previously programmed segment pattern is displayed). Stepping backwards or
forwards in time displays the appropriate segment time and the appropriate open or closed contact
status for that time segment.
At any step it is possible to change the segment status with a short press to the joystick (for ON) or
(for OFF) as appropriate, and this also automatically advances the time to the next segment, and
always in a clockwise direction. If the joystick is pressed several times in, say, the direction then
each successive segment will assume the ON status. If it is then pressed several times in the
direction then each successive segment will assume the OFF status. This allows the rapid setting of
many consecutive segments with the same status.
A short press to the joystick centre will restore the display to the Display mode.
Program mode (weekly)
In this mode it is possible to set a different “pattern” of time segments for each day of the week (weekly).
Entering Programming mode (from Display mode) with a short press to takes the display to the
programming mode, for the current day. With a subsequent short press to or it is possible to pass
from one day to another (Monday is day 1).
With the desired day selected it is possible to enter the programming mode for that day by pressing .
Program the segments for that day by following the same procedure as described above for daily mode.
When all 48 segments have been set, accept with a short press to . Then progress to the next day by
pressing the joystick in the or direction. Repeat programming for the next day, and then repeat for
other remaining days.
At any time return to the Display mode with a short press to the joystick centre .
COPY FUNCTION
View the particular day to be copied (using or as described above) and copy with a short press to
(the “copy icon” will then appear).
Then select another day, using or , and paste the copied program with a short press to .
This can be repeated for other days.
A short press to the joystick centre , or , will exit the copy function.
Power-save mode
If the 230 V AC supply is not connected, the time switch enters power-save mode: only the clock is
maintained active whilst the display turns off so as to guarantee a long life for the built-in back-up
battery.
With a press to the joystick it is possible to “awake” the device and enter Display mode (with the “plug”
symbol displayed). A further press to will enter the program or set-up mode as explained in the
Display mode section above.
After about 1 minute of inactivity the power-save mode will start again. During program or set-up the
current absorption is higher than in power-save mode, thus influencing the battery life.
In this mode the display back-light is not active. It is activated following a press to the joystick only with
the 230 V AC supply connected, but after about 1 minute of inactivity the display back-light will turn off,
and to activate it again it is necessary to press the joystick again.
