Installation and User Instructions
Description
The Intermatic ET1100 Series Electronic 24-Hour Time Switch
automatically switches loads to a preset daily schedule with to-the-
minute accuracy.
Use the ET1100 series as an ON/OFF timer in applications requir-
ing 24-hour 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 ET1100 Series Time Switch is designed to directly switch tung-
sten 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
power to the Time Switch
and the loads before instal-
lation.
1.
Remove the mecha-
nism from the case by
depressing the catch at
the top of the case and
pulling out, as shown.
CAUTION: Do not
touch circuit board
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 Sav-
ing 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.
ET1125C 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 con-
tactors 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.)
