Switch timer clock with NFC programming capability
Made in Czech Republic
02-7/2018 Rev.: 0
Characteristics
Description
Digital switch timer clock with day and year program and setting via smartphone supporting NFC
transfer 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 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.
Through simple steps in the application you can set the desired on and off settings based on real
time. You can copy this setting to other days, and altogether you can store up to 100 programs. The
entire setup project can be saved to your smartphone and transferred to the next timer switch. The
smartphone application serves not only to upload settings but also to download. The main benefit
is speed and simplicity.
Near Field Communication is the way of wireless communication of two devices within a short distance
of a few centimeters.
- 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:
- 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.
- Backlit LCD display.
- Simple and easy setup using 4 control buttons or NFC.
- OFF line in-app programs.
- Backup / insertion into the phone memory to transfer to the next switching clock.
- 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.
-When you first connect to the network, it is necessary to set the current time and date for correct
operation.
SHT-7 Setting
SHT-7 can be set up in two ways:
Symbol
1. Using iHC NFC. You can create the desired settings on your mobile phone. Then, by attaching your phone to the SHT-7 you can save your settings to the SHT-7. The application also allows you to save settings
from the SHT-7. You can edit these settings in the same way.
Find the application at:
https://play.google.com/store/apps/details?id=cz.elkoep.ihcnfcsetter
Connection
2. Manual - directly in the SHT-7.

* 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
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. Nonproblematic function depends also on the way of transportation, storing and handling. In case of any
signs of destruction, deformation, non-function 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

Time correction:
The shift unit is 0.1s per day.
The numeric value refers to seconds per 10 days. Time
correction is factory-set 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.
