Warning
Device is constructed for connection in 1-phase main
alternating current voltage and must be installed ac-
cording to norms valid in the state of application.
Connection according to the details in this direc-
tion. 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 pro-
tection 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 inter-
ference. 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 exceed-
ed. For installation and setting use screw-driver cca 2 mm. The
device is fully-electronic - installation should be carried out ac-
cording 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 depend-
ance 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 as-
signed 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 pro-
grams (it is not possible to set more pulses with dierent 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 po-
sitions 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.
