Functions type 12.51

All the functions and the values can be set through the joystick and are displayed on the LCD.

Display mode

During normal operation, with AC supply connected, the following is displayed:

- the current time (hours and minutes)

- the status (ON/OFF and symbol of contact open/closed) of the 11-14 output contact

- the program for the current day (each solid segment represents an half-hour interval set to ON)

From Display mode it is possible to enter in Program mode or Setup mode respectively with a short or

long (> 2s) press to the joystick centre .

Manual mode

From Display mode it is also possible to enter in Manual mode, where (independently from the program)

the 11-14 output contact can be forced into the ON or OFF position with a long (> 2s) press to the

joystick or directions, respectively. The “hand” symbol is then displayed.

A long press in the opposite direction will exit the manual mode.

Setup mode

In this mode it is possible to set (in the following order):

- daily/weekly function

- current year

- current day

- current month

- current hour

- current minute

- enable/disable european summer time.

With a short press of the joystick or , it is possible to pass from one setup step to another

(confirming the set values); in any step it is possible to modify the set values with a short press to the

joystick or . A sustained (> 1s) press results in the fast increasing (or decreasing) of values.

A short press to the joystick centre will restore the Display mode.

Note: the product is supplied factory set to Central Europe time with european summer time enabled.

12 Series - Time Switch 16 A

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.

12 Series - Astro-Switch 16 A

Program mode (advance/retard setting)

In this mode it is possible to set independently:

- the advance (or the retard) of the light turn-on time in the evening with respect to the “astronomic”

sunset time.

- the advance (or the retard) of the light turn-off time in the morning with respect to the “astronomic”

sunrise time;

From the Display mode - A short press of the joystick will display the “astronomic” sunset time,

indicated by the (clockwise) transition from to (“ON” and closed contact symbols displayed).

A short press to or will retard or advance the switch ON time about the astronomic time in

10 minute steps (up to a maximum of 90 min.).

Press to display the “astronomic” sunrise time, indicated by the (clockwise) transition from to

(“OFF” and open contact symbols displayed). Again, a short press to or will retard or

advance the switch OFF time about the “astronomic” time, in 10 minute steps.

At this point, either exit (to Display mode) with a short press to , or continue to set the Astro ON

period override time(s) with a short press to .

Set the OFF time using or . A further short press to will display the ON time which again

can be set using or .

Note: setting “--:--“ for either OFF or ON means the function is inoperative.

Continuing to press will cycle through the “sunset” / “sunrise” / “OFF” / “ON” settings in turn.

A short press to at any time will return the display to Display mode.

Note 1: The effect of the retard/advance settings is valid for all days. That is; lights will, for example,

always turn-on every day for 30 minutes before the “astronomic” sunset time.

Note 2: The effect of the On period override settings is also valid for all days - but also see Note 3 by

the function diagrams.

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.

Note: the output relay only functions if the power supply is connected.

ASTRO

OFF

The Override feature permits the 12.81 three different

ways of functioning:

Classic function where the AstroON and AstroOFF

times are determined by the geographic coordinates.

These times vary every day.

Functions such that the output turns on according to

the AstroON time and turns off according to the clock

off-time . Application example: shop window

lighting on by AstroON at sunset and off at

00:30 .

Functions such that the output turns on according to

the AstroON time and turns off according to the clock

off-time , and then turns back on at the clock

on-time (for the remainder of the ASTRO time

period). Application example: company car park

lighting, on by AstroON at sunset, off end of the

evening shift at 23:00 . On again at the

beginning of the morning shift at 5:00 and

off automatically by AstroOFF*.

*Note 3: Depending on the time of year (summer

specifically) it may be that the override

ON time will fall after the AstroOFF time.

In this case, the output switches off at the

Astro OFF time and the override ON

time is ignored.
