Section 1: Introduction
Congratulations on your purchase! Your ChronTrol XT is a programmable,
microprocessor-based timer that can control up to 16 devices (outputs) and
can receive inputs from up to 8 external devices. The XT can easily be
programmed to switch circuits on and off at specific times and dates, for
durations, on a cycle, or from external devices attached to its optional input
connector. 20 to 40 timing programs can be stored in the XT’s memory.
The XT can be programmed down to the second. Its versatile calendar
automatically adjusts for leap years, Daylight Saving Time and holidays.
Programs are easy to set, review, and change through the 24-pushbutton,
audible keyboard.
The XT family includes four basic models: table-top, wall-mount, expandable
wall-mount, and rack-mount. Table-top models are available with two or
four circuits, AC outlets or dry contacts. All other models are available in
two- to sixteen-circuit configurations with dry contact outputs rated up to 20
Amps. The
SPECIFICATIONS AND INSTALLATION
sheet for your
particular ChronTrol model is included with your unit. Specification sheets
for other types are available upon request. The features and programming
techniques described in this manual apply to all models of the XT.
