General information• Start-up: after applying the supply voltage, the time switch starts automatically with the last selected function. The relay position is set by the current program.• Battery backup - Backlighting not active - Data key READ/WRITE only via the menu• For saftety, when the time switch is connected to the mains supply the contact should not be used on an isolated low voltage supply and when the time switch is connected to the isolated voltage supply the contact should not be used on the mains supply.

Correction

The time switch switches on at the calculated sunset time and off at the calculated sunrise time.By setting an offset, you can shift the switching times by up to ±120 minutes with respect to the calculated sunrise and sunset times.Example: If you set the offset to +30 minutes, the time switch will switch 30 minutes after sunrise and 30 minutes after sunset. If you set the offset to -30 minutes, the time switch will switch 30 minutes before sunrise and 30 minutes before sunset.

3Programming

A program consists of an ON time, an OFF time and the associated ON and OFF days.If you select „MON TO SUN“ (Monday to Sunday), the days are already assigned and you only need to set the ON and OFF times.If you select „INDIVIDUAL“, you can assign the ON and OFF times to any desired days.The programs are linked to one another by logical OR.

*

*CHRONO = the switching times are indicated in chronological order during the week.INPUT = programs are indicated in the order in which they are entered.

Programming examples

The timer is to switch on at sunset on each day of the week and switch off at sunrise. In addition, it is to be switched off each night between 23:00h and 5:00h. This requires the use of two programs.Program 1: ON at sunset and OFF at 23:00hProgram 2: ON at 5:00h and OFF at sunrise.

b

a The timer is to switch on at sunset on each day of the week and switch off at sunrise.

Modes

• Auto - Automatic operation• Constant ON• Constant OFF• Extra The switch status imposed by the program is inverted (manual override). With the next effective switch command, the time switch resumes control of ON/OFF switching.

Warning! The memory will be cleared, and all set data will be lost.

Hold down for more than 3 seconds and at the same time press and release

When this function is activated, the output is switched ON for one hour.

After one hour, the time switch returns automatically to the programmed mode.

Hour counter

Displays the total relay ON time (0 to 65535 h) and the date of the last reset.

Random function

Function to simulate presence.Function active: the programmed switching cycles are shifted at random within the range of ± 15 minutes.

Expert modeSome additional functions are available in Expert mode:• Power grid synchronisation to improve the accuracy • Cycle function • Summer / winter seasonal correction• Automatic channel switching

Note: Upon switching from ACTIVE to PASSIVE the additional menu items are hidden again and all the Expert mode settings are cancelled. After re-activating, Expert mode will operate again with the basic settings.

Activating and deactivating grid synchronisation

Only available in EXPERT mode.The default setting is PASSIVE. In order to improve the long-term accuracy, it is advisable to activate synchronisation if the time switch is supplied from a on 50/60 Hz grid with frequency adjustment.

Pincode

PIN CODE active: The menus of the time switch will not be accessible unless the PIN CODE has been entered. When the pin code is active, access to the button and key functions is disabled 1 minute after the last button press.PIN free access can be re-enabled by selecting PASSIVE or by resetting the device.

Example

HolidaysAfter activation the holiday program is executed between 0:00h on the start date and 24:00h on the end date (Constant ON/OFF). After the holiday program has run once, it must be reactivated.

Cycle functionOnly available in EXPERT mode

For cyclical switch commands the switching on time is set by logical “OR“ of programs of all types. A fixed cycle of ON and OFF time then ope-rates within those limits. The cycle always starts with the ON time.The cycle duration and the ON time within the cycle have the same length for all switching times. The cycle duration and the ON time can be set independently in one-second increments. If the switching time is shorter than the cycle duration, the cycle will be shortened accordingly. The ON time will remain unchanged. If the switching time is actually shorter than the ON time, the ON time will be shortened accordingly.

Automatic channel switching Only available in EXPERT mode

On two-channel time switches a cyclic switch between channels can be set to conserve and/or ensure even use of connected equipment such as lamps and lights. For example, with two sets of lights, one can be used all night long and the other for part of the night only. However, cyclical inversion of the outputs ensures that the lamps are on for the same length of time on average.The outputs are automatically swapped over once a day (12 noon) or once a week (Sunday at 12 noon).
