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.

Characteristics
- Serves for controlling of various types of appliances in depend-
ance on real time (automation-switching of heating, pumps,
ventilation etc.). Appliances can be operated in concrete peri-
odic 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 dierent
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), short-
est 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 pro-
grams (it is not possible to set more pulses with dierent dura-
tions 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.
