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 forwards or 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 programming mode, for the current day. With a subsequent short press to takes the display to the 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 pressing the joystick in the or . Then progress to the next day by 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 .

Then select another day, using or , and paste the copied program with a short press to . This can be repeated for other days. , or , will exit the copy function. Residential applications A short press to the joystick centre 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. I-2014, www.findernet.com 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. 13 12 SERIES 12 Series - Astro-Switch 16 A Functions type 12.81 All the functions and the values can be set through the joystick and are displayed on the LCD.

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): - country (using Internet websites extension, e.g. IT, DE, FR..) - post-code (CP, setting only the first 2 digits, 00 to 99 - or letters for UK) - current year - current day - current month - current hour - current minute - enable/disable european summer time.

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. The Override feature permits the 12.81 three different ASTRO ON ASTRO OFF ways of functioning: 1 Classic function where the AstroON and AstroOFF times are determined by the geographic coordinates. These times vary every day. 2 1 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 I-2014, www.findernet.com *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. 3 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 Residential applications 2 3 at 00:30 . and off automatically by AstroOFF*. 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. 15
