Timer with an astronomical program
Made in Czech Republic
02-23/2017 Rev.: 1
Description
Characteristics
The SHT-4 astronomic timer is used for the automatic real-time controlling of appliances. The timer
operates all year round without the need of continuous maintenance, with minimum operating costs and
maximum savings of electrical energy. (For example for turning on heating, pumps, ventilators, public
lighting etc.). Appliances can be controlled in regular time cycles or based on a pre-set programme.
The astronomic timer does not include any optical sensors or other external equipment. After installation, it
requires no special operation or maintenance. In the case of a power supply interruption, the timer retains all
set values required for its reliable activation after power is restored.
The operation of the astronomic timer is based on the variations in the sunset and sunrise times
throughout the year. Based on the current date (internal real-time clock), it automatically modifies
the times for turning on or off e.g. public lighting. Time updates are resolved automatically for every
day of the year. Using the Offset function, it is possible to modify the times for switching on or off by
± 120 minutes. The offset is fixed, i.e. the same for both channels each day.
- The 2-channel design (with the option of assigning separate programmes and modes to each channel)
allows controlling two independent circuits.
- Switching modes:
- Auto - automatic switching mode:
- Programme - switching based on a programme (astro or time).
- Random - switches randomly in a 10 - 120 minute interval.
- Holiday # - holiday mode - option of setting up a period for which the timer will be blocked, i.e. will not
switch based on the set programmes.
- Manual - manual mode - option of controlling the individual output relays manually
- Options of the automatic switching programme:
- Astro - switches based on the time of sunset / sunrise calculated from input date and geographical
location. This time can be corrected ± 2 hours.
- Time programme - switching based on a pre-set time programme
- Memory capacity for 100 time programmes (common for both channels).
- Programming can be performed both when power is on or in backup mode.
- Output relays only operate with a supply voltage of AC 230 V.
- Menu display selection - CZ / SK / EN / ES / PL / HU / RU (default factory setting EN).
- Selection of automatic switching between summer / winter timebased on location.
- Setting the geographic location (selection from predefined options).
- Exact calculation of sunrise and sunset by entering the date, time, latitude and longitude and time
zone.
- Backlit LCD display.
- Simple and easy setup using 4 control buttons.
- Sealable transparent cover on the front panel.
- The timer has a backup battery that preserves data in case of a power supply failure (reserve backup
time up to 3 years).
- Supply voltage: AC 230 V.
- 2-module, mounted onto a DIN rail, clamping terminals.

CONTROL OF A DISPLAY WITH BACKLIGHT
Power on: Display is illuminated with a backlight for 10 seconds from the last button press.
The display continuously shows the settings - date, time, day of the week, contact state and
programme. Permanent on / off is activated by simultaneous presses of the MAN, ESC, OK
buttons. After activating the permanent on/off, the display will flash briefly.
Backup mode: After 2 minutes, the display switches to the sleep mode, i.e. shows no information.
The display can be activated by pressing any button.
- After plugging the timer in for the first time, the current time, date and geographic location must be
set for correct operation of the astronomical clock.

* When is, switched ON constantly with maximal load 16 A / AC1 and ambient temperature
55 °C (131 °F) it is highly reccomended by manufacturer to use conductors with tepmerature
resistive isolation (min) from 105 °C (221 °F) range.
** With temperatures nearing -20 °C (-4 °F), the display quality may be compromised, which does
not hamper the timer’s function.

Warning
CR2032
Device is constructed for connection in 1-phase main alternating current voltage and must
be installed according to norms valid in the state of application. Connection according to the
details in this direction. Installation, connection, setting and servicing should be installed by
qualified electrician staff only, who has learnt these instruction and functions of the device. This
device contains protection against overvoltage peaks and disturbancies in supply. For correct
function of the protection of this device there must be suitable protections of higher degree
(A, B, C) installed in front of them. According to standards elimination of disturbancies must be
ensured. Before installation the main switch must be in position “OFF” and the device should
be de-energized. Don´t install the device to sources of excessive electro-magnetic interference.
By correct installation ensure ideal air circulation so in case of permanent operation and higher
ambient temperature the maximal operating temperature of the device is not exceeded. For
installation and setting use screw-driver cca 2 mm. The device is fully-electronic - installation
should be carried out according to this fact. Non-problematic function depends also on the way
of transportation, storing and handling. In case of any signs of destruction, deformation, nonfunction or missing part, don´t install and claim at your seller it is possible to dismount the device
after its lifetime, recycle, or store in protective dump.
You can change the battery without disassembling the device.
CAUTION
- only change the battery when the device is disconnected from power supply!!!
- the date and time must be reset after changing the battery!!!
- remove the plug-in module with the battery
- replace the original battery
- enter a new battery so that its upper edge (+) lines up with the plug-in module
- slide the plug-in module in the device and pay attention to polarity (+ up) - for roughly 1 s, the
display will show the name and the software version
- you can connect the device to power supply

The numeric value refers to seconds per 10 days. Time correction is factoryset and individual for each product so that the real-time clock would run with
minimum deviation. The time correction value can be arbitrarily adjusted, but
after product RESET, the value returns to factory settings.
