Setting/programming the switching times
4
Switch between manual, automatic or holiday mode
Press the button briefly to set the current time. The sym-
bol flashes on the LCD display (Fig. 4). The current time
can now be adjusted using the
and
buttons.
The time that has been set is saved by pressing the but-
ton again. At the same time, the day of the week (Fig. 5)
will appear on the display (this is the setting mode for the
day of the week). You now decide whether the timer is to
be operated using a daily or weekly program.
Daily program:
If the timer is to operate at the same times every day,
press the button again. The U26 then does not save the
current day of the week, and executes the programmed
switching times for UP and DOWN every day.
Switching times of 7.00 a.m (for UP) and 8.00 p.m. (for
DOWN) are factory programmed. To change these swit-
ching times, briefly press the "P" button. The display now
shows the switching time for the UP command (Fig. 6).
This switching time can be changed using the
and
buttons. Press the "P" button again briefly to change the
switching time for the DOWN command. The display now
shows the switching time for the DOWN command (Fig. 6).
This switching time can again be changed using the
and
buttons.
If the U26 is being operated in the
daily program
, then
when the "P" button is pressed again, the display changes
to the current time. The changed switching times are sa-
ved at the same time.
If the U26 is being operated in the
weekly program
, the
time jumps to the UP command for the following day.
Through repeatedly pressing the "P" button, the switching
times for each weekday are called up, and can again be
changed using the
and
buttons. Finally, after day 7,
you return to the display of the current time. The changed
switching times are saved at the same time.
If the roller shutter being operated is not to carry out an UP
command on one day, delete the displayed value by pres-
sing the button;
appears on the display (Fig. 7).
Press the Manual/Auto/Holiday mode button. The current
mode is indicated on the display.
Automatic mode:
The UP and DOWN commands that have been set are ex-
ecuted. If the sun and twilight sensor is used, the sun and
twilight functions are executed. Manual operation is also
possible at any time (Fig. 8).
Manual mode:
The UP and DOWN commands that have been set are not
executed.
Note
If the sun and twilight sensor is used, the sun and
twilight functions are not executed. Manual opera-
tion is nevertheless possible at any time.
Weekly program:
If the timer is to switch at different times each
day, set the current day of the week now by ap-
propriately pressing the
and
buttons
(e.g.: number 1 for Monday).
Now press the button again. The U26 saves the day of
the week that has been set, and executes the switching
times programmed for each day.
If you want to change from the weekly program to the dai-
ly program, select the day of the week by pressing the
button twice. Now press the
button until all the numbers
(1-7) are shown on the display. Confirm the new setting by
pressing the button.
Offset function:
The offset function moves all the programmed switching
times, separated according to opening and closing time,
by a certain amount all at once. This allows the times se-
lected in the weekly program to be adjusted easily to the
seasonal changes in sunrise and sunset. This is how it is
done:
Press the "P" button for at least 3 seconds. "
" ap-
pears on the display. Now use the
and
buttons to en-
ter the period of time by which you want to shift the times
currently programmed for the UP commands. Negative
values shift the switching time to an earlier moment, posi-
tive values to a later moment.
Confirm your input by pressing the "P" button once. Now
enter the period of time by which you want to shift all the
programmed DOWN commands. Again acknowledge the
input by pressing the "P" button.
Reset:
All the programmed values are deleted by pressing the
Reset button. The program is restarted, and adopts the
specified standard values.
Holiday mode:
In this mode, the set switching times are operated with a
randomly generated delay of between 1 and 31 minutes.
The resulting irregularity of the switching commands simu-
lates an occupied house. Here again, manual operation is
possible at any time, and if the sun and twilight sensor is
used, the sun and twilight function is executed.
