- Page 2 ™ Comfort Alert Diagnostics – Faster Service And Improved Accuracy 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.

- Page 7 PROT Terminal The PROT terminal provides the compressor protection functionality for Comfort Alert. If a compressor damaging code is active, the PROT terminal interrupts the common leg of the compressor contactor coil. This terminal is rated for a maximum of 1 Amp (24 VA) and is only compatible with AC coils.
- Page 8 still active. The TRIP LED will again fl ash for the duration of the anti short cycle time, after the anti short timer expires, the Trip LED will illuminate and remain solid as long as the compressor power remains disconnected and demand is still present. If the red LED does not function as described, refer to Table 1 to verify the wiring.
- Page 9 Module locks out compressor when compressor damaging ALERT codes appear Lockout ALERT codes are noted in the Status LED Description During a compressor lock out, 24VAC power must be removed from module to manually reset Yellow “ALERT” A short circuit or over 1.

- Page 11 NOTE: The correct Comfort Alert model must be used for the application (refer to the Product Specifi cation section on page 2). If the wrong model is installed, the ALERT Flash Codes for system faults will function incorrectly: the Comfort Alert module may indicate system faults that are not present or fail to indicate system faults that are present.
