- Serves for controlling of various types of appliances in dependance on real time

(automation-switching of heating, pumps, ventilation etc.). Appliances can be op-

erated 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 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), 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 pos-

sible to set more pulses with dierent 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 volt-

age 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 dis-

played also in back-up mode.

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

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

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 in-

terference. By correct installation ensure ideal air circulation so in case of permanent opera-

tion 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.
