INTRODUCTION This easy to program microprocessor-based time switch provides flexible 24-hour, 7 day or full year load control. Its unique “self-prompting” feature simplifies programming by leading you through with flashing prompts. The 2 rows of LEDs on the left side flash and indicators in the digital display light while you are programming to identify information that needs to be entered. SET UP information must be entered first, followed by the PROGRAM information.
KEYPAD SET UP SET UP is performed once during installation to set the internal CLOCK, ASTRO (sunrise/sunset) times and HOLIDAY references. After entering and okaying the ASTRO Zone, the timer will display calculated “center of time zone” times when prompting for sunrise and sunset entries. You may OK these, enter actual sunrise/sunset times or enter offset times for early or late ASTRO operation. Sunrise time must be before noon; sunset time must be after noon. Sunset must not be within 5 hours of sunrise.
and time, as is normal INTVL. To initiate an override interval, set the RUN/SET switch to RUN, set the switch for the desired load to Enable, press the INTVL key and hold, and press the ON/OFF button for the load you wish to override. The green load indicator flashes during the interval to show override selection. At the end of an override interval the load and green LED will turn off, regardless of the load state before the override or prior programmed schedules.
Holiday schedules and dates will remain in timer memory until deliberately cleared. For those Holidays whose dates vary from year to year, you must manually revise the start and stop dates (in SET UP review) annually. Holidays may not be programmed to end before their start date and must end by Dec. 31. 4) The COPY feature copies the programmed schedules of all the circuits of the copy from day to the corresponding circuits of the copy to day regardless of the positions of the circuit Enable switches.
If a soft start other than the factory setting of 15 seconds is desired press SET UP; and the date will be displayed. Then press PULSE: SS (for Soft Start) appears in the left two displays with 3 dashes in the rightmost displays. Enter the soft start desired by keying in a number from 1 to 127 seconds, and then press OK. This new soft start allows you to lengthen or shorten the 15-second soft start and will affect all available circuits.
REVIEW INDIVIDUAL DAY, DAY GROUP, OR COPIED ACTIVITIES • Press PROG, then press the day key (SUN/1 through SAT/7) or the day group key (wkDY/8, wkND/9 or ALL/0) to select the day or day group to review. NOTE: If you have entered data as a day group and attempt to review any of the days individually, the message “End of Review” will be displayed. This is because you must review data just as it was entered, in this example, as a day group. • Press REV, at which point the colon will disappear.
• During automatic review, the OK key must be used to pause the display before the displayed data can be deleted. • After any program data is cleared, review is terminated. The timer is now in the program mode for the selected day, anticipating a new entry. You may make the new entry, restart review, or return to Run position. • It is recommended that you repeat the "week long review" after any revisions are complete to verify that all revisions were implemented as desired.
Set Press Load slide switches to Enable Load 1and Disable 2 SAT/7, OK (selects Saturday only); 7, 5, 0, AM, OK (load On time); 1, 2, 0, 0, PM, OK (load Off time) Scheduled PROGRAM is now complete. Assume A 30 min. INTERVAL override duration is desired for Load 1.

TIME ZONES After the astro zone is entered the approximate sunrise and sunset times for the center of the time zone will be displayed. Depending on your location relative to the center, you may want to change (offset) this time. Following are approximate offsets (plus or minus) for selected cities in 5 minute increments.
SPECIAL INSTRUCTIONS Slot for removal Enclosure Mounting Follow the instructions included with the 2 mounting brackets. They have several holes (3 are slotted) for securing the enclosure. Mount using suitable hardware. For ease of installation the cover can be removed by lifting upward off the hinges. WARNING: Disconnect all power at the service panel before removing the logic module. Removing Logic Module (required for wiring). Remove the 4 Philips Head screws and set them aside for reinstallation.
SPECIAL INSTRUCTIONS Remote Override To obtain access to the remote override connector for circuits 1–4, remove the two screws as shown from the connector insulator. Then loosen the remaining screw 1/2 turn and pivot the insulator to the left, out of the way of the remote override connector. Route wiring and insulating tube around the control relays.
TYPICAL WIRING CONFIGURATION 24 Volt Models (ET70815CR24 shown) WARNING: Connect 24 VAC 60 Hz only to 24V timer power terminals. NOTE: To enable switching loads of a voltage different than the timer power voltage, the outputs from this timer are isolated relay contacts. You need to connect a source of power to the common (COM) terminals as shown above. Do not mix solid and stranded wires under the same terminal.
Problem Load Switches at Incorrect Time Solution(s) • Using the REV function, check program times against the times you entered in the chart. • Review SETUP to see if the timer is following a holiday schedule. Holiday dates and schedules from the prior year do not automatically clear or adjust. They must be manually revised or removed annually. • When using pulse or interval “On” programming, the load will switch On at the scheduled time and Off at that time, plus the pulse or interval duration.
Problem Solution(s) Events programmed via Day Group or Copy Day methods will not show when reviewing individual days or vice versa. Difficulty in • When using pulsed output for switching a Programming/ latching relay or contactor without “selfReviewing On/ clearing” contacts, one circuit is dedicated to Off Latching the load Turn On Pulse and another to the Pulse Turn Off Pulse. The pulses are created by or turning the respective circuits On momentarily Output to (1 to 2 sec.).
