Characteristics
• All programs in one device (daily, weekly, yearly and astronomical).
• UNIversal supply voltage in range of AC 110 – 230 V (50-60 Hz).
• Simple setting after the first start-up.
• Integrated super capacitor to back up the set time during power outages.
• Built-in web server for setup and control via Wi-Fi connection.
• Time synchronization through NTP server (require internet connection of time
switches).
• Possibility of permanent connection to the local network.
• WRC: web remote control and setup from anywhere (require internet connection
of time switches).
• Withou display in 1-module housing.
• ASTROnomic program: manual entry of coordinates or selecting from one
of more then 500 preset cities.
- selection of days of the week
- astro interrupt function (night break): controls the sunrise/sunset times and
compares them with the set OFF/ON times
- high position accuracy thanks to two decimal places in latitude/logitude
• 1-channel design (with an operating hours counter).
• Pulse/cycle output mode.
• Transition of summer/winter time – AUTO or OFF.
• PIN code protection against unauthorized changes.
• Wireless firmware update - current version 1.59
After connecting the product to the power supply and pairing Wi-Fi with the confi -
guration device, you will be guided through the initial setup after opening the web
interface.
In the event of a power outage, the device will retain all the set values required for
reliable switching after the power is restored (max. duration is 30 h). 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 off times of e.g. public lighting. This is because the sunrise and sunset times
change throughout the year. With the off set (deviation) function, the turning ON and
switching OFF times can be corrected within ± 300 minutes. The off set is fi xed for
each day.
• Operation modes of switching:
- (switches according to set time programs)
- (switches according to set holidays and time programs
- (switches according to the set astronomical and time pro-
gram)
-
cal and time program)
- (switches randomly in an interval of 10-120 min)
- (fi xed output state that cannot be changed other than through
settings)
• Possibility to manually control the output contact at any time (outside the operati-
on mode, ).
• The time switch can work in CLIENT and AP wireless communication mode inde-
pendently of each other.
• 200 memory locations for time programs.
• Up to 30 memory locations for holidays.
• Optional languages – CZ / EN / SK / HU / PL / ES / DE / BG / RU / UA / HR / SLO / RS
• Selection of summer/winter time transition:
- AUTO (changes automatically according to the entered time zone)
- OFF (permanently switched off winter/summer time transition)
• The time switch is equipped with a supercapacitor, which backs up the set time
during a power outage. All settings and programs are saved in memory in the
event of a power outage - they can thus be restored even in the event of a power
outage together with a discharged capacitor. However, a time correction will need
to be made.

BEHAVIOR UNDER VOLTAGE AND IN SLEEP MODE
Under voltage: The time switch indication is active, with a steady green LED indicating the
presence of supply voltage. A red LED shows the state of the output contact or the type of
manual control.
Sleep Mode: In the event of a power outage, the time switch goes into sleeping mode. In
this state, the set time is backed up for a maximum of 30 h. The LEDs do not indicate the
presence of supply voltage or the state of the output contact.

NTP TIME SYNCHRONIZATION
If NTP synchronization or client connection was previously confi gured through the web
interface, the NTP synchronization can be launched on SHT-14 by pressing SET button (> 5 s).
The green and red LEDs fl ash 3× alternately.
