- 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 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 pos-
sible 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 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.
