DISPLAY BACKLIGHT CONTROL
Powered: By default, the display is backlit for 90 seconds from the time of the last press of
any button. The display still shows: the date, time, day of the week, state of contacts, and
battery or the type of program in progress. The backlight is permanently switched on/o
by long press of MAN1, MAN2, and OK buttons at the same time. When activating / deacti-
vating the permanent backlight, the display will briey ash twice.
Backup mode: In the event of a power failure, the display will automatically switch to sle-
ep mode, during which time only the following will ash on the display: the date, time,
day of the week, and battery state. The time switch can then be woken up at any time by
pressing the OK button to the standard mode, e.g. for setting (without working Wi-Fi or
output contacts) - however, take into account that in this case the consumption from the
battery is signicantly increased, which aects its service life. It will return to sleep mode if
no buttons are pressed for 20 seconds.
A rst setup wizard will guide you through the initial conguration after inserting the
battery or after connecting to the power supply.
Each channel can be assigned a dierent program or operating switching mode, this
allows control of two independent circuits. In the event of a mains power failure, the
device will retain all the set values required for reliable switching after the power is
restored. After installation, it does not require any special service or maintenance.
The astronomical program does not need any optical sensors or other external de-
vices to function. Its operating principle is that during the year every day, based on
an algorithm and real-time (set in the time switch), automatically controls switching
on and o times of e.g. public lighting. This is because the sunrise and sunset times
change throughout the year. With the oset (deviation) function, the turning ON and
switching OFF times can be corrected within ± 120 minutes. The delay is xed for
each day but can be adjusted for each channel separately.
• Operation modes of switching: (congurable for each channel separately)
-(switches according to set time programs)
-(switches according to set holidays and time programs
-(switches according to the set astronomical and time pro-
gram)
-(switches according to set holidays, astronomi-
cal and time program)
-(switches randomly in an interval of 10-120 min)
-(xed output state that cannot be changed other than through
settings)
• Possibility to manually control the output contacts at any time (outside the opera-
tion mode, ).
• 200 memory locations for time programs (common for both channels).
• Up to 30 memory locations for holidays
• Programming can be done under power and in backup mode.
• Optional languages – CZ / EN
• Selection of summer/winter time transition:
- AUTO (changes automatically according to the entered time zone)
- OFF (permanently switched o winter/summer time transition)
• The time switch is backed up by a battery, which enables it to operate in backup
mode in the event of a power failure. All settings and programs are saved in me-
mory in the event of a power failure - they can thus be restored even in the event
of a power failure and a discharged battery. However, a time correction will need
to be made.
Prescribed minimum output protection: class B circuit breaker 16A.
• All programs in one device (daily, weekly, yearly and astronomical).
• UNIversal supply voltage in range of AC/DC 24 - 240 V (AC 50-60 Hz).
• Simple setting after the rst start-up.
• User replaceable battery to back up the set time.
• Built-in web server for setup and control via Wi-Fi connection.
• Time synchronization through NTP server (require internet connection).
• New well-arranged display with white backlight.
• ASTROnomic program: manual entry of coordinates or selecting one of the preset
cities.
• One/two channel design (each with an operating hours counter).
• Pulse/cycle output mode.
• Transition of summer/winter time - AUTO or OFF.
• Lead-sealing transparent front panel cover.
• PIN code protection against unauthorized changes.
• Wireless rmware update.
