EL74, EL78 and EL712 Series has it all. These controllers have 4,
8 and 12 relays, respectively, and have every feature an
industrial, commercial or municipal application could possibly
require engineered into it. This series can be used as 24-hour,
7-day, 365-day controls with daylight savings time, leap year
adjustment and selectable SunTracker™ controls. Y2K compatible,
they are easy to program with each control allowing up to 128 ON
or OFF events, 34 holidays and 32 sensor events.

FEATURES
& BENEFITS
 |
96-Hour
Carryover, unique to Paragon, protects scheduled events from
power interruptions via a capacitor-more reliable than
batteries. |
|
Resolution enhancements allow 4 user-defined duty cycle patterns;
4 user-defined durations are available from 1 second to 23
hours, 59 minutes, 59 seconds. |
|
ON/OFF
events can be controlled by temperature, light or other
sensors. |
|
Enabler
switch allows an ON event to be selected without
pre-programming the event. |
|
|
Pecosoft.EL
software and CIMI Adaptor (each sold separately) allow
remote programmability. |
|
User-friendly
keypad and easy-to-read digital time display take the
frustration out of programming. |
|
Remote
override allows immediate reaction to unexpected events
without affecting pre-programming or visiting the clock
site. |
|
UL and CSA listed
means quality and durability are built into every
time control. |
|
Title 24
certified. |

HOW TO SPECIFY
Installer shall
furnish and install Paragon EL74, EL78 Eight Channel (or
EL712 Twelve Channel) Electronic Time Control. The control
shall have 24-hour, 7-day, 365-day or SunTracker™
capability with 128 events available. It shall also have 4
user-definable durations and duty cycle lengths plus
automatic daylight saving time and leap year adjustments.
Control shall have remote override capabilities (timed,
toggle or enable type). Control shall have keyboard override
until overridden again or until next event is reached. It
shall be capable of switching loads based on user-definable
temperature and light levels with 32 events available.
Control shall have momentary (latching relay) capability and
shall have Astro features plus 30 definable holidays and 6
pre-programmed holidays. Control shall provide 2 days of
power outage carry-over without a battery. Control shall
provide 10 years of power outage protection with a battery.
The digital time display shall be 3/4” in height. Clock
format shall be selectable, allowing a choice of 12 hour
(AM/PM) or 24 hour format. Control shall be capable of
interfacing (sending and receiving data) with a personal
computer. Power input terminals shall have the capability to
accommodate #12 to #18 AWG wire. Control shall be housed in
a NEMA 1, lockable steel enclosure, to guard against
vandalism or tampering.

Power Outage
Carry-Over
The program and time of day are maintained during a power
outage for a minimum of 2 days by means of a capacitor.
After two days, a lithium battery takes over and provides a
minimum accumulated carryover of 1 year. The lithium battery
should provide over 10 years of carryover protection.
