EC72, EC72D
Electronic Time Controls
DESCRIPTION
The EC72 and EC72D are seven-day, two-channel time controls that
will switch two different electrical circuits according to a pre-set, time-
of-day program, thus providing precise control of those circuits from a
central location and common time base. Once programmed, the con-
trols will automatically turn loads ON and OFF according to your
schedule, compensating for changes in Daylight Savings Time, adjust-
ing for Leap Year and altering ON/OFF events on designated holidays.
APPLICATIONS
The EC72 Series provides ideal control for indoor and outdoor lighting,
heating, ventilation and air conditioning, and motors, pumps and fans
in convenience and retail stores, commercial buildings, industrial facil-
ities, schools and churches. The Momentary Option, accessed by clip-
ping a jumper wire, provides a two-second momentary contact closure
ideal for ringing school bells and church chimes or operating latching
relays. The 12-volt DC model is ideal for battery-powered applications
such as security systems, remote deer feeders and air sampling
machines.
Both Models possess identical programming capabilities. The differ-
ences between the controls lie in housing - the EC72 is enclosed in a
NEMA 1 indoor metal case, while the EC72D is a DIN model, housed
in an indoor plastic case.
5
The EC72D typically is used in indoor or outdoor panels. The EC72 is
used for indoor stand-alone applications.
PROGRAMMING CAPABILITIES
• True 7-Day Programming - each day of the week can be uniquely
programmed.
• 16 Events per Channel - up to 16 ON/OFF events can be pro-
grammed for each channel.
• Repeat Programming - simplifies programming and increases the
total number of events through daily repetition of certain ONs and
OFFs; creates a maximum of 112 events per week per channel.
• Holiday Programming - twelve single-day holidays and two holiday
durations are programmable by date.
• Daylight Saving Time - can be programmed for automatic
changeover in the spring and fall.
• Automatic Leap Year Correction
• Momentary Option - any EC72 Series model can be converted to a
momentary output control by clipping a jumper wire; all events
become ON events of two-second duration. (See page 22.)
• Manual Override - temporarily reverses current output state; begins
immediately when initiated and remains in effect until overridden
again or until the next programmed event; each channel can be over-
ridden independently.

POWER OUTAGE CARRYOVER
Program and Time-of-Day Backup - 100 hours of carryover with a 9-
volt alkaline battery. 275 hours of carryover with a 9-volt lithium bat-
tery (Ultralife, U9VL.) Battery not provided. During a power outage, the
time and program are maintained, but the output relays remain de-
energized.
ENVIRONMENTAL
The EC72 Series should be mounted indoors in an environment that is
free from excessive contaminants such as oil, moisture and dirt or in
an appropriate outdoor panel. For outdoor use, an EC72D can be
mounted in a NEMA 3 enclosure 4010EC (X9092) which must be pur-
chased separately.
