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.
