Comfort Alert TM Diagnostics (Select Models) The Comfort Alert TM diagnostics is a break-through innovation for troubleshooting heatpump and air conditioning system failures. Themodule installs easily in the electrical box ofthe outdoor unit near the compressor contac-tor. By monitoring and analyzing data from theCopeland Scroll compressor and the thermostatdemand, the module can accurately detect the

cause of electrical and system related failureswithout any sensors. A ashing LED indicatorcommunicates the ALERT code and guides theservice technician more quickly and accuratelyto the root cause of a problem.

NOTE: This module does not provide safetyprotection! The Comfort Alert module is amonitoring device and cannot shut down thecompressor directly.

LED Description (See Figure 2)

POWER LED (Green): indicates voltage is pres-ent at the power connection of the module.

ALERT LED (Yellow): communicates anabnormal system condition through a uniqueash code. The ALERT LED will ash a numberof times consecutively, pause and then repeatthe process. The number of consecutiveashes, dened as the Flash Code, correlatesto a particular abnormal condition. Detaileddescriptions of specic ALERT Flash Codes areshown in Table 1 of this manual.

TRIP LED (Red): indicates there is a demandsignal from the thermostat but no current to thecompressor is detected by the module. The TRIPLED typically indicates the compressor protectoris open or may indicate missing supply powerto the compressor.

The scroll compressors run (R), common (C) andstart (S) wires are routed through the holes in the

Comfort AlertTM

module marked R, C and S.The common (C) wire need not be routed throughthe module for it to operate properly.

24 VAC Power Wiring The Comfort Alert TM module requires a constant nominal 24 VACpower supply. The wiring to the modules R andC terminals must be directly from the indoor unitor thermostat. The module cannot be powered bythe C terminal on a defrost board or other controlboard without experiencing nuisance alerts.
