Installation and User Instructions

MODEL ET1100 Series

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 requiring

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 tungsten

or ballast loads up to its rating, and inductive or resistive loads up to

30 A at 120, 208, 240, or 277 VAC.

WARNING

Risk of Fire or Electric Shock

• 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.

1. Remove the mechanism

from the case by

depressing the catch at

the top of the case and

pulling out, as shown.

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. 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

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.)

Enclosures—ET11x5C – TYPE 1 indoor metal enclosure

Knockouts—Combination 1/2-3/4 inch size, 1 on back and each side,

2 on bottom

Wire Size—AWG #18 through #10

2. Set voltage selector for desired input voltage.

The timer is shipped with voltage set for 277

VAC. To operate at 120, 208 or 240 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.

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 diagrams 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.

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.
