HIGH VOLTAGE!
Disconnect ALL power before servicing
or installing. Multiple power sources
may be present. Failure to do so may
cause property damage, personal injury
or death.
The CoreSense™ module is self-contained with no required exter-
nal sensors and works with any residential condensing unit that
has a Copeland Scroll™ compressor inside.
Once attached, CoreSense™ provides around-the-clock monitor-
ing for common electrical problems, compressor defects and
broad system faults. If a glitch is detected, an LED indicator
flashes the proper alert codes to help you quickly pinpoint the
problem. See Diagnostic Table: 2-Wire Comfort Alert™ Module on
following pages.)
