Miswiring the Comfort Alert module will cause false LED codes. Table 1 describes LED opera-
tion when the module is miswired and what troubleshooting action is required to correct the
problem.
Installation Verification
To verify the installation of Comfort Alert is correct, a functional test can be performed. Force a call for cooling and
when the compressor starts to run, monitor the yellow ALERT LED. The LED should remain off during test. Disconnect
power to the compressor while the call for cooling is still active. The red TRIP LED will flash indicating the anti-short
cycle timer is active. If the red LED does not function as described, refer to Table 1 to verify the wiring.
