COMFORT ALERT DIAGNOSTIC The POWER LED indicates the presence of control power to the CADM. MODULE POWER The Comfort Alert Diagnostic Module (CADM) monitors (GRN) and analyzes data from the Copeland Scroll three-phase compressor and the thermostat demand. The CADM also provides a 3-minute anti-recycle time delay to compressor cycling.
