Introduction
The EL7100 and EL7200 are one and two-channel, electronic time controls that provide
simple, inexpensive control of lighting, HVAC, motors, pumps, or any electrical load with a
time-of-day schedule. The control may be utilized as a 24 hour, 7 day or full year (365 day)
control.
The EL series allows for the programming of 128 events. An event could be an ON or an
OFF.
The EL series of time controls are versatile, yet easy to program. A simple keypad com-
bined with a large, user-friendly display takes the frustration out of programming.
Specifications
Programming Capabilities
• 128 Events - An event can be an ON or an OFF. Each event can be assigned to either
channel. Each event can be assigned to any day or any combination of days, including
the three holiday schedules.
• Optional Daylight Savings Correction - Programmable as a day of the month (i.e. 1st
Sunday in April / last Sunday in October)
• Leap Year Correction to the Year 2100
• 30 Single Day Holidays - (e.g. July 4th)
• 30 Day of Month Type Holidays - (e.g. last Monday in May)
• 30 Holiday Durations - Programmable from 1 to 366 days (e.g. June 9th to August 27th)
3

• 6 Specific Holidays - Each holiday can be optionally selected
Good Friday Easter Sunday Easter Monday
Boxing Day Victoria Day Thanksgiving Thursday and Friday
• 3 Holiday Schedules - Each of these 96 holidays can be assigned to one of three holiday
schedules (A,B or C). For example, if July 4th is assigned to holiday schedule A, then on
July 4th only those events containing holiday A in their day fields will be executed.
• Keyboard Override - Toggles the current output state; begins immediately when initiated and
remains in effect until overridden again or until the next programmed event occurs.
• Selectable Clock Format - 12 hour (am/pm) or 24 hour clock format.
• Momentary - The EL7200 has two relays. This control can be configured for either main-
tained or momentary, operation. The momentary option is intended for use with latching
relays. When configured for momentary the EL7200 will have only one channel; Relay #1 will
provide a 1 second latching ON pulse and Relay #2 will provide a 1 second latching OFF
pulse. The EL7100 only has one relay, therefore it does not have momentary capability.

Programming
Programming Overview:
After pressing the PROGRAM key, the EL7100 and EL7200 will continue to control the outputs
based on the events that were operating at the time the PROGRAM key was pressed. The
control will not check for new events until it has gone through a status update.
The control remains fully functional after pressing the REVIEW key, provided the REVIEW key
wasn't pressed while in the programming mode.
During operation, the control will be in the RUN mode. When programming (or reviewing), the
order of the program headers and steps is as follows:
TIME - set time, date, daylight savings time
EVNT - on, off
HOL - set holidays
From the HOL header, the control will loop around to the TIME header. The OVER (over-ride)
mode is only accessible from the RUN mode. The following is a detailed explanation of each
mode.
In all modes use the NEXT key to advance to the next item to be programmed or reviewed,
and the PREVIOUS key to go back to the previous item. Use the + and - keys to modify the
current (flashing) item.
12

Memory Clear
Indicates that the memory has been cleared. Use the NEXT key to begin program-
ming. After initial power-up or a reset, the control will be in MEM CLR (memory
clear) mode. This mode is only accessible once.
Toggle between MAINtAin (maintained) or MOMNtARY (momentary) operation using
the +/- key. When configured for momentary, Relay 1 will provide the ON pulse and
Relay 2 will provide the OFF pulse. An EL7200 configured for momentary operation
will become a one-channel control. Use the NEXT key to continue programming.
(The EL7100 does not have this screen.)
Toggle between 12 hour (AM/PM) or 24 hour (00:00-23:59) clock format using the
+/- key.
NOTE: After selecting relay operation and clock format, press the PROGRAM key to
begin the programming steps in the TIME header.
13

Set Time
Set Time header. This mode is used for setting time, date and daylight savings time.
Use the NEXT key to begin programming.
Program hours, minutes, seconds and day of week using the +/- key. A PM indica-
tor is used in the 12 hour format. AM begins with midnight and PM begins with
noon. NOTE: Only the PM indicator will appear in the 12 hr format.
Program month, date and year.
To disable Daylight Savings Time operation, select NO.
Program the day that Daylight Savings Time begins. The control defaults to the first
Sunday in April. At 2:00 AM on this day, the control's time will advance one hour.
Program the day that Daylight Savings Time ends. The control defaults to the last
Sunday in October. At 2:00 AM on this day, the control's time will go back one hour.
14

Events
Events header. Up to 128 events can be programmed. Events can be an ON or an
OFF. An event can be assigned to either channel. Each event can be assigned to
any day or combination of days including the 3 holiday schedules (A, B and C). Use
the NEXT key to begin programming.
The +/- keys will quickly step thru the events when the event # is flashing. Select
the event type, select the channel and program the hours and minutes while each of
these parameters are flashing using the +/- key.
Select YES for each day that is to be included in this event.
15

Holiday
Holiday header. The four holiday types with their priorities are as follows:
SPEC (special) - highest priority
DATE (month/date) - 2nd highest priority
D/WK (day of week) - 3rd highest priority
SPAN (duration) - lowest priority
To demonstrate the use of priorities, assume that Thanksgiving Break (SPEC) is pro-
grammed as a holiday schedule B. Also assume that Nov. 1st to Nov. 30th (SPAN) is
programmed as a holiday schedule A. Then on Thanksgiving Day and the Friday
after, the control will execute the events that include HOLIDAY B in their day field,
since SPEC is a higher priority than SPAN. The rest of November the control will use
events that include HOLIDAY A in their day fields. The other 11 months (assuming
no other holidays) will be controlled according to the events programmed for the
normal days (SUN - SAT).
16

Special Holiday type. Each of 6 special holidays can either be assigned as one of
the 3 holiday schedules A, B or C or not selected. Press the NEXT key to program
the special holidays (starting with Good Friday) or press the +/- keys to move to a
different holiday type (e.g. Date).
Good Friday
Easter Sunday
Easter Monday

Thanksgiving Break (Thursday and Friday)
Boxing Day
Victoria Day
Holiday Date type. Up to 30 date type holidays can be programmed.
NONE indicates that this holiday (date) number (1-30) is not used (no holiday sched-
ule has been selected). Press the NEXT key to program this holiday (date) or press
the +/- keys to move to other holiday (date) number(s).
18

Program the month, date and holiday schedule while each of these parameters are
flashing. To remove a date type holiday, select none of the schedules.
Day of Week Holiday type. Up to 30 days of week type holidays can be pro-
grammed. Examples of day of week type holidays are:
1st Monday in September
Last Monday in May
NONE indicates that this holiday (day of week) number (1-30) is not used (no holiday
schedule has been selected). Press the NEXT key to program this holiday (day of
week) or press the +/- keys to move to other holiday (day of week) numbers.
This screen shows holiday #2 is programmed as the 1st Sunday in January with hol-
iday schedule A assigned. Program the month, week no.(1st, 2nd, 3rd, 4th or last),
day and holiday schedule while each of these parameters are flashing. To remove a
day of week type holiday, select none of the schedules.
19

Holiday Span type. Up to 30 holiday durations can be programmed. A holiday dura-
tion is defined with a beginning date and an ending date. A holiday duration can be
programmed as a single day holiday by making the ending date the same as the
beginning date. It is OK to have the holiday duration extend into the next year.
NONE indicates that this holiday (span) number (1-30) is not used (no holiday
schedule has been selected). Press the NEXT key to program this holiday (span) or
press the +/- keys to move to other holiday (span) numbers.
Program the beginning month and date for holiday duration #1.
Program the ending month and date for holiday duration #1. Then select a holiday
schedule A, B or C. To remove a holiday duration, select none of the schedules.
