Installation and User Instructions
WARNING
• Disconnect power at the circuit breaker(s) or disconnect switch(es) before installing or servicing.
• Installation and/or wiring must be in accordance with national and local electrical code
requirements.
• For outdoor locations or wet locations (rain-tight), conduit hubs that comply with requirements of
the UL514B (standard for fitting conduit and outlet boxes) are to be used.
• This enclosure does not provide grounding between conduit connections. When metallic conduit
is used, you must also install grounding type bushings and jumper wire.
• For plastic enclosures, bonding between conduit connections is not automatic and must be
provided as part of the installation.
• Use #18 - #10 AWG wires, rated at least 75°C - COPPER conductors ONLY.
• If the power disconnect point is out of sight, lock it in the OFF position and tag it to prevent
unexpected application power.
• Make sure there is no wire insulation under the terminal plate on the time switch connector.
Firmly tighten terminal screws.
• Do not remove insulator that is covering terminals.
• KEEP DOOR CLOSED AT ALL TIMES when not servicing.
NOTICE
• Do NOT touch circuit board components, contact can create a static discharge, which can
damage the microprocessor.
Description
The Intermatic ET1700 Series Electronic 7-Day Time Switch
automatically switches loads to a preset weekly schedule with to-theminute accuracy.
The independent 7-day programming provides complete exibility for
applications where load switching differs each day of the week.
Use the ET1700 series as an ON/OFF timer in applications requiring
7-day load control such as lighting, air conditioning systems, pumps,
etc. Each load output of the Time Switch can support up to 14 timed
ON and 14 timed OFF events per day. The program can be overridden
by pushing the ON/OFF load override button(s).
The ET1700 Series Time Switch is designed to directly switch tungsten
or ballast loads up to its rating, and inductive or resistive loads up to
30A at 120, 208, 240, or 277 VAC.

Installation Instructions
1. Remove the mechanism
from the case by
depressing the catch at
the top of the case and
pulling out, as shown.
2. Set voltage selector for desired input voltage.
The timer is shipped with voltage set for 120
VAC. To operate at 208, 240 or 277 VAC, move
the selector switch to the desired setting as
marked on the circuit board. See location A in
Rear View above and detail at the right.
3. The timer is shipped with DST (Daylight Saving
Time) enabled. To disable DST, insert a jumper
at location marked DST. See location B in Rear
View above and detail at the right.
4. ET1725C ONLY—Decide whether you want
to control multiple loads simultaneously (SIM),
independently (IND), or with a 2-second pulse
(PUL) (e.g., for use with mechanically held
contactors or bell ringing applications), and
make sure the jumper is positioned accordingly.
See location B in Rear View above and detail
at the right. (The unit is shipped with the loads
set for IND.)

9. Insert the wire ends under the proper terminal plates (see
wiring diagrams elsewhere on this page) and tighten the
screws rmly.
10. Connect ground wire to grounding terminal at bottom of enclosure.
11. Replace the plastic insulator on the retaining post.
12. Remove the battery case by sliding it down as shown by the
arrows, then install 2 AAA alkaline batteries. Make sure the
batteries are pointing in the direction shown.
13. Verify that the display is ON to make sure the batteries are OK.
If the display shows scrambled information, press the RESET
button to clear it up.
14. Apply power to the Time Switch.

Knockouts
Position at eye level if possible, providing space to the left of the
enclosure for the cover to swing open fully, as shown.
6. Replace the mechanism in the enclosure.
7. Lift the left side of the plastic insulator off the retaining post and
pivot it up and away to expose the terminal strip.
8. Strip the supply and load wires to 1/2”. Use #18 -
#10 AWG wires, rated at least 75°C - COPPER
conductors ONLY.

Programming Overview
By pressing the MODE button, the Time Switch will cycle through the
menus necessary for programming the current time, date, and timed
events.
The basic procedure is to use the MODE button to move from one
menu to the next (e.g., DATE, TIME, etc.), the + or – buttons for the
rst part of a setting (e.g., MONTH), the ENTER button to move to the
next part of the setting (e.g., YEAR), then MODE to exit and move to
the next menu. To skip a menu, press MODE to move ahead.
If you make a mistake, press the MODE button repeatedly to
cycle back around to the error, then make the correct entry.
NOTE: DATE and TIME must be set before you can access any
other programming menus.
Setting Date
1. Press the MODE button repeatedly until the words SET and
DATE appear in the upper area of the display.
2. Press the + or – buttons to enter the current Month.
3. Press the ENTER button when the Month is correct to save the
setting. The screen advances to current Date.
4. Again press the + or – buttons to enter the current Date,
followed by the ENTER button.
5. Repeat to set the correct Year.
6. Press the MODE button to exit and advance to setting the time.
