S-10 COPELAND COMFORT ALERT™

DIAGNOSTICS

Applies to ASX /ASZ and DSX/DSZ units

Comfort Alert™ is self-contained with no required external sensors and is designed to install directly into the electrical box of any residential condensing unit that has a Copeland Scroll™ compressor inside.

Once attached, Comfort Alert™ provides around-the-clock monitoring 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 on following page.)
