A first setup wizard will guide you through the initial configuration after inserting the battery or after connecting to the power supply.

Each channel can be assigned a different 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 devices 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 offset (deviation) function, the turning ON and switching OFF times can be corrected within ± 120 minutes. The delay is fixed for each day but can be adjusted for each channel separately.

· Operation modes of switching: (configurable for each channel separately)

–

(switches according to set holidays, astronomi-

cal and time program)

–

(switches randomly in an interval of 10-120 min)

–

(fixed 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 off 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 memory 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.

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/off by
long press of MAN1, MAN2, and OK buttons at the same time. When activating /
deactivating the permanent backlight, the display will briefly flash twice.
Backup mode: In the event of a power failure, the display will automatically
switch to sleep mode, during which time only the following will flash 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
significantly increased, which affects its service life. It will return to
sleep mode if no buttons are pressed for 20 seconds.

We have two types of manual controls available:

· Permanent (symbol glows)

The second highest priority of all control modes. The state of the output
cannot then be

changed other than by manual change (e.g. by switching to temporary manual
control

or by activating mode

, which has a higher priority). The last option is to

deactivate this control mode.

· Temporary (symbol flashing) Temporary manual control has the same priority
as the previous, permanent one. However, it can be changed in the future,
unlike permanent manual control, by one of the programs with a lower priority
(if configured in the time switch). With power supply disconnection, temporary
manual control is deactivated.

Wi-Fi connection  
First, make sure that you have a configuration device (PC/phone/…) with Wi-Fi
of 2.4 GHz band that supports a web browser and is close enough to SHT-13 that
you want to connect. The time switch does not support a 5 GHz band.  
It is possible to connect directly to the web server for configuration via the
Wi-Fi generated by the SHT-13 (no router or internet connection required). If
the time is to be synchronized, an internet connection via a Wi-Fi router is
necessary.  
Activating the Wi-Fi of time switch: After connecting the SHT-13 to the power
supply, it is possible to activate/deactivate Wi-Fi by briefly pressing the OK
button. If Wi-Fi is active and the configuration device is not connected, it
will automatically turn off after 90 seconds.  
NOTE.: Wi-Fi can be activated permanently through the settings, once the setup
wizard is complete

: Now connect your configuration device to the Wi-Fi of the time switch
(follow the instructions provided by the manufacturer of the configuration
device).  
SHT-13 Wi-Fi access data (default): SSID hostname: SHT-13_barcode number

minutes supply voltage from the mains. When the supply voltage is
disconnected, time data

are saved for 30 seconds, during which you replace the battery, continue with
step #3.

You can replace the battery in a user-friendly way, without disassembling the
device, with the mains voltage on or off. When replacing the battery, note
that terminal A2, 26, 25, 28 may be under voltage.  
When replacing the battery, the following three situations may occur: a. The
timer is connected to the mains supply = proceed according to steps #3 ­ 6. b.
The timer is not connected to the mains supply (battery supply) = proceed
according to steps #1 ­ 6 c. The timer is connected to the mains supply with a
discharged battery = proceed according to steps #2 – 6

NOTE: It is good to physically insert a new battery when the 30 second
replacement interval is running out, in order to minimize the deviation of the
set time.  
3\. slide out the plug-in module with the battery 4. remove the original
battery 5. insert the new battery so that the upper edge of the battery (+) is
aligned with the plug-in  
module 6. insert the plug-in module as far as it will go into the device – pay
attention to the polarity (+  
up)  
If you did it right, the battery symbol on the display will go out after the
replacement (if the battery is fully charged) and there will be no or only a
minimal deviation in the time data. To achieve repeated and long-term running
accuracy, use time synchronization via a Wi-Fi connection – see the Wi-Fi
connection section.

· Factory reset: It is performed by long pressing <5 with a blunt tip of the
hidden RESET button (e.g. a pen or a screwdriver with a diameter of max. 2
mm). The display briefly shows all display segments, then the device type and
firmware version. The following is a setup guide – i.e. the same state in
which you received the timer from the factory. Settings and all configured
programs/holidays are erased by this step.  
· Restart: It is done by briefly pressing <1 with the blunt tip of the hidden
RESET button. The display briefly shows all display segments, then the device
type and firmware version. This is followed by a transition to the main screen
– date, time, program activity, contact status, etc. This step will not result
in the loss of settings or configured programs/holidays.
