Installation and User Instructions

Electronic 7-Day
Time Switch

With Battery
Carryover

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 flexibility
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.

WARNING–Risk of Fire or Electric Shock
•	 Electrical shock hazard. To avoid fire, shock, or death, disconnect all
power before installing or servicing time switch or connected loads.
•	 Follow local electrical and safety codes, National Electric Code (NEC)
and Occupational Safety and Health Act Codes (OSHA).
•	 If the power disconnect point is out of sight, lock it in the OFF position
and tag it to prevent unexpected application of power.
•	 This time switch must be grounded.
•	 Do not exceed maximum current carrying capacity.
•	 Always replace the plastic insulator covering the terminal before
powering ON.

Installation Instructions
WARNING: Disconnect the
Snap out catch
power to the Time Switch
Tilt top forward
and the loads before installation.
1.	 Remove the mechanism 	
from the case by de-	
	
	
pressing the catch at the 	
	
top of the case and pull	
	
ing out, as shown.
Slide down
	
CAUTION: Do not
to remove
	
touch circuit board
battery case
	
components since
	
static discharge could damage the microprocessor.
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.)

5.	 Mount the enclosure in the desired location using the 3 mounting holes
	
provided.

9.	 Insert the wire ends under the proper terminal plates (see wiring dia	
grams elsewhere on this page) and tighten the screws firmly.
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 point	
ing 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.

IMPORTANT: Press and hold the ENTER button, then press the RESET button. The screen will flash 12:00 AM and MON, and timer status is Manual
Mode.
NOTE: You must reset the time switch using this procedure whenever you
change the jumpers.

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 AWG#10-#18 copper conductors only.

The Time Switch is now ready for programming.

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
first 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.

1 – 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.

2 – Setting Time

Operating the Time Switch

1.	 If necessary, press the MODE button repeatedly until the words SET
	
and CLOCK appear in the upper area of the display.
2.	 Press the + or – buttons to enter the current time.
	
	 NOTE: To go from AM to PM, keep pressing the + or –
		 buttons to cycle through the day. You can hold the + or – buttons
		 down for 3 seconds to make the time scroll quickly.
3.	 Press the MODE button to exit and advance to setting Events.

Press the MODE button repeatedly to select the desired operating
mode on the display. There are 2 options:
•	 AUTO—where the Time Switch follows the events you have programmed, turning the circuits ON and OFF at the time(s) set.
NOTE: You can override programmed events and force the
Time Switch ON or OFF by pressing the ON/OFF button.
•	 MANUAL—where any events set are disabled and the Time
Switch controls all circuits through the ON/OFF button.
NOTE: You can review or edit any programmed events at any time
by pressing the MODE button repeatedly to return to the appropriate
menu, then following programming instruction provided on this sheet.

If necessary, press the MODE button repeatedly until the words SET
ON/OFF EVENTS and EVENT 01 appear on the display.
If necessary, press the ENTER button to display ON @ or OFF @
(depending on what you want to set).
Press the DAY button to display 12:00 am and all days of the week.
Press the + or – buttons to enter the time you want to set.
NOTE: To go from AM to PM, keep pressing the + or – buttons to cycle
through the day. You can hold the + or – buttons down for 3 seconds to
make the time scroll quickly.
If you want the Event to occur for a combination of days rather than
every day (e.g., weekends only, weekdays only, or individual days),
press the DAY button again as necessary to cycle through the individual days or combination of days you want.
NOTE: To choose a combination not shown during cycling
(e.g., Tuesday and Thursday), you must create an individual event for
each of the days you want.
ET1725C ONLY—For a multi-circuit device with loads set
independently, you can choose the load you want the event to control.
The default setting is for both loads, as you can see on the display.
Press the ON/OFF button under a load to remove the load from the
event.
When you have set the event correctly, you have two choices:
-	 Press the ENTER button to set the next ON/OFF event (up to 28
	 events).
-	 Press the MODE button to exit.

OPTIONAL – Deleting (Clearing) an Event
Use this procedure to clear the settings programmed for an event.
1.	 If necessary, press the MODE button repeatedly until the words
SET ON/OFF EVENTS are shown on the display.
2.	 Press the ENTER button as necessary to cycle through events
that have been set until you see the event you want to delete.
3.	 Press the + or – buttons AT THE SAME TIME to display --:-- --.
4.	 Press the MODE button to exit.

Battery Maintenance
•	 Batteries can be easily replaced without removing the Time
Switch mechanism or field wiring.
•	 Press in and downward (in the direction of the arrows) on the
battery cover.
•	 It is recommended to replace the batteries every 2-3 years with
2 AAA industrial grade alkaline cells as part of normal maintenance on the Time Switch.
•	 Be sure to observe battery polarity markings when installing
batteries.
•	 No other battery maintenance is required.
