COMFORT ALERT™ DIAGNOSTICS

The Comfort Alert diagnostics module is a breakthrough innovation for troubleshooting and protecting three phase Copeland Scroll® compressors. The module installs easily in the electrical box of the condensing unit near the compressor contactor. By monitoring and analyzing data from the Copeland Scroll compressor and the thermostat demand, the module can accurately detect the cause of electrical and system related failures and protect the compressor. A fllashing LED indicator communicates the ALERT code and guides the service technician more quickly and accurately to the root cause of a problem.

This module provides compressor protection and will shut down the com- pressor when compressor damaging conditions are detected.

LED DESCRIPTION

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

ALERT LED (Yellow): communicates an abnormal sys- tem condition through a unique fllash code. The ALERT LED will fllash a number of times consecutively, pause and then repeat the process. The number of consecu- tive fllashes, defiined as the Flash Code, correlates to a particular abnormal condition. Detailed descriptions of specific ALERT Flash Codes are shown in two tables attached to this manual.

TRIP LED (Red): indicates there is a demand signal from the thermostat but no current to the compressor is detected by the module. The TRIP LED typically indi- cates the compressor protector is open or may indicate missing supply power to the compressor. A fllashing TRIP LED indicates the anti-short cycle timer is active, preventing compressor from starting.

INTERPRETING THE DIAGNOSTIC LEDS

When an abnormal system condition occurs, the Comfort Alert module displays the appropriate ALERT and/or TRIP LED. The yellow ALERT LED will fllash a number of times consecutively, pause and then repeat the process. To identify a Flash Code number, count the number of consecutive fllashes. Every time the module powers up, the last ALERT Flash Code that occurred prior to shut down is displayed for one minute. If the yellow ALERT LED is on solid more than 2 amps are conducted through the PROT terminal. The contactor coil may be shorted or the PROT terminal miswired.

Some ALERT codes indicate a compressor damaging condition and the Comfort Alert module will shut down and lock out the compressor. Refer to the tables below

to identify ALERT codes that result in a lock out.
