The C.A.M. protects your 3 phase scroll HVAC compressor from nine separate system issues.

The board has nine LED diagnostic alert codes that indicate a system condition by indicator flashes on the module. The flashing LED indicator communicates the alert code and prompts the service technician to more quickly and accurately conduct troubleshooting on Carrier and Bryant condensing units.

The Comfort Alert™ diagnostics module is an innovation for troubleshooting and protecting three phase scroll compressors used in Carrier’s new condensing units and heat pumps. All of Carrier’s 6 thru 20 ton condensing units and heat pumps have this controller as a standard feature, mounted in the control box. The Comfort Alert uses the compressor & system sensors to monitor and analyze system performance. The controller is completely self-contained and mounts in the condensing unit or heat pump. The board has nine LED diagnostic alert codes that indicate a system condition by L.E.D.  indicator flashes on the module. The flashing LED indicator communicates the alert code and prompts the service technician to more quickly and accurately conduct troubleshooting on Carrier’s condensing units.

RED & GREEN LEDS FOR HVAC COMPRESSOR PROTECTION

The module provides three phase compressor protection and will shut down the compressor when potential damaging conditions are detected including missing and reverse phase. There is a Green LED indicator that voltage is present at the Power Connection of the module. There is a Yellow LED indicator that flashes nine different fault codes. This unique code will flash a number of times consecutively, pause and then repeat the process. The number of consecutive flashes, which is defined as the Flash Code, corresponds to a fixed abnormal condition;

1. Long Run Time

2. System Pressure Trip

3. Short Cycling

4. Locked Rotor

5. Open Circuit

6. Open Start Circuit

7. Open Run Circuit

8. Welded Contactor

9. Low Voltage

There is also a Red LED indicator that the compressor has tripped or has no power. The trip Red LED indicates that there is a demand signal from the thermostat or sensor but no current to the compressor is detected by the module. A flashing Red LED indicates the anti-short cycle timer is active, preventing the compressor from starting.
