Warning
Device is constructed for connection in 1-phase
main alternating current voltage and must be in-
stalled according to norms valid in the state of
application. Connection according to the details
in this direction. Installation, connection, setting and servic-
ing should be installed by qualied electrician sta 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 de-
gree (A, B, C) installed in front of them. According to standards
elimination of disturbancies must be ensured. Before installa-
tion 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 tem-
perature of the device is not exceeded. For installation and set-
ting 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 transporta-
tion, 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.
Internal circuits and sensor circuits are not galvanically isolated
from the mains. No product circuits, including sensor circuits,
can be considered as ELVs.
Cable shield to the sensor, fullls a functional purpose in terms
of EMC does not fulll any protection or safety function and it
is not associated with any EP protection. It is not possible to
touch the shield as well as the other product wiring circuits!
Security against electric shock is ensured by reinforced insula-
tion product, cable, sensors and their correct and professional
installation.
The cable must be of a suitable dimension to meet the pa-
rameters to provide protection in the area of the over-voltage
category III.

Characteristics
Time switch with DCF control is used for the automatic real-
time controlling of appliances. The timer operates all year round
without the need for continuous maintenance, with minimum
operating costs and maximum savings of electrical energy (for
example for turning on heating, pumps, ventilators, public light-
ing etc.). Appliances can be controlled in regular time cycles or
based on a pre-set programme.
Time switch SHT-6 is synchronized by a DCF77 signal using ex-
ternal receiver DCRF-1. Time switch can operate independently
without a DCF receiver. In the case of a power supply interrup-
tion, the timer retains all set values required for its reliable activa-
tion after power is restored.
- 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 indi-
vidual output relay manually
- Options of the automatic switching programme:
- Time programme – switching based on a pre-set time pro-
gramme
- 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
time based on location.
- 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.
- After plugging the timer in for the rst time, the current time,
date and geographic location must be set for correct opera-
tion of the clock.
Settings can be done:
- manually: only if the DCF signal is disabled
- automatically: if the receiver DCFR-1 is connected and DCF
signal is enabled.

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.
