Description
The Intermatic ET8000 Series Electronic Astronomic 7-DayTime Switch automatically switches loads to a preset weekly schedule with to-the-minute accuracy.
•The astronomic feature provides an automatically adjusted sunset ON and sunrise OFF to eliminate the need for separate photo control devices.
•The independent 7-day programming provides complete flexibility for applications where load switching differs each day of the week.
•Astronomic programming can be combined with independent programming to provide a sunset ON and timed OFF program.
Use the ET8000 series as an ON/OFF timer in applications requiring 7-day astronomic load control such as lighting, air conditioning systems, pumps, etc. Each load output of theTime Switch can support up to 14 timed ON and 14 timed OFF events per day as well asAstro ON and Astro OFF events.The program can be overridden by pushing the ON/ OFF load override button(s).
The ET8000 SeriesTime 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 277VAC.

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.

|
|
|
depressing the catch at |
|
|
|
the top of the case and |
|
|
|
pulling out, as shown. |
Slide down |
||
CAUTION: Do not |

touch circuit board |
to remove |
||

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 277VAC, 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.ET8215C 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.

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.
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. 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.
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.
The Time Switch is now ready for programming.

Programming Overview
By pressing the MODE button, theTime Switch will cycle through the menus necessary for programming the current time, date, astro zone, astro events, 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 correctYear.
6.Press the MODE button to exit and advance to setting the time.
2 – Setting Time
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 Astro Zone.
