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.
