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 qualied 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 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, 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.

Characteristics
- Serves for controlling of various types of appliances in
dependance on real time (automation-switching of
heating, pumps, ventilation etc.). Appliances can be
operated in concrete periodic time cycles or according
a pre-set program (depends on type, see the chart
Versions of time switches).
- SHT-1, SHT-3: 1-channel version.
- SHT-1/2, SHT-3/2: 2-channel version (to each channel
can be assigned an individual program).
- Possibility to control two independent circuits.
- By SHT-3, SHT-3/2 is not possible to integrate daily and
night mode on one channel. By SHT-3/2 is possible to
set a dierent mode on each channel.
- Setting of switching by:
- program (PROG) - switching according programs set
in SET 1 . Possibility to set the repeat every minute or
every hour.
- random (AUTO ) - random switching in 10-120 min interval.
- permanently manualy .
- Switching modes (OUT):
- OUT ON - normal - 2 positions in memory (close /open),
shortest time of closing is 1 min.
- OUT ON - cyclic - 2 positions in memory (pulse/delay),
range 1-99s.
- OUT ON - pulse - 1 position in memory, range 1-99s.
- OUT OFF - turn o the switching mode.
- Set time of pulse/delay is on one channel the same for
all programs (it is not possible to set more pulses with
dierent durations on one channel).
- “Holiday mode - “ - possibility to choose the period,
when the device will be not switching according a
standard program and will be blocked for the pre-set
time.
- 100 memory positions (by SHT-1/2 and SHT-3/2 are
those 100 positions common for both channels).
- Programming of device can be realize even under
voltage and also even in back-up mode.
- Output relays operates only under voltage.
- Automatic change-over between summer/winter time
(setting is for time zone GTM+1:00).
- Back-lighted LCD display.
- Easy and quick setting by 4 control buttons.
- Sealable transparent cover of the front panel.
- Time switch is back-up with in-built lithium element,
which saves data during voltage failure. Back-up time
reserve - up to 3 years.
- Supply voltage: AC 230V or AC/DC 12-240V.
- 2-Module, DIN rail mounting, saddle terminals.
- Device is delivered with pre-programmed actual time,
which is permanently displayed also in back-up mode.
